Cable Tightening System For An Article of Footwear

摘要

A tightening system for an article of footwear includes a cable disposed between an upper and a sole plate. The upper includes a flexible main body and an exoskeleton covering a portion of the flexible main body in an instep region. The cable is attached to the exoskeleton so that the exoskeleton is tightened to a wearer's foot when the cable length is effectively shortened and/or if the cable tension is increased. The instep region is devoid of the tightening system so that a smooth instep region is provided.
