Patent ID: 7337557

Claim:
An air-permeable shoe having an interior, comprising a sole with lateral surfaces, a recess formed on a sole upper surface, transverse grooves formed on a recess bottom surface, the transverse grooves communicating with vent holes formed on the lateral surfaces of the sole, an elastic block body fitted in the recess, upper portions of a block body protruding above the sole upper surface, vertical holes formed in the block body on the bottom surface of the recess, a support sheet provided so that when a load is applied, entry of the block body into the transverse grooves is prevented, the support sheet being air permeable, the shoe interior and transverse grooves communicating with one another through the vertical holes and support sheet, and when a load is applied to the block body, the vertical holes deform, thereby causing air to flow in and out between the vent holes and shoe interior.
