Yonex Power Cushion 03Z Men Shoes absorbs shock then reverses the impact energy for smooth transfer into the next movement. It features round sole which is designed to provide all-around support for quick and smooth footwork. Synchro-fit insole construction creates a secure contact between foot and shoe, reducing energy wastage through an improved fit. The hexagrip pattern provides 3 percent more grip and is 20 percent lighter than standard sole material. Tongue connected with shoe opening reduces overlapping layers for a more snug fit. Asymmetric design with a curved eyelet creates a natural snug fit around the inner arch. Elongating the TPU section reinforces the foot during quick, harsh lateral movements. Upper: P.U. leather, polyester mesh. Outsole: rubber.
