    Abstract: A plurality of sheaths extend along the sleeve of a socket prosthesis. The outermost, or retaining sheath is open at top and bottom and extends from above the sleeve down over the prosthesis itself. Different portions of the retaining sheath have different degrees of elasticity. An inner sheath is first folded over the top edge of the retaining sheath, and then folded again, together with the retaining sheath, to form a welt which abuts against the upper edge of the prosthesis sleeve.
