The full-length Air Zoom Strobel unit is stitched directly to the upper. It helps cut unnecessary weight and provides full-foot responsiveness. Full-length foam adds a soft, comfortable sensation and gives back optimal energy for lasting performance. The combination upgrades the underfoot sensation with a softer, more responsive ride. The lightweight structure wraps the foot, so the upper works in harmony with the propulsion system. Multilayered breathable fabric in the upper is lightweight and provides a broken-in feel. It makes for a comfortable, breathable fit that helps you stay cool. Added thickness in strategic areas helps to keep your foot in place by reducing small movements, so you can check into the game and hit the hardwood running. Grooves and ridges in the sole help provide multidirectional traction and court feel. A supportive piece under the arch helps keep the shoe stable. The heel is crafted in a way to help lock in and add support to your Achilles tendon.
