Abstract: A footwear construction is provided including a sole assembly configured to slow a rate of pronation or roll during the gait cycle of a user. The sole assembly can include a midsole body, a stability platform joined with the midsole body, and a stability frame adjacent the midsole body and the stability platform on a medial side of the sole assembly. An outsole can be disposed below the midsole body and/or stability platform. The stability platform can include a lateral wing and a larger medial wing forming an unbalanced hourglass shape across the sole assembly. The stability frame and the stability platform on the medial side can be operatively configured to reduce a rate of pronation of a wearer of the footwear construction during a gait cycle of the wearer.

Abstract: A footwear construction including a sole assembly, which can include a midsole including a midsole support wall forming a compartment and a compression molded core constructed from thermoplastic polyester elastomer (TPEE) disposed in the compartment and shielded from abrasion in the environment of the footwear in use via the midsole support wall. The core can be formed by compressing a foam core to increase its density, for example, from a first density between 0.05 g/cm3 and 0.08 g/cm3, inclusive, to a second density between about 0.09 g/cm3 and 0.12 g/cm3, inclusive. Such compression molding and the attendant density increase of the TPEE core can increase energy efficiency to at least 95% energy efficiency, when the midsole is installed in footwear. A related method of manufacture is provided.
