ABSTRACT:
A shoe of the inflatable type having a midsole supporting member with a number of hollow downwardly extending support posts intercommunicated by channels recessed in the upper surface of the member. The upper surface is covered with a layer of natural rubber, to form enclosed air spaces with the hollows of the posts, and (in cooperation with the channels) conduits providing restricted passageways interconnecting the hollows of the posts. A valve extends from the exterior surface of the heel of the shoe to permit inflation by injection of air into the posts and conduits.
