## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of U.S. Patent Publication Number US2014/0075782, published Mar. 20, 2014 (application Ser. No. 14/032,373, filed Sep. 20, 2013), which is a division of U.S. Pat. No. 8,578,632, issued Nov. 12, 2013 (U.S. application Ser. No. 12/839,079, filed Jul. 19, 2010), both of which are herein incorporated by reference in their entirety.


BACKGROUND
The present invention relates generally to an article of footwear, and, in particular, to an article of footwear with a foot stabilizer system.
Conventional articles of footwear include two primary elements, an upper and a sole structure. The upper provides a covering for the foot that comfortably receives and securely positions the foot with respect to the sole structure. The sole structure is secured to a lower portion of the upper and is generally positioned between the foot and the ground. In addition to attenuating ground reaction forces, the sole structure may provide traction, control foot motions (e.g., by resisting pronation), and impart stability, for example. Accordingly, the upper and the sole structure operate cooperatively to provide a comfortable structure that is suited for a wide variety of activities.
Articles of athletic footwear are designed with a particular purpose in mind. Some articles of athletic footwear are designed to withstand jarring impact. Others are designed to withstand lateral impact. Some are designed to enhance stability. Others are designed to provide enhanced cushioning. The purpose for which a shoe will be used informs the design choices made by the designers.
Some athletic activities in particular may require frequent and quick lateral bodily movements. Sports including tennis and basketball are examples of athletic activities which require such dynamic lateral movements. The lateral movements require a secure foot plant to maintain stability. Without a secure footing, injuries can occur. Therefore, footwear which will provide lateral constraint for the foot during such lateral movements can be designed for performing such athletic activities.
While lateral constraint is one factor to be considered in designing athletic footwear, another factor is the weight and comfort of the athletic footwear. In general, athletic footwear is designed to be lightweight and to provide a comfortable fit.
Therefore, there exists a need in the art for an article of footwear that provides a customized fit to a wearer's foot and allows the wearer to move in a desired direction while also providing a level of stability.

DETAILED DESCRIPTION
The Figures disclose various exemplary embodiments of an article of footwear, also referred to simply as article, with a decoupled foot stabilizer system. A foot stabilizer system may be incorporated into any style of footwear including, for example, athletic footwear. A foot stabilizer system may be configured to provide lateral support to the foot of a user in sports requiring dynamic movement. For clarity, the following detailed description discusses articles of athletic footwear in the form of shoes associated with various sports, including, but not limited to: baseball, basketball, football, running, soccer, tennis, and other sports and activities where movement may be aided by an article of footwear provided with a foot stabilizer system. However, it should be noted that in other embodiments any other type of footwear could be used including, but not limited to: hiking boots, sneakers, as well as other kinds of shoes. Articles of footwear used with a foot stabilizer system may also take the form of any non-athletic shoe, including, but not limited to: dress shoes, loafers, sandals, and boots. An individual skilled in the relevant art will appreciate, therefore, that the concepts disclosed herein apply to a wide variety of footwear styles, in addition to the specific style discussed in the following material and depicted in the accompanying figures.
Additionally, while a single article of footwear is shown in the current embodiments, the same principles taught in this detailed description could be applied to a second, complementary article of footwear.
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 or major axis of an article. In some cases, the longitudinal direction may extend from a forefoot region to a heel region of the article. Also, the term “lateral” as used throughout this detailed description and in the claims refers to a direction extending a width or minor axis of an article. In other words, the lateral direction may extend between a medial side and a lateral side of an article. Furthermore, the term “vertical” as used throughout this detailed description and in the claims refers to a direction generally perpendicular to a lateral and longitudinal direction. For example, in cases where an article is planted flat on a ground surface, the vertical direction may extend from the ground surface upward. In addition, the term “proximal” refers to a portion of a footwear component that is closer to a portion of a foot when an article of footwear is worn. Likewise, the term “distal” refers to a portion of a footwear component that is further from a portion of a foot when an article of footwear is worn. It will be understood that each of these directional adjectives may be applied to individual components of an article, including an upper and/or a sole structure.
