I normally wear size 10 in boots, but some I can go 9.5, depending on the socks worn. With these (size 10), I found they fit best with thick wool socks (fox river). Because of the fit and and the style, these are moving into the rank of favorite boots of all time. The bullhide vamps are more supple than I expected, which makes them feel almost broken in. They look better in person than in any photos. Great service from Carter’s. Boots were well packed and in perfect condition when they arrived.
