  • the footwear plate 300 may be inserted through an opening in the textile such that a portion of the footwear plate 300 is internal to the textile (and/or is hidden from external view by the textile), and a portion of the footwear plate 300 is exposed and viewable from the outside of the textile.

  • footwear may be considered to be both a machine and a manufacture. Assembled, ready to wear footwear articles (e.g., shoes, sandals, boots, etc.), as well as discrete components of footwear articles (such as a midsole, an outsole, an upper component, etc.) prior to final assembly into ready to wear footwear articles, are considered and alternatively referred to herein in either the singular or plural as “article(s) of footwear” or “footwear”.
  • the term “longitudinal” refers to a direction extending along a length of a component.
  • 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” or “anterior” is used to refer to the general direction from a heel region toward a forefoot region, and the term “rearward” or “posterior” is used to refer to the opposite direction, i.e., the direction from the forefoot region toward the heel region.
  • a component may be identified with a longitudinal axis as well as a forward and rearward longitudinal direction along that axis.
  • the longitudinal direction or axis may also be referred to as an anterior-posterior direction or axis.
  • the term “transverse” refers to a direction extending along a width of a component.
  • a transverse direction of an article of footwear extends between a lateral side and a medial side of the article of footwear.
  • the transverse direction or axis may also be referred to as a lateral direction or axis or a mediolateral direction or axis.
  • the term “vertical” refers to a direction generally perpendicular to both the lateral and longitudinal directions. For example, in cases where a sole structure 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 structure.
  • the term “upward” or “upwards” refers to the vertical direction pointing towards a top of the component, which may include an instep, a fastening region and/or a throat of an upper.
  • the term “downward” or “downwards” refers to the vertical direction pointing opposite the upwards direction, toward the bottom of a component and may generally point towards the bottom of a sole structure of an article of footwear.
  • the “interior” of an article of footwear refers to portions at the space that is occupied by a wearer’s foot when the article of footwear is worn.
  • the “inner side” of a component refers to the side or surface of the component that is (or will be) oriented toward the interior of the component or article of footwear in an assembled article of footwear.
  • the “outer side” or “exterior” of a component refers to the side or surface of the component that is (or will be) oriented away from the interior of the article of footwear in an assembled article of footwear.
  • other components may be between the inner side of a component and the interior in the assembled article of footwear.
  • other components may be between an outer side of a component and the space external to the assembled article of footwear.
  • the terms “inward” and “inwardly” refer to the direction toward the interior of the component or article of footwear, such as a shoe
  • the terms “outward” and “outwardly” refer to the direction toward the exterior of the component or article of footwear, such as the shoe.
  • proximal refers to a direction that is nearer a center of a footwear component, or is closer toward a foot when the foot is inserted in the article of footwear as it is worn by a user.
  • distal refers to a relative position that is further away from a center of the footwear component or is further from a foot when the foot is inserted in the article of footwear as it is worn by a user.
  • distal may be understood to provide generally opposing terms to describe relative spatial positions.
