Title: Sole plate for an article of footwear

Description:
BACKGROUND 
     The present embodiments relate generally to articles of footwear and including removable motorized adjustment systems. 
     Articles of footwear generally include two primary elements: an upper and a sole structure. The upper is often formed from a plurality of material elements (e.g., textiles, polymer sheet layers, foam layers, leather, synthetic leather) that are stitched or adhesively bonded together to form a void on the interior of the footwear for comfortably and securely receiving a foot. More particularly, the upper forms a structure that extends over instep and toe areas of the foot, along medial and lateral sides of the foot, and around a heel area of the foot. The upper may also incorporate a lacing system to adjust the fit of the footwear, as well as permitting entry and removal of the foot from the void within the upper. Likewise, some articles of apparel may include various kinds of closure systems for adjusting the fit of the apparel. 
     SUMMARY 
     In one aspect, the present disclosure is directed to a sole plate for an article of footwear, comprising a forward portion, an intermediate portion, and a rearward portion, as well as a longitudinal axis, a lateral axis, and a midline. There is a compartment disposed within the intermediate portion, and the compartment comprises a cavity. There is also a central axis extending in a direction aligned with the longitudinal axis extending from the forward portion to the rearward portion. The central axis is approximately aligned with the midline of the sole plate, and the central axis divides the sole plate into two opposing sides along the lateral axis. The two sides of the sole plate comprise a first side and a second side, and the forward portion is disposed substantially toward the first side relative to the rearward portion, such that the forward portion and the rearward portion are laterally offset with respect to one another. 
     In another aspect, the present disclosure is directed to a sole plate for an article of footwear, comprising a forward portion, an intermediate portion, and a rearward portion, and a longitudinal axis, a lateral axis, and a midline. There is a compartment disposed within the intermediate portion, where the compartment comprises a cavity. Furthermore, there is a central axis extending in a direction aligned with the longitudinal axis extending from the forward portion to the rearward portion, the central axis being approximately aligned with the midline of the sole plate. The central axis divides the sole plate into two opposing sides along the lateral axis, and the two sides of the sole plate comprise a first side and a second side. The forward portion extends a first distance from the central axis toward the first side, the rearward portion extends a second distance from the central axis toward the second side, and the first distance is greater than the second distance. 
     In another aspect, the present disclosure is directed to a sole structure for an article of footwear, comprising a forefoot region, a heel region, a longitudinal axis, a lateral axis, and a midline, and a central axis extending in a direction aligned with the longitudinal axis extending from the forefoot region to the heel region. The central axis is approximately aligned with the midline of the sole structure, and the central axis divides the sole structure into two opposing sides along the lateral axis. The two sides of the sole structure comprise a first side and a second side. Furthermore, the sole structure includes a sole plate and a midsole, where the sole plate is disposed adjacent to the midsole, and where the sole plate includes a forward portion, an intermediate portion, and a rearward portion. A compartment is disposed along the intermediate portion, and the compartment comprises a cavity. In addition, the midsole includes a first portion, a bridge portion, and a second portion, where the midsole includes two open regions associated with the bridge portion, and where the two open regions include a first open region and a second open region. The bridge portion is disposed adjacent to a portion of the intermediate portion, where the first open region creates a first exposed area of the cavity toward the first side, where the second open region creates a second exposed area of the cavity substantially toward the second side, and where a size of the first exposed area is smaller than a size of the second exposed area.

     DETAILED DESCRIPTION 
     The following discussion and accompanying figures disclose articles of footwear and a method of assembly of an article of footwear. Concepts associated with the footwear disclosed herein may be applied to a variety of athletic footwear types, including running shoes, basketball shoes, soccer shoes, baseball shoes, football shoes, and golf shoes, for example. Accordingly, the concepts disclosed herein apply to a wide variety of footwear types. 
     To assist and clarify the subsequent description of various embodiments, various terms are defined herein. Unless otherwise indicated, the following definitions apply throughout this specification (including the claims). For consistency and convenience, directional adjectives are employed throughout this detailed description corresponding to the illustrated embodiments. 
     The term “longitudinal,” as used throughout this detailed description and in the claims, refers to a direction extending a length of a component. For example, a longitudinal direction of an article of footwear extends between a forefoot region and a heel region of the article of footwear. The term “forward” is used to refer to the general direction in which the toes of a foot point, and the term “rearward” is used to refer to the opposite direction, i.e., the direction in which the heel of the foot is facing. 
     The term “lateral direction,” as used throughout this detailed description and in the claims, refers to a side-to-side direction extending a width of a component. In other words, the lateral direction may extend between a medial side and a lateral side of an article of footwear, with the lateral side of the article of footwear being the surface that faces away from the other foot, and the medial side being the surface that faces toward the other foot. 
     The term “side,” as used in this specification and in the claims, refers to any portion of a component facing generally in a lateral, medial, forward, or rearward direction, as opposed to an upward or downward direction. 
     The term “vertical,” as used throughout this detailed description and in the claims, refers to a direction generally perpendicular to both the lateral and longitudinal directions. For example, in cases where a sole is planted flat on a ground surface, the vertical direction may extend from the ground surface upward. It will be understood that each of these directional adjectives may be applied to individual components of a sole. The term “upward” refers to the vertical direction heading away from a ground surface, while the term “downward” refers to the vertical direction heading towards the ground surface. Similarly, the terms “top,” “upper,” and other similar terms refer to the portion of an object substantially furthest from the ground in a vertical direction, and the terms “bottom,” “lower,” and other similar terms refer to the portion of an object substantially closest to the ground in a vertical direction. 
     The “interior” of a shoe refers to space that is occupied by a wearer&#39;s foot when the shoe is worn. The “inner side” of a panel or other shoe element refers to the face of that panel or element that is (or will be) oriented toward the shoe interior in a completed shoe. The “outer side” or “exterior” of an element refers to the face of that element that is (or will be) oriented away from the shoe interior in the completed shoe. In some cases, the inner side of an element may have other elements between that inner side and the interior in the completed shoe. Similarly, an outer side of an element may have other elements between that outer side and the space external to the completed shoe. Further, the terms “inward” and “inwardly” shall refer to the direction toward the interior of the shoe, and the terms “outward” and “outwardly” shall refer to the direction toward the exterior of the shoe. 
     For purposes of this disclosure, the foregoing directional terms, when used in reference to an article of footwear, shall refer to the article of footwear when sitting in an upright position, with the sole facing groundward, that is, as it would be positioned when worn by a wearer standing on a substantially level surface. 
     In addition, for purposes of this disclosure, the term “fixedly attached” shall refer to two components joined in a manner such that the components may not be readily separated (for example, without destroying one or both of the components). Exemplary modalities of fixed attachment may include joining with permanent adhesive, rivets, stitches, nails, staples, welding or other thermal bonding, or other joining techniques. In addition, two components may be “fixedly attached” by virtue of being integrally formed, for example, in a molding process. 
     For purposes of this disclosure, the term “removably attached” or “removably inserted” shall refer to the joining of two components or a component and an element in a manner such that the two components are secured together, but may be readily detached from one another. Examples of removable attachment mechanisms may include hook and loop fasteners, friction fit connections, interference fit connections, threaded connectors, cam-locking connectors, compression of one material with another, and other such readily detachable connectors. 
