发明名称 Impact absorbing soles for parachutists
摘要 An impact absorbing device for parachutists is disclosed. A conventional overshoe may be modified by riveting or otherwise fastening hook and loop material to the bottom of the overshoe. An impact absorbing sole having a top surface including hook and loop material may be quickly attached to and detached from the modified overshoe. It is also contemplated to provide fastening straps in lieu of or in addition to the hook and loop fastener. The fastening straps may encircle the forefoot area and/or the heel and ankle. The sole may have three layers of solid material or the middle layer may include apertures, which correspond to the heel and ball areas of the foot, for receiving cushioning inserts. The layers may be made of a high density open cell urethane foam, a microcellular ethylene vinyl acetate (EVA) polyethylene foam, a viscoelastic plasticized polyurethane polymer, or a viscoelastic urethane rubber polymer. The layers may be laminated together using any conventional adhesive.
