A full-length Nike Air Zoom cushion follows the shape of your foot and is stitched directly to the upper. It gives an ultra-responsive sensation and a smooth heel-to-toe transition. A second Zoom Air unit is stacked underneath the full-length Nike Air Zoom cushion in the forefoot. It helps enable movements and energy return. Lightweight and flexible, the soft upper is constructed from minimal materials to give it a broken-in feel. This makes it court-ready right out of the box. In the game’s crucial moments, KD thrives. Defenders fear his unstoppable moves and opponents get shut down by his defensive prowess. The KD13 helps him play at an elite level with articulated, full-length cushioning. An extra forefoot unit provides more energy return for every move, all game long.
