ABSTRACT:
An artificial jointless foot comprises a wooden core forming an upper connecting surface with an elastic synthetic material connected to the wooden core for forming the foot shape and guaranteeing a flexible rolling action. The wooden core forms, on the connecting surface, a dorsal stop for an adaptor connectable to the stop. Deformation of the connecting surface in the region of the dorsal stop is prevented, even when wood not resistant to such load is used for the wooden core. The wooden core has, in the region of the dorsal stop, a recess open at the top and filled with a duroplastic cast resin, the surface of which is in line with the connecting surface.
