Abstract

A shoe includes a sole having an insert piece and a layer of material disposed on a top surface of the insert piece; and an upper extending above the sole. The insert piece extends from at least one of a front or middle portion of the shoe to a rear of the shoe, with the top surface of the insert piece inclined upwardly toward the rear of the shoe and then leveling off at a rear portion of the shoe. A top surface of the layer of material is inclined upwardly from the at least one of the front or middle portion of the shoe to the rear of the shoe, such that at the rear portion of the shoe an angle of inclination is significantly greater for the top surface of the layer of material than for the top surface of the insert piece.

First claim

What is claimed is:

1. A high-heeled shoe, comprising:
a heel component which significantly elevates a rear portion of said high-heeled shoe, as compared to a front portion of said high-heeled shoe;
a sole having a layer of material disposed above the heel component;
a wedge-shaped component disposed between said heel component and said layer of material, wherein said wedge-shaped component includes a top surface with a front portion that inclines upwardly from a front section toward a rear section until reaching a transition edge and then turns substantially horizontal with respect to a bottom surface of an outsole at the heel component; and
an upper extending above and attached to the sole, wherein a top surface of the layer of material is inclined upwardly from the at least one of the front or middle portion of the high-heeled shoe to the rear portion of the high-heeled shoe, and wherein the layer of material increases in thickness at the rear portion of said high-heeled shoe, providing substantially more cushioning at said rear portion of said high-heeled shoe.

2. A high-heeled shoe according to claim 1 , wherein the wedge-shaped component is completely embedded within an outer material of the sole and, therefore, the wedge-shaped component is hidden from view.

3. A high-heeled shoe according to claim 1 , wherein the wedge-shaped component is substantially rigid.

4. A high-heeled shoe according to claim 1 , wherein the layer of material comprises a plurality of sublayers.

5. A high-heeled shoe according to claim 1 , wherein the layer of material comprises a separate cushioning element disposed only at the rear portion of said high-heeled shoe.

6. A high-heeled shoe according to claim 1 , wherein sidewalls of the layer of material also constitute sidewalls of the sole.

7. A high-heeled shoe according to claim 1 , wherein the sole further comprises an insole disposed above the layer of material.

8. A high-heeled shoe according to claim 7 , wherein the top surface of the layer of material at least approximately parallels the insole.

9. A high-heeled shoe according to claim 1 , wherein the layer of material is formed from a single, uniform type of material.

10. A high-heeled shoe according to claim 1 , wherein the layer of material is much thicker at the rear portion of the high-heeled shoe than said layer of material is within a middle section of the high-heeled shoe.

11. A high-heeled shoe according to claim 1 , wherein the layer of material extends approximately from a metatarsal region to the rear portion of said high-heeled shoe.

12. A high-heeled shoe according to claim 1 , wherein the heel component includes a spike heel.

13. A high-heeled shoe according to claim 12 , wherein the wedge-shaped component is integrated together with the spike heel as a unitary piece.

14. A high-heeled shoe according to claim 1 , wherein the top surface of the front portion of the wedge-shaped component has a front-to-rear upward slope that approximately matches a slope of the top surface of the layer of material.

15. A high-heeled shoe according to claim 1 , wherein the layer of material is substantially more cushioning than the heel component.

16. A high-heeled shoe according to claim 1 , wherein the layer of material increases in thickness from a front of the heel component to a rear of the heel component.

17. A high-heeled shoe according to claim 16 , wherein the layer of material increases in thickness only in a rear portion of said high-heeled shoe.

18. A high-heeled shoe according to claim 1 , wherein when traversing from front to rear, a support surface underneath the layer of material slopes upwardly and then levels off, while the layer of material continues to slope upwardly, thereby providing said increase in thickness of said layer of material at the rear portion of said high-heeled shoe.

19. A high-heeled shoe according to claim 1 , wherein the top surface of said layer of material maintains a substantially constant angle of inclination.
