The sandal with pneumatic support includes an inflatable bladder in the sole, in the area immediately beneath the arch of the foot when the sandal is worn. A manual air pump is provided integrally with the sandal. In one embodiment, the pump is located atop the toe divider of a flip-flop type sandal. In another embodiment, the pump is located in the heel. A pressure relief valve is located along one of the upper straps of the sandal. The arch bladder, air pump, and relief valve communicate pneumatically with one another. The sandal may be devoid of structure extending between the toes when worn, but may include straps passing over and/or around the foot. The sandal provides greatly improved support and reduces or eliminates muscular problems resulting from the lack of arch support in sandals.
