US Patent 10058144 Article of footwear with midsole with arcuate underside cavity

These recesses or cavities provide unique cushioning and support properties, particularly during “banking” (e.g., leaning to one side or pushing off to the side from the medial or lateral side of the foot). The recesses or cavities provide the structural benefits of dome or arch shapes that are formed in the mid-sole and open to the underside.
