Thank you for viewing. This is a pair of YONEX Power Cushion 670 badminton shoes. The Power Cushion 670 uses a lightweight shock-absorbing material developed by YONEX. It softens the impact received during landing and converts that energy into the next footwork. Used once a week for just under a year, and then stored at home. Upon taking them out of the shoe box, there are cracks and faint stains (see photo 6) due to aging. This is a model that can be worn for matches. I have set the price low.
