Nylon stump sheaths perform the valuable function of providing a moisture barrier and controlling friction between the skin, stump socks and your prosthesis. Stump sheaths look like hosiery but are specially constructed at the distal end to offer maximum smoothness. The top and toe are reinforced so that pulling taut is possible; however, leaving a little slack is advised to prevent stressing the material. Stump sheaths are generally worn in combination with a thicker sock, creating a prosthetic sock system.