       FIG. 1  illustrates a schematic isometric view of an embodiment of article of footwear  100  that is configured with a tensioning system  150 . In the current embodiment, article of footwear  100 , also referred to hereafter simply as article  100 , is shown in the form of an athletic shoe, such as a running shoe. However, in other embodiments, tensioning system  150  may be used with any other kind of footwear including, but not limited to: hiking boots, soccer shoes, football shoes, sneakers, running shoes, cross-training shoes, rugby shoes, basketball shoes, baseball shoes as well as other kinds of shoes. Moreover, in some embodiments article  100  may be configured for use with various kinds of non-sports related footwear, including, but not limited to: slippers, sandals, high heeled footwear, loafers as well as any other kinds of footwear. As discussed in further detail below, a tensioning system may not be limited to footwear and in other embodiments a tensioning system and/or components associated with a tensioning system could be used with various kinds of apparel, including clothing, sportswear, sporting equipment and other kinds of apparel. In still other embodiments, a tensioning system may be used with braces, such as medical braces. 
     As noted above, for consistency and convenience, directional adjectives are employed throughout this detailed description. Article  100  may be divided into three general regions along a longitudinal axis  180 : a forefoot region  105 , a midfoot region  125 , and a heel region  145 . Forefoot region  105  generally includes portions of article  100  corresponding with the toes and the joints connecting the metatarsals with the phalanges. Midfoot region  125  generally includes portions of article  100  corresponding with an arch area of the foot. Heel region  145  generally corresponds with rear portions of the foot, including the calcaneus bone. Forefoot region  105 , midfoot region  125 , and heel region  145  are not intended to demarcate precise areas of article  100 . Rather, forefoot region  105 , midfoot region  125 , and heel region  145  are intended to represent general relative areas of article  100  to aid in the following discussion. Since various features of article  100  extend beyond one region of article  100 , the terms forefoot region  105 , midfoot region  125 , and heel region  145  apply not only to article  100 , but also to the various features of article  100 . 
     Referring to  FIG. 1 , for reference purposes, a lateral axis  190  of article  100 , and any components related to article  100 , may extend between a medial side  165  and a lateral side  185  of the foot. Additionally, in some embodiments, longitudinal axis  180  may extend from forefoot region  105  to a heel region  145 . It will be understood that each of these directional adjectives may also be applied to individual components of an article of footwear, such as an upper and/or a sole member. In addition, a vertical axis  170  refers to the axis perpendicular to a horizontal surface defined by longitudinal axis  180  and lateral axis  190 . 
     Article  100  may include upper  102  and sole structure  104 . Generally, upper  102  may be any type of upper. In particular, upper  102  may have any design, shape, size and/or color. For example, in embodiments where article  100  is a basketball shoe, upper  102  could be a high top upper that is shaped to provide high support on an ankle. In embodiments where article  100  is a running shoe, upper  102  could be a low top upper. 
     As shown in  FIG. 1 , upper  102  may include one or more material elements (for example, meshes, textiles, foam, leather, and synthetic leather), which may be joined to define an interior void configured to receive a foot of a wearer. The material elements may be selected and arranged to impart properties such as light weight, durability, air-permeability, wear-resistance, flexibility, and comfort. Upper  102  may define an opening  130  through which a foot of a wearer may be received into the interior void. 
     At least a portion of sole structure  104  may be fixedly attached to upper  102  (for example, with adhesive, stitching, welding, or other suitable techniques) and may have a configuration that extends between upper  102  and the ground. Sole structure  104  may include provisions for attenuating ground reaction forces (that is, cushioning and stabilizing the foot during vertical and horizontal loading). In addition, sole structure  104  may be configured to provide traction, impart stability, and control or limit various foot motions, such as pronation, supination, or other motions. 
     In some embodiments, sole structure  104  may be configured to provide traction for article  100 . In addition to providing traction, sole structure  104  may attenuate ground reaction forces when compressed between the foot and the ground during walking, running or other ambulatory activities. The configuration of sole structure  104  may vary significantly in different embodiments to include a variety of conventional or non-conventional structures. In some cases, the configuration of sole structure  104  can be configured according to one or more types of ground surfaces on which sole structure  104  may be used. 
     For example, the disclosed concepts may be applicable to footwear configured for use on any of a variety of surfaces, including indoor surfaces or outdoor surfaces. The configuration of sole structure  104  may vary based on the properties and conditions of the surfaces on which article  100  is anticipated to be used. For example, sole structure  104  may vary depending on whether the surface is harder or softer. In addition, sole structure  104  may be tailored for use in wet or dry conditions. 
     In some embodiments, sole structure  104  may be configured for a particularly specialized surface or condition. The proposed footwear upper construction may be applicable to any kind of footwear, such as basketball, soccer, football, and other athletic activities. Accordingly, in some embodiments, sole structure  104  may be configured to provide traction and stability on hard indoor surfaces (such as hardwood), soft, natural turf surfaces, or on hard, artificial turf surfaces. In some embodiments, sole structure  104  may be configured for use on multiple different surfaces. 
     As will be discussed further below, in different embodiments, sole structure  104  may include different components. For example, sole structure  104  may include an outsole, a midsole, a cushioning layer, and/or an insole. In addition, in some cases, sole structure  104  can include one or more cleat members or traction elements that are configured to increase traction with a ground surface. 
     In some embodiments, sole structure  104  may include multiple components, which may individually or collectively provide article  100  with a number of attributes, such as support, rigidity, flexibility, stability, cushioning, comfort, reduced weight, or other attributes. In some embodiments, sole structure  104  may include an insole/sockliner, a midsole  151 , and a ground-contacting outer sole member (“outsole”)  162 , which may have an exposed, ground-contacting lower surface. In some cases, however, one or more of these components may be omitted. In one embodiment, sole structure  104  may comprise a sole plate, as will be further discussed below. 
     Furthermore, in some embodiments, an insole may be disposed in the void defined by upper  102 . The insole may extend through each of forefoot region  105 , midfoot region  125 , and heel region  145 , and between lateral side  185  and medial side  165  of article  100 . The insole may be formed of a deformable (for example, compressible) material, such as polyurethane foams, or other polymer foam materials. Accordingly, the insole may, by virtue of its compressibility, provide cushioning, and may also conform to the foot in order to provide comfort, support, and stability. 
     Midsole  151  may be fixedly attached to a lower area of upper  102 , for example, through stitching, adhesive bonding, thermal bonding (such as welding), or other techniques, or may be integral with upper  102 . Midsole  151  may be formed from any suitable material having the properties described above, according to the activity for which article  100  is intended. In some embodiments, midsole  151  may include a foamed polymer material, such as polyurethane (PU), ethyl vinyl acetate (EVA), or any other suitable material that operates to attenuate ground reaction forces as sole structure  104  contacts the ground during walking, running, or other ambulatory activities. 
