Abstract
A midsole assembly for an athletic shoe includes a midsole formed of soft elastic material, and a corrugated sheet disposed in at least a heel portion of the midsole. The amplitude of the wave configuration of the corrugated sheet is larger at the medial and lateral sides of the heel portion and smaller at the central portion between the medial and lateral sides. Alternatively, the wave phase of the corrugated sheet is offset by one half of a wave pitch between the medial and lateral sides.
