I'm XLG in Assos. 6'3', 199 pounds, size 13 (48) shoes. Most Assos socks do not fit me and these do. I like how they feel during the ride, so far in the mid-40's, and using toe covers. Because I have massive calves, and some swelling during rides, some socks will cut into me. These did not cut into me and cut off circulation. I'm ordering a second pair.