     Midsole  151  may extend through each of forefoot region  105 , midfoot region  125 , and heel region  145 , and between lateral side  185  and medial side  165  of article  100 . In some embodiments, portions of midsole  151  may be exposed around the periphery of article  100 , as shown in  FIG. 1 . In other embodiments, midsole  151  may be completely covered by other elements, such as material layers from upper  102 . For example, in some embodiments, midsole  151  and/or other portions of upper  102  may be disposed adjacent to a bootie (see  FIGS. 3 and 4 ). 
     Furthermore, as shown in  FIG. 1 , article  100  may include a tongue  172 , which may be provided near or along a throat opening  132 . In some embodiments, tongue  172  may be provided in or near an instep region  110  of article  100 . However, in other embodiments, tongue  172  may be disposed along other portions of an article of footwear, or an article may not include a tongue. 
     In addition, as noted above, in different embodiments, article  100  may include a tensioning system  150 . Tensioning system  150  may comprise various components and systems for adjusting the size of an opening  130  leading to an interior void (see  FIG. 2 ) and tightening (or loosening) upper  102  around a wearer&#39;s foot. Some examples of different tensioning systems that can be used are disclosed in Beers et al., U.S. Patent Publication Number 2014/0070042 published Mar. 13, 2014, (previously U.S. patent application Ser. No. 14/014,555, filed Aug. 30, 2013) and entitled “Motorized Tensioning System with Sensors” and Beers et al., U.S. Pat. No. 8,056,269, issued Nov. 15, 2011 (previously U.S. Patent Publication Number 2009/0272013, published Nov. 5, 2009) and entitled “Article of Footwear with Lighting System” the entire disclosures of which are incorporated herein by reference. 
     In some embodiments, tensioning system  150  may comprise one or more laces, as well as a motorized tensioning device. A lace may be configured to pass through various lacing guides  154 , which may be further associated with the edges of a throat opening  132 . In some cases, lacing guides  154  may provide a similar function to traditional eyelets on uppers. In particular, as a lace is pulled or tensioned, throat opening  132  may generally constrict so that upper  102  is tightened around a foot. 
     The arrangement of lacing guides  154  in  FIG. 1  is only intended to be exemplary and it will be understood that other embodiments are not limited to a particular configuration for lacing guides  154 . Furthermore, the particular types of lacing guides  154  illustrated in the embodiments are also exemplary and other embodiments may incorporate any other kinds of lacing guides or similar lacing provisions. In some other embodiments, for example, laces could be inserted through traditional eyelets. Some examples of lace guiding provisions that may be incorporated into the embodiments are disclosed in Cotterman et al., U.S. Patent Application Publication Number 2012/0000091, published Jan. 5, 2012 and entitled “Lace Guide,” the disclosure of which is incorporated herein by reference in its entirety. Additional examples are disclosed in Goodman et al., U.S. Patent Application Publication Number 2011/0266384, published Nov. 3, 2011 and entitled “Reel Based Lacing System”, the disclosure of which is incorporated herein by reference in its entirety. Still additional examples of lace guides are disclosed in Kerns et al., U.S. Patent Application Publication Number 2011/0225843, published Sep. 22, 2011 and entitled “Guides For Lacing Systems,” the disclosure of which is incorporated herein by reference in its entirety. 
     A lace as used with article  100  may comprise any type of type of lacing material known in the art. Examples of laces that may be used include cables or fibers having a low modulus of elasticity as well as a high tensile strength. A lace may comprise a single strand of material, or can comprise multiple strands of material. An exemplary material for the lace is SPECTRA™, manufactured by Honeywell of Morris Township N.J., although other kinds of extended chain, high modulus polyethylene fiber materials can also be used as a lace. Still further exemplary properties of a lace can be found in the Reel Based Lacing Application mentioned above. 
     Thus, in some embodiments, a lace may be passed through lacing guides  154 . In other embodiments, a lace may pass through internal channels  153  within upper  102  after entering channel openings  156  that are near lacing guides  154 . In some embodiments, internal channels  153  extend around the sides of upper  102  and guide the lace towards a motorized tensioning device disposed in sole structure  104 . In some cases, the motorized tensioning device may include provisions for receiving portions of a lace. In some cases, end portions of the lace can exit internal channels  153  of upper  102  and can pass through apertures in a housing unit that contains a motorized tensioning device. 
     In some embodiments, a motorized tensioning device may generally be configured to automatically apply tension to a lace for purposes of tightening and loosening upper  102 . A motorized tensioning device may thus include provisions for winding a lace onto, and unwinding a lace from, a spool internal to the motorized tensioning device. Moreover, the provisions may include an electric motor that automatically winds and unwinds the spool in response to various inputs or controls. 
     Some embodiments may include one or more compartments disposed throughout various portions of article  100 . For purposes of this disclosure, a compartment refers to a separate or distinct section or portion of article  100 . In some embodiments, a compartment can include a sleeve-like region, a tunnel or tubing disposed within article  100 , and/or a recess, cavity, pocket, chamber, slot, pouch, or other space configured to receive an object, element, or component. In some embodiments, during manufacture of article  100 , one or more compartments can be included in article  100 , as will be discussed below. 
     Referring to  FIG. 2 , an isometric side view of article  100  is illustrated with a transparent view to reveal a portion of an interior void  218 .  FIG. 2  includes a depiction of an embodiment of a compartment  202 , disposed within a portion of sole structure  104 . In some embodiments, sole structure  104  can include a sole plate  250 . In some embodiments, midsole  151  may be disposed adjacent to or receive sole plate  250 . In one embodiment, compartment  202  may be formed within sole plate  250 . 
     In some embodiments, a compartment may be designed, dimensioned, or configured to receive different types of components or elements. For example, compartment  202 , which is associated with sole plate  250 , comprises a cavity  275 , and is disposed underneath an optional insole  216  (depicted here with a dotted line). In other words, in different embodiments, article  100  may include different regions configured for the insertion or installation of other objects, elements, or components. 
     Furthermore, it should be understood that the embodiments described herein with respect to compartment  202  in  FIG. 2  may be applicable to articles that do not include a tensioning system. In other words, sole plate  250  may be utilized in any type or configuration of footwear or article of apparel. 
     In order to provide the reader with greater understanding of the proposed embodiments, two views are depicted of sole plate  250  in  FIGS. 3 and 4 . In  FIG. 3 , a front isometric view of an embodiment of sole plate  250  is illustrated, and in  FIG. 4 , a top-down isometric view of an embodiment of sole plate  250  is illustrated. Sole plate  250  can include different regions or sections in some embodiments. As shown in  FIGS. 3-4 , for purposes of reference, sole plate  250  may be divided into a forward portion  302 , an intermediate portion  304 , and a rearward portion  306 . In different embodiments, the shape of sole plate  250  can vary. In one embodiment, the shape of sole plate  250  may resemble a generally oblong shape comprising forward portion  302 , joined to a substantially rectangular shape comprising intermediate portion  304 , which is joined to a substantially oblong shape comprising rearward portion  306 . In other embodiments, the perimeter and shape of different portions of sole plate  250  may vary from what is depicted here, and include any regular or irregular shape. 
