I wear a 9.5 but I usually get boots in a 10. These are 10WW so they are big to me. I am debating to see if I am gonna send them back, I got the brown ones but they have the black ones in my size (since they run so big). This is the 2nd pair of boots I got of this brand and returned. I recommend trying them if you wish, the quality seems ok. Its just that the sizing seems to be more complex than necessary.
