1. A multi-layer prosthetic socket, comprising:
a rigid premade outer shell socket with an asymmetric inner surface contour with curves forming an inner depression to capture an insert socket with corresponding surface features;
a customized prosthetic insert socket with:
an asymmetric outer contour with outer curves forming an outer protrusion that corresponds to the inner depression of the asymmetric inner surface contour of the rigid premade outer shell socket,
wherein the asymmetric inner surface contour of the rigid premade outer shell socket operates to capture and secure the customized prosthetic insert socket within the rigid premade outer shell socket upon insertion of the customized prosthetic insert socket into the rigid premade outer shell socket,
an inner contour that corresponds to a residual limb surface contour of a residual limb of a patient, wherein the inner contour of the customized prosthetic insert socket can be adjusted to fit the residual limb surface contour without modifying the asymmetric outer contour of the customized prosthetic insert socket,
fastener-receiving apertures reinforced with a reinforcement material, and
a plurality of bladders formed within the customized prosthetic insert socket to be selectively filled to apply pressure on the residual limb of the patient,
wherein the asymmetric outer contour of the customized prosthetic insert socket is different than the inner contour of the customized prosthetic insert socket, such that the asymmetric outer contour of the customized prosthetic insert socket is non-conformal with the residual limb surface contour;
an attachment puck integrated within the rigid premade outer shell socket, the attachment puck comprising:
thru-bores to receive fasteners to fasten the rigid premade outer shell to the customized prosthetic insert socket, and
attachment features for fastening a prosthetic limb to the attachment puck; and
a bladder control device to control the selective filling of the plurality of bladders in the customized prosthetic insert socket.
