An article of footwear having a fluid system including an inflatable bladder, an inflation mechanism, and a valve for facilitating air movement through the fluid system. In one embodiment, the valve is an outlet valve between the inflation mechanism and the inflatable bladder that includes an umbrella valve. In another embodiment, the valve is an outlet valve between the inflation mechanism and the inflatable bladder wherein a seating of the outlet valve forms a portion of the inflatable bladder and a portion of an inflation chamber of the inflation mechanism. The seating includes a flange for preventing blocked air flow to the valve. In another embodiment, the valve includes an umbrella valve and an inlet filter for keeping particulates from compromising the umbrella valve.

What is claimed is: 1. An article of footwear, comprising: an inflatable bladder; an inflation mechanism fluidly connected to said inflatable bladder, said inflation mechanism having an inflation chamber and an outlet; and an outlet valve positioned between said outlet of said inflation mechanism and said inflatable bladder, wherein said outlet valve includes an umbrella valve having a seating and a stem, said seating having a first surface defining a portion of said inflation chamber, said first surface having an aperture for receiving said stem and having a flange extending from said first surface for preventing blocked air flow to said inflatable bladder. 2. The article of footwear of claim 1, wherein said inflation chamber of said inflation mechanism is defined by a thermoplastic bulb. 3. The article of footwear of claim 1, wherein said inflation chamber of said inflation mechanism is defined by two thermoplastic sheets. 4. The article of footwear of claim 1, wherein said inflation mechanism includes a foam core. 5. The article of footwear of claim 1, wherein said inflation mechanism is positioned so as to be automatically operated by the downward pressure of a wearer's foot. 6. The article of footwear of claim 1, wherein said inflation mechanism is positioned on an exterior surface of said article of footwear so as to be manually operated by a wearer. 7. The article of footwear of claim 1, wherein said seating further includes a second surface, opposite said first surface, against which a flange of said umbrella valve forms a removable air tight seal. 8. The article of footwear of claim 7, wherein said seating includes at least one flange extending from said second surface. 9. The article of footwear of claim 7, wherein said seating includes at least one intake channel adjacent said stem aperture, wherein said at least one intake channel is under said flange of said umbrella valve. 10. The article of footwear of claim 1, wherein said stem includes at least one stem channel therein providing an air flow pathway through said seating. 11. The article of footwear of claim 7, wherein said second surface of said seating defines an interior surface of said inflatable bladder. 12. The article of footwear of claim 1, further comprising a filter positioned between said inflation chamber of said inflation mechanism and said umbrella valve. 13. The article of footwear of claim 12, wherein said filter does not release particulates. 14. The article of footwear of claim 13, wherein said filter is non-woven. 15. An article of footwear, comprising: an inflatable bladder substantially defined by a first and second sheet of thermoplastic material; an inflation mechanism fluidly connected to said inflatable bladder, said inflation mechanism including an inflation chamber, wherein said inflation chamber is at least partially defined by a third sheet of thermoplastic material; and an outlet valve, said outlet valve including a seating, said seating having a first surface defining a portion of said inflation chamber and a second surface defining a portion of said inflatable bladder, and said seating having an aperture for controlled air movement through said outlet valve and a flange extending from said first surface for preventing blocked air flow to said aperture. 16. The article of footwear of claim 15, wherein said seating includes a first flange extending from said first surface and a second flange extending from said second surface to avoid blocking air flow to said aperture. 17. The article of footwear of claim 15, wherein said outlet valve further includes an umbrella valve positioned within said aperture of said seating. 18. The article of footwear of claim 15, further comprising a filter positioned between said inflation chamber and said aperture, so as to prevent particulates from compromising said controlled air movement. 19. The article of footwear of claim 18, wherein said filter is positioned within an inlet cap, said cap including at least one hole therein for the transfer of air from said inflation chamber of said inflation mechanism to said aperture in said seating of said outlet valve via said filter.
