A laminated panel is formable into a prosthesis. An outer layer of the panel has upper and lower surfaces, and is made of a thermoformable material. An inner layer of the panel has upper and lower surfaces, and is positioned relative to the outer layer such that the lower surface of the inner layer faces the upper surface of the outer layer. At least one reinforcement member has an area representing at most part of the upper surface of the outer layer. The reinforcement member is encapsulated between the inner and outer layers at a selected position relative to the outer layer, locally reinforcing the laminated panel. A prosthesis for a foot of a user made from a laminated panel, and a method of forming a prosthesis for a foot of a user with an outer layer of thermoformable material and an inner layer, are also described.
