An article of footwear has an upper and a sole. The sole has at least one inflatable bladder wherein said at least one inflatable bladder has an inflated state and a deflated state. A ground engaging surface of the sole has a first profile in the deflated state and a second profile in the inflated state. The first profile is different from the second profile. Varying the profile of the ground engaging surface varies the amount of cushioning in the sole so that the shoe can serve as a multipurpose shoe for activities requiring different amounts of cushioning.

The sole of claim 1, wherein at least one of said plurality of individual outsole pieces extend away from the sole when said at least one inflatable bladder is in said inflated state. 3. The sole of claim 2, further comprising a midsole wherein said midsole has a lower surface that is recessed to correspond to a shape of said at least one inflatable bladder for storing said at least one inflatable bladder in said deflated state. 4. The sole of claim 2, wherein said at least one inflatable bladder comprises a plurality of interconnected chambers. 5. The sole of claim 4, wherein each of said chambers is located above one of said plurality of individual pieces that extend away from the sole when said at least one inflatable bladder is in said inflated state. 6. The sole of claim 1, wherein said at least one inflatable bladder comprises a plurality of interconnected chambers. 7. The sole of claim 1, wherein said at least one inflatable bladder comprises: a first inflatable bladder positioned in a forefoot region of said sole; and a second inflatable bladder positioned in a heel region of said sole. 8. The sole of claim 7, wherein said first inflatable bladder comprises a plurality of interconnected chambers. 9. The sole of claim 7, wherein said second inflatable bladder comprises a plurality of interconnected chambers. 10. The sole of claim 1, wherein said at least one inflatable bladder is positioned in a forefoot region of said sole. 11. The sole of claim 1, wherein said at least one inflatable bladder is positioned in a heel region of said sole. 12. The sole of claim 1, further comprising; at least one plate having a first surface and a second surface, wherein said second surface is attached to a surface of said at least one inflatable bladder; and a midsole having a lower surface, wherein said lower surface is attached to said first surface of said at least one plate. 13. The sole of claim 12, wherein said lower surface of said midsole is recessed to correspond to a shape of said at least one inflatable bladder and said at least one plate for storing said at least one inflatable bladder and said at least one plate in said deflated state. 14. The sole of claim 1, wherein said sole has an opening for holding a manifold. 15. A sole for an article of footwear, the sole comprising: at least one inflatable bladder comprising a first film and a second film sealed to said first film, wherein said at least one inflatable bladder has an inflated state and a deflated state; and a ground engaging surface comprising an outsole having a first profile in said deflated state and a second profile in said inflated state, wherein said first profile is different from said second profile in that at least a portion of said outsole expands to accommodate said at least one inflatable bladder when said at least one inflatable bladder moves from said deflated state to said inflated state. 16. The sole of claim 15, further comprising a midsole wherein said midsole has a lower surface that is recessed to correspond to a shape of said at least one inflatable bladder for storing said at least one inflatable bladder in said deflated state. 17. The sole of claim 15, wherein said at least one inflatable bladder comprises a plurality of interconnected chambers. 18. The sole of claim 15, wherein said at least one inflatable bladder comprises: a first inflatable bladder positioned in a forefoot region of said sole; and a second inflatable bladder positioned in a heel region of said sole. 19. The sole of claim 18, wherein said first inflatable bladder comprises a plurality of interconnected chambers. 20. The sole of claim 18, wherein said second inflatable bladder comprises a plurality of interconnected chambers. 21. The sole of claim 15, wherein said at least one inflatable bladder is positioned in a forefoot region of said sole. 22. The sole of claim 15, wherein said at least one inflatable bladder is positioned in a heel region of said sole. 23. The sole of claim 15, wherein an edge of said outsole is attached to said at least one inflatable bladder. 24. The sole of claim 15, wherein an edge of said outsole is attached to a midsole located above said at least one inflatable bladder. 25. The sole of claim 15, further comprising: at least one plate having a first surface and a second surface, wherein said second surface is attached to a first surface of said at least one inflatable bladder; and a midsole having a lower surface, wherein said lower surface is attached to said first surface of said at least one plate. 26. The sole of claim 25, wherein said lower surface of said midsole is recessed to correspond to a shape of said at least one inflatable bladder and said at least one plate for storing said at least one inflatable bladder and said at least one plate in said deflated state. 27. The article of footwear of claim 15, wherein said sole has an opening for a manifold. 28. An article of footwear comprising: an upper; and a sole comprising: at least one inflatable bladder, wherein said at least one inflatable bladder has an inflated state and a deflated state; a ground engaging surface of said sole has a first profile in said deflated state and a second profile in said inflated state, wherein said first profile is different from said second profile; and an opening in a top surface; a manifold located in said opening in said top surface of said sole, wherein said at least one inflatable bladder is fluidly connected to said manifold; and an underfoot pump fluidly connected to said manifold that sends air through said manifold and into said at least one inflatable bladder for inflating said at least one inflatable bladder. 29. The article of footwear of claim 28, further comprising: a pressure regulator. 30.
