“The YONEX Power Cushion SHB Infinity 2 Unisex Badminton Shoes for Men are one of the best badminton shoes with a synthetic upper and synthetic resin midsole. Key Features: Synchro-Fit Insole YONEX’s new Synchro-Fit Insole construction allows a closer fit between shoe and foot, keeping power loss to an absolute minimum to achieve smoother movement and quicker footwork. Compared to conventional footwear, the mid-to-heel area on the insole is lifted to provide a closer fit between the shoe and the foot. Holding the heel more firmly against the insole reduces the gap between the shoe and the foot, improving comfort and ensuring the foot does not slip forwards inside the shoe. 3D Power Graphite Sheet A 3D Power Carbon plate is inserted in the midsole, reducing weight and reinforcing your landing stability. Power Graphite Drive A graphite sheet is inserted along the sole for increased stability and to propel you forward to the next shot. Toe Assist Shape A toe-centric design that cuts down on pressure in the big toe and offers improved support at the mid-foot and heel for a stable fit. Power loss is reduced, allowing for swift footwork. Inner Bootie A knit bootie is integrated into the shoe, replacing the conventional tongue for improved comfort and a better all-around fit. Round Sole The YONEX Round Sole is designed to provide all-around support for quick and smooth footwork. The Round Sole ensures smooth movements and the transfer of maximum energy.” What type of midsole and outsole does the shoe have? These shoes have a synthetic resin midsole and a rubber outsole.
