An adjustable bladder system for an article of footwear is disclosed. The bladder system includes an outer bladder that may be inflated using an external pump. In addition, one or more tensile members may be disposed internally to the outer bladder to provide enhanced support. A valve member may also be disposed internally to the outer bladder. The valve member can include a contoured edge to provide a contoured shape for the outer bladder.

1. A bladder system for an article of footwear, comprising: a sole structure including an outer bladder bounding an interior cavity;wherein the sole structure has a forefoot portion, a heel portion, and a midfoot portion in between the forefoot portion and the heel portion;at least one tensile member disposed inside the interior cavity;a valve member disposed inside the interior cavity, the valve member providing fluid communication between the interior cavity and an exterior of the outer bladder;wherein the valve member is disposed in the midfoot portion of the sole structure and includes: a first surface that is forwardly oriented toward the forefoot portion and that is at a decline toward the forefoot portion,a second surface rearwardly oriented toward the heel portion and facing a sidewall of the at least one tensile member,a third surface that is generally perpendicular to the first surface and the second surface and is on a medial side of the valve member,a fourth surface that is opposite to the third surface, is generally perpendicular to the first surface and the second surface, and is on a lateral side of the valve member, anda fifth surface that is a lower surface that faces in a ground surface direction; andwherein the internal pressure of the outer bladder can be adjusted. 2. The bladder system according to claim 1, wherein the outer bladder includes a first portion disposed in the midfoot portion of the sole structure and a second portion disposed in the heel portion of the sole structure. 3. The bladder system according to claim 2, wherein the first surface of the valve member contacts an upper layer of the outer bladder, and wherein the fifth surface of the valve member contacts a lower layer of the outer bladder,such that the valve member provides structural support to the first portion of the outer bladder. 4. The bladder system according to claim 3, wherein the at least one tensile member provides structural support to the second portion of the outer bladder. 5. The bladder system according to claim 2, wherein the valve member extends from a medial side of the first portion of the outer bladder to a lateral side of the first portion of the outer bladder, and wherein the at least one tensile member is disposed in the second portion of the outer bladder. 6. The bladder system according to claim 2, wherein the outer bladder extends from the heel portion of the sole structure to the forefoot portion of the sole structure; wherein the outer bladder includes a third portion disposed in the forefoot portion of the sole structure;wherein the first portion, the second portion, and the third portion of the outer bladder are in fluid communication;wherein the valve member extends partially across a width of the first portion of the outer bladder, leaving a remaining width of the first portion of the outer bladder; andwherein the at least one tensile member is disposed in the second portion of the outer bladder, in the remaining width of the first portion of the outer bladder adjacent to the valve member, and in the third portion of the outer bladder. 7. The bladder system according to claim 1, wherein the at least one tensile member comprises textile layers that are attached by connecting members. 8. The bladder system according to claim 7, wherein the at least one tensile member is a stacked tensile member comprising a first tensile member and a second tensile member. 9. A bladder system for an article of footwear, comprising: a sole structure including an outer bladder, the outer bladder bounding an interior cavity;the sole structure having a heel portion, a forefoot portion, and a midfoot portion in between the heel portion and the forefoot portion;the outer bladder being substantially deformable;the outer bladder extending from a first portion in a midfoot portion of the sole structure to a second portion in the heel portion of the sole structure;the outer bladder having an upper layer and a lower layer;a valve member disposed inside the interior cavity, the valve member including a valve and a fluid passage that provides fluid communication between the valve and the interior cavity;the valve member including: a contoured surface facing an exterior of the outer bladder in a direction toward the forefoot portion of the sole structure,an inwardly facing surface facing an interior of the outer bladder in a direction toward the heel portion of the sole structure, anda lower surface facing an exterior of the outer bladder in a ground contacting direction;the contoured surface having a height that tapers from an upper edge of the inwardly facing surface down to a forward edge of the lower surface;wherein, at the first portion of the outer bladder, the contoured surface is disposed against the upper layer of the outer bladder and the lower surface is disposed against the lower layer of the outer bladder, such that the upper layer tapers down in a direction toward the forefoot portion to join the lower layer; andwherein the contoured surface of the valve member provides a contoured shape for the first portion of outer bladder. 10. The bladder system according to claim 9, wherein the valve member is made of a substantially more rigid material than the outer bladder. 11. The bladder system according to claim 9, wherein the height of the first portion of the outer bladder decreases non-linearly from a maximum height to approximately zero. 12. The bladder system according to claim 9, wherein the valve member extends from a medial side of the midfoot portion of the sole structure to a lateral side of the midfoot portion of the sole structure. 13. The bladder system according to claim 9, wherein the contoured surface is a convex surface. 14. The bladder system according to claim 9, wherein the height of the valve member decreases non-linearly from a maximum height at the inwardly facing surface to approximately zero at the forward edge of the lower surface. 15. The bladder system according to claim 9, wherein the valve member is a valve plug. 16. The bladder system according to claim 9, further comprising a supporting inner bladder disposed inside the interior cavity of the outer bladder in the second portion of the outer bladder. 17. The bladder system according to claim 16, wherein the supporting inner bladder provides a substantially constant shape for the second portion of the outer bladder and wherein the valve member provides a substantially constant shape for the first portion of the outer bladder. 18. A bladder system for an article of footwear, comprising: a sole structure including an outer bladder bounding an interior cavity;the outer bladder including a first portion and a second portion;at least one support structure disposed inside the interior cavity;a valve member disposed inside the interior cavity, the valve member providing fluid communication between the interior cavity and an exterior of the outer bladder;wherein the at least one support structure provides a substantially constant shape for the second portion of the outer bladder and wherein the valve member provides a substantially constant shape for the first portion of the outer bladder; andwherein the at least one support structure is an inner bladder. 19. The bladder system according to claim 18, wherein the volume of the interior cavity of the outer bladder remains approximately constant as the internal pressure of the outer bladder varies. 20. The bladder system according to claim 18, wherein the internal pressure of the inner bladder is substantially greater than a maximum internal pressure of the outer bladder.
