The Air Force 1 Flyknit Low 2.0 'College Navy' lightens up the classic AF1 silhouette by replacing the model's usual leather upper with stretchy, lightweight Flyknit material. This version comes in a heathered blue, with the midfoot Swoosh, eyestays and heel tab all in a more traditional nubuck. A cored-out midsole doubles as the outsole, also reducing weight, and uses Nike Air technology for a cushioned step.
