Patent Images
1. An inner sole for a shoe, comprising:
- a generally flat sheet member made of resilient material;
said sheet member having a flat under surface with a plurality of openings therein which are upwardly enlarged to form air pockets, the material of said member extending across and thereby enclosing the upper sides of said air pockets;
whereby air flows through said openings out of or into the associated air pockets in response to impacts upon the upper surface of said member;
said sheet member also having a peripheral flange depending downwardly from the outer portion of the under surface thereof, said flange extending around most of the perimeter of said member; and
a gap in said flange so that air may flow into or out of the space between the under surface of said member and the supporting surface of a shoe within which said inner sole is placed.

Abstract
A resilient inner sole for a shoe is integrally formed from resilient material into a generally flat sheet member. The sheet member has a flat under surface with a plurality of openings which are upwardly enlarged to form air pockets, and the resilient material of the member extends over and thereby encloses the upper sides of the air pockets. When an impact is received upon an upper surface of the member, the member compresses, and air flows from the air pockets outward through the associated openings.
