Prosthesis cover

A prosthesis cover formed of waterproof sheet material having leg and foot portions, the foot portion having sole, toe and heel portions and side marginal edges between the toe and sole on both sides of the cover, an antiskid surface covering the foot portion, an open top end, the leg portion having a frusto-conical top segment for engagement with the prosthesis at the top end of the cover, finger loops positioned behind the heel and on opposite sides of the leg portion just below the open top, the leg and foot portions having contours and shape closely conforming to the shape of the prosthesis being covered, and a plurality of inwardly directed ribs being formed on the inner surface of the leg portion of the cover, the plurality of ribs being spaced apart from each other with each rib extending concentrically of the leg portion, the plurality of ribs extending along said inner surface from just above an ankle portion throughout the height of the leg portion to just below the top segment, so that the plurality of ribs spaces the inner cover surface from the prosthesis thereby to reduce frictional engagement when the cover is being applied by sliding over the prosthesis, and so that when the cover is in place the ribs engage the prosthesis and prevent the cover from slipping down along the prosthesis during use.
