Abstract: In its simplest conceptual form, the applicant's invention is the structure of a conventional shoe sole that has been modified by having its sides bent up so that their inner surface conforms to a shape nearly identical but slightly smaller than the shape of the outer surface of the sides of the foot sole of the wearer (instead of the shoe sole sides conforming to the ground by paralleling it, as is conventional). The shoe sole sides are sufficiently flexible to bend out easily when the shoes are put on the wearer's feet and therefore the shoe soles gently hold the sides of the wearer's foot sole when on, providing the equivalent of custom fit in a mass-produced shoe sole. This invention can be applied to shoe sole structures based on a theoretically ideal stability plane as a basic concept, especially including structures exceeding that plane.

Abstract: A shoe and an improved method of shoe construction comprising an upper, an insole, a midsole, and an outsole, that are coupled together to form a housing for receiving a foot, and wherein the midsole is enveloped by the bottom ends of the upper, the insole, and the outsole to provide a more secure and stable fit of the shoe to the foot. The shoe is constructed to have the midsole of the shoe enveloped by the combination of the upper, insole, and outsole. This method of shoe construction results in a shoe having an improved fit because the midsole is pulled from the top and the bottom to provide improved fit, support, stability, and cushioning characteristics.
