Abstract: A flexible inner socket is fabricated by forming a pre-socket. The pre-socket includes a body formed with an opening and an enclosed end. The enclosed end is opposite to the opening. The body of the pre-socket has an outer circumference that is smaller than the inner circumference of the rigid prosthetic socket. Different portions of the body may have different thicknesses. The preform socket is heated. After the heating, the flexible inner socket is formed by molding the pre-socket onto the inner surface of the rigid prosthetic socket to form the flexible inner socket. The inner circumference of the rigid prosthetic socket is reduced by a thickness of the flexible inner socket when the flexible inner socket is attached to the inner surface of the rigid prosthetic socket. An opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

Abstract: A flexible prosthetic inner socket that resides inside of a rigid prosthetic socket that is fabricated by forming a sized, injection molded, flexible inner pre-socket. The flexible inner pre-socket includes a body formed with an opening and an enclosed end. The Pre-socket can be heated and stretched over a prosthetic residual limb model and then a prosthetic rigid socket can be formed over it. It can also be heated and vacuum-formed inside of an existing hard prosthetic socket in order to provide global volume reduction intended to make the rigid prosthetic socket fit tighter onto the residual limb. The opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

Abstract: A boot having a shoe shaped shell member and a cuff member having a section overlapping the shell member. The cuff and shell members are pivotally connected together for pivoting movement in response to pivoting of the individual's leg relative to the individual's foot. An elastomeric material is disposed between said shell member to pivotally connect the two members together.
