What is claimed is: 1. An article of footwear, comprising: a first sheet of elastomeric film and a second sheet of elastomeric film, wherein said first sheet is welded to said second sheet to form an inflation mechanism and an inflatable bladder, wherein said inflation mechanism is monolithic with said inflatable bladder; and a one-way valve, wherein said inflation mechanism is fluidly connected to said inflatable bladder through said one-way valve; wherein said inflation mechanism is positioned so as to be operated by the downward pressure of a wearer's foot. 2. The article of footwear of claim 1, wherein said first sheet and said second sheet are welded along a peripheral edge. 3. The article of footwear of claim 1, wherein an interior weld line separates said inflatable bladder from said inflation mechanism. 4. The article of footwear of claim 1, wherein said one-way valve is formed between two thermoplastic sheets. 5. The article of footwear of claim 1, further comprising an upper, wherein a portion of said inflatable bladder forms a portion of said upper. 6. The article of footwear of claim 1, wherein a portion of said inflatable bladder is disposed under the wearer's foot. 7. The article of footwear of claim 1, wherein said inflation mechanism is positioned so as to be operated by the downward pressure of a wearer's forefoot. 8. The article of footwear of claim 1 wherein said inflation mechanism is positioned so as to be operated by the downward pressure of a wearer's heel. 9. The article of footwear of claim 1, further comprising a second inflation mechanism fluidly connected to said inflatable bladder. 10. The article of footwear of claim 1, further comprising a check valve. 11. The article of footwear of claim 1, further comprising a release valve. 12. The article of footwear of claim 1, further comprising a combination check valve and release valve. 13. The article of footwear of claim 1, wherein said inflation mechanism further comprises a foam core. 14. An article of footwear, comprising: a first sheet of thermoplastic elastomeric film and a second sheet of thermoplastic elastomeric film, wherein said first sheet is welded to said second sheet to form an inflation mechanism and an inflatable bladder, wherein both said inflation mechanism and said inflatable bladder are formed by both said first sheet and said second sheet; an air inlet fluidly connected to said inflation mechanism for introducing ambient air outside of said inflatable bladder to said inflation mechanism; and a valve, wherein said inflation mechanism is fluidly connected to said inflatable bladder through said valve, wherein said valve permits air flow from said inflation mechanism to said inflatable bladder, and wherein said valve limits air flow from said inflatable bladder to said inflation mechanism; wherein said inflation mechanism is positioned so as to be operated by the downward pressure of a wearer's foot. 15. The article of footwear of claim 14, further comprising: a sole, wherein at least a portion of said inflation mechanism is disposed in said sole and at least a portion of said inflatable bladder is disposed in said sole. 16. The article of footwear of claim 15, wherein said sole comprises a foam midsole and wherein at least a portion of said inflation mechanism is disposed in said foam midsole and at least a portion of said inflatable bladder is disposed in said foam midsole. 17. The article of footwear of claim 15, wherein said sole comprises a foam midsole, wherein said foam midsole includes a top surface, and wherein a cavity is formed in said top surface of said foam midsole and a portion of said inflation mechanism is disposed within said cavity. 18. The article of footwear of claim 14, further comprising: a second valve, wherein said air inlet is fluidly connected to said inflation mechanism through said second valve, wherein said second valve permits air flow from said air inlet to said inflation mechanism, and wherein said second valve limits air flow from said inflation mechanism to said air inlet. 19. The article of footwear of claim 18, wherein said air inlet comprises a tube in fluid communication with ambient air outside of said article of footwear and wherein said second valve is fluidly connected to said tube. 20. An article of footwear, comprising: a first sheet of elastomeric film and a second sheet of elastomeric film, wherein said first sheet is sealed to said second sheet to form an inflation mechanism and an inflatable bladder, wherein said inflation mechanism is monolithic with said inflatable bladder; and a one-way valve, wherein said inflation mechanism is fluidly connected to said inflatable bladder through said one-way valve, wherein said inflation mechanism is positioned so as to be operated by the downward pressure of a wearer's foot. 21. The article of footwear of claim 14, wherein said inflation mechanism is monolithic with said inflatable bladder. 22. The article of footwear of claim 20, wherein said first sheet is welded to said second sheet.
