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.
Claims39
A shoe sole structure, comprising:
- (a) a flexible sole-shaped top sheet of thermoplastic and having a plurality of indentations therein;
- (b) a flexible sole-shaped bottom sheet of thermoplastic and having a plurality of indentations therein;
- the bottom sheet joined at its periphery to the top sheet to form a cavity therebetween;
- (c) the indentations in the top sheet having sufficient depth to form projections extending inwardly into the cavity to abut indentations in the bottom sheet to retain the top member and bottom member in spaced relationship, each indentation forming a recess facing outwardly;
- at least one of the indentations in the top sheet or bottom sheet being hemispherical in shape.

A shock absorbing apparatus, comprising:
- (a) a first flexible high polymer resin sheet having an outer periphery and a plurality of hemispherical shaped indentations therein;
- and
- (b) a second flexible high polymer resin sheet coextensive with and attached to the first sheet and having an outer periphery and a plurality of hemispherical shaped indentations therein;
- (c) at least one hemispherical shaped insert configured for insertion into a hemispherical shaped indentation in the second sheet;
- and
- (d) a cavity between the first sheet and second sheet, the cavity coextensive with the first and second sheets, each of the plurality of hemispherical shaped indentations in the first and second sheets having sufficient depth to project inwardly into the cavity and having a recess facing outwardly.
3 more elements
A shoe sole component configured for incorporation into a shoe sole, comprising:
- (a) a top member formed of a flexible high polymer resin sheet;
- (b) a bottom member formed of a flexible high polymer resin sheet and being in at least partially coextensive relationship to said top member, said top and bottom members opposing one another and being in at least partially spaced relation to one another to define an interval therebetween;
- (c) a plurality of support members comprising inwardly directed indentations in the top member and opposing inwardly directed indentations in the bottom member, said indentations in each of said top and bottom members being integral with each of said members respectively and having sufficient depth to form a projection configured to extend into said interval and an outwardly facing recess, at least one of said inwardly directed indentations in each of said top and bottom members having a hollow hemispherical shape;
- (d) at least one insert having a hemispherical shape insertable into the recess of an inwardly directed indentation in the bottom member.
1 more element
A shoe sole structure, comprising:
- (a) a flexible top sheet having a plurality of indentations therein, each indentation including a recess on one surface of the sheet and a projection on the opposite surface of the sheet;
- (b) a flexible bottom sheet in parallel spaced relation with the top sheet and having an outer periphery and a plurality of indentations therein, each indentation including a recess on one surface of the sheet and a projection on the opposite surface of the sheet;
- (c) the projections of the indentations in the top sheet abutting the projections in the indentations in the bottom sheet;
- (d) a plurality of inserts insertable into the recesses of the indentations in one of the sheets;
- and
- (e) a webbed structure linking the plurality of inserts together.
