Patent Description:
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. <CIT> describes a sensor system adapted for use with an article of footwear and includes an insert member including a first layer and a second layer, a port connected to the insert and configured for communication with an electronic module, a plurality of force and/or compression sensors on the insert member, and a plurality of leads connecting the sensors to the port.

A sole structure for an article of footwear according to the claimed invention is defined in claim <NUM>. Dependent claims <NUM> to <NUM> define advantageous embodiments of the sole structure according to the claimed invention. 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.

Other systems, methods, features and advantages of the embodiments will be, or will become, apparent to one of ordinary skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description and this summary.

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. 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's foot when the shoes 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> illustrates a schematic isometric view of an embodiment of article of footwear <NUM> that is configured with a tensioning system <NUM>. In the current embodiment, article of footwear <NUM>, also referred to hereafter simply as article <NUM>, is shown in the form of an athletic shoe, such as a running shoe. However, in other embodiments, tensioning system <NUM> 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 <NUM> 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 <NUM> may be divided into three general regions along a longitudinal axis <NUM>: a forefoot region <NUM>, a midfoot region <NUM>, and a heel region <NUM>. Forefoot region <NUM> generally includes portions of article <NUM> corresponding with the toes and the joints connecting the metatarsals with the phalanges. Midfoot region <NUM> generally includes portions of article <NUM> corresponding with an arch area of the foot. Heel region <NUM> generally corresponds with rear portions of the foot, including the calcaneus bone. Forefoot region <NUM>, midfoot region <NUM>, and heel region <NUM> are not intended to demarcate precise areas of article <NUM>. Rather, forefoot region <NUM>, midfoot region <NUM>, and heel region <NUM> are intended to represent general relative areas of article <NUM> to aid in the following discussion. Since various features of article <NUM> extend beyond one region of article <NUM>, the terms forefoot region <NUM>, midfoot region <NUM>, and heel region <NUM> apply not only to article <NUM>, but also to the various features of article <NUM>.

Referring to <FIG>, for reference purposes, a lateral axis <NUM> of article <NUM>, and any components related to article <NUM>, may extend between a medial side <NUM> and a lateral side <NUM> of the foot. Additionally, in some embodiments, longitudinal axis <NUM> may extend from forefoot region <NUM> to a heel region <NUM>. 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 <NUM> refers to the axis perpendicular to a horizontal surface defined by longitudinal axis <NUM> and lateral axis <NUM>.

Article <NUM> may include upper <NUM> and sole structure <NUM>. Generally, upper <NUM> may be any type of upper. In particular, upper <NUM> may have any design, shape, size and/or color. For example, in embodiments where article <NUM> is a basketball shoe, upper <NUM> could be a high top upper that is shaped to provide high support on an ankle. In embodiments where article <NUM> is a running shoe, upper <NUM> could be a low top upper.

As shown in <FIG>, upper <NUM> 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 <NUM> may define an opening <NUM> through which a foot of a wearer may be received into the interior void.

At least a portion of sole structure <NUM> may be fixedly attached to upper <NUM> (for example, with adhesive, stitching, welding, or other suitable techniques) and may have a configuration that extends between upper <NUM> and the ground. Sole structure <NUM> may include provisions for attenuating ground reaction forces (that is, cushioning and stabilizing the foot during vertical and horizontal loading). In addition, sole structure <NUM> 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 <NUM> may be configured to provide traction for article <NUM>. In addition to providing traction, sole structure <NUM> 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 <NUM> may vary significantly in different embodiments to include a variety of conventional or non-conventional structures. In some cases, the configuration of sole structure <NUM> can be configured according to one or more types of ground surfaces on which sole structure <NUM> 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 <NUM> may vary based on the properties and conditions of the surfaces on which article <NUM> is anticipated to be used. For example, sole structure <NUM> may vary depending on whether the surface is harder or softer. In addition, sole structure <NUM> may be tailored for use in wet or dry conditions.

In some embodiments, sole structure <NUM> 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 <NUM> 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 <NUM> may be configured for use on multiple different surfaces.

As will be discussed further below, in different embodiments, sole structure <NUM> may include different components. A sole structure <NUM> according to the claimed invention includes a midsole, and may further include an outsole a cushioning layer, and/or an insole. In addition, in some cases, sole structure <NUM> 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 <NUM> may include multiple components, which may individually or collectively provide article <NUM> with a number of attributes, such as support, rigidity, flexibility, stability, cushioning, comfort, reduced weight, or other attributes. In some embodiments, sole structure <NUM> may include an insole/socklirier, a midsole <NUM>, and a ground-contacting outer sole member ("outsole") <NUM>, which may have an exposed, ground-contacting lower surface. In some cases, however, one or more of these components may be omitted. According to the claimed invention, sole structure <NUM> comprises a sole plate, as will be further discussed below.

Furthermore, in some embodiments, an insole may be disposed in the void defined by upper <NUM>. The insole may extend through each of forefoot region <NUM>, midfoot region <NUM>, and heel region <NUM>, and between lateral side <NUM> and medial side <NUM> of article <NUM>. 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 <NUM> may be fixedly attached to a lower area of upper <NUM>, for example, through stitching, adhesive bonding, thermal bonding (such as welding), or other techniques, or may be integral with upper <NUM>. Midsole <NUM> may be formed from any suitable material having the properties described above, according to the activity for which article <NUM> is intended. In some embodiments, midsole <NUM> 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 <NUM> contacts the ground during walking, running, or other ambulatory activities.