     In some embodiments, portions of sole plate  250  may comprise a substantially flat or two-dimensional material or structure. The term “two-dimensional” as used throughout this detailed description and in the claims refers to any generally flat material exhibiting a length and width that are substantially greater than a thickness of the material. Although two-dimensional materials may have smooth or generally untextured surfaces, some two-dimensional materials will exhibit textures or other surface characteristics, such as dimpling, protrusions, ribs, or various patterns, for example. In other embodiments, the geometry of sole plate  250  could vary and could include various contours or features associated with parts of a foot, for example, the sole region of a foot. It should also be understood that in some embodiments, sole plate  250  may be disposed along a midsole in an asymmetrical manner, as shown in  FIGS. 6 and 7  below. 
     Furthermore, in some embodiments, sole plate  250  and other components of sole structure  104  can be formed of various material compositions. In some embodiments, sole plate  250  can be associated with a higher stiffness or hardness than upper  102 . In one embodiment, sole plate  250  is at least partially formed of thermoplastic polyurethane (TPU). In other embodiments, sole plate  250  may comprise a glass-filled nylon material. In still other embodiments, sole plate  250  may comprise a glass-filled TPU. In some embodiments, sole plate  250  may comprise a light-diffusive material, as will be discussed below with respect to  FIG. 13 . 
     In  FIGS. 3-4 , for purposes of reference, a central longitudinal axis  380  and a central lateral axis  390  are depicted superimposed over the illustration of sole plate  250 . It should be understood that central longitudinal axis  380  is arranged to generally bisect sole plate  250  along a midline aligned with longitudinal axis  180 , and central lateral axis  390  is arranged to generally bisect sole plate  250  along a midline aligned with lateral axis  190 . 
     To appreciate the dimensions of sole plate  250 , it can be seen that sole plate  250  has a plate width  310  and a plate length  320 . Plate width  310  extends from a first end  330  associated with medial side  165  of forward portion  302  to a second end  340  associated with lateral side  185  of intermediate portion  304 . Plate length  350  extends from a third end  350  associated with a foremost tip of forward portion  302  to a fourth end  360  associated with a rearmost tip of rearward portion  306 . 
     Plate width  310  can be seen to include or encompass a first width  312 , a second width  314 , and a third width  316 . First width  312  is associated with the maximum width of forward portion  302 , second width  314  is associated with the maximum width of intermediate portion  304 , and third width  316  is associated with the maximum width of rearward portion  306 . In addition, plate length  320  can be seen to include a first length  322 , a second length  324 , and a third length  326 . First length  322  is associated with the maximum length of forward portion  302 , second length  324  is associated with the maximum length of intermediate portion  304 , and third length  326  is associated with the maximum length of rearward portion  306 . 
     As shown in  FIGS. 3 and 4 , in some embodiments, second width  314  may be greater than either first width  312  or third width  316 . Furthermore, first width  312  can be greater than third width  316 . In some embodiments, first length  322  may be greater than either second length  324  or third length  326 . In addition, first length  322  and third length  326  may be substantially dissimilar, while first length  322  and second length  324  may be relatively closer in length. Thus, first length  322  of forward portion  302  may be significantly longer than third length  326  of rearward portion  306  in some embodiments. In different embodiments, the dimensions of sole plate  250  can vary. For example, first length  322  may be less than either second length  324  or third length  326  in some embodiments. In other embodiments, second width  314  may be less than either first width  312  or third width  316 . 
     It can also be noted that in some embodiments, forward portion  302  and rearward portion  306  may be disposed to form varying arrangements relative to intermediate portion  304 . Referring to  FIGS. 3 and 4 , forward portion  302  is arranged such that it is substantially disposed along medial side  165  of sole plate  250 . In addition, rearward portion  306  is arranged such that it is substantially disposed along lateral side  185  of sole plate  250 . In other words, as illustrated in  FIG. 3 , if it is understood that central longitudinal axis  380  represents a longitudinal midline of sole plate  250 , forward portion  302  can be disposed along a first side  382 , and rearward portion  306  can be disposed along a second side  384 . In other words, forward portion  302  and rearward portion  306  may be laterally offset. 
     Furthermore, referring to  FIG. 3 , it can be seen that a forward central longitudinal axis  305  associated with a longitudinal midline of forward portion  302  is disposed along first side  382 , and a rearward central longitudinal axis  309  associated with a longitudinal midline of rearward portion  306  is disposed along second side  384 . In some embodiments, forward central longitudinal axis  305  can extend further from central longitudinal axis  380  toward first side  382  than rearward central longitudinal axis  309  extends from central longitudinal axis  380  toward second side  384 . For example, in  FIG. 3 , forward central longitudinal axis  305  is disposed a first distance  303  from central longitudinal axis  380  along a direction aligned with lateral axis  190 . Furthermore, rearward central longitudinal axis  309  is disposed a second distance  307  from central longitudinal axis  380  along a direction aligned with lateral axis  190 . In some embodiments, first distance  303  may be different than second distance  307 . In the embodiment of  FIG. 3 , first distance  303  is substantially greater than second distance  307 . In other embodiments, second distance  307  may be substantially greater than first distance  303 . Thus, in some embodiments, the separation between the central longitudinal axes associated with forward portion  302  and rearward portion  306  can be greater than the separation of either of the central axes (represented by forward central longitudinal axis  305  and rearward central longitudinal axis  309 ) from central longitudinal axis  380  along a lateral direction. Thus, in  FIG. 3 , a third distance  311  associated with the distance between forward central longitudinal axis  305  and rearward central longitudinal axis  309  in a direction aligned with lateral axis  190  is greater than either first distance  303  or second distance  307 . 
     In some embodiments, the lateral offset arrangement can enhance the torsional rigidity of sole plate  250 . Thus, in some cases, forward portion  302  can provide a stabilizing plate portion within sole plate  250 . Similarly, in other cases, rearward portion  306  may provide a stabilizing plate portion within sole plate  250 . In some embodiments, forward portion  302  and/or rearward portion  306  can increase the stability of sole plate  250  when incorporated into a sole structure. 
     Furthermore, intermediate portion  304  can be disposed to extend between or across both first side  382  and second side  384 . In addition, it can be seen that forward portion  302  may be joined to intermediate portion  304  in a different manner than rearward portion  306 . In  FIG. 4 , while a first border  450  of intermediate portion  304  is joined in a manner that is substantially continuous with a second border  460  of forward portion  302 , a third border  470  of intermediate portion  304  is only partially joined to a fourth border  480  of rearward portion  306 . In other words, rearward portion  306  extends from third border  470  such that a portion of third border  470  remains separate and/or unattached to any additional sole plate portion. However, forward portion  302  has been arranged such that first border  450  flows or merges in a substantially contiguous manner with second border  460 , and first border  450  and second border  460  form a common border. It should be understood by the reader that the labels applied herein (such as first border  450 , second border  460 , third border  470 , fourth border  480 ) are for illustrate purposes only and do not necessarily demarcate specific regions of sole plate  250 . 
