I only bought them at first because I could return them for free if they didn't fit. I am a girl but for men I wear a size 10. None of these shoes were marked as wide but one of the comments said they stretched well. I bought size 10. They are really stretchy and don't feel too tight. I run on the treadmill and after a mile my index toe goes numb but I think that's because I've only walked on it twice. In general, I like them very much
