Abstract
A sole member for an article of footwear, comprises a sheet of resilient material displaying cushioning and memory properties. The sheet has a generally longitudinal cavity with outwardly flared sidewalls that deflect horizontally in the presence of a downward force. The cavity is wider in the heel region and curves outwardly toward the lateral forefoot to create a path of least resistance that causes the center of mass of the human body to migrate laterally and thereby reduce predisposition to excessive pronation.
