Abstract
An article of footwear includes a sole structure including a polymeric bladder element enclosing a fluid-filled interior cavity. The bladder element has a surface with a groove that extends generally parallel with a transverse edge from a lateral side to a medial side, and has a reduced thickness at the groove. A first length along a longitudinal midline of the bladder element from a longitudinal extremity of the bladder element to the groove corresponds with a first footwear size, and a second length along the longitudinal midline of the bladder element from the longitudinal extremity to the transverse edge corresponds with a second footwear size larger than the first footwear size. The sole structure is used in a method of manufacturing an article of footwear.
