Bought these for my wife and she loves them. She normally wears about size 9, so naturally that's what we first ordered. They fit but were a bit too tight. We went up a half size and they fit great! Honestly she said they are the best everyday winter boots she has ever had. And this is coming from the woman that claims she is always cold! Seriously, she is always complaining of cold feet and yet somehow these beasts keep her feet warm. And yet they don't look big and bulky. In fact one of the main criteria for her was they had to be flexible and not feel like a ski boot. Lastly, the zipper down the inside is such a good idea. What else can I say, aside for them running a little small they are perfect. I don't look forward to to day these boots wear out!