Midsole <NUM> may extend through each of forefoot region <NUM>, midfoot region <NUM>, and heel region <NUM>, and between lateral side <NUM> and medial side <NUM> of article <NUM>. In some embodiments, portions of midsole <NUM> may be exposed around the periphery of article <NUM>, as shown in <FIG>. In other embodiments, midsole <NUM> may be completely covered by other elements, such as material layers from upper <NUM>. For example, in some embodiments, midsole <NUM> and/or other portions of upper <NUM> may be disposed adjacent to a bootie (see <FIG> and <FIG>).

Furthermore, as shown in <FIG>, article <NUM> may include a tongue <NUM>, which may be provided near or along a throat opening <NUM>. In some embodiments, tongue <NUM> may be provided in or near an instep region <NUM> of article <NUM>. However, in other embodiments, tongue <NUM> 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 <NUM> may include a tensioning system <NUM>. Tensioning system <NUM> may comprise various components and systems for adjusting the size of an opening <NUM> leading to an interior void (see <FIG>) and tightening (or loosening) upper <NUM> around a wearer's foot. Some examples of different tensioning systems that can be used are disclosed in <CIT>, (previously <CIT>, <CIT> (previously <CIT>) and entitled "Article of Footwear with Lighting System".

In some embodiments, tensioning system <NUM> may comprise one or more laces, as well as a motorized tensioning device. A lace may be configured to pass through various lacing guides <NUM>, which may be further associated with the edges of a throat opening <NUM>. In some cases, lacing guides <NUM> may provide a similar function to traditional eyelets on uppers. In particular, as a lace is pulled or tensioned, throat opening <NUM> may generally constrict so that upper <NUM> is tightened around a foot.

The arrangement of lacing guides <NUM> in <FIG> is only intended to be exemplary and it will be understood that other embodiments are not limited to a particular configuration for lacing guides <NUM>. Furthermore, the particular types of lacing guides <NUM> 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 <CIT> and entitled "Lace Guide,". Additional examples are disclosed in<CIT> and entitled "Reel Based Lacing System". Still additional examples of lace guides are disclosed in <CIT> and entitled "Guides For Lacing Systems,".

A lace as used with article <NUM> 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 NJ, 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 <NUM>. In other embodiments, a lace may pass through internal channels <NUM> within upper <NUM> after entering channel openings <NUM> that are near lacing guides <NUM>. In some embodiments, internal channels <NUM> extend around the sides of upper <NUM> and guide the lace towards a motorized tensioning device disposed in sole structure <NUM>. 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 <NUM> of upper <NUM> 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 <NUM>. 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 <NUM>. For purposes of this disclosure, a compartment refers to a separate or distinct section or portion of article <NUM>. In some embodiments, a compartment can include a sleeve-like region, a tunnel or tubing disposed within article <NUM>, 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 <NUM>, one or more compartments can be included in article <NUM>, as will be discussed below.

Referring to <FIG>, an isometric side view of article <NUM> is illustrated with a transparent view to reveal a portion of an interior void <NUM>. <FIG> includes a depiction of an embodiment of a compartment <NUM>, disposed within a portion of sole structure <NUM>. According to the claimed invention, sole structure <NUM> includes a sole plate <NUM>. In some embodiments, midsole <NUM> may be disposed adjacent to or receive sole plate <NUM>. In one embodiment, compartment <NUM> may be formed within sole plate <NUM>.

In some embodiments, a compartment may be designed, dimensioned, or configured to receive different types of components or elements. For example, compartment <NUM>, which is associated with sole plate <NUM>, comprises a cavity <NUM>, and is disposed underneath an optional insole <NUM> (depicted here with a dotted line). In other words, in different embodiments, article <NUM> 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 <NUM> in <FIG> may be applicable to articles that do not include a tensioning system. In other words, sole plate <NUM> 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 <NUM> in <FIG> and <FIG>. In <FIG>, a front isometric view of an embodiment of sole plate <NUM> is illustrated, and in <FIG>, a top-down isometric view of an embodiment of sole plate <NUM> is illustrated. Sole plate <NUM> can include different regions or sections in some embodiments. As shown in <FIG>, for purposes of reference, sole plate <NUM> may be divided into a forward portion <NUM>, an intermediate portion <NUM>, and a rearward portion <NUM>. In different embodiments, the shape of sole plate <NUM> can vary. In one embodiment, the shape of sole plate <NUM> may resemble a generally oblong shape comprising forward portion <NUM>, joined to a substantially rectangular shape comprising intermediate portion <NUM>, which is joined to a substantially oblong shape comprising rearward portion <NUM>. In other embodiments, the perimeter and shape of different portions of sole plate <NUM> may vary from what is depicted here, and include any regular or irregular shape.

In some embodiments, portions of sole plate <NUM> 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 <NUM> 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 <NUM> may be disposed along a midsole in an asymmetrical manner, as shown in <FIG> below.

Furthermore, in some embodiments, sole plate <NUM> and other components of sole structure <NUM> can be formed of various material compositions. In some embodiments, sole plate <NUM> can be associated with a higher stiffness or hardness than upper <NUM>. In one embodiment, sole plate <NUM> is at least partially formed of thermoplastic polyurethane (TPU). In other embodiments, sole plate <NUM> may comprise a glass-filled nylon material. In still other embodiments, sole plate <NUM> may comprise a glass-filled TPU. In some embodiments, sole plate <NUM> may comprise a light-diffusive material, as will be discussed below with respect to <FIG>.

In <FIG>, for purposes of reference, a central longitudinal axis <NUM> and a central lateral axis <NUM> are depicted superimposed over the illustration of sole plate <NUM>. It should be understood that central longitudinal axis <NUM> is arranged to generally bisect sole plate <NUM> along a midline aligned with longitudinal axis <NUM>, and central lateral axis <NUM> is arranged to generally bisect sole plate <NUM> along a midline aligned with lateral axis <NUM>.

