<p>An outer sole (10) especially designed for basketball shoes which is lightweight, stable, and provides a greater degree of shock absorption than heretofore possible. The sole includes a plurality of kinetic levers or tread members (14-40) which extend downwardly and outwardly from the peripheral portion of the bottom (13) of the sole, a flexible side wall portion (52), and a relatively stiff, centrally formed pedestal (100) on the inside surface (17) of the sole, which together define a cantilevered construction that dissipates shock by inducing flexing and spreading of the tread members laterally outwardly upon foot-induced ground impact. The space between the inner, central pedestal (100) and the side wall (19) of the sole defines a cavity (104) positioned above the respective tread members for facilitating flexing, compression and spreading thereof to enhance the shock-dissipating qualities of the sole. The outwardly extending tread members and the side wall define a groove or recess (50) above the tread members, also facilitating flexure of the tread members and enhancing the shock dissipating qualities. The wider than normal base provided by the laterally extending tread members enhances stability and reduces the possibility of ankle twists. The forefoot portion of the bottom of the sole features a transversely extending groove pattern and a pivot stud which together facilitate metatarsal flexure and pivoting which are frequently encountered when playing basketball.</p> |
