ABSTRACT:
A suction-ventilated shoe system, which has air-exit ports located on the outer surface of said shoe, preferably in the midsole region, is provided. Said suction-ventilated shoe system contains a novel, multivented, suction-operated insole that enables the entire surface of said insole to be uniformly ventilated. Each air vent of said multivented, suction-operated insole contains its own independent, foot-operated, air-suction pump means, whose exhaust air is directed to exit the shoe via special air ducts that are connected between said insole's air-suction pump means and said shoe's air-exit ports. Each air-suction pump in said suction-operated insole has its own associated, one-way, air-valve means. A multiplicity of air vents may now be located anywhere over the entire surface of said insole and still maintain equal, air-suction, operating efficiency for each and every air vent. Said equal, air-suction, operating efficiency for each air vent is unaffected by which part of said insole is compressed first during each downstep, be it the heel part, the toe part or the entire insole at once. Also, said equal, air-suction, operating efficiency for each air vent is unaffected by whether or not said insole's air vents are only partially occluded by the sole of the foot during each downstep.