To appreciate the dimensions of sole plate <NUM>, it can be seen that sole plate <NUM> has a plate width <NUM> and a plate length <NUM>. Plate width <NUM> extends from a first end <NUM> associated with medial side <NUM> of forward portion <NUM> to a second end <NUM> associated with lateral side <NUM> of intermediate portion <NUM>. Plate length <NUM> extends from a third end <NUM> associated with a foremost tip of forward portion <NUM> to a fourth end <NUM> associated with a rearmost tip of rearward portion <NUM>.

Plate width <NUM> can be seen to include or encompass a first width <NUM>, a second width <NUM>, and a third width <NUM>. First width <NUM> is associated with the maximum width of forward portion <NUM>, second width <NUM> is associated with the maximum width of intermediate portion <NUM>, and third width <NUM> is associated with the maximum width of rearward portion <NUM>. In addition, plate length <NUM> can be seen to include a first length <NUM>, a second length <NUM>, and a third length <NUM>. First length <NUM> is associated with the maximum length of forward portion <NUM>, second length <NUM> is associated with the maximum length of intermediate portion <NUM>, and third length <NUM> is associated with the maximum length of rearward portion <NUM>.

As shown in <FIG> and <FIG>, in some embodiments, second width <NUM> may be greater than either first width <NUM> or third width <NUM>. Furthermore, first width <NUM> can be greater than third width <NUM>. In some embodiments, first length <NUM> may be greater than either second length <NUM> or third length <NUM>. In addition, first length <NUM> and third length <NUM> may be substantially dissimilar, while first length <NUM> and second length <NUM> may be relatively closer in length. Thus, first length <NUM> of forward portion <NUM> may be significantly longer than third length <NUM> of rearward portion <NUM> in some embodiments. In different embodiments, the dimensions of sole plate <NUM> can vary. For example, first length <NUM> may be less than either second length <NUM> or third length <NUM> in some embodiments. In other embodiments, second width <NUM> may be less than either first width <NUM> or third width <NUM>.

It can also be noted that in some embodiments, forward portion <NUM> and rearward portion <NUM> may be disposed to form varying arrangements relative to intermediate portion <NUM>. Referring to <FIG> and <FIG>, forward portion <NUM> is arranged such that it is substantially disposed along medial side <NUM> of sole plate <NUM>. In addition, rearward portion <NUM> is arranged such that it is substantially disposed along lateral side <NUM> of sole plate <NUM>. In other words, as illustrated in <FIG>, if it is understood that central longitudinal axis <NUM> represents a longitudinal midline of sole plate <NUM>, forward portion <NUM> can be disposed along a first side <NUM>, and rearward portion <NUM> can be disposed along a second side <NUM>. In other words, forward portion <NUM> and rearward portion <NUM> may be laterally offset.

Furthermore, referring to <FIG>, it can be seen that a forward central longitudinal axis <NUM> associated with a longitudinal midline of forward portion <NUM> is disposed along first side <NUM>, and a rearward central longitudinal axis <NUM> associated with a longitudinal midline of rearward portion <NUM> is disposed along second side <NUM>. In some embodiments, forward central longitudinal axis <NUM> can extend further from central longitudinal axis <NUM> toward first side <NUM> than rearward central longitudinal axis <NUM> extends from central longitudinal axis <NUM> toward second side <NUM>. For example, in <FIG>, forward central longitudinal axis <NUM> is disposed a first distance <NUM> from central longitudinal axis <NUM> along a direction aligned with lateral axis <NUM>. Furthermore, rearward central longitudinal axis <NUM> is disposed a second distance <NUM> from central longitudinal axis <NUM> along a direction aligned with lateral axis <NUM>. In some embodiments, first distance <NUM> may be different than second distance <NUM>. In the embodiment of <FIG>, first distance <NUM> is substantially greater than second distance <NUM>. In other embodiments, second distance <NUM> may be substantially greater than first distance <NUM>. Thus, in some embodiments, the separation between the central longitudinal axes associated with forward portion <NUM> and rearward portion <NUM> can be greater than the separation of either of the central axes (represented by forward central longitudinal axis <NUM> and rearward central longitudinal axis <NUM>) from central longitudinal axis <NUM> along a lateral direction. Thus, in <FIG>, a third distance <NUM> associated with the distance between forward central longitudinal axis <NUM> and rearward central longitudinal axis <NUM> in a direction aligned with lateral axis <NUM> is greater than either first distance <NUM> or second distance <NUM>.

In some embodiments, the lateral offset arrangement can enhance the torsional rigidity of sole plate <NUM>. Thus, in some cases, forward portion <NUM> can provide a stabilizing plate portion within sole plate <NUM>. Similarly, in other cases, rearward portion <NUM> may provide a stabilizing plate portion within sole plate <NUM>. In some embodiments, forward portion <NUM> and/or rearward portion <NUM> can increase the stability of sole plate <NUM> when incorporated into a sole structure.

Furthermore, intermediate portion <NUM> can be disposed to extend between or across both first side <NUM> and second side <NUM>. In addition, it can be seen that forward portion <NUM> may be joined to intermediate portion <NUM> in a different manner than rearward portion <NUM>. In <FIG>, while a first border <NUM> of intermediate portion <NUM> is joined in a manner that is substantially continuous with a second border <NUM> of forward portion <NUM>, a third border <NUM> of intermediate portion <NUM> is only partially joined to a fourth border <NUM> of rearward portion <NUM>. In other words, rearward portion <NUM> extends from third border <NUM> such that a portion of third border <NUM> remains separate and/or unattached to any additional sole plate portion. However, forward portion <NUM> has been arranged such that first border <NUM> flows or merges in a substantially contiguous manner with second border <NUM>, and first border <NUM> and second border <NUM> form a common border. It should be understood by the reader that the labels applied herein (such as first border <NUM>, second border <NUM>, third border <NUM>, fourth border <NUM>) are for illustrate purposes only and do not necessarily demarcate specific regions of sole plate <NUM>.

