With a perforated mesh, croc-print, smooth leather, and patent leather construction, the Nike Air Force 1 Undefeated 5 On It Blue Yellow Croc presents rich fabrication throughout the upper. Undefeated’s tally mark insignia on the heel and woven tongue labels nods to custom AF1s of the early-2000s. From there, exposed foam on the edges of the tongue and a yellowed Air sole adds a vintage appeal.
