I ordered these boots to wear over leggings with my long tunics. I ordered a size 9-medium and they are true-to-size and very comfortable.  You can't go wrong with these boots, especially for the money. I paid $32.00 for them total.  They look good. They don't look like "cheap imitations".  They're flat and have a good non-slip sole. I have large calves, but the boots still slide easy on and off.
Again, for the money, you can't go wrong with these boots. I'm very satisfied and I'd purchase another pair if the color I wanted was available.  I would highly recommend, especially if you're on a budget, but still want to look fashionable. Very smart!
