Abstract

A cushioning and impact absorbing insole device adapted to be placed within articles of footwear including an upper layer and a lower layer formed of a flexible fluid impermeable material. The upper and lower layers are sealed together by a plurality of spaced surface lines contoured to parallel each other from the outer periphral edges to a selected inner spaced surface line thereby forming a plurality of sealed laterally spaced tubular members. The inner spaced surface line forms the inner main chamber which includes a heel chamber section, an arch chamber section, and a metatarsal chamber section. A transverse portion of the upper and lower layers of the arch chamber section are sealed together by spaced surface lines to form a plurality of fluid metering jet conduits. The transverse metering jet conduits control the flow of fluid, contained within the insole device, as it flows back and forth between the heel chamber section and the metatarsal chamber section as a result of transmission of forces of impact encountered by the foot of the wearer during application. The volume of fluid disposed within the chambers of the insole device only partially fills all of the chambers. The laterally spaced tubular members are adapted to be separately and selectively removed to thereby reduce the size of the insole device to thereby conform to the size of a selected foot wear article.
