they're definitely bigger, I'm a size 10, ordered these in 9.5, gonna have to order a 9 and return these. i have 2 pairs of danners and I'm a 9.5 in both of them. so these definitely run big. great boot though, you can feel the quality and the leather is darker then it appears in the picture, which i like. only took away a star cause of the hassle of returning it and ordering a new size. ill be using these boots for year round, including traveling and so on.
