ABSTRACT:
Disclosed herein is a shoe construction, especially well suited for athletic footwear, comprising a one-piece molded sole having a bottom tread surface and an upper "fully orthopedic" foot supporting surface, a plurality of primary canals formed at the upper surface of the sole extending from the peripheral edges thereof inwardly in predetermined patterns, a foot supporting insole mounted upon the upper surface of the sole and cooperating with the primary canals to define ventilating air conduits, ventilating ports defined by the insole means and disposed in registry with the conduits, whereby ventilating air is free to communicate from exterior portions of the sole at peripheral portions thereof to the exposed internal surface of said insole, and a foot enclosing upper secured to said sole. Advantageously, the body of the sole between the canals is provided with cells or cavities which extend inwardly from the upper surface of the sole for the major portion of the thickness of said sole, whereby the cavities, in conjunction with the canals and the insole, provide the sole with an effective lightweight, strong, flexible and resilient honeycomb structure. Specifically, the lower portion of the sole is contoured to define a peripheral rim and a plurality of shock absorbing cylindrical members disposed inwardly thereof, the lower surfaces of the shock absorbing cylindrical members being disposed in a common plane with the peripheral rim, the cylindrical members being of sufficient depth so as to be compressible and laterally flexible in a manner whereby shock absorption is accommodated in three dimensions, along the X, Y and Z axes of the cylindrical members.
