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, such as a training shoe and a racing flat.

What is claimed is: 1. A sole for an article of footwear, the sole comprising: an upper sole member; a lower sole member; and at least one inflatable bladder disposed between said upper sole member and said lower sole member wherein said at least one inflatable bladder has an inflated state and a deflated state and wherein a distance between said upper sole member and said lower sole member is greater in the inflated state than the deflated state, wherein said lower sole member has an upper surface, a lower surface and a side surface connecting said upper surface and said lower surface; said at least one inflatable bladder has at least one portion that folds over said side surface of said lower sole member; and a first surface of said at least one inflatable bladder attaches to a lower surface of said lower sole member. 2. The sole of claim 1, wherein said at least one inflatable bladder further comprises: a first inflatable bladder positioned in a forefoot area of said sole; and a second inflatable bladder positioned in a heel area of said sole. 3. The sole of claim 1, wherein said at least one inflatable bladder is positioned in a forefoot area of said sole. 4. The sole of claim 1, wherein said at least one inflatable bladder is positioned in a heel area of said sole. 5. The sole of claim 1, wherein said upper sole member comprises an opening for holding a manifold. 6. The sole of claim 1, further comprising an outsole attached to a second surface of said at least one portion of said at least one bladder. 7. The sole of claim 6, wherein said outsole is a flexible material such that when said at least one portion of said at least one bladder is in the inflated state a profile of said outsole expands to accommodate the inflated said at least one portion. 8. The sole of claim 7, wherein: said upper sole member has a lower surface; said lower surface of said upper sole member and said upper surface of said lower sole member are recessed to correspond to a shape of a portion of said at least one inflatable bladder located between said upper sole member and said lower sole member; and said lower surface of said lower sole member is recessed to correspond to a shape of said portion of said at least one inflatable bladder that is located between said lower sole member and said outsole. 9. The sole of claim 1, wherein said side surface has at least one groove located where said at least one portion of said inflatable bladder folds over said side surface. 10. The sole of claim 1, wherein: said upper sole member has a recessed lower surface corresponding to a shape of said at least one inflatable bladder; and said lower sole member has a recessed upper surface corresponding to a shape of said at least one inflatable bladder. 11. The sole of claim 1, further comprising: at least one plate having a first surface and a second surface wherein said first surface is attached to a lower surface of said upper sole member and said second surface is attached to a surface of said inflatable bladder. 12. The sole of claim 1, further comprising: at least one plate having a first surface and a second surface wherein said first surface is attached to an upper surface of said lower sole member and said second surface is attached to a surface of said inflatable bladder. 13. The sole of claim 1, further comprising: at least one first plate having a first surface and a second surface wherein said first surface is attached to a lower surface of said upper sole member and said second surface is attached to a first surface of said inflatable bladder; and at least one second plate having a first surface and a second surface wherein said first surface is attached to an upper surface of said lower sole member and said second surface is attached to a second surface of said inflatable bladder. 14. The sole of claim 1, wherein said at least one inflatable bladder comprises: a formed substrate; and a film attached to a periphery of said formed substrate. 15. The sole of claim 14, wherein said formed substrate is blow molded. 16. The sole of claim 14, wherein said formed substrate is thermoplastic polyurethane. 17. The sole of claim 14, wherein: said lower sole member has an upper surface with a cavity; and said formed substrate is adjacent said cavity. 18. The sole of claim 14, wherein: said upper sole member has a lower surface with a cavity; and said formed substrate is adjacent said cavity. 19. An article of footwear comprising: an upper; and a sole comprising: an upper sole member; a lower sole member; and at least one inflatable bladder disposed between said upper sole member and said lower sole member wherein said at least one inflatable bladder has an inflated state and a deflated state and wherein a distance between said upper sole member and said lower sole member is greater in the inflated state than the deflated state, wherein said lower sole member has an upper surface, a lower surface and a side surface connecting said upper surface and said lower surface; said at least one inflatable bladder has at least one portion that folds over side surface of said lower sole member; and a first surface of said at least one inflatable bladder attaches to a lower surface of said lower sole member. 20. The article of footwear of claim 19, wherein said upper sole member has an opening. 21. The article of footwear of claim 20, further comprising: a manifold located in said opening in said upper sole member wherein said at least one inflatable bladder is fluidly connected to said manifold; and an underfoot pump fluidly connected to said manifold that transfers air through said manifold and into said at least one inflatable bladder for inflating said at least one inflatable bladder. 22. The article of footwear of claim 21, further comprising: an air pressure regulator. 23. The article of footwear of claim 22, where air pressure regulator regulates pressure in said at least one inflatable bladder and bleeds off air when the pressure meets a threshold value. 24.
