Abstract
Abstract A high polymer resin material is configured into a shoe sole component having a plurality of inwardly extending indentations in one or both of the top and bottom members of the component. The indentations extend into the interval between the members and adjacent to the opposite member to provide support members for the sole component. The sole component can be constructed by molding upper and lower sole component halves wherein the molds are configured to provide indentations in the top and bottom members. The upper and lower sole component halves are then joined to complete the sole component.
