Article of Footwear with Adjustable Sole

摘要

An article of footwear includes an upper and a sole structure. The sole structure includes a gap extending longitudinally through the sole structure. A tensioning member extends through the sole structure and across the gap such that tensioning the tensioning member contracts the gap and pulls opposing sides of the sole structure together. As the sole structure contracts, the upper is pulled down on the foot, thereby tightening the upper around the foot.
