I really like these tennis shoes except for the fact that I had to send the first pair back. I always where an 8 in running/tennis shoes and have countless pairs of ASICS. However, the 8 was way to big for me. Luckily they included a UPS return label and I was able to get a 7 1/2 instead which  fit perfectly!! If you have a wider foot you won't have to worry about them being too big. However, if you have a narrow foot like me I would go a half size down.
