I usually wear an 8.5 shoe/9 boot so  I ordered a 9 and it fits with a thin sock just as I had hoped it would.  Because its suede, it only took two days to break in.  My job requires me to be on my feet all day and this boot works for that.  I love the rugged/worn look.  The lack of buckles or other hardware is a plus--nothing for my pants to get caught on.  The shape of the boot is one that will not go out of style anytime soon.
