The orthesis (1) is made by moulding polyurethane to produce a semi-rigid layer between the flipper (3) and the sole of the wearer's foot (2). The polyurethane is injected in liquid form between foot, which is covered by a sock and a layer of transparent plastic film to protect it from adhesion and heat during catalysis, and the surface of the flipper The thickness of the orthesis varies between about 1 mm and 2 cm, and its shape corresponds to that of the footprint.
