What is claimed is: 1. An article of footwear, comprising: a sole; an upper attached to said sole, said upper having an inflatable bladder and a ventilation system formed between two sheets of thermoplastic material sealed together along a peripheral weld line, wherein said inflatable bladder and wherein said ventilation system are separately defined by interior weld lines and said ventilation system includes an interior passageway between the two sheets of thermoplastic material defined by the interior weld lines and a plurality of perforations in one of said two sheets of thermoplastic material; and an inflation mechanism fluidly connected to said ventilation system via an interior passageway defined by the interior weld lines such that fluid flows through the interior passageway and through said plurality of perforations into an interior of the article of footwear. 2. The article of footwear of claim 1, wherein said inflation mechanism is operated by the downward pressure of a wearer's foot. 3. The article of footwear of claim 1, wherein said inflation mechanism is fluidly connected to both said inflatable bladder and said ventilation system. 4. The article of footwear of claim 1, wherein a first inflation mechanism is fluidly connected to said inflatable bladder and a second inflation mechanism is fluidly connected to said ventilation system. 5. The article of footwear of claim 4, wherein said first inflation mechanism is in a heel portion of said article of footwear and said second inflation mechanism is in a forefoot portion of said article of footwear. 6. The article of footwear of claim 4, wherein both said first and second inflation mechanisms are disposed in a heel portion of said article of footwear. 7. The article of footwear of claim 6, wherein said first and second inflation mechanisms are disposed horizontally parallel to one another. 8. The article of footwear of claim 6, wherein said first and second inflation mechanisms are disposed vertically parallel to one another. 9. The article of footwear of claim 1, wherein said ventilation system and said inflatable bladder are monolithic. 10. The article of footwear of claim 9, wherein said fluid system and said inflation mechanism are monolithic. 11. The article of footwear of claim 1, wherein at least a portion of said fluid system structure forms an exterior surface of said article of footwear. 12. The article of footwear of claim 1, wherein said inflation mechanism includes a regulator valve. 13. The article of footwear of claim 1, wherein said inflation mechanism includes a pressure sensitive diverter valve. 14. An article of footwear, comprising: a sole; an upper attached to said sole, said upper having an inflatable bladder and a ventilation system formed from two sheets of thermoplastic material sealed together along a peripheral weld line, wherein said inflatable bladder and said ventilation system are separately defined by interior weld lines and wherein said ventilation system includes an interior passageway defined by the interior weld lines and a plurality of perforations in one of said two sheets of thermoplastic material; an inflation mechanism operated by the downward pressure of a wearer's foot, wherein said inflation mechanism includes a fluid inlet and a first fluid outlet fluidly connected to said inflatable bladder with a first valve allowing fluid to flow from said inflation mechanism to said inflatable bladder and restricting fluid from flowing from said inflatable bladder to said inflation mechanism and a second fluid outlet fluidly connected to said ventilation mechanism with a second valve allowing fluid to flow from said inflation mechanism to said ventilation system and restricting fluid from flowing from said ventilation system to said inflation mechanism, wherein said first valve is actuated at a lower pressure than said second valve.
