This is sort of a "prototype" of 15th century cork pattens. It is based on a drawing of a cork patten that seems to have been at the Germanisches Nationalmuseum at some point (the notes to the drawing say that there is no inventory number). Cork pattens contain a thick cork insole covered by leather all around and were probably mostly used indoors to keep the feet insulated from cold floors. The elongated toe part is reinforced with brass underneath and wrapping around the point of the toe.
