Abstract: The disclosure generally relates to a method for forming foamed shoe insoles as well as related shoe and shoe component articles. A foamed polymer having an open-cell foam interior structure and a continuous outer layer or skin can be formed conveniently such as by injection molding. The foamed polymer has a shape corresponding to two opposing shoe insole portions such that it can be cut or otherwise separated into two corresponding complementary foamed shoe insoles. The resulting open-cell foam interior structure and a continuous outer layer of the foamed shoe insoles can provide enhance spring or bounce effect when the insoles are incorporated into a shoe or sole component thereof.

Abstract: A disclosed shoe component includes: (a) a toe section, a heel section, a midfoot section therebetween, an exterior side and an opposed interior side, both extending from the heel section through the midfoot section and to the toe section; (b) a closed cell foam heel cup in the heel section; (c) a heel pad in the heel section at least partially surrounded by the heel cup; (d) a plurality of open cell foam members of varying firmness positioned in a movement pattern corresponding to a user's pressure movement Pattern and extending through the midfoot section and into the toe section; and (e) an optional toe closed cell foam member as a filler in the toe section. The open cell foam members can be positioned on either side of the center path corresponding to a movement configuration of a user to provide varying support on either side of the center path.
