Abstract: An article of footwear includes an upper and a sole coupled to the upper. The sole includes an upper sole and a plurality of fluid filled bladder modules coupled to a bottom surface of the upper sole. The plurality of fluid-filled bladder modules include a first bladder module disposed in a first region of the sole and a second bladder module disposed in the first region of the sole, where the second bladder module is spatially separated in a transverse direction from the first bladder module and the first and second bladder modules do not extend into a second region of the sole. The first and second bladder modules are each fluidly isolated from remaining bladder modules. The first and second bladder modules are each asymmetrical. The first bladder module is reflectively symmetrical with respect to the second bladder module.

Abstract: An upper comprising a flexible layer configured to receive a foot, a bladder coupled to an outer surface of the flexible layer, and an inflation mechanism operatively coupled to the bladder for inflating the bladder such that the flexible layer is drawn toward the foot. The bladder extends from a lateral side in a heel region across a throat region to a medial side in the heel region. The bladder comprises a plurality of fluidly connected segments, each segment forming an angle with an adjacent segment.
