The laces feed through floating wings along the sides. When you tighten the laces, the wings pull down to help hold your foot in place. Full-length Cushlon foam plus a visible Air Zoom Strobel unit provide a dual layer of cushioning that's soft, smooth and responsive. The Air Zoom Strobel eliminates the need for extra layers and brings the energy-returning sensation right up under your foot. Reduced layers throughout the upper strip away unnecessary weight to enhance the the feeling of broken-in comfort. The outsole pattern looks like a topographical map, with an array of contoured ridges that bend and deflect in multiple directions to provide traction for every move. "EASY" is molded into the rubber in a nod to KD's effortless game. Thin overlays help resist abrasion along the toe.
