I ordered a size 6 and I believe they are true to size, super comfy, and warm! There is a zipper on the side which I wasn't expecting but it doesn't bother me. I'm kind of petite (5'4") and I love the height of the actual boot on my leg as it comes just below my calf. I love this boots and so happy I ordered.

As some people have mentioned there is a bit of weird "new shoe" smell but it quickly went away.
