Abstract

An article of footwear has an upper and a sole. The sole has an upper sole member, a lower sole member, and at least one inflatable bladder disposed between the upper sole member and the lower sole member. The at least one inflatable bladder has an inflated state and a deflated state. A distance between the upper sole member and the lower sole member is greater in the inflated state than the deflated state. Varying the inflation of the inflatable bladder varies the amount of cushioning in the sole and the thickness of the sole so that the shoe can serve as a multipurpose shoe for activities requiring different amounts of cushioning.

Claims (24)

1. A sole for an article of footwear, comprising:

an upper sole member having a peripheral surface;

a lower sole member having a peripheral surface facing the peripheral surface of the upper sole member;

at least one inflatable bladder disposed between and in contact with the upper sole member and the lower sole member wherein the at least one inflatable bladder has an inflated state and a deflated state and wherein a distance separating facing peripheral surfaces of the upper sole member and the lower sole member is greater in the inflated state than the deflated state; and

an air pressure regulator-operatively connected to the at least one inflatable bladder for regulating the air pressure therein,

wherein the at least one inflatable bladder comprises a plurality of chambers fluidly connected through at least one channel.

2. The sole of claim 1 , wherein the distance separating the upper sole member and the lower sole member at a first point along the length of the sole and a second point along the length of the sole is different.

3. The sole of claim 1 , wherein the at least one inflatable bladder is exposed when in the inflated state.

4. The sole of claim 1 , wherein the air pressure regulator is disposed on an outer surface of the upper sole member.

5. The sole of claim 1 , wherein the air pressure regulator is adapted to be adjusted by the wearer to set a desired air pressure in the at least one inflatable bladder.

6. The sole of claim 1 , wherein the air pressure regulator comprises an adjustable knob.

7. The sole of claim 6 , wherein the knob is rotatably adjustable.

8. The sole of claim 6 , wherein the knob is slidably adjustable.

9. The sole of claim 1 , further comprising a protective cover for covering at least a portion of the air pressure regulator.

10. The sole of claim 9 , wherein the protective cover extends from the lower sole member to the air pressure regulator.

11. The sole of claim 1 , wherein the at least one inflatable bladder further comprises:

a first inflatable bladder positioned in a forefoot area of the sole; and

a second inflatable bladder positioned in a heel area of the sole.

12. The sole of claim 1 , wherein the at least one inflatable bladder is positioned in a heel area of said sole.

13. The sole of claim 1 , wherein the at least one inflatable bladder is positioned in a forefoot area of the sole.

14. The sole of claim 1 , wherein the upper sole member includes an upper outer sidewall and the lower sole member includes a lower outer sidewall, and wherein a distance between the upper outer sidewall and the lower outer sidewall is greater in the inflated state than the deflated state.

15. The sole of claim 1 , wherein at least a portion of the bladder is monolithic over the plurality of chambers.

16. The sole of claim 1 , wherein the upper sole member and the lower sole member each defines a portion of an exterior surface of the sole.

17. The sole of claim 1 , wherein the at least one inflatable bladder is not disposed between the facing peripheral surfaces.
