Abstract: A shoe sole comprises an outer layer, a waterproof ventilation layer, and an inner layer. The outer layer is provided with a plurality of interstices penetrating the outer layer in such a way that the interstices deviate from the longitudinal direction of the outer layer by a predetermined angle, and that the interstices remain contiguous to one another at such time when the outer layer is not exerted on by an external force, and further that the interstices are so stretched as to enable both sides of the outer layer to communicate with each other at the time when the outer layer is deformed by an external force exerting thereon.
