This version is made for outdoor court use with its extra-durable rubber outsole. Stick and Groove The 360-degree multidirectional pattern in the outsole is athlete-tested and computer-generated. Smear traction in the forefoot works with grippy rubber that wraps up the sides to help you change direction in an instant. Plush Comfort We coupled a Zoom Air unit in the forefoot with a molded insole for a plush, responsive feel. Forefoot Support Our tunnel-fit lace system gives you 360-degree support in the forefoot when you tie up, which allows you to play any angle or direction without your foot shifting around in the shoe. It’s directly stitched to the forefoot Zoom Air unit and creates a comfortable, snug fit when tightened.
