Abstract: Articles of footwear, including athletic footwear, include one or more of: (a) an upper; (b) a sole structure including a midsole and an outsole, the outsole having a plurality of polygonal lugs arranged about a base surface of the outsole. The outsole may include one or more regions wherein the characteristics of a portion of the lugs within a region differ from the characteristics of a portion of the lugs in another region. The lugs may differ, for example based on size, construction and/or spacing between the lugs. Methods of manufacturing such articles of footwear also are disclosed.

Abstract: A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the directional orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of geometrical patterns with polygonal apertures. The geometrical patterns have hinged polygons that rotate with respect to each other when the sole is under lateral or longitudinal tension, thus increasing the lateral and longitudinal dimensions of the sole.

Abstract: An article of footwear with a sole system includes a sole member and a protruding member assembly. The sole system provides tactile sensation. Protruding members of the protruding member assembly can translate through holes in the sole member to facilitate tactile sensation. Some embodiments can include an inner member that is configured to accommodate the movement of a protruding member. Other embodiments can include a plurality of recessed portions or nub portions formed along an outwardly facing surface of the sole member.

Abstract: Sole structures for articles of footwear, including athletic footwear, include: (a) a lightweight foam midsole component for supporting the foot; and (b) a plurality of heavier and/or denser cage components covering selected areas of the midsole component. Spaces are provided between the cage components. These spaces may be sized, shaped, and oriented to define and/or correspond to flexion lines of the foot and/or to produce a more natural flex motion to the sole. The soles additionally may include one or more outsole components, e.g., on bottom surface(s) of the cage component(s) and/or the foam midsole. These sole structures may be engaged with an upper to form a shoe. The uppers may include one or more lace receiving openings supported by elongated wire or textile components. Methods of making footwear including such uppers and/or sole structures also are described.

Abstract: An article of footwear is disclosed that includes an upper and a sole structure secured to the upper. The sole structure includes a midsole element, an upper sheet, and a lower sheet. The midsole element has an upper surface and an opposite lower surface. In addition, the midsole element defines a plurality of bores extending from the upper surface to the lower surface. The upper sheet is secured to the upper surface and extends over at least a portion of the bores. The lower sheet is secured to the lower surface, and the lower sheet is positioned to correspond in location with the upper sheet and extend under the portion of the bores.

Abstract: A tensile strand element for an article of footwear is disclosed. The tensile strand element includes one or more tensile strands secured at their endpoints between the sole and upper of an article of footwear, creating one or more looped portions. The unsecured looped portions may extend into the fastening region of the footwear and engage with a fastening system to tighten the footwear upper snugly against a wearer's foot to provide added support.

Abstract: A sole structure may include at least one plate. The at least one plate may include a first portion located in a forefoot region of the sole structure and a second portion located in a rearfoot region of the sole structure. At least one compressible midsole component may be coupled to the at least one plate. A linkage rod couples the first and second portions and is configured to bias the first and second portions away from one another during bending of the sole structure.

Abstract: Athletic performance sensing and/or tracking systems include components for measuring or sensing athletic performance data and/or for storing and/or displaying desired information associated with the athletic performance to the user (or others). Such systems can allow users a wide variety of options in creating workouts, selecting and presenting media content during the athletic performance, etc., e.g., to help keep users entertained and motivated. In some instances, user feedback may be used, optionally in combination with objective data relating to a workout, to control features of the workout routine, to control the music or other media content selected and/or presented, and/or to control features of future workout routines and/or the presented media content.

Abstract: An article of footwear includes first and second midsole layers and first and second outsole layers. The second midsole layer defines a plurality of bores. A first outsole layer is translucent. A second outsole layer includes a plurality of non-contiguous abrasion-resistant members that correspond in shape and size to one or more of the bores in the second midsole layer.

Abstract: A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the directional orthogonal to the direction under tension. The articles of footwear have sole components that have at least one layer made of a material that has a pattern of geometrical patterns. The geometrical patterns have hinged portions that rotate with respect to each other when the sole is under lateral or longitudinal tension, thus increasing the lateral and longitudinal dimensions of the sole. The sole component may include a pattern of recesses with varying depths, sizes, and shapes disposed along the inner surface as well as the outer surface of the sole component. In some cases the recesses may extend through the entire sole component layer.
