As some of the reviewers noted, they're a bit narrow, especially in the arch. My feet are M width with low arches, and these cut into the top of my feet. Originally, I bought a half size smaller pair, and the length was fine, but the top was too tight, so I ordered another pair in my regular size, and even though the length is fine, they're still tight in the arch area. But overall, it's a good buy. This seems to be the only brand that makes this type of style out of real leather.
UPDATE: changing my review from 4 to 1 star. After wearing the larger pair for a couple of weeks, I now realize it hasn't stretched much either and is still too tight in the arch area. I can't wear these for longer than an hour and have to take a break for a few days because my arches hurt after wearing these even for an hour.
