An inflatable bladder for use in an article of footwear including a first sheet of a flexible fluid-impervious material and a second sheet of flexible fluid-impervious material. The first sheet and the second sheet are sealed along air-tight weld lines forming at least one narrow channel. The inflatable bladder includes an air passage device for maintaining air flow within the narrow channel. In one embodiment, the first sheet has an embossed interior surface to limit the contact between the first sheet and second sheet. Another embodiment includes the use of a mechanical device to separate the first sheet and the second sheet within a narrow channel. A method of manufacturing an inflatable bladder, a method of increasing localized air flow though a narrow channel of an inflatable bladder for use in an article of footwear and an article of footwear incorporating the inflatable bladder are also described.

What is claimed is: 1. An article of footwear comprising: an upper; a sole attached to said upper; and an inflatable bladder introduced into at least one of said upper and said sole; wherein said inflatable bladder includes a first sheet of a fluid-impervious material having an interior surface and a second sheet of fluid-impervious material having an interior surface, wherein said first sheet and said second sheet are sealed wherein at least a portion of the interior surface of said first sheet is in contact with at least a portion of the interior surface of said second sheet, and wherein substantially all of said first sheet has an embossed interior surface that limits said interior surface contact between said first and second sheets. 2. The article of footwear of claim 1, wherein a portion of said second sheet has an embossed interior surface. 3. The article of footwear of claim 1, wherein at least said first sheet includes a layer of thermoplastic film. 4. The article of footwear of claim 3 wherein at least said first sheet is a laminate of a thermoplastic film and substrate. 5. The article of footwear of claim 4, wherein said substrate is a textile. 6. The article of footwear of claim 5, wherein said substrate is a non-woven nylon and polyethylene blend. 7. The article of footwear of claim 3, wherein said thermoplastic film is selected from the group consisting of polyurethanes, ethylenevinylacetate/polyethylene copolymer; polyester elastomer; ethylenevinylacetate/polypropylene copolymer; polyethylene; polypropylene; neoprene; natural rubber; dacron/polyester; polyvinylchloride; thermoplastic rubbers; nitrile rubber; butyl rubber; sulfide rubber; polyvinyl acetate; methyl rubber; buna N.; buna S.; polystyrene; ethylene propylene; polybutadiene; polypropylene; silicone rubber, chlorsulfonated polyethylene and nylon. 8. The article of footwear of claim 7, wherein said thermoplastic film is selected from a group consisting of a polyester urethane film and a polyether urethane film. 9. An inflatable bladder for use in an article of footwear, comprising: a first sheet of a fluid-impervious material having an interior surface and a second sheet of fluid-impervious material having an interior surface, wherein at least a portion of an interior surface of said first sheet is in contact with at least a portion of the interior surface of said second sheet, wherein said first sheet and said second sheet are sealed and substantially all of said first sheet has an embossed interior surface that limits said interior surface contact between said first and second sheets. 10. The inflatable bladder of claim 9, wherein at least a portion of said second sheet has an embossed interior surface. 11. The inflatable bladder of claim 9, wherein each of said first and second sheets includes a layer of thermoplastic film. 12. The inflatable bladder of claim 11 wherein at least one of said first sheet and said second sheet is a laminate of a thermoplastic film and substrate. 13. The inflatable bladder of claim 12, wherein said substrate is made from a textile. 14. The inflatable bladder of claim 13, wherein said substrate is a non-woven nylon and polyethylene blend. 15. The inflatable bladder of claim 11, wherein said thermoplastic film is selected from the group consisting of polyurethanes, ethylenevinylacetate/polyethylene copolymer; polyester elastomer; ethylenevinylacetate/polypropylene copolymer; polyethylene; polypropylene; neoprene; natural rubber; dacron/polyester; polyvinylchloride; thermoplastic rubbers; nitrile rubber; butyl rubber; sulfide rubber; polyvinyl acetate; methyl rubber; buna N.; buna S.; polystyrene; ethylene propylene; polybutadiene; polypropylene; silicone rubber, chlorsulfonated polyethylene and nylon. 16. The inflatable bladder of claim 15, wherein said thermoplastic film is selected from a group consisting of a polyester urethane film and a polyether urethane film. 17. A method of manufacturing an inflatable bladder for an article of footwear, comprising: providing a first fluid-impervious sheet having an interior surface and a second fluid-impervious sheet having an interior surface, wherein at least a portion of the interior surface of said first sheet is in contact with at least a portion of the interior surface of said second sheet, wherein substantially all of said first sheet includes a first embossed interior surface that limits said interior surface contact between said first and second sheets; positioning said first embossed surface interior surface adjacent to and facing a second interior surface of said second sheet; and sealing said first and second sheets together to form an inflatable bladder. 18. The method of claim 17, wherein at least a portion of said second interior surface is an embossed surface. 19. The method of claim 17, wherein each of said first and second sheets includes a layer of a thermoplastic film. 20. The method of claim 19 wherein at least one of said first sheet and said second sheet is a laminate of a thermoplastic film and substrate. 21. The method of claim 20, wherein said substrate is made from a textile. 22. The method of claim 21, wherein said substrate is a non-woven nylon and polyethylene blend. 23. The method of claim 19, wherein said thermoplastic film is selected from the group consisting of polyurethanes, ethylenevinylacetate/polyethylene copolymer; polyester elastomer; ethylenevinylacetate/polypropylene copolymer; polyethylene; polypropylene; neoprene; natural rubber; dacron/polyester; polyvinylchloride; thermoplastic rubbers; nitrile rubber; butyl rubber; sulfide rubber; polyvinyl acetate; methyl rubber; buna N.; buna S.; polystyrene; ethylene propylene; polybutadiene; polypropylene; silicone rubber, chlorsulfonated polyethylene and nylon. 24. The method of claim 23, wherein said thermoplastic film is selected from a group consisting of a polyester urethane film and a polyether urethane film. 25. An inflatable bladder for use in an article of footwear comprising: a first sheet of a fluid-impervious material having an interior surface; a second sheet of a fluid-impervious material having an interior surface, wherein at least a portion of the interior surface of said first sheet is in contact with at least a portion of the interior surface of said second sheet, wherein said first sheet and said second sheet are sealed; and at least one narrow channel between said first and second sheets, wherein at least a portion of an interior surface of said first sheet along said narrow channel is embossed to limit said interior surface contact between said first and second sheets, wherein a substrate is laminated to a portion of an interior surface of at least said first sheet, and wherein said first sheet includes an embossed thermoplastic film, and wherein said first sheet is a laminate of a thermoplastic film and substrate. 26. A method of increasing localized air flow through a narrow channel of an inflatable bladder for use in an article of footwear, comprising: providing a first fluid-impervious sheet having an interior surface and a second fluid-impervious sheet having an interior surface, wherein at least a portion of the interior surface of said first sheet is in contact with at least a portion of the interior surface of said second sheet; embossing at least a portion of an interior surface of one of said first or second sheets to limit said interior surface contact between said first and second sheets; sealing said first sheet and said second sheet to form an inflatable bladder having at least one narrow channel, wherein said embossed material is a substrate laminated to a portion of an interior surface of at least said first sheet.
