Hi, Just wondering if anyone had experienced any foot problems after using the Yonex SHB-92 or any other Yonex shoes? I've been using Yonex shoes for many years but last year, I've decided to purchase the SHB-92. Since then, my left foot has been giving me painful experience. Pain is on my ball of my foot. Why my left foot? I'm right footed, so I pushed off with my left foot. Any comments or similar experienced? I wonder if I can get a refund or exchange for a different model?