     Thus, in different embodiments, different portions of sole plate  250  may be asymmetrical with respect to one another, relative to a central axis. For purposes of this description, the term “asymmetrical” and “asymmetric” are used to characterize regions of a sole component or articles. As used herein, two regions of a sole component have a symmetric configuration when the regions have a symmetry about some common axis. In contrast, two regions of a sole component have an asymmetric configuration when there is no axis about which the sole members have a symmetry. It may be further understood that the characterizations of symmetric and asymmetric may be with reference to all features of the sole component, or with reference to only some subset of features. In particular, given a feature of a sole component, two or more regions of the sole component may be considered as symmetric or asymmetric only with respect to that feature. In the following embodiments, for example, specific consideration is given of the asymmetry of the various portions of sole plate  250  with respect to a particular axis. It should further be understood that while a sole component may generally include some level of asymmetry, the asymmetry described herein may be primarily directed to any asymmetry in the position and/or orientation of the arrangement of portions of sole plate  250  (in particular, of forward portion  302  and rearward portion  306 ). 
     Furthermore, referring to  FIG. 4 , there may be differences in the overall size of forward portion  302  relative to rearward portion  306 . For example, forward portion  302  may comprise a first area  410 , and rearward portion  306  may comprise a second area  420 . In different embodiments, first area  410  may differ from second area  420 . In some embodiments, the area associated with first area  410  may be larger than the area associated with second area  420 . In  FIG. 4 , first area  410  is significantly larger in area than second area  420 . Thus, forward portion  302  may be understood to comprise a greater proportion of sole plate  250  than rearward portion  306  in some embodiments. However, it should be understood that in other embodiments, first area  410  and second area  420  may be substantially similar, or second area  420  may be larger in area than first area  410 . 
     In addition, as shown in  FIG. 4 , there may be differences in the curvature or geometry of forward portion  302  relative to rearward portion  306 . For purposes of this disclosure, the curvature associated with a component or portion represents the degree to which its geometry along an axis deviates from a straight line. In  FIG. 4 , the overall curvature of forward portion  302  that extends in a direction generally aligned with longitudinal axis  180  is identified by a first curved axis  430 . Similarly, the overall curvature of rearward portion  306  that extends in a direction generally aligned with longitudinal axis  180  is identified by a second curved axis  440 . In some embodiments, first curved axis  430  may differ from second curved axis  440 . 
     In some embodiments, for example, the degree of curvature associated with first curved axis  430  may be larger than second curved axis  440 . In  FIG. 4 , first curved axis  430  has a substantially greater degree of curvature than second curved axis  440 . Thus, forward portion  302  may be understood to comprise a less regular or linear region than rearward portion  306  in some embodiments. In other words, rearward portion  306  may be more linear relative to the arrangement of forward portion  302 . However, it should be understood that in other embodiments, first curved axis  430  and second curved axis  440  may be substantially similar, or second curved axis  440  may have a greater curvature than first curved axis  430 . 
     Furthermore, as shown in  FIG. 4 , forward portion  302  may be arranged such that it extends beyond the maximum width (i.e., second width  314 ) of intermediate portion  304  along medial side  165 . In other words, while intermediate portion  304  can extend a first distance  490  toward medial side  165 , forward portion  302  can extend a second distance  492  towards medial side  165 . In some embodiments, second distance  492  may be greater than first distance  490 . Thus, forward portion  302  may be disposed to extend further toward medial side  165  from central longitudinal axis  380  than intermediate portion  304  in one embodiment. 
     In some embodiments, rearward portion  306  may be arranged such that it extends less than the maximum width (i.e., second width  314 ) of intermediate portion  304  along lateral side  185 . In some cases, rearward portion  306  may be disposed more centrally relative to forward portion  302 . For example, in  FIG. 4 , intermediate portion  304  extends a third distance  494  toward lateral side  185 , while rearward portion  306  extends a fourth distance  496  toward lateral side  185 . In other words, while both intermediate portion  304  and rearward portion  306  are at least partially disposed along lateral side  185 , intermediate portion  304  may extend further toward lateral side  185  relative to central longitudinal axis  380 . Thus, in some embodiments, third distance  494  can be greater than fourth distance  496 . 
     However, it should be understood that in other embodiments, first distance  490  and second distance  492  may be substantially similar, or first distance  490  may be greater than second distance  492 . Similarly, in some embodiments, third distance  494  and fourth distance  496  may be substantially similar, or third distance  494  may be less than fourth distance  496 . It should further be understood by the reader that the labels applied herein (such as first distance  490 , second distance  492 , third distance  494 , fourth distance  496 ) are for illustrate purposes only and do not necessarily demarcate specific dimensions of sole plate  250 . 
     Referring now to  FIG. 5 , a side isometric view of an embodiment of sole plate  250  is depicted. As noted earlier with respect to  FIG. 2 , sole plate  250  includes a compartment  202 . Compartment  202  includes a cavity  275  defined by a series of sidewalls and a base. In  FIG. 5 , cavity  275  comprises a first sidewall  502 , a second sidewall  504 , a third sidewall  506 , and a fourth sidewall  508 , as well as a base portion  510 . In different embodiments, the dimensions and/or shape associated with the regions of cavity  275  can vary with respect to each other. In some embodiments, first sidewall  502  can include an upper length  512  and a lower length  514 . Furthermore, second sidewall  504  can include an upper width  516  and a lower width  518 . In some embodiments, upper length  512  may be different from upper width  516 . In one embodiment, upper length  512  is greater than upper width  516 , as shown in  FIG. 5 . However, in other embodiments, upper length  512  may be substantially similar or less than upper width  516 . In some embodiments, the dimensions of third sidewall  506  may be substantially similar to the dimensions of first sidewall  502 . Similarly, in some embodiments, the dimensions of fourth sidewall  508  may be substantially similar to the dimensions of second sidewall  504 . However, in other embodiments, the dimensions of each sidewall may differ from one another. 
     Furthermore, in one embodiment, first sidewall  502  and/or third sidewall  506  can generally extend along a direction aligned with lateral axis  190 . In another embodiment, fourth sidewall  508  and/or second sidewall  504  can generally extend along a direction aligned with longitudinal axis  180 . As a result, in some cases, cavity  275  may include a substantially rectangular prism shape, where sidewalls that lie along a similar axis (i.e., sidewalls that are substantially parallel) are also generally matched in shape and size. However, in other embodiments, the perimeter and shape of different portions of cavity  275  may vary from what is depicted here, and include any regular or irregular shape, including three-dimensional rectangular, square, elliptical, oval, round shapes. 
     In different embodiments, the orientation of each sidewall may differ from one another, such that cavity  275  has a less regular three-dimensional shape. For example, the edges of one or more sidewalls may extend in a diagonal direction. In  FIG. 5 , a first edge  524  of first sidewall  502  is oriented at a first angle  532  relative to vertical axis  170 , and a second edge  526  of first sidewall  502  is oriented at a second angle  534  relative to vertical axis  170 . In some embodiments, first angle  532  and/or second angle  534  may be acute angles. In other embodiments, first angle  532  and/or second angle  534  may be obtuse angles. In one embodiment, first angle  532  and/or second angle  534  may be right angles. 
