Abstract
An athletic shoe to provide a safe orientation of the foot during an immediate stop in the medial lateral direction and to preclude hyperinversion of the foot in the subtalar joint is shown. The shoe sole has an upper sole member and a lower sole member which are elastically connected by a resilient member along the lateral and medial edges of the shoe. The upper and lower sole members are each wedge-shaped and disposed in opposite orientation in sliding engagement along confronting concave-convex surfaces having corresponding curvatures. The upper and lower sole members may include medial to lateral extending ribs. A lubricant may be provided between the confronting surfaces and the ribs.