For purposes of general reference, an article of footwear may be divided into three regions: forefoot region 10, midfoot region 12, and heel region 14. Forefoot region 10 may be generally associated with the toes and joints connecting the metatarsals with the phalanges. Midfoot region 12 may be generally associated with the arch of a foot. Likewise, heel region 14 may be generally associated with the heel of a foot, including the calcaneus bone. In addition, an article of footwear may include lateral side 16 and medial side 18. In particular, lateral side 16 and medial side 18 may be opposing sides of the article. Lateral side 16 and medial side 18 may be located on either side of a longitudinal axis 20 bisecting the article. Furthermore, both lateral side 16 and medial side 18 may extend through forefoot region 10, midfoot region 12, and heel region 14.
It will be understood that forefoot region 10, midfoot region 12, and heel region 14 are only intended for purposes of description and are not intended to demarcate precise regions of an article of footwear. For example, in some cases, one or more of the regions may overlap. Likewise, lateral side 16 and medial side 18 are intended to represent generally two sides, rather than precisely demarcating an article of footwear into two halves. In addition, forefoot region 10, midfoot region 12, and heel region 14, as well as lateral side 16 and medial side 18, may also be applied to individual components of an article of footwear, including a foot stabilizer system, a sole structure, an upper, and/or any other component associated with the article.
FIGS. 1 through 10 illustrate an exemplary embodiment of an article of footwear 100 with a decoupled foot stabilizer system 120. Referring to FIG. 1, article of footwear 100 is shown in an exploded view. In some embodiments, article 100 may include a number of individual components. In this embodiment, article 100 includes decoupled foot stabilizer system 120. Article 100 additionally may include an upper 110 and a sole structure 140. Generally, upper 110 provides a covering for the foot that comfortably receives and securely positions the foot with respect to sole structure 140. Upper 110 may be made from any suitable material, including but not limited to, for example, nylon, natural leather, synthetic leather, natural rubber, or synthetic rubber. In some cases, upper 110 may be made of any suitable knitted, woven or non-woven material.
Sole structure 140 may be generally positioned between a foot of a wearer and the ground. In some embodiments, sole structure 140 may include one or more of an outsole, a midsole, a single piece sole, and/or any number of additional components associated with a conventional sole. In other embodiments, sole structure 140 may include one or more tread elements for engaging with the ground. While FIGS. 1 through 10 illustrate sole structure 140 having one or more tread elements, including a cleat, it should be understood that article 100 may include sole structure 140 as described herein without limitation to any specific type of tread element.
In some embodiments, sole structure 140 may further include a portion associated with a recess or a housing. In an exemplary embodiment, a recess or housing in a portion of sole structure 140 may be provided for receiving an electronic module, e.g., for sensing physical and/or physiological characteristics associated with use of the footwear or other devices.
In some embodiments, article 100 may include a base portion 130. Base portion 130 may be generally positioned between the foot of a wearer and sole structure 140. In some embodiments, base portion 130 may be secured to a lower portion of upper 110 and an upper portion of sole structure 140. In this embodiment, base portion 130 may be secured to a lower portion of upper 110 along an outer periphery 132. Additionally, in this embodiment, base portion 130 may be secured to a top surface 142 of sole structure 140. In different embodiments, base portion 130 may include one or more of a midsole, strobel, and/or a portion of upper 110 that is configured to be attached to sole structure 140.
In some embodiments, base portion 130 may be disposed between foot stabilizer system 120 and sole structure 140. In one embodiment, foot stabilizer system 120 may be secured to base portion 130. In an exemplary embodiment, foot stabilizer system 120 may be secured to base portion 130 in a manner such that foot stabilizer system 120 is selectively decoupled from one or more portions of article 100. As shown in FIG. 1, foot stabilizer system 120 may be selectively decoupled from a midfoot region of article 100 by securing foot stabilizer system 120 to base portion 130 along an attachment area having a narrower width than the width of base portion 130.
In this embodiment, base portion 130 may be associated with a first width W1 at a midfoot region. First width W1 generally corresponds to the width of article 100 at the midfoot region. In this embodiment, foot stabilizer system 120 may be attached to base portion 130 along an attachment area at the midfoot region defined by first attachment portion 134 and a second attachment portion 136. In other embodiments, foot stabilizer system 120 may be secured to base portion 130 at additional attachment portions located in other regions of article 100. In one embodiment, foot stabilizer system 120 optionally may be attached to a forefoot region and/or a heel region of base portion 130.
