The fit for men seems a little snug.I wear a shoe size men's 9 and ordered the sock size "large" (shoe size 9-11).I found them to be ok but a bit tight at first, but may work out well with wash and wear typical stretching.
Pros
Second purchase of these socks and t-shirts. Good fit, good quality and good price.
Cons
The cushioning and thick material of the socks may make them less breathable and cause feet to overheat during exercise
