Abstract

An article of footwear having an upper with enhanced transition properties is described herein. The transition properties may be incorporated in an ankle collar trim transition region, a heel stay reinforcing structure, and/or a heel padding structure. Additionally, a method for manufacturing the article of footwear with enhanced transition properties in a heel region is provided.

Claims

1. An upper of an article of footwear having an exterior surface, an interior surface, and an ankle collar, the upper comprising:

an inner material extending to the ankle collar, the inner material having an interior surface and an opposing outer surface, the inner material comprising a thickness continuously extending from the interior surface to the opposing outer surface, and wherein the interior surface and the opposing outer surface terminate at a top edge of the inner material; and

an upper first material extending to the ankle collar, wherein the inner material extends upwardly beyond the upper first material at the ankle collar such that the opposing outer surface of the inner material forms at least a portion of the exterior surface and the interior surface of the inner material forms at least a portion of the interior surface of the article of footwear, wherein the top edge of the inner material is superior to a top edge of the upper first material at the ankle collar.

2. The upper of the article of footwear of claim 1, further comprising an ankle collar reinforcing material that overlaps the top edge of the upper first material and retains the top edge of the upper first material in contact against the opposing outer surface of the inner material.

3. The upper of the article of footwear of claim 2, wherein the ankle collar reinforcing material extends around a heel end of the upper from a medial side of the upper to a lateral side of the upper.

4. The upper of the article of footwear of claim 2, wherein the ankle collar reinforcing material comprises an elongate band.

5. The upper of the article of footwear of claim 2, wherein the ankle collar reinforcing material comprises a thermoplastic material.

6. The upper of the article of footwear of claim 5, wherein the ankle collar reinforcing material is thermally bonded to each of the upper first material and the inner material.

7. The upper of the article of footwear of claim 2, wherein the top edge of the inner material is superior to a top edge of the ankle collar reinforcing material, and a top edge of the ankle collar reinforcing material is superior to the top edge of the upper first material at the ankle collar.

8. The upper of the article of footwear of claim 7, further comprising:

a first ankle collar trim transition region comprising the inner material, and not comprising the upper first material nor the ankle collar reinforcing material;

a second ankle collar trim transition region comprising the inner material and the ankle collar reinforcing material, and not comprising the upper first material; and

a third ankle collar trim transition region comprising the inner material, the ankle collar reinforcing material, and the upper first material.

17. The upper of the article of footwear of claim 1, wherein the interior surface is separated from the opposing outer surface of the inner material by a top surface at the top edge of the inner material.

19. The upper of the article of footwear of claim 1, wherein the inner material is a single layer.

9. An article of footwear having an exterior surface and an interior surface, comprising:

a sole; and

an upper, the upper comprising;

a toe end;

a heel end;

a medial side;

a lateral side; and

a heel region extending between the medial side and the lateral side at the heel end, the heel region comprising;

an ankle collar;

an upper first material extending from proximate the sole to the ankle collar; and

an inner material extending from proximate the sole to the ankle collar, wherein the inner material comprises;

an outer surface forming a portion of the exterior surface of the article of footwear,

an inner surface that forms at least a portion of the interior surface of the article of footwear, the inner surface opposing the outer surface, a thickness continuously extending from the inner surface to the outer surface, and

a top edge of the inner material that is superior to a top edge of the upper first material at the ankle collar wherein the outer surface and the inner surface terminate at the top edge of the inner material.

10. The article of footwear of claim 9, further comprising an ankle collar reinforcing material that overlaps the top edge of the upper first material and retains the top edge of the upper first material.

11. The article of footwear of claim 10, wherein the ankle collar reinforcing material comprises an elongate thermoplastic band that extends around the heel end of the upper from the medial side of the upper to the lateral side of the upper.

12. The article of footwear of claim 11, wherein the ankle collar reinforcing material is thermally bonded to each of the upper first material and the inner material.

13. The article of footwear of claim 9, further comprising a heel stay reinforcing structure positioned at the heel region exterior surface.

14. The article of footwear of claim 9, further comprising a heel stay reinforcing structure inferior to the top edge of the inner material.

15. The article of footwear of claim 9, further comprising a heel padding region disposed in the heel region between the inner material and the upper first material, and between a heel region top edge and a heel region bottom edge.

16. The article of footwear of claim 9, wherein the inner material extends from a heel region bottom edge to a heel region top edge.

18. The article of footwear of claim 9, wherein the inner surface is separated from the opposing outer surface of the inner material by a top surface at the top edge of the inner material.

20. The article of footwear of claim 9, wherein the inner material is a single layer.
