The upper part of the Nike Attero features high quality leather with many perforations that allow air-flow. The cushioning is provided by the combination of full-length Phylon midsole and Zoom Air unit in the forefoot. Above combination gives a stable from heel to toe and offers tons of responsiveness. The shoe fits nicely to the foot after lacing up, holding it in one safe place. The outsole’s pattern allows quick movement on the court with no slippage.
