I purchased these Yonex shoes out of sheer frustration as I was continually getting injured playing badminton using other shoe makes. I must say that this has been the best 50 pounds ever spent. I have used them twice a week for 5 months now and I have been injury free! They also have given me great confidence as they hold you every time you have to lunge for a shot or change direction quickly. Only slight gripe is that the silver has worn away where my trailing foot follows thorough but this is nothing new with Yonex shoes. I am a 8.5 normally and the size 9 I ordered fit perfectly so they are quite a tight fitting shoe which is something to remember. To sum up now when I play I don't even think about what's on my feet. I will be buying them again at this price.
