Nike Air Force 1 '07 LX White/University Blue-Black-White Photochromic inks on the upper activate under sunlight, transforming the easy to style all-white upper into a patchwork of vibrant colors that make every step radiant. Silicone Swoosh doubles as an ice cube tray, so you can taste how cool you are. Stitched leather overlays on the upper have a slight sheen and add heritage style, durability and support. Originally designed for performance hoops, Nike Air cushioning brings you lightweight, sport-inspired comfort. Padded, low-cut collar looks sleek and feels great.
