Abstract

The sole unit (12) for a shoe includes a directional element (16), a cushioning element (18) and a heel cradle (20). The sole unit (12) may be attached to a shoe upper (14) by conventional methods, such as by gluing, stitching, or other means of bonding or physical attachment. The sole unit (12) provides foot support, cushioning, energy return, stability, torsion control, and optionally abrasion resistance to the user. The functional advantages of this construction of the sole unit (12) are primarily achieved through the directional elements (16) and cushioning element (18), each of which handle certain distinct functions of the shoe (10).
