Abstract:

A multi-durometer sole structure includes a sole structure body including a forefoot region, a heel region, and a midfoot region between the heel region and the forefoot region, a medial edge, and a lateral edge opposite the medial edge. The sole structure body further includes a first body segment extending along the forefoot region, the midfoot region, and the heel region, a second body segment extending along the forefoot region, the midfoot region, and the heel region, and a third body segment extending along midfoot region and the heel region. The first, second, and third body segments are made of different materials having three different hardnesses, respectively, such that a total hardness of the sole structure body varies from the medial edge to the lateral edge.
