An article of footwear includes an upper and a sole secured thereto. The sole includes a midsole with a receptacle, within which a flexible fluid-filled bladder may be fitted. The bladder is adjustable with respect to the midsole between at least first and second orientations. The bladder provides the sole with a first characteristic when in the first orientation and a second characteristic, different from the first characteristic, when in the second orientation. Accordingly, the sole is readily adjustable between the first characteristic and the second characteristic by movement of the bladder with respect to the midsole. |
