As shown in FIG. 1, article of footwear 100, also referred to simply as article 100, is intended to be used with a right foot; however, it should be understood that the following discussion may equally apply to a mirror image of article of footwear 100 that is intended for use with a left foot.
Referring to FIGS. 1 through 6, for purposes of reference, article 100 may include 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, article 100 may include medial side 16 and lateral side 18. In particular, medial side 16 and lateral side 18 may be opposing sides of article 100. Furthermore, both medial side 16 and lateral 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 article 100, but rather, to describe relative positions. Likewise, medial side 16 and lateral side 18 are intended to represent generally two sides of an article, rather than precisely demarcating article 100 into two halves. In addition, forefoot region 10, midfoot region 12 and heel region 14, as well as medial side 16 and lateral side 18, can also be applied to individual components of an article, such as a sole structure and/or an upper.
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 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 of an article. In other words, the lateral direction may extend between a medial side and a lateral side of an article. It will be understood that each of these directional adjectives may be applied to individual components of an article, such as a sole structure and/or an upper.
