Abstract

An article of footwear may include an upper with an outer layer, an inner layer, and a chamber element positioned at least partially between the outer layer and the upper layer. The chamber element may be formed of two layers of a transparent colored polymer material and may be sealed to enclose a fluid. The chamber element may also have a plurality of subchambers. The outer layer may have a plurality of apertures. Each subchamber may protrude at least partially through a corresponding one of the apertures.

First claim

What is claimed is:

1. An article of footwear having an upper and a sole structure, the upper defining an interior void for receiving a foot of a wearer and comprising:
an outer layer forming part of an exterior surface of the footwear and having a plurality of outer apertures, at least one of the outer apertures being positioned at a rearward-facing portion of a heel region of the footwear;
an inner layer positioned adjacent the interior void and forming part of an interior surface of the footwear, the inner layer having a plurality of inner apertures; and
a fluid-filled chamber element positioned at least partially between the outer layer and the inner layer, the chamber element including:
an interior bond positioned on one of a lateral side of the upper and a medial side of the upper, and
a plurality of subchambers positioned adjacent to at least fifty percent of a periphery of the interior bond, the subchambers being in fluid communication with each other, and each of the subchambers protruding at least partially through one of the plurality of outer apertures and each of the subchambers protruding at least partially through one of the plurality of inner apertures.

2. The article of footwear of claim 1 , wherein the interior bond extends across at least twenty percent of an area of the chamber element.

3. The article of footwear of claim 1 , wherein the interior bond extends across at least fifty percent of a height of the chamber element and extends across at least twenty-five percent of a width of the chamber element.

4. The article of footwear of claim 1 , wherein the chamber element surrounds the heel region.

5. The article of footwear of claim 1 , wherein the chamber element is formed from a transparent colored polymer material.

6. The article of footwear of claim 1 , wherein the chamber element includes an additional interior bond and an additional plurality of subchambers adjacent to at least fifty percent of a periphery of the additional interior bond.

7. An article of footwear having an upper and a sole structure, the upper defining an interior void for receiving a foot of a wearer and comprising:
an outer layer forming part of an exterior surface of the footwear and having a plurality of outer apertures, at least one of the apertures being positioned at a rearward-facing portion of a heel region of the footwear;
an inner layer positioned adjacent the interior void and forming part of an interior surface of the footwear and having a plurality of inner apertures; and
a fluid-filled chamber element at least partially formed from a transparent colored polymer material, the chamber element being positioned at least partially between the outer layer and the inner layer, and the chamber element including a heel subchamber, a plurality of lateral subchambers, a plurality of medial subchambers, a lateral internal bond, and a medial internal bond,
wherein the heel subchamber and the plurality of lateral subchambers are adjacent to at least fifty percent of a periphery of the lateral internal bond, and the heel subchamber and the plurality of medial subchambers are adjacent to at least fifty percent of a periphery of the medial internal bond;
wherein at least one of the plurality of lateral subchambers protrudes at least partially through one of the plurality of inner apertures;
wherein the chamber element is configured to support an ankle of a wearer; and
wherein the chamber element is configured to extend around an Achilles tendon area and a calcaneus bone area of the wearer.

8. The article of footwear of claim 7 , wherein the heel subchamber has an elongate configuration.

9. The article of footwear of claim 7 , wherein a plurality of the medial subchambers have a triangular configuration and a plurality of the lateral subchambers have a triangular configuration.

10. The article of footwear of claim 7 , wherein the chamber element surrounds the heel region.

11. The article of footwear of claim 7 , wherein the medial internal bond and the lateral internal bond each extend across at least twenty percent of an area of the chamber element.

12. The article of footwear of claim 7 , wherein the medial internal bond and the lateral internal bond each extend across at least fifty percent of a height of the chamber element and extend across at least twenty-five percent of a width of the chamber element.

13. An article of footwear having an upper and a sole structure, the upper defining an interior void for receiving a foot of a wearer and comprising:
a material layer having a forward portion that forms part of an exterior surface of the upper in a forefoot region of the footwear; and
a fluid-filled chamber element that forms part of the exterior surface of the upper in both a midfoot region of the footwear and a heel region of the footwear, the chamber element having a first barrier layer and a second barrier layer that define a plurality of subchambers, each subchamber being exposed to an exterior of the footwear and being at least partially formed from a colored material;
the upper including an exterior layer and an interior layer, the exterior layer including a plurality of exterior apertures and the interior layer including a plurality of interior apertures that align with the plurality of exterior apertures;
wherein each of the plurality of subchambers protrudes at least partially through a respective one of the plurality of exterior apertures as well as protrudes at least partially through a respective one of the plurality of interior apertures.

14. The article of footwear of claim 13 , wherein at least one of the first barrier layer and the second barrier layer includes a colored portion.

15. The article of footwear of claim 13 , wherein at least one of the first barrier layer and the second barrier layer is a colored polymer material.

16. The article of footwear of claim 13 , wherein the colored material is a transparent polymer material.

17. The article of footwear of claim 13 , wherein the chamber element is formed from a transparent colored polymer material.

18. The article of footwear of claim 13 , wherein the chamber element surrounds the heel region.

19. The article of footwear of claim 13 , wherein the plurality of subchambers are in fluid communication with each other.

20. The article of footwear of claim 13 , wherein the chamber element includes an upwardly-extending inflation conduit located in the heel region.

21. The article of footwear of claim 13 , wherein the chamber element includes a peripheral bond extending around the subchambers.

22. The article of footwear of claim 21 , wherein the forward portion at least partially overlaps portions of the peripheral bond.

23. The article of footwear of claim 21 , wherein the peripheral bond includes a plurality of notches separating a plurality of flaps, and the flaps are secured to the sole structure.