Thus, in different embodiments, different portions of sole plate <NUM> 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 <NUM> 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 <NUM> (in particular, of forward portion <NUM> and rearward portion <NUM>).

Furthermore, referring to <FIG>, there may be differences in the overall size of forward portion <NUM> relative to rearward portion <NUM>. For example, forward portion <NUM> may comprise a first area <NUM>, and rearward portion <NUM> may comprise a second area <NUM>. In different embodiments, first area <NUM> may differ from second area <NUM>. In some embodiments, the area associated with first area <NUM> may be larger than the area associated with second area <NUM>. In <FIG>, first area <NUM> is significantly larger in area than second area <NUM>. Thus, forward portion <NUM> may be understood to comprise a greater proportion of sole plate <NUM> than rearward portion <NUM> in some embodiments. However, it should be understood that in other embodiments, first area <NUM> and second area <NUM> may be substantially similar, or second area <NUM> may be larger in area than first area <NUM>.

In addition, as shown in <FIG>, there may be differences in the curvature or geometry of forward portion <NUM> relative to rearward portion <NUM>. 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>, the overall curvature of forward portion <NUM> that extends in a direction generally aligned with longitudinal axis <NUM> is identified by a first curved axis <NUM>. Similarly, the overall curvature of rearward portion <NUM> that extends in a direction generally aligned with longitudinal axis <NUM> is identified by a second curved axis <NUM>. In some embodiments, first curved axis <NUM> may differ from second curved axis <NUM>.

In some embodiments, for example, the degree of curvature associated with first curved axis <NUM> may be larger than second curved axis <NUM>. In <FIG>, first curved axis <NUM> has a substantially greater degree of curvature than second curved axis <NUM>. Thus, forward portion <NUM> may be understood to comprise a less regular or linear region than rearward portion <NUM> in some embodiments. In other words, rearward portion <NUM> may be more linear relative to the arrangement of forward portion <NUM>. However, it should be understood that in other embodiments, first curved axis <NUM> and second curved axis <NUM> may be substantially similar, or second curved axis <NUM> may have a greater curvature than first curved axis <NUM>.

Furthermore, as shown in <FIG>, forward portion <NUM> may be arranged such that it extends beyond the maximum width (i.e., second width <NUM>) of intermediate portion <NUM> along medial side <NUM>. In other words, while intermediate portion <NUM> can extend a first distance <NUM> toward medial side <NUM>, forward portion <NUM> can extend a second distance <NUM> towards medial side <NUM>. In some embodiments, second distance <NUM> may be greater than first distance <NUM>. Thus, forward portion <NUM> may be disposed to extend further toward medial side <NUM> from central longitudinal axis <NUM> than intermediate portion <NUM> in one embodiment.

In some embodiments, rearward portion <NUM> may be arranged such that it extends less than the maximum width (i.e., second width <NUM>) of intermediate portion <NUM> along lateral side <NUM>. In some cases, rearward portion <NUM> may be disposed more centrally relative to forward portion <NUM>. For example, in <FIG>, intermediate portion <NUM> extends a third distance <NUM> toward lateral side <NUM>, while rearward portion <NUM> extends a fourth distance <NUM> toward lateral side <NUM>. In other words, while both intermediate portion <NUM> and rearward portion <NUM> are at least partially disposed along lateral side <NUM>, intermediate portion <NUM> may extend further toward lateral side <NUM> relative to central longitudinal axis <NUM>. Thus, in some embodiments, third distance <NUM> can be greater than fourth distance <NUM>.

However, it should be understood that in other embodiments, first distance <NUM> and second distance <NUM> may be substantially similar, or first distance <NUM> may be greater than second distance <NUM>. Similarly, in some embodiments, third distance <NUM> and fourth distance <NUM> may be substantially similar, or third distance <NUM> may be less than fourth distance <NUM>. It should further be understood by the reader that the labels applied herein (such as first distance <NUM>, second distance <NUM>, third distance <NUM>, fourth distance <NUM>) are for illustrate purposes only and do not necessarily demarcate specific dimensions of sole plate <NUM>.

Referring now to <FIG>, a side isometric view of an embodiment of sole plate <NUM> is depicted. As noted earlier with respect to <FIG> and according to the claimed invention, sole plate <NUM> includes a compartment <NUM>. Compartment <NUM> includes a cavity <NUM> defined by a series of sidewalls and a base. In <FIG>, cavity <NUM> comprises a first sidewall <NUM>, a second sidewall <NUM>, a third sidewall <NUM>, and a fourth sidewall <NUM>, as well as a base portion <NUM>. In different embodiments, the dimensions and/or shape associated with the regions of cavity <NUM> can vary with respect to each other. In some embodiments, first sidewall <NUM> can include an upper length <NUM> and a lower length <NUM>. Furthermore, second sidewall <NUM> can include an upper width <NUM> and a lower width <NUM>. In some embodiments, upper length <NUM> may be different from upper width <NUM>. In one embodiment, upper length <NUM> is greater than upper width <NUM>, as shown in <FIG>. However, in other embodiments, upper length <NUM> may be substantially similar or less than upper width <NUM>. In some embodiments, the dimensions of third sidewall <NUM> may be substantially similar to the dimensions of first sidewall <NUM>. Similarly, in some embodiments, the dimensions of fourth sidewall <NUM> may be substantially similar to the dimensions of second sidewall <NUM>. However, in other embodiments, the dimensions of each sidewall may differ from one another.

