Abstract
A sole structure for an article of footwear includes a midsole having a first side with a first surface and a second side with a second surface. The first side has recesses extending toward the second side without extending to the second surface. A thickness of the midsole between the second side and a deepest extent of each of the recesses may be substantially uniform. Spacing of the recesses may correspond to a foot pressure map. The midsole may be a foam material that has a first density in a first portion along the first surface and a second density less than the first density in a second portion adjacent the first portion. A method of forming the midsole includes providing such recesses in the midsole such as by molding the midsole, and controlling a temperature of mold tools to achieve the first density in the first portion.