In one embodiment, first attachment portion 134 and second attachment portion 136 may be associated with a second width W2 at the midfoot region. In an exemplary embodiment, second width W2 is smaller than first width W1. In other embodiments, second width W2 may be substantially smaller than first width W1. By securing foot stabilizer system 120 along an attachment area that is narrower than base portion 130, a foot disposed inside article 100 may move foot stabilizer system 120 relative to the other components of article 100. With this arrangement, foot stabilizer system 120 may be selectively decoupled from one or portions of article 100.
In some embodiments, first attachment portion 134 and second attachment portion 136 may be disposed approximately similar distances from outer periphery 132 of base portion 130 on a medial side and a lateral side. In other embodiments, first attachment portion 134 and/or second attachment portion 136 may be associated with second width W2 disposed at dissimilar distances from outer periphery 132. In some cases, first attachment portion 134 may be located closer to outer periphery 132 on medial side. In other cases, second attachment portion 136 may be located closer to outer periphery 132 on lateral side. With this arrangement, foot stabilizer system 120 may be selectively decoupled in greater degree on a medial side or a lateral side of article 100.
In different embodiments, any one or more of the width of the attachment area and the number and location of attachment portions may be varied to provide different amounts of decoupling to foot stabilizer system 120 relative to base portion 130 and article 100.

In this embodiment, second height H2 may be larger than other embodiments where central attachment portion 131 has a larger width and/or where wider attachment areas are used to secure foot stabilizer system 120 and base portion 130, including, but not limited to a horseshoe shaped attachment area and/or an hourglass shaped attachment area, described below.
In other embodiments, one or more portions of foot stabilizer system 120 may provide additional stability for making lateral movements. In some cases, raised toe portion 206 and/or heel counter 204 may provide support to foot 600 of a wearer during cutting movements. In other cases, foot stabilizer system 120 and/or one or more of raised toe portion 206 and heel counter 204 may provide stability to foot 600 during other movements, including, but not limited to: moving in a forward or rearward direction, running, jumping and other athletic movements.
FIGS. 11 and 12 illustrate comparative views of lateral stability between a conventional article of footwear and an article of footwear with a foot stabilizer system according to the present embodiments described herein. Referring now to FIG. 11, a conventional article of footwear 101 is illustrated being worn on a foot 600 of a wearer. As the wearer makes a lateral movement, foot 600 shifts within conventional article 101, forming a bulge on one side of an upper 111 of conventional article 101. Additionally, the lateral movement by the wearer may cause an outsole 141 of conventional article 101 to become displaced from contact with a ground surface. As shown in FIG. 11, the lateral movement of foot 600 within conventional article 101 may cause outsole 141 to lift a height H6 from the ground surface on one side of conventional article 101. Accordingly, during lateral movements, conventional article 101 may not provide sufficient lateral stability to foot 600 of a wearer.
Referring now to FIG. 12, an exemplary embodiment of an article of footwear 100 including a foot stabilizer system is illustrated being work on foot 600 of a wearer. In this embodiment, article 100 is the exemplary embodiment shown in FIGS. 1-10 and described above. It should be understood, however, that other exemplary embodiments of articles of footwear including foot stabilizer systems described herein may provide substantially similar lateral stability as illustrated with respect to article 100 in FIG. 12.
In this embodiment, article 100 includes a foot stabilizer system comprising bootie 122 and strap members 200, as described above. Foot 600 of a wearer is supported by bootie 122 and strap members 200 within upper 110 of article 100. Additionally, as described above, the foot stabilizer system is attached to base portion 130 at a central attachment portion. With this arrangement, article 100 may allow foot 600 of a wearer to remain substantially parallel to a ground surface when the wearer is making a lateral movement. As shown in FIG. 12, the foot stabilizer system inside upper 110 provides support and lateral stability to foot 600 to prevent foot 600 from bulging out on one side of article 100. In addition, in contrast with conventional article 101 shown in FIG. 11, the foot stabilizer system of article 100 allows sole structure 140 to remain substantially in contact with the ground surface. As a result, article 100 does not lift above the ground surface to a height H6 as in the case with conventional article 101. With this arrangement, article 100 provides lateral stability to foot 600 of a wearer during lateral movements.