Furthermore, in one embodiment, first sidewall <NUM> and/or third sidewall <NUM> can generally extend along a direction aligned with lateral axis <NUM>. In another embodiment, fourth sidewall <NUM> and/or second sidewall <NUM> can generally extend along a direction aligned with longitudinal axis <NUM>. As a result, in some cases, cavity <NUM> 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 <NUM> 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 <NUM> has a less regular three-dimensional shape. For example, the edges of one or more sidewalls may extend in a diagonal direction. In <FIG>, a first edge <NUM> of first sidewall <NUM> is oriented at a first angle <NUM> relative to vertical axis <NUM>, and a second edge <NUM> of first sidewall <NUM> is oriented at a second angle <NUM> relative to vertical axis <NUM>. In some embodiments, first angle <NUM> and/or second angle <NUM> may be acute angles. In other embodiments, first angle <NUM> and/or second angle <NUM> may be obtuse angles. In one embodiment, first angle <NUM> and/or second angle <NUM> may be right angles.

Thus, in some embodiments, cavity <NUM> may comprise a substantially quadrilateral frustum (apex-truncated square pyramid) shaped recess. In other embodiments, cavity <NUM> may be a substantially three-dimensional rectangular shape, where one side remains open. More simply, base portion <NUM> may have a first area <NUM>, and an opening <NUM> leading into cavity <NUM> bounded by the upper edges of the sidewalls may have a second area <NUM>, and first area <NUM> and second area <NUM> may differ. In one embodiment, first area <NUM> may be less than second area <NUM>, such that the adjoining edges of sidewalls taper inward toward a center of the cavity. In another embodiment, first area <NUM> may be greater than second area, such that the adjoining edges of sidewalls extend outward toward the perimeter of intermediate portion <NUM>. This shape can improve the fit of intermediate portion <NUM> within a midsole or other sole component in some embodiments. In addition, the shape associated with cavity <NUM> can be configured to snugly receive, accommodate, and/or better secure a specific component (such as motorized tensioning device <NUM> in <FIG>) in one embodiment.

Furthermore, in some embodiments, there may be triangular or pyramidal portions disposed along one or more regions of cavity <NUM>. For example, in <FIG>, first sidewall <NUM> includes a forward triangular portion <NUM> and a rear triangular portion <NUM>. Triangular portions may also be included along other sidewalls, such as along opposing third sidewall <NUM>. The geometry of the triangular portions can increase the stability of intermediate portion <NUM>, as well as of sole plate <NUM>. In addition, the triangular portions can act to provide better grip when sole plate <NUM> is placed on a surface. The triangular portions can also be configured for an improved fit within midsole <NUM> (see <FIG>).

Compartment <NUM> may also include provisions for holding or securing a component in different embodiments. For example, along base portion <NUM> of cavity <NUM> there may be one or more ridges <NUM>. Ridges <NUM> may form an uneven or undulating surface along at least one side of base portion <NUM>. The use of ridges <NUM> can increase grip between base portion <NUM> and a surface of a component in some embodiments. In some cases, ridges <NUM> may be substantially parallel with respect to one another. In one embodiment, ridges <NUM> may be oriented along a direction aligned with lateral axis <NUM>.

In addition, sole plate <NUM> may include provisions for improved contact with other components of article <NUM> (see <FIG>), and increased stability of sole plate <NUM> when assembled within sole structure <NUM>. For example, adjacent to opening <NUM> of cavity <NUM>, compartment <NUM> includes a first flange <NUM> and a second flange <NUM>. First flange <NUM> is disposed to extend generally upward at a diagonal angle from first sidewall <NUM>, and second flange <NUM> is disposed to extend generally upward at a diagonal angle from third sidewall <NUM>. Thus, first flange <NUM> is disposed along lateral side <NUM> of sole plate <NUM>, and second flange <NUM> is disposed along medial side <NUM> of sole plate <NUM>. When sole plate <NUM> is assembled in an article of footwear, first flange <NUM> can create a smooth, continuous surface that extends between cavity <NUM> and lateral side <NUM>. Similarly, when sole plate <NUM> is assembled in an article of footwear, second flange <NUM> can create a smooth, continuous surface that extends between cavity <NUM> and medial side <NUM>. This can also increase comfort for a user when a foot is disposed in interior void <NUM> (see <FIG>). Furthermore, each flange can be substantially similar in size and geometry to another flange, or be different. For example, first flange <NUM> can be larger in surface area than second flange <NUM> in one embodiment. Thus, first flange <NUM> and second flange <NUM> may be asymmetric with respect to one another in some embodiments. However, in other embodiments, first flange <NUM> and second flange <NUM> may be substantially similar.

In different embodiments, sole plate <NUM> may be assembled, incorporated, joined, or otherwise disposed adjacent to an additional component of article <NUM>. <FIG> provide an example of the joining between two components including sole plate <NUM> and midsole <NUM>. <FIG> depicts a top-down view of an embodiment of sole plate <NUM> and midsole <NUM>. <FIG> depicts a top-down view of an embodiment of the receipt of sole plate <NUM> by midsole <NUM>, forming combined sole layers <NUM>. In <FIG>, a bottom isometric perspective of sole structure <NUM> is illustrated, providing a view of a portion of the bottom surface of sole plate <NUM>.

Referring now to <FIG>, for purposes of reference, midsole <NUM> may be divided into a first portion <NUM>, a bridge portion <NUM>, and a second portion <NUM>. In different embodiments, the shape of midsole <NUM> can vary. In one embodiment, the shape of midsole <NUM> may resemble a generally elliptical or oval shape along first portion <NUM> and a generally oblong rectangular shape comprising second portion <NUM>, where first portion <NUM> and second portion <NUM> are joined along a substantially rectangular shaped bridge portion <NUM>. Bridge portion <NUM> may be narrow relative to either first portion <NUM> or second portion <NUM>. In other embodiments, the perimeter and shape of different portions of midsole <NUM> may vary from what is depicted here, and include any regular or irregular shape.

