I bought both the brown and the black of these boots in size 12D. Brown fit fine, but black was one size too large. Go figure. Nice boot, poor sizing. Not very well padded, but good for a light activity day at the office, or similar. One thing that bugs me is the stupid pull tab on the back. It always catches on the hem of my pants, evoking a hillbilliness that I'm not exactly going for. I might have to do some surgery to remove it. Otherwise, nice boot.
