A flexible distal cup for use as part of a modular prosthetic socket for a residual limb may have a substantially closed distal end, an open proximal end, an inner surface and an outer surface. The flexible distal cup is configured to reside within an outer support structure of the prosthetic socket and to receive a distal portion of the residual limb. In some embodiments, the flexible distal cup may be made of a composite polymer composition, including an ethylene-vinyl acetate (EVA) copolymer and polycaprolactone (PCL). The EVA copolymer may be between about 45% and about 55% of the composite polymer composition by weight, the vinyl acetate of the EVA copolymer may be less than about 25% of the EVA copolymer by weight, and the PCL may be between about 45% and about 55% of the composite polymer composition by weight. |