It can be seen that in some embodiments, sole plate <NUM> may be generally smaller in size than midsole <NUM>. For example, while sole plate <NUM> has plate length <NUM>, midsole <NUM> has a midsole length <NUM> that is greater than plate length <NUM>. In addition, plate width <NUM> is smaller than a midsole width <NUM> associated with a maximum width of midsole <NUM>. Furthermore, a plate area <NUM> associated with the area of an inner surface side <NUM> of sole plate <NUM> may be significantly less than a midsole area <NUM> associated with the area of an inner surface side <NUM> of midsole <NUM>, 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 <NUM> may be large enough to receive or accommodate at least a portion of sole plate <NUM>. Furthermore, midsole <NUM> may include a border panel <NUM> disposed around the perimeter of midsole <NUM> that is raised with respect to inner surface side <NUM>. In some cases, midsole <NUM> (and in particular border panel <NUM>) may form a recessed portion that can be configured to receive or snugly accommodate sole plate <NUM> or another component.

However, in other embodiments, the relative dimensions of midsole <NUM> and sole plate <NUM> may differ from those illustrated here. For example, midsole length <NUM> may be substantially similar to or less than plate length <NUM>, and midsole width <NUM> may be substantially similar to or less than plate width <NUM> in different embodiments. Furthermore, midsole area <NUM> may be substantially similar to or less than plate area <NUM> in other embodiments.

In <FIG>, for purposes of reference, a first central longitudinal axis <NUM> is depicted superimposed over the illustration of midsole <NUM>. Similarly, a second central longitudinal axis <NUM> is depicted superimposed over the illustration of combined sole layers <NUM> in <FIG>. Furthermore, in <FIG>, a third central longitudinal axis <NUM> is depicted superimposed over the illustration of an assembled sole structure. It should be understood that first central longitudinal axis <NUM> is arranged to generally bisect midsole <NUM> along a midline aligned with longitudinal axis <NUM>, second central longitudinal axis <NUM> is arranged to generally bisect combined sole layers <NUM> along a midline aligned with longitudinal axis <NUM>, and third central longitudinal axis <NUM> is arranged to generally bisect the assembled sole structure along a midline aligned with longitudinal axis <NUM>.

Referring specifically to bridge portion <NUM> in <FIG>, it may be noted that relative to first longitudinal axis <NUM>, bridge portion <NUM> can be disposed further toward one side versus another side. In other words, bridge portion <NUM> is arranged such that it is disposed along medial side <NUM> of midsole <NUM>. In other words, if it is understood that first central longitudinal axis <NUM> represents a longitudinal midline of midsole <NUM>, bridge portion <NUM> can be disposed along a first side <NUM>. In other embodiments, bridge portion <NUM> may be disposed along a second side <NUM>. In other words, bridge portion <NUM> may be laterally offset with respect to first central longitudinal axis <NUM>. In another embodiment, bridge portion <NUM> may be disposed more centrally and/or encompass both first side <NUM> and second side <NUM>.

As a result of the shape and size of bridge portion <NUM>, two open regions are disposed adjacent to bridge portion <NUM>. In <FIG>, a first region <NUM> and a second region <NUM> are shown. First region <NUM> is defined by a segment of a perimeter edge of first portion <NUM> that extends toward lateral side <NUM>, a first edge <NUM> of bridge portion <NUM>, and a segment of a perimeter edge of second portion <NUM> that extends toward lateral side <NUM>. In addition, second region <NUM> is defined by a segment of the perimeter edge of first portion <NUM> that extends toward medial side <NUM>, a second edge <NUM> of bridge portion <NUM>, and a segment of the perimeter edge of second portion <NUM> that extends toward medial side <NUM>. In some embodiments, first region <NUM> may encompass a larger area than second region <NUM>. For example, in <FIG>, first region <NUM> can have a first area and second region <NUM> 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 less than the size of second area. In examples not according to the claimed invention, the size of the first area may be substantially similar to the size of the second area.

When sole plate <NUM> is disposed or deposited within the recess formed in midsole <NUM> (i.e., within the boundary formed by border panel <NUM>), as shown in <FIG>, the configuration of sole plate <NUM> as discussed in <FIG> can be asymmetrically disposed in midsole <NUM>. In some embodiments, for example, forward portion <NUM> may be arranged further toward first side <NUM> relative to second central longitudinal axis <NUM>. Furthermore, intermediate portion <NUM> may be positioned such that it is generally central and is disposed along both first side <NUM> and second side <NUM>. In addition, rearward portion <NUM> may be positioned such that it is disposed further toward second side <NUM> relative to second central longitudinal axis <NUM>. In other words, forward portion <NUM> and rearward portion <NUM> can be laterally offset with respect to one another when assembled within midsole <NUM>.

As shown in <FIG>, the configuration of midsole <NUM> allows portions of the underside of sole plate <NUM> to remain exposed in the assembled state. For purposes of this disclosure, the underside of sole plate <NUM> refers to the bottom-facing and/or outward-facing surfaces of sole plate <NUM> that forms an opposing surface to inner surface side <NUM> (shown in <FIG>). Furthermore, the assembled state refers to the state in which the entire sole structure which comprises at least sole plate <NUM> and midsole <NUM>) has been assembled and is ready for use, installation, and/or integration with an upper for an article of footwear.

