ABSTRACT:
A releasable attachment is provided for parachutists' footwear to lessen the impact upon landing and to prevent injuries to the ankles, legs, knees and other body areas. The attachment consists of a fluid filled cavity and a blowout plug. The attachment is formed from a somewhat flexible polymeric material in which the cavity will collapse upon impact. The fluid contained therein will dispel and the blowout plug will release therefrom to dissipate the impact energy. The reservoir is affixed with straps to the footwear. The attachment can be quickly placed on the soles of the footwear before exiting the aircraft and easily removed after the parachutist lands. The cavities can be refilled and the blowout plugs replaced when the parachute is repacked.
