BUY YOUR SIZE! I bought these one size smaller than what I wear because I've heard too many people say the boots run large. No, they do not run large...just a bit wide. I have long skinny foot so with some shoes, I have issues with wideness. But the solution to this problem is either wear thick socks or double up on socks. I returned these boots and bought my regular size, wore them out with double socks and they were fantastic. I walked around a museum the first time wearing them and I did not need to break them in at all.
