In one embodiment, a double-wall prosthetic limb socket assembly includes: (a) a first substantially rigid inner-wall socket adapted to receive a patient's residual limb; and (b) a second substantially rigid outer-wall socket seating the first inner-wall socket therein, the second outer-wall socket including, (i) a distal, circular base-plate; and (ii) a molded circumferential wall bonded to and extending proximally from the distal, circular base-plate; where the circular base-plate includes a vacuum port extending radially from a circumferential outer side of the base-plate in fluid communication with a vacuum channel extending through the circular base-plate and out through an outlet hole in a proximal side of the circular base-plate; such that when the vacuum port is coupled to a vacuum pump, the vacuum will help to draw the first inner-wall socket into the second outer-wall socket. A resilient, roll-on liner with a substantially closed distal end and an open proximal end interposes the substantially rigid inner and outer wall sockets.
