ABSTRACT:
A method of constructing a water ski foot support results in a foot support with a tough vinyl backing and a soft cushion layer for comfort. First the backing is injection molded. During the injection molding, a raised rim is formed on the inner side of the backing. The backing is then supported in a horizontal position with its inner side facing upward. A plastisol resin is poured onto the inner side at room temperature. The backing and plastisol resin are heated, the heat causing the plastisol resin to change into a solid cushion layer, bonded to the backing.