     Thus, in some embodiments, cavity  275  may comprise a substantially quadrilateral frustum (apex-truncated square pyramid) shaped recess. In other embodiments, cavity  275  may be a substantially three-dimensional rectangular shape, where one side remains open. More simply, base portion  510  may have a first area  520 , and an opening  536  leading into cavity  275  bounded by the upper edges of the sidewalls may have a second area  522 , and first area  520  and second area  522  may differ. In one embodiment, first area  520  may be less than second area  522 , such that the adjoining edges of sidewalls taper inward toward a center of the cavity. In another embodiment, first area  520  may be greater than second area, such that the adjoining edges of sidewalls extend outward toward the perimeter of intermediate portion  304 . This shape can improve the fit of intermediate portion  304  within a midsole or other sole component in some embodiments. In addition, the shape associated with cavity  275  can be configured to snugly receive, accommodate, and/or better secure a specific component (such as motorized tensioning device  160  in  FIG. 1 ) in one embodiment. 
     Furthermore, in some embodiments, there may be triangular or pyramidal portions disposed along one or more regions of cavity  275 . For example, in  FIG. 5 , first sidewall  502  includes a forward triangular portion  538  and a rear triangular portion  540 . Triangular portions may also be included along other sidewalls, such as along opposing third sidewall  506 . The geometry of the triangular portions can increase the stability of intermediate portion  304 , as well as of sole plate  250 . In addition, the triangular portions can act to provide better grip when sole plate  250  is placed on a surface. The triangular portions can also be configured for an improved fit within midsole  151  (see  FIGS. 6 and 7 ). 
     Compartment  202  may also include provisions for holding or securing a component in different embodiments. For example, along base portion  510  of cavity  275  there may be one or more ridges  542 . Ridges  542  may form an uneven or undulating surface along at least one side of base portion  510 . The use of ridges  542  can increase grip between base portion  510  and a surface of a component in some embodiments. In some cases, ridges  542  may be substantially parallel with respect to one another. In one embodiment, ridges  542  may be oriented along a direction aligned with lateral axis  190 . 
     In addition, sole plate  250  may include provisions for improved contact with other components of article  100  (see FIG. 2 ), and increased stability of sole plate  250  when assembled within sole structure  104 . For example, adjacent to opening  536  of cavity  275 , compartment  202  includes a first flange  546  and a second flange  548 . First flange  546  is disposed to extend generally upward at a diagonal angle from first sidewall  502 , and second flange  548  is disposed to extend generally upward at a diagonal angle from third sidewall  506 . Thus, first flange  546  is disposed along lateral side  185  of sole plate  250 , and second flange  548  is disposed along medial side  165  of sole plate  250 . When sole plate  250  is assembled in an article of footware, first flange  546  can create a smooth, continuous surface that extends between cavity  275  and lateral side  185 . Similarly, when sole plate  250  is assembled in an article of footware, second flange  548  can create a smooth, continuous surface that extends between cavity  275  and medial side  165 . This can also increase comfort for a user when a foot is disposed in interior void  218  (see FIG. 2 ). Furthermore, each flange can be substantially similar in size and geometry to another flange, or be different. For example, first flange  546  can be larger in surface area than second flange  548  in one embodiment. Thus, first flange  546  and second flange  548  may be asymmetric with respect to one another in some embodiments. However, in other embodiments, first flange  546  and second flange  548  may be substantially similar. 
     In different embodiments, sole plate  250  may be assembled, incorporated, joined, or otherwise disposed adjacent to an additional component of article  100 .  FIGS. 6-8  provide an example of the joining between two components including sole plate  250  and midsole  151 .  FIG. 6  depicts a top-down view of an embodiment of sole plate  250  and midsole  151 .  FIG. 7  depicts a top-down view of an embodiment of the receipt of sole plate  250  by midsole  151 , forming combined sole layers  700 . In  FIG. 8 , a bottom isometric perspective of sole structure  104  is illustrated, providing a view of a portion of the bottom surface of sole plate  250 . 
     Referring now to  FIG. 6 , for purposes of reference, midsole  151  may be divided into a first portion  602 , a bridge portion  604 , and a second portion  606 . In different embodiments, the shape of midsole  151  can vary. In one embodiment, the shape of midsole  151  may resemble a generally elliptical or oval shape along first portion  602  and a generally oblong rectangular shape comprising second portion  606 , where first portion  602  and second portion  606  are joined along a substantially rectangular shaped bridge portion  604 . Bridge portion  604  may be narrow relative to either first portion  602  or second portion  606 . In other embodiments, the perimeter and shape of different portions of midsole  151  may vary from what is depicted here, and include any regular or irregular shape. 
     It can be seen that in some embodiments, sole plate  250  may be generally smaller in size than midsole  151 . For example, while sole plate  250  has plate length  320 , midsole  151  has a midsole length  620  that is greater than plate length  320 . In addition, plate width  310  is smaller than a midsole width  610  associated with a maximum width of midsole  151 . Furthermore, a plate area  650  associated with the area of an inner surface side  651  of sole plate  250  may be significantly less than a midsole area  652  associated with the area of an inner surface side  653  of midsole  151 , where the inner surface sides represent the side of each sole component that would face a foot when an article including the various sole components is worn. Thus, in some embodiments, midsole  151  may be large enough to receive or accommodate at least a portion of sole plate  250 . Furthermore, midsole  151  may include a border panel  685  disposed around the perimeter of midsole  151  that is raised with respect to inner surface side  653 . In some cases, midsole  151  (and in particular border panel  685 ) may form a recessed portion that can be configured to receive or snugly accommodate sole plate  250  or another component. 
     However, in other embodiments, the relative dimensions of midsole  151  and sole plate  250  may differ from those illustrated here. For example, midsole length  620  may be substantially similar to or less than plate length  320 , and midsole width  610  may be substantially similar to or less than plate width  310  in different embodiments. Furthermore, midsole area  652  may be substantially similar to or less than plate area  650  in other embodiments. 
     In  FIG. 6 , for purposes of reference, a first central longitudinal axis  680  is depicted superimposed over the illustration of midsole  151 . Similarly, a second central longitudinal axis  780  is depicted superimposed over the illustration of combined sole layers  700  in  FIG. 7 . Furthermore, in  FIG. 8 , a third central longitudinal axis  880  is depicted superimposed over the illustration of an assembled sole structure. It should be understood that first central longitudinal axis  680  is arranged to generally bisect midsole  151  along a midline aligned with longitudinal axis  180 , second central longitudinal axis  780  is arranged to generally bisect combined sole layers  700  along a midline aligned with longitudinal axis  180 , and third central longitudinal axis  880  is arranged to generally bisect the assembled sole structure along a midline aligned with longitudinal axis  180 . 
     Referring specifically to bridge portion  604  in  FIG. 6 , it may be noted that relative to first longitudinal axis  680 , bridge portion  604  can be disposed further toward one side versus another side. In other words, bridge portion  604  is arranged such that it is disposed along medial side  165  of midsole  151 . In other words, if it is understood that first central longitudinal axis  680  represents a longitudinal midline of midsole  151 , bridge portion  604  can be disposed along a first side  682 . In other embodiments, bridge portion  604  may be disposed along a second side  684 . In other words, bridge portion  604  may be laterally offset with respect to first central longitudinal axis  680 . In another embodiment, bridge portion  604  may be disposed more centrally and/or encompass both first side  682  and second side  684 . 
