Abstract
A composite sole structure for an article of footwear includes a bottom component and an intermediate component. Each of the intermediate component and the bottom component includes a protruding portion that forms a concave contour on the top surface and a corresponding convex contour on the bottom surface of the component, where the protruding portion includes at least a first portion that forms a continuous trough at least from a medial side of the forefoot region, e.g., from a medial side of a toe split, to a lateral side of the heel region, e.g., a heel strike region. The bottom component further includes a variable thickness profile that forms a continuous ridge on the bottom surface, the ridge extending from the medial side of the forefoot region to the lateral side of the heel region, the ridge being substantially aligned with the first portion of the protruding portion of the intermediate component and the bottom component.
