Abstract of the Invention A device which supports and cushions the human foot by means of fluid pressure is disclosed. The device is non- elastic and self-supporting. Two superimposed plies of a fluid impervious woven fabric material are sealed to each other around the periphery and, according to predetermined design, at selected areas within the periphery. The result is a series of foot supporting pneumatic cushions inter- spersed and separated with void regions which do not touch the underside of the foot. The fluid containing chambers which form the pneumatic cushions are in communication with each other through fluid passageways located around the periphery of the device. The device permits fluid to flow from one internal chamber to another when compressed, but with a back pressure build up sufficient to prevent sudden surges of fluid from one chamber to another. This provides additional pressure which resists and cushions the impact of the forces applied to the device.