     As a result of the shape and size of bridge portion  604 , two open regions may be disposed adjacent to bridge portion  604 . In  FIG. 6 , a first region  632  and a second region  634  are shown. First region  632  is defined by a segment of a perimeter edge of first portion  602  that extends toward lateral side  185 , a first edge  636  of bridge portion  604 , and a segment of a perimeter edge of second portion  606  that extends toward lateral side  185 . In addition, second region  634  is defined by a segment of the perimeter edge of first portion  602  that extends toward medial side  165 , a second edge  638  of bridge portion  604 , and a segment of the perimeter edge of second portion  606  that extends toward medial side  165 . In some embodiments, first region  632  may encompass a larger area than second region  634 . For example, in  FIG. 6 , first region  632  can have a first area and second region  634  can have a second area, where the size of first area is greater than the size of second area. However, in other embodiments, the size of first area may be substantially similar to or less than the size of second area. 
     When sole plate  250  is disposed or deposited within the recess formed in midsole  151  (i.e., within the boundary formed by border panel  685 ), as shown in  FIG. 7 , the configuration of sole plate  250  as discussed in  FIGS. 3-4  can be asymmetrically disposed in midsole  151 . In some embodiments, for example, forward portion  302  may be arranged further toward first side  682  relative to second central longitudinal axis  780 . Furthermore, intermediate portion  304  may be positioned such that it is generally central and is disposed along both first side  682  and second side  684 . In addition, rearward portion  306  may be positioned such that it is disposed further toward second side  684  relative to second central longitudinal axis  730 . In other words, forward portion  302  and rearward portion  306  can be laterally offset with respect to one another when assembled within midsole  151 . 
     As shown in  FIG. 8 , the configuration of midsole  151  can also allow portions of the underside of sole plate  250  to remain exposed in the assembled state. For purposes of this disclosure, the underside of sole plate  250  refers to the bottom-facing and/or outward-facing surfaces of sole plate  250  that forms an opposing surface to inner surface side  651  (shown in  FIG. 6 ). Furthermore, the assembled state refers to the state in which the entire sole structure (which can comprise at least sole plate  250  and midsole  151 ) has been assembled and is ready for use, installation, and/or integration with an upper for an article of footwear. 
     In  FIG. 8 , an isometric bottom view of an embodiment of an assembled sole structure is shown. The sole structure includes outsole  162  joined to midsole  151 , where midsole  151  is joined to or is disposed adjacent to sole plate  250 . In different embodiments, outsole  162  may include a shape and size substantially similar to that of at least a portion of midsole  151 . For example, in  FIG. 8 , it can be seen that outsole  162  covers a large portion of midsole  151 . In other embodiments, outsole  162  may comprise a different shape or size. In one embodiment, outsole  162  may cover a smaller portion of midsole  151  than depicted here. In another embodiment, outsole  162  may cover substantially all of the outer surface side (not shown) of midsole  151 , where the outer surface side represents the opposing surface of inner surface side  653  (see  FIGS. 6 and 7 ). In other embodiments, outsole  162  may be substantially larger than midsole  151 . 
     In addition, in some embodiments, as noted earlier, sole plate  250  may be at least partially exposed in the assembled sole structure. Referring to  FIG. 8 , an underside  800  of sole plate  250  is depicted. Underside  800  can include one or more exposed regions. In  FIG. 8 , sole plate  250  includes two exposed regions, here referred to as a third region  830  and a fourth region  840 . In some embodiments, third region  830  can include both a portion of base portion  510  and a portion of first sidewall  502  (identified in  FIG. 5 ). Similarly, in some embodiments, fourth region  840  can include both a portion of base portion  510  and a portion of third sidewall  506  (shown in  FIG. 5 ). 
     In different embodiments, third region  830  can correspond with first region  632  of midsole  151 , and fourth region  840  can correspond with second region  634  of midsole  151 . In other words, third region  830  may be defined by the boundary that also surrounds and defines first region  632 , and fourth region  840  may be defined by the boundary that also surrounds and defines second region  634 . Furthermore, in some embodiments, third region  830  may encompass or comprise a larger area than fourth region  840 . For example, in  FIG. 8 , third region  830  has a third area  833  and fourth region  840  has a fourth area  835 , where third area  833  is greater than fourth area  835 . In other words, third region  830  and fourth region  840  may be asymmetric with respect to their degree of exposure. Thus, base portion  510  is asymmetrically exposed, where medial side  165  of base portion  510  is less exposed or is smaller in size than lateral side  185  of base portion  510 . However, it should be understood that in other embodiments, third area  833  may be substantially similar to or less than fourth area  835 . For example, medial side  165  of base portion  510  can be more exposed or be larger in size than lateral side  185  of base portion  510  in some embodiments. 
     Thus, the arrangement of exposed regions of sole plate  250  may vary. For example, fourth region  840  is arranged such that it is disposed along medial side  165  of the assembled sole structure. In addition, third region  830  is arranged such that it is substantially disposed toward lateral side  185  of the assembled sole structure, though a smaller proportion of third region  830  can also extend into medial side  165 . In other words, if it is understood that third central longitudinal axis  880  represents a longitudinal midline of the assembled sole structure, fourth region  840  can be disposed along a first side  882  and third region  830  can be disposed primarily along a second side  884 . 
     Referring now to  FIG. 9 , an embodiment of article  100  is shown. To provide reader with a view of sole plate  250  while sole plate  250  is disposed within article  100 , upper  102  is shown in dotted line, and the optional insole is removed to reveal a portion of sole plate  250 . In  FIG. 9 , a component  900  is also illustrated adjacent to article  100 . As noted above, one or more components may be installed in article  100 . In different embodiments, installation of components may occur after the initial manufacture of article  100 , and may be facilitated by the formation of one or more compartments in article  100 . 
     In one embodiment, one or more components may be configured to provide various functions or features to article  100 . For example, in  FIG. 9 , component  900  comprises a housing unit containing motorized tensioning device  160 . In other embodiments, different mechanical or electrical components may be included, such as circuitry, textiles, or other materials. As noted above, article  100  may be manufactured to accommodate one or more components in a manner that can allows the ready and secure incorporation of components post-manufacture. In other words, article  100  may include one or more compartments for receiving a component. In the embodiment illustrated in  FIG. 9 , article  100  may be manufactured such that compartment  202  is configured to receive component  900 . 
     In some embodiments, the housing unit of component  900  may include various mechanisms or elements that can be utilized in tensioning system  150  (see  FIG. 1 ). For example, within the interior of component  900  there may be a battery (or other power source), circuitry (or other control mechanism), spools, gears, a motor, light sources, and/or other mechanisms. However, in other embodiments, the housing unit may have different dimensions and/or shapes. In  FIG. 9 , component  900  has a substantially three-dimensional rectangular shape. 
