I wear an 8.5 wide or a 9. Sometimes I can wear a regular 8.5 if the shoe runs wide. I've enjoyed this style of Clarks in a size 9 and the fit was perfect. BUT I guess those days are gone because I compared this size 9 to one of my older shoes, very similar style size 9 and this shoe is definitely longer which is a deal breaker. Also the top part of the shoe felt stiff and hurt the top of my foot near my toes. Super disappointing since I used to be able to buy any of this type of Clark with no problems. Will return.
