Just bought a pair of the Yonex 308's the blue grey colorway. My buddy is a Yonex pro and told me I should give them a try he said you'll play like Wawrinka...after about 30 mins on court i realized i was probebly wearing the best tennis shoe ever. Ok so i wasn't playing like Wawrinka but now I understand why he has improved so much since wearing Yonex!!!!I have always been a loyal vapor guy since way back to the zoom vapors. But after giving these a try i'm on the Yonx bandwagon. I've always used their rackets and was always impressed with the quality and craftsmanship, and shoes are the same. I don't know what more to say they feel just as light as the vapors but with more cushion and they gripped the court like pine tar!!!overall a great shoe no doubt!!! Does anybody else feel the same way?? Yonex forever!!!!