     As noted above, compartment  202  may comprise cavity  275  in sole plate  250 . Cavity  275  may be bounded by one or more sidewalls that form a region with an average depth  910  in sole plate  250 . In some embodiments, the dimensions of cavity  275  may be designed or configured for secure and/or snug receipt of the housing unit of component  900 . In  FIG. 9 , cavity  275  includes depth  910  greater than a thickness  920  of housing unit of component  900 . Furthermore, a first area  930  associated with a first side  902  of component  900  may be less than a second area  932  associated with base portion  510  of cavity  275 . In other words, cavity  275  may be dimensioned to at least partially encompass or hold component  900 . In some embodiments, for example, second area  932  may be slightly larger than first area  930 , such that a substantially snug fit is formed between component  900  and compartment  202 . However, in other embodiments, dimensions of either component  900  or compartment  202  may differ such that one is substantially different from the other. 
     Thus, in some embodiments, component  900  may be easily deposited or inserted into cavity  275  of sole plate  250  without requiring the removal of sole plate  250  from article  100 . In other embodiments, however, it may be desirable to remove sole plate  250  before installation of component  900 . 
     In different embodiments, sole plate  250  may include provisions for better engaging with and/or securing component  900 . In  FIG. 10 , an isolated view of cavity  275  is illustrated. As described with respect to  FIG. 5 , cavity  275  includes first sidewall  502 , second sidewall  504 , third sidewall  506 , fourth sidewall  508 , base portion  510 , and opening  536 . Referring to a magnified view  1050 , it can be seen that third sidewall  506  includes two tabs protruding from third sidewall  506 , disposed near a third edge  1060 . The two tabs may be identified herein as a first tab  1010  and a second tab  1020 . First tab  1010  and second tab  1020  are arranged along a direction aligned with a fourth central longitudinal axis  1080 . Furthermore, each tab extends inward toward the center of cavity  275 . 
     First tab  1010  and second tab  1020  may each comprise substantially similar lengths and sizes in some embodiments, as shown in  FIG. 10 . However, in other embodiments, the lengths and/or sizes of tabs may differ with respect to one another. Furthermore, there may be a fewer number or a greater number of tabs in other embodiments. In addition, tabs may be disposed along other regions of cavity  275  in different embodiments. For example, in another embodiment, first tab  1010  may be disposed along first sidewall  502 , second sidewall  504 , and/or fourth sidewall  508 . 
     First tab  1010  and/or second tab  1020  may include one or more slots  1030  in some embodiments. Slots  1030  may be formed along the surface of first tab  1010  and/or second tab  1020 . In one embodiment, slots  1030  may extend from the surface of third sidewall  506  toward a free end  1040  of the tabs. Each tab may include a plurality of slots  1030 . In some embodiments, slots  1030  may be arranged around the outer surface of first tab  1010 . In  FIG. 10 , slots  1030  may be spaced apart from their neighboring slot on the same tab by substantially similar distances. In other embodiments, slots  1030  may be disposed at irregular intervals along a tab. 
     In different embodiments, first tab  1010  and second tab  1020  may provide a mechanism for retaining a component in the interior of cavity  275 . For example, referring now to  FIG. 11 , once component  900  is disposed within compartment  202 , it may remain somewhat moveable. In some embodiments, component  900  may remain less fixedly disposed in order to facilitate a later removal of component  900  and/or reinsertion of component  900  if desired. In order to improve the securement of component  900  within cavity  275 , first tab  1010  and/or second tab  1020  can be used to hold, retain, press, or otherwise steady component  900  within cavity  275  in some embodiments. Thus, in one embodiment, opening  536  remains sufficiently unobstructed for the insertion of component  900  along one side. However, once it is slid completely into cavity  275 , it can remain relatively secure as a result of the inclusion of one or more tabs in some embodiments. In one embodiment, tabs can help the component resist exiting or being pushed from cavity  275 . 
     In different embodiments, first tab  1010  and/or second tab  1020  may be associated with medial side  165  of sole plate  250 , which can be advantageous in embodiments where, for example, wiring  1100  or lacing (or other elements) extending from component  900  exit from cavity  275  via medial side  165 . In other embodiments, tabs may be located within sole plate  250  in a manner configured to suit the type of component and/or connection pathway of an article. 
     In other embodiments, it should be understood that additional materials or components may be included or inserted into sole structure  104 . In one embodiment, to enhance the impact strength of sole plate  250 , there may be a portion of rubber or dampening material adhered to one surface or portion of sole plate  250 , for example. In other embodiments, insulating material or other filler or cushioning material may be deposited around component  900  during installation of component  900 . 
     Referring now to  FIG. 12 , article  100  is illustrated with component  900  installed. In  FIG. 12 , upper  102  and sole structure  104  are depicted in solid line, while component  900  and sole plate  250  are depicted in dotted lines, to provide a view of interior void  218 . It can be seen that component  900  is disposed in compartment  202  within sole plate  250 . 
     In other embodiments, any component could be disposed in any other portions of an article, including the upper and/or sole structure. In some cases, some components could be disposed in one portion of an article and other components could be disposed in another, different, portion. In another embodiment, for example, component  900  comprising the housing unit with a motorized tensioning device could be disposed near heel region  145  of sole plate  250  in article  100 . The location of one or more components may be selected according to various factors including, but not limited to: size constraints, manufacturing constraints, aesthetic preferences, optimal design and functional placement, ease of removability or accessibility relative to other portions of article  100 , as well as possibly other factors. 
     Once components have been installed in article  100 , various systems may be operated or used by a wearer. For example, referring to  FIG. 13 , tensioning system  150  may include a housing unit and/or any of the features and components that have been described above. In one embodiment, when the system associated with article  100  is activated or utilized, a signal may be transmitted to activate an LED unit that can be disposed in the component (for example, component  900  described above with respect to  FIG. 9 ). During use by a wearer  1350  of article  100 , LED lights associated with the component can turn on and off. 
     In different embodiments, some regions of article  100  may be configured for providing optimal use of various components. In one example, sole plate  250 —specifically the region of sole plate  250  associated with compartment  202  (particularly exposed third region  830  and/or fourth region  840  as shown in  FIG. 8 ) may include light-diffusive, light-transmissive, translucent, and/or transparent materials. Such materials can facilitate the transmission of light from an LED (or other light source) that has been incorporated into cavity  275  or other portions of article  100  during or after manufacture of article  100 . 
     Referring to  FIG. 13 , the material comprising cavity  275  may be formed of a light-diffusive material, for example. Thus, component  900  comprising an LED unit may emit light that can be visible to the wearer or others via the diffuse material of sole plate  250 . In some embodiments, an enhanced aesthetic design may be produced by the use of various diffusive materials with an LED unit, providing the wearer with a light diffuser effect. For example, in  FIG. 13 , in a first view  1310 , article  100  is shown in an “LED off” state. However, as shown in a second view  1320 , article  100  may transition to an “LED on” state, where one or more lights located within cavity  275  of sole plate  250  may turn on. In one embodiment, light can be emitted through the material comprising cavity  275  in the “LED on” state. This is illustrated in second view  1320  of  FIG. 13 , where light is being diffused through third region  830  (labeled in  FIG. 8 ) of sole plate  250 .
