ABSTRACT:
This split vamp athletic shoe (10) includes separated upper and lower vamp sections (18, 22) which are independently adjustable and provide the shoe with a hinge zone providing the shoe with flexibility. The shoe also includes an outsole (14) and a midsole (16), the outsole being unitarily formed to include upwardly extending instep support portions (36) which are attached to the upper vamp and extend substantially to the leading edge of the upper vamp to stiffen the shoe particularly in the instep area and provide stabilizing restraint against lateral motion and enhance the hinge action. The outsole also includes a second set of upwardly extending side support portions (38) which are spaced from said instep side support portions. In a second embodiment the midsole (116) includes unitarily formed side portions (166) recessed to receive the outsole side portions (136) and cooperating with said side portions to provide additional lateral stabilization and further enhancing the hinge action.
