    摘要： A sole structure for an article of footwear includes a unitary sole with a first cushioning body having a first hardness and a second cushioning having a second hardness greater than the first hardness. Both the first and the second cushioning bodies are exposed at a periphery of the sole. The second cushioning body may have a wedge surface that interfaces with a lateral extremity of the first cushioning body and angles laterally outward toward a lateral side exterior surface of the sole from a lower extent to an upper extent of the wedge surface. The second cushioning body may underlie the first cushioning body in a portion of a forefoot region of the sole such that the first cushioning body establishes a foot-facing exterior surface and the second cushioning body establishes a ground-facing exterior surface of the sole where the first cushioning body overlies the second cushioning body.

    摘要： A sole structure for an article of footwear includes a connecting portion coupled to a siped portion. The connecting portion extends across the sole structure, with an upper surface operative to be secured to an upper of the article of footwear. The siped portion extends from a ground-facing side of the connecting portion and includes a plurality of sole elements. Each of the plurality of sole elements is at least partially defined by one or more of a plurality of sipes that extend from the ground-contacting surface to the ground-facing side of the connecting portion. At least one of the plurality of sipes is a lateral sipe that is located within the midfoot region and extends from the medial side to the lateral side of the sole structure. This at least one lateral sipe is sized to permit plantarflexion of the sole structure without deformation of an adjacent sole element.
