My Yonex SHB92’s that I have here with me in China for training. When I came here they werepretty much brand new each pair being used for only about a month. I have beentraining here for 12 days now and this is what has happened alternating betweenshoes each session. Sucks but there getting done, going to have to buy anotherpair or 2 pairs of shoes for the next 3 weeks. These are the left shoes by theway. The right shoes are still in great condition.
