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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
158 words
A shoe sole component comprising: (a) a flexible top sheet made from a high polymer resin and having substantially uniform thickness, an outer periphery, and a plurality of hollow, resiliently compressible indentations molded into the top sheet, each of the indentations having an upwardly facing recess and a downwardly facing projection; (b) a flexible bottom sheet made from a high polymer resin and having substantially uniform thickness, an outer periphery, and a plurality of hollow, resiliently compressible indentations molded into the bottom sheet, each of the indentations having a downwardly facing recess and an upwardly facing projection; (c) the top and bottom sheets joined at their outer peripheries whereby the top and bottom sheets are in spaced relation to one another to define a cavity therebetween, the projections of the indentations in the top and bottom sheets extending into the cavity, at least one of the indentations in the top sheet abutting an indentation in the bottom sheet.
Claim 2
Dependent Claim
158 words
A shoe sole component comprising: (a) a flexible top sheet made from a high polymer resin and having substantially uniform thickness, an outer periphery, and a plurality of hollow, resiliently compressible indentations molded into the top sheet, each of the indentations having an upwardly facing recess and a downwardly facing projection; (b) a flexible bottom sheet made from a high polymer resin and having substantially uniform thickness, an outer periphery, and a plurality of hollow, resiliently compressible indentations molded into the bottom sheet, each of the indentations having a downwardly facing recess and an upwardly facing projection; (c) the top and bottom sheets joined at their outer peripheries whereby the top and bottom sheets are in spaced relation to one another to define a cavity therebetween, the projections of the indentations in the top and bottom sheets extending into the cavity, at least one of the indentations in the top sheet abutting an indentation in the bottom sheet.
