Abstract: A shoe insert in the form of an envelope which is air impervious and having a pad of cushionable material positioned in the space defined within the envelope. The envelope is provided with a predetermined number of holes of predetermined diameter through the top surface thereof to provide controlled egress and ingress of air from and to the envelope as the wearer walks thereon and thereby providing unusual shock absorption and ventilation properties to the insert.

Abstract: A shoe insert in the form of an envelope which is air impervious and sized to fit within the shoe of a wearer and which is composed of an upper surface and a lower surface interconnected by a side surface and a pad arranged in spanning relation within the envelope, the pad being of cushioning material and preferably having a plurality of holes arranged in a pattern extending through the pad but not through the envelope. In one preferred embodiment the envelope is closed and some air withdrawn from the envelope before it is closed to provide an air cushion. In a second preferred embodiment, the envelope has a hole through it to create an air pump and circulation effect in the shoe of a wearer.
