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. |

1. A sandal with pneumatic support, comprising:
a generally flat sole having an upper surface, a lower surface, a core extending between the upper surface and lower surface, an arch area, a heel portion, and a periphery; a toe divider extending upwardly from the upper surface of the sole; a pneumatically distensible bladder disposed within the arch area of the sole; a manually actuated air pump communicating pneumatically with the bladder, the air pump being permanently and integrally connected to the bladder; a pressure relief valve communicating pneumatically with the bladder; and a plurality of foot-securing straps extending from the periphery of the sole, at least one of the straps having an air passage disposed therein, the bladder, the air pump, and the pressure relief valve communicating pneumatically with one another by means of the air passage in the at least one of the straps. |