In <FIG>, an isometric bottom view of an embodiment of an assembled sole structure is shown. The sole structure includes outsole <NUM> joined to midsole <NUM>, where midsole <NUM> is joined to or is disposed adjacent to sole plate <NUM>. In different embodiments, outsole <NUM> may include a shape and size substantially similar to that of at least a portion of midsole <NUM>. For example, in <FIG>, it can be seen that outsole <NUM> covers a large portion of midsole <NUM>. In other embodiments, outsole <NUM> may comprise a different shape or size. In one embodiment, outsole <NUM> may cover a smaller portion of midsole <NUM> than depicted here. In another embodiment, outsole <NUM> may cover substantially all of the outer surface side (not shown) of midsole <NUM>, where the outer surface side represents the opposing surface of inner surface side <NUM> (see <FIG>). In other embodiments, outsole <NUM> may be substantially larger than midsole <NUM>.

In addition, according to the claimed invention, as noted earlier, sole plate <NUM> is at least partially exposed in the assembled sole structure. Referring to <FIG>, an underside <NUM> of sole plate <NUM> is depicted. Underside <NUM> includes two or more exposed regions. In <FIG>, sole plate <NUM> includes two exposed regions, here referred to as a third region <NUM> and a fourth region <NUM>. In some embodiments, third region <NUM> can include both a portion of base portion <NUM> and a portion of first sidewall <NUM> (identified in <FIG>). Similarly, in some embodiments, fourth region <NUM> can include both a portion of base portion <NUM> and a portion of third sidewall <NUM> (shown in <FIG>).

In different embodiments, third region <NUM> can correspond with first region <NUM> of midsole <NUM>, and fourth region <NUM> can correspond with second region <NUM> of midsole <NUM>. In other words, third region <NUM> may be defined by the boundary that also surrounds and defines first region <NUM>, and fourth region <NUM> may be defined by the boundary that also surrounds and defines second region <NUM>. Furthermore, in some embodiments, third region <NUM> may encompass or comprise a larger area than fourth region <NUM>. For example, in <FIG>, third region <NUM> has a third area <NUM> and fourth region <NUM> has a fourth area <NUM>, where third area <NUM> is greater than fourth area <NUM>. In other words, third region <NUM> and fourth region <NUM> may be asymmetric with respect to their degree of exposure. Thus, base portion <NUM> is asymmetrically exposed, where medial side <NUM> of base portion <NUM> is less exposed or is smaller in size than lateral side <NUM> of base portion <NUM>. However, it should be understood that in other embodiments, third area <NUM> may be less than fourth area <NUM>. For example, medial side <NUM> of base portion <NUM> can be more exposed or be larger in size than lateral side <NUM> of base portion <NUM> in some embodiments. In examples not according to the claimed invention, third area may be substantially similar to fourth area.

Thus, the arrangement of exposed regions of sole plate <NUM> may vary. For example, fourth region <NUM> is arranged such that it is disposed along medial side <NUM> of the assembled sole structure. In addition, third region <NUM> is arranged such that it is substantially disposed toward lateral side <NUM> of the assembled sole structure, though a smaller proportion of third region <NUM> can also extend into medial side <NUM>. In other words, if it is understood that third central longitudinal axis <NUM> represents a longitudinal midline of the assembled sole structure, fourth region <NUM> can be disposed along a first side <NUM> and third region <NUM> can be disposed primarily along a second side <NUM>.

Referring now to <FIG>, an embodiment of article <NUM> is shown. To provide reader with a view of sole plate <NUM> while sole plate <NUM> is disposed within article <NUM>, upper <NUM> is shown in dotted line, and the optional insole is removed to reveal a portion of sole plate <NUM>. In <FIG>, a component <NUM> is also illustrated adjacent to article <NUM>. As noted above, one or more components may be installed in article <NUM>. In different embodiments, installation of components may occur after the initial manufacture of article <NUM>, and may be facilitated by the formation of one or more compartments in article <NUM>.

In one embodiment, one or more components may be configured to provide various functions or features to article <NUM>. For example, in <FIG>, component <NUM> comprises a housing unit containing motorized tensioning device <NUM>. In other embodiments, different mechanical or electrical components may be included, such as circuitry, textiles, or other materials. As noted above, article <NUM> 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 <NUM> may include one or more compartments for receiving a component. In the embodiment illustrated in <FIG>, article <NUM> may be manufactured such that compartment <NUM> is configured to receive component <NUM>.

In some embodiments, the housing unit of component <NUM> may include various mechanisms or elements that can be utilized in tensioning system <NUM> (see <FIG>). For example, within the interior of component <NUM> 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>, component <NUM> has a substantially three-dimensional rectangular shape.

According to the claimed invention, compartment <NUM> comprises cavity <NUM> in sole plate <NUM>. Cavity <NUM> may be bounded by one or more sidewalls that form a region with an average depth <NUM> in sole plate <NUM>. In some embodiments, the dimensions of cavity <NUM> may be designed or configured for secure and/or snug receipt of the housing unit of component <NUM>. In <FIG>, cavity <NUM> includes depth <NUM> greater than a thickness <NUM> of housing unit of component <NUM>. Furthermore, a first area <NUM> associated with a first side <NUM> of component <NUM> may be less than a second area <NUM> associated with base portion <NUM> of cavity <NUM>. In other words, cavity <NUM> may be dimensioned to at least partially encompass or hold component <NUM>. In some embodiments, for example, second area <NUM> may be slightly larger than first area <NUM>, such that a substantially snug fit is formed between component <NUM> and compartment <NUM>. However, in other embodiments, dimensions of either component <NUM> or compartment <NUM> may differ such that one is substantially different from the other.

Thus, in some embodiments, component <NUM> may be easily deposited or inserted into cavity <NUM> of sole plate <NUM> without requiring the removal of sole plate <NUM> from article <NUM>. In other embodiments, however, it may be desirable to remove sole plate <NUM> before installation of component <NUM>.

