Abstract

An article of footwear is provided and includes an upper, a fluid-filled chamber including a first portion in contact with the upper in a first region, and a midsole including a first portion disposed between the fluid-filled chamber and the upper in a second region.

First claim

What is claimed is:

1. An article of footwear comprising:
an upper which defines a void to receive a foot of a wearer;
a fluid-filled chamber having a constant thickness extending continuously from a first end to a second end and including a first portion at the first end in contact with the upper in a first region; and
a cushioning pad including a first portion at the second end disposed between the fluid-filled chamber and the upper in a second region.

2. The article of footwear of claim 1 , wherein the first region is a heel region of the article of footwear and the second region is a forefoot region of the article of footwear.

3. The article of footwear of claim 1 , wherein the first portion of the fluid-filled chamber is in contact with a strobel of the upper in the first region.

4. The article of footwear of claim 3 , wherein the fluid-filled chamber is spaced apart from the strobel in the second region by the cushioning pad.

5. The article of footwear of claim 1 , wherein the fluid-filled chamber includes an arcuate shape in a direction extending from a heel region of the article of footwear toward a forefoot region of the article of footwear.

6. The article of footwear of claim 1 , wherein the fluid-filled chamber is disposed closer to the upper within a heel region of the article of footwear than in a forefoot region of the article of footwear.

7. The article of footwear of claim 1 , further comprising a tensile element disposed within the fluid-filled chamber.

8. The article of footwear of claim 1 , further comprising a ground-contacting surface, at least a portion of the fluid-filled chamber being visible at an opening of the ground-contacting surface.

9. An article of footwear comprising:
an upper including a strobel which defines a void to receive a foot of a wearer; and
a fluid-filled chamber having a constant thickness extending continuously from a first end to a second end and including a first portion at the first end in contact with the strobel and a second portion at the second end spaced apart from the strobel.

10. The article of footwear of claim 9 , further comprising a cushioning pad including a first portion disposed between the second portion of the fluid-filled chamber and the strobel.

11. The article of footwear of claim 9 , wherein the first portion is disposed in a heel region of the article of footwear and the second portion is disposed in a forefoot region of the article of footwear.

12. The article of footwear of claim 9 , wherein the fluid-filled chamber includes an arcuate shape in a direction extending from a heel region of the article of footwear toward a forefoot region of the article of footwear.

13. The article of footwear of claim 9 , wherein the fluid-filled chamber is disposed closer to the upper within a heel region of the article of footwear than in a forefoot region of the article of footwear.

14. The article of footwear of claim 9 , further comprising a tensile element disposed within the fluid-filled chamber.

15. The article of footwear of claim 9 , further comprising a ground-contacting surface, at least a portion of the fluid-filled chamber being visible at an opening of the ground-contacting surface.

16. The article of footwear of claim 9 , wherein the fluid-filled chamber extends continuously from the first portion to the second portion.

17. The article of footwear of claim 1 , further comprising a plate disposed adjacent to the fluid-filled chamber on an opposite side from the cushioning pad.

18. The article of footwear of claim 1 , further comprising a midsole including an upper surface portion defining a recess, the cushioning pad being received within the recess and including an upper surface flush with the upper surface portion of the midsole.

19. The article of footwear of claim 10 , further comprising a midsole including an upper surface portion defining a recess, the cushioning pad received within the recess and including an upper surface flush with the upper surface portion of the midsole.

20. The article of footwear of claim 19 , further comprising a plate disposed between the fluid-filled chamber and the midsole at the first portion and the second portion.
