Abstract: An article of footwear includes an outsole that has a bottom portion and a medial arch portion extending upward from the bottom portion. The medial arch portion of the outsole has a base and a plurality of protrusions extending outward from the base. The plurality of protrusions are arranged in vertical alignments. In each one of the vertical alignments, at least one protrusion of the plurality of protrusions is closer to the bottom portion and has a larger effective diameter than at least one other protrusion of the plurality of protrusions that is further from the bottom portion.

Abstract: An article of footwear includes a sole structure that has a heel portion with a rear, a lateral side, and a medial side. The article of footwear includes a heel extender that has a rear segment disposed at the rear of the heel portion, a lateral arm disposed at the lateral side of the heel portion, and a medial arm disposed at the medial side of the heel portion. The heel extender has a protuberance that establishes a rearmost extent of the article of footwear. The sole structure has a first hardness and the protuberance has a second hardness greater than the first hardness.

Abstract: An article of footwear includes an outsole having a heel region, a midfoot region, and a forefoot region. An outer midsole layer is secured to the outsole and extends only over the heel region and at least some of the midfoot region. An inner midsole layer is supported by the outer midsole layer and the outsole without being fixed thereto, and extends over the heel region, the midfoot region, and the forefoot region. The outer midsole layer is configured to surround a periphery of the inner midsole layer at the heel region. The outsole may include lateral and medial arch portions for traction.

Abstract: Various arrangements for an article of footwear including an outsole having grooves forming discrete lugs are presented. The outsoles generally include a plurality of grooves formed in at least a portion of the outsole that extend from a lateral side of the outsole to a medial side of the outsole. The grooves may be linear or curved and generally extend in an angular fashion. The grooves may have a first depth at a perimeter of the outsole and a second depth, greater than the first depth, at the center of the outsole. The grooves form discrete lugs. In some arrangements, the lugs are diamond shaped.

Abstract: Footwear including removable and replaceable outsole members may include: (a) an upper member; (b) a midsole member, having an exterior surface not designed for performance use in direct contact with the ground, fixedly engaged with the upper member; and (c) an outsole member designed for performance use in contact with the ground removably attached over at least a major portion of the midsole member. The outsole member may attach to the midsole member and/or upper member in a variety of different ways. In use, the wearer may select a specific set of outsole members to use at a given time depending, for example, on the type of play surface, temperature, and/or other conditions. Worn outsole members may be replaced without the expense involved in also replacing the remainder of the footwear.

Abstract: An article of footwear includes a sole assembly and an upper secured to the sole assembly. A sole plate is positioned between the upper and the sole assembly. The sole plate includes a midfoot member comprising a medial member having a base plate and at least one medial pillar extending upwardly from a medial edge of the base plate; with the base plate having a substantially planar finger extending forwardly and configured to extend under a foot of a user; and a lateral member having at least one lateral pillar extending upwardly from a lateral edge thereof. A forefoot member has at least one finger extending upwardly along an exterior surface of the upper.
