I bought 3 pairs of these boots. one for each daughter and myself. I read the reviews and went with a 1/2 size up, I am normally a 71/2 and ordered an 8. One daughter has very small feet and hers seem a little big , normally a 6 bought a 7, but she LOVES them. Wore them in the snow and my feet were toasty warm, even without socks. The sole insert comes out, when you pull your foot out , but I love how I can just slip into them easily for a quick run to the car or trash.
