I love these boots.  I usually wear a size 9.5 to a 10 and I ordered a size 10 thinking I'd be wearing thick warm socks in them.  I probably could've ordered a 9.5, but I have a bunion on my left foot and would rather have a slightly larger toe box to deal with than a cramped foot.  I even wear them to work for 7-9 hours standing at a time.
