I found a pair of like new 307 at goodwill but in size 9 for $25. I wear 10.5. So I tried it on anyway at size 9 and was surprised that it fit, rather snug but it fit. After walking around for about 5 min testing them inthe store I decided to buy them. Could easily walk around in them and later I found out I can even hit in them too. This shows how remarkably comfortable the Yonex shoes are.
Remember reading Rafa wears a super small, snug fitting shoe for his feet as it enables him to feel quicker on the court.
