END TO END ENERGY. Not only is Kevin Durant the game's most lethal scorer, but he's also able to shut down opponents on D as both a perimeter stopper and rim protector. The KD13 takes your game to a new level on both ends of the court with full-length cushioning and an extra forefoot unit. Each work together to provide amazing energy return for every move, all game long. Full-Length, Close-to-Foot Cushioning Stitched directly to the upper, a full-length Nike Air Zoom cushion follows the shape of your foot to give an ultra-responsive sensation and a smooth heel-to-toe transition. Double-Stacked Zoom Air A second Zoom Air unit is stacked underneath the full-length Nike Air Zoom cushion in the forefoot to help enhance explosive movements and amplify energy return. Broken-In Comfort The soft upper is lightweight and flexible. It's constructed from minimal materials to give it a broken-in feel, making it court-ready right out of the box. Visible cutouts in the midsole help provide comfort, enhance flexibility, and let you see the Zoom Air cushioning within. Soft tongue and cushiony collar enhance all-around comfort.
