ABSTRACT:
On the upper surface of a lower sole transverse grooves reaching the lateral surface of the sole are formed, and an upper sole in which a recess is formed is stacked on the lower sole. In the recess, an elastic block body is fitted so that the upper portions of the block body protrude above the upper surface of the upper sole. On the upper surface of the lower sole, an air-permeable support sheet is disposed so as to support the block body in the recess. The shoe interior and tranverse grooves communicate with one another through the vertical holes in the block body and the support sheet, and when a load is applied to the block body, the vertical holes deform, causing air to flow in and out through the tranverse grooves.
