Boots ran small, order up a whole size.  The ankles were especially small, I had to exchange the first pair for a larger size.  The second pair fit great!  I wear a 9-1/2" wide, ordered a 10 the first time.  Had to go up to an 11 because the seam at the ankle dug into my foot and hurt.  The 11 is only about 1/2" too long in the toe, and socks take most of the excess space anyway.  Very pleased overall.
