Abstract
A cushion-like, shock-absorbent insole for footwear comprises two vinyl sheets forming an airtight compartment and sealing therein one or more sheets of resilient foam. Vent holes arranged in at least one of the vinyl sheets, preferably at the heel and metatarsal areas, act as metering valves in conjunction with the inside surface of the shoe sole so that air trapped in the foam material cannot instantaneously escape and both cushioning and massaging are provided.
