An article of footwear has an upper and a sole. The sole has an upper sole member, a lower sole member, and at least one inflatable bladder disposed between the upper sole member and the lower sole member. The at least one inflatable bladder has an inflated state and a deflated state. A distance between the upper sole member and the lower sole member is greater in the inflated state than the deflated state. Varying the inflation of the inflatable bladder varies the amount of cushioning in the sole and the thickness of the sole so that the shoe can serve as a multipurpose shoe for activities requiring different amounts of cushioning.

1. A sole for an article of footwear, the sole comprising: a sole member;an outsole comprising an integral, one-piece member having a ground engaging surface and a gap member, wherein the gap member extends from the ground engaging surface and has flexible portion and an end connected to the sole member such that the gap member spans a gap between the sole member and the ground engaging surface, and wherein the flexible portion allows the end to remain connected to the sole member when a size of the gap is changed; andan inflatable bladder positioned between the sole member and the outsole. 2. The sole of claim 1, further comprising a second sole member located between the sole member and the outsole. 3. The sole of claim 2, wherein the inflation and deflation of the inflatable bladder changes the size of the gap. 4. The sole of claim 1, wherein the flexible portion buckles as the size of the gap decreases and the flexible portion straightens as the size of the gap increases. 5. The sole of claim 1, wherein the gap member extends from a medial side of the ground engaging surface. 6. The sole of claim 1, wherein the gap member extends from a lateral side of the ground engaging surface. 7. The sole of claim 1, wherein the gap member extends from a heel portion of the ground engaging surface. 8. The sole of claim 1, wherein the gap member is U-shaped. 9. The sole of claim 1, wherein the gap member is M-shaped. 10. The sole of claim 1, further comprising a plurality of gap members wherein a first gap member extends from a medial side of the ground engaging surface, a second gap member extends from a lateral side of the ground engaging surface, and a third gap member extends from a heel region of the ground engaging surface. 11. The sole of claim 1, wherein the integral, one-piece member has a plurality of gap members extending from the ground engaging surface. 12. An article of footwear comprising: an upper;a sole comprising an outsole comprising an integral, one-piece member having a ground engaging surface and a gap member, wherein the gap member extends from the ground engaging surface and has portion and an end connected to a portion of the article of footwear such that the gap member spans a gap between the portion of the article of footwear and the ground engaging surface, and wherein the flexible portion allows the end to remain connected to the portion of the article of footwear when a size of the gap is changed; and an inflatable bladder positioned between the upper and the outsole. 13. The article of footwear of claim 12 wherein the portion of the article of footwear is the upper. 14.
