The article of footwear of claim 8, wherein said plurality of fluid conduits are fluidly connected to said first inflatable bladder and, wherein said article of footwear further comprises a secondary fluid conduit having a first end fluidly connected to said first inflatable bladder and a second end fluidly connected to said second inflatable bladder. 11. The article of footwear of claim 8, wherein said plurality of fluid conduits are monolithic with at least one of said first and second inflatable bladders. 12. The article of footwear of claim 6, wherein said plurality of fluid conduits are monolithic with said inflation mechanism. 13. The article of footwear of claim 8, wherein said plurality of fluid conduits are tubing fluidly providing a conduit between at least one of said first and second inflatable bladders and said inflation mechanism. 14. The article of footwear of claim 6, wherein said inflation mechanism is located substantially under the heel of the foot. 15. The article of footwear of claim 6, further comprising a shank, said shank having a plurality of cavities for receiving one or more of said plurality of fluid conduits. 16. An article of footwear comprising: a sole; an upper connected to said sole, wherein a portion of said upper is formed by an inflatable bladder; and an inflation mechanism, wherein said inflation mechanism is disposed in a location which allows operation of said inflation mechanism by downward pressure of a user's foot; and a plurality of fluid conduits, wherein each of said plurality of fluid conduits has a first end directly connected to said inflation mechanism and a second end directly connected to said inflatable bladder. 17. The article of footwear of claim 16, wherein said inflation mechanism includes a channel directly connected to said first end of each of said tubes.
