A cushioning member for an article of footwear. The cushioning member is a flexible bladder having a fluidly interconnected heel chamber and forefoot chamber. The bladder is disposed above the sole and beneath the wearer's foot to provided added cushioning to the wearer. The bladder contains air at slightly above ambient pressure and can be formed by thermoforming or by welding two sheets of resilient, flexible material together. A connecting passage fluidly connects the heel chamber and the forefoot chamber. The connecting passage is narrow to control the flow of air between the two chambers.

1. An article of footwear, comprising: a sole having a forefoot portion and a heel portion, said sole comprising a midsole, an intermediate sole, and a ground contacting surface; andan indentation formed in said midsole,wherein a portion of said intermediate sole is disposed in said indentation and a portion of said intermediate sole extends from said midsole and below at least a portion of said ground contacting surface, such that a forefoot bulge extends out from the forefoot portion of said ground contacting surface and a heel bulge extends out from the heel portion of said ground contacting surface. 2. The article of footwear of claim 1, wherein at least half of said intermediate sole extends from said midsole. 3. The article of footwear of claim 1, wherein at least half of said intermediate sole extends from said indentation. 4. The article of footwear of claim 1, wherein at least half of said intermediate sole extends from said midsole in the forefoot portion and the heel portion. 5. The article of footwear of claim 1, wherein said indentation is concave. 6. The article of footwear of claim 1, wherein said intermediate sole comprises a resilient insert. 7. The article of footwear of claim 6, wherein the resilient insert contains air at ambient pressure. 8. The article of footwear of claim 6, wherein the resilient insert comprises at least one forefoot chamber and at least one heel chamber in fluid communication with the at least one forefoot chamber. 9. The article of footwear of claim 6, wherein the resilient insert comprises a plurality of forefoot chambers and a plurality of heel chambers. 10. An article of footwear, comprising: a sole having a forefoot portion and a heel portion, said sole comprising a midsole, an intermediate sole having an intermediate sole forefoot bulge and an intermediate sole heel bulge defining a bottom surface thereof, and an outsole having a ground contacting surface,wherein at least a portion of said intermediate sole is disposed in said midsole and said intermediate sole forefoot bulge and heel bulge extend from said midsole,wherein the outsole conforms to the intermediate sole forefoot bulge and heel bulge to form an outsole forefoot bulge extending from the forefoot portion of said ground contacting surface and an outsole heel bulge extending from the heel portion of said ground contacting surface. 11. The article of footwear of claim 6, further comprising an indentation formed in said midsole. 12. The article of footwear of claim 11, wherein at least a portion of said intermediate sole is disposed in said indentation and at least half of said intermediate sole extends from said indentation. 13. The article of footwear of claim 10, further comprising a cavity formed in said midsole. 14. The article of footwear of claim 13, wherein at least a portion of said intermediate sole is disposed in said cavity and at least half of said intermediate sole extends from said cavity. 15. The article of footwear of claim 10, wherein said intermediate sole comprises a resilient insert. 16. The article of footwear of claim 15, wherein the resilient insert comprises at least one forefoot chamber and at least one heel chamber in fluid communication with the at least one forefoot chamber. 17. The article of footwear of claim 16, wherein the resilient insert comprises a plurality of forefoot chambers and a plurality of heel chambers. 18. An article of footwear, comprising: a sole having a forefoot portion and a heel portion, said sole comprising: a midsole having a concave indentation formed therein,an outsole having a concave indentation formed therein, wherein a periphery of the outsole indentation mates with a periphery of the midsole indentation to define a cavity therebetween,a resilient insert disposed in the cavity, said resilient insert having a forefoot chamber, a heel chamber, and a passageway fluidly connecting the forefoot chamber and the heel chamber, anda ground contacting surface,wherein the forefoot chamber conforms to the shape of the midsole indentation and the outsole indentation to form a forefoot bulge extending from the forefoot portion of said ground contacting surface and wherein the heel chamber conforms to the shape of the midsole indentation and the outsole indentation to form a heel bulge extending from the heel portion of the ground contacting surface. 19. The article of footwear of claim 18, wherein at least half of said resilient insert extends from the midsole indentation. 20. The article of footwear of claim 18, wherein at least half of the forefoot chamber extends from the midsole indentation and at least half of the heel chamber extends from the midsole indentation. 21. The article of footwear of claim 18, wherein the resilient insert contains air at ambient pressure. 22. The article of footwear of claim 18, wherein the forefoot bulge and the heel bulge are convex. 23. The article of footwear of claim 18, wherein said midsole is foam. 24. The article of footwear of claim 18, wherein the midsole indentation curves in a toe-to-heel direction, and wherein the outsole indentation curves in a toe-to-heel direction.