In different embodiments, sole plate <NUM> may include provisions for better engaging with and/or securing component <NUM>. In <FIG>, an isolated view of cavity <NUM> is illustrated. As described with respect to <FIG>, cavity <NUM> includes first sidewall <NUM>, second sidewall <NUM>, third sidewall <NUM>, fourth sidewall <NUM>, base portion <NUM>, and opening <NUM>. Referring to a magnified view <NUM>, it can be seen that third sidewall <NUM> includes two tabs protruding from third sidewall <NUM>, disposed near a third edge <NUM>. The two tabs may be identified herein as a first tab <NUM> and a second tab <NUM>. First tab <NUM> and second tab <NUM> are arranged along a direction aligned with a fourth central longitudinal axis <NUM>. Furthermore, each tab extends inward toward the center of cavity <NUM>.

First tab <NUM> and second tab <NUM> may each comprise substantially similar lengths and sizes in some embodiments, as shown in <FIG>. 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 <NUM> in different embodiments. For example, in another embodiment, first tab <NUM> may be disposed along first sidewall <NUM>, second sidewall <NUM>, and/or fourth sidewall <NUM>.

First tab <NUM> and/or second tab <NUM> may include one or more slots <NUM> in some embodiments. Slots <NUM> may be formed along the surface of first tab <NUM> and/or second tab <NUM>. In one embodiment, slots <NUM> may extend from the surface of third sidewall <NUM> toward a free end <NUM> of the tabs. Each tab may include a plurality of slots <NUM>. In some embodiments, slots <NUM> may be arranged around the outer surface of first tab <NUM>. In <FIG>, slots <NUM> may be spaced apart from their neighboring slot on the same tab by substantially similar distances. In other embodiments, slots <NUM> may be disposed at irregular intervals along a tab.

In different embodiments, first tab <NUM> and second tab <NUM> may provide a mechanism for retaining a component in the interior of cavity <NUM>. For example, referring now to <FIG>, once component <NUM> is disposed within compartment <NUM>, it may remain somewhat moveable. In some embodiments, component <NUM> may remain less fixedly disposed in order to facilitate a later removal of component <NUM> and/or reinsertion of component <NUM> if desired. In order to improve the securement of component <NUM> within cavity <NUM>, first tab <NUM> and/or second tab <NUM> can be used to hold, retain, press, or otherwise steady component <NUM> within cavity <NUM> in some embodiments. Thus, in one embodiment, opening <NUM> remains sufficiently unobstructed for the insertion of component <NUM> along one side. However, once it is slid completely into cavity <NUM>, 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 <NUM>.

In different embodiments, first tab <NUM> and/or second tab <NUM> may be associated with medial side <NUM> of sole plate <NUM>, which can be advantageous in embodiments where, for example, wiring <NUM> or lacing (or other elements) extending from component <NUM> exit from cavity <NUM> via medial side <NUM>. In other embodiments, tabs may be located within sole plate <NUM> 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 <NUM>. In one embodiment, to enhance the impact strength of sole plate <NUM>, there may be a portion of rubber or dampening material adhered to one surface or portion of sole plate <NUM>, for example. In other embodiments, insulating material or other filler or cushioning material may be deposited around component <NUM> during installation of component <NUM>.

Referring now to <FIG>, article <NUM> is illustrated with component <NUM> installed. In <FIG>, upper <NUM> and sole structure <NUM> are depicted in solid line, while component <NUM> and sole plate <NUM> are depicted in dotted lines, to provide a view of interior void <NUM>. It can be seen that component <NUM> is disposed in compartment <NUM> within sole plate <NUM>.

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 <NUM> comprising the housing unit with a motorized tensioning device could be disposed near heel region <NUM> of sole plate <NUM> in article <NUM>. 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 <NUM>, as well as possibly other factors.

Once components have been installed in article <NUM>, various systems may be operated or used by a wearer. For example, referring to <FIG>, tensioning system <NUM> 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 <NUM> is activated or utilized, a signal may be transmitted to activate an LED unit that can be disposed in the component (for example, component <NUM> described above with respect to <FIG>). During use by a wearer <NUM> of article <NUM>, LED lights associated with the component can turn on and off.

In different embodiments, some regions of article <NUM> may be configured for providing optimal use of various components. In one example, sole plate <NUM> - specifically the region of sole plate <NUM> associated with compartment <NUM> (particularly exposed third region <NUM> and/or fourth region <NUM> as shown in <FIG>) 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 <NUM> or other portions of article <NUM> during or after manufacture of article <NUM>.

Referring to <FIG>, the material comprising cavity <NUM> may be formed of a light-diffusive material, for example. Thus, component <NUM> comprising an LED unit may emit light that can be visible to the wearer or others via the diffuse material of sole plate <NUM>. 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>, in a first view <NUM>, article <NUM> is shown in an "LED off" state. However, as shown in a second view <NUM>, article <NUM> may transition to an "LED on" state, where one or more lights located within cavity <NUM> of sole plate <NUM> may turn on. In one embodiment, light can be emitted through the material comprising cavity <NUM> in the "LED on" state. This is illustrated in second view <NUM> of <FIG>, where light is being diffused through third region <NUM> (labeled in <FIG>) of sole plate <NUM>.

Furthermore, the embodiments described herein may also include or refer to techniques, concepts, features, elements, methods, and/or components from <CIT>, titled "An Article of Footwear and a Method of Assembly of the Article of Footwear," (currently Attorney Docket No. <NUM>-<NUM>), <CIT>, titled "A Lockout Feature for a Control Device," (currently Attorney Docket No. <NUM>-<NUM>), <CIT>, titled "A Charging System for an Article of Footwear," (currently Attorney Docket No. <NUM>-<NUM>), and <CIT>, titled "A Control Device for an Article of Footwear," (currently Attorney Docket No. <NUM>-<NUM>).
