In width, these shoes are SNAR. I don't think I have a wide fit but these shoes are the slimmest shoes I own. I usually use a size 9US for every shoe I have and 90% fit well but for this shoe I would really like Reebok to make it wider because it's really good but after a few hours of use it died out of mine feet. However, I don't know if they will "break" over time (I would love to), but I rarely use them as they are so uncomfortably tight.
