Abstract:

A sandal with a pressure-adjustable air cushion includes a platform with a recess formed therein for receipt of a cushion. The cushion has a foot-engaging pad attached to a bladder. The pad is made of a thicker, somewhat less flexible material than the bladder which is made of a highly flexible material but strong enough to withstand the pressure applied by the feet of an individual wearing the sandal. The pad rides on top of the bladder and is adhered to the platform to hold bladder in place in the recess. The gas in the cushion can be evacuated or replenished through a valve in its side, ideally near the instep, by using a small valve and pressurized canister preferably containing carbon dioxide or other suitable gases.
