I rated this 4 instead of 5 is because I am a little disappointed. I read other reviews, all of them said nice things about these boots so I expected them to be very good. But compared to my sorel boots (also purchased on Amazon) which are about the same price, these Kamik boots have lower quality and feel less warm. And they DO run small. I normally wear a 6 and I listened to other reviewers and order a 7. They fit perfectly. 6 would be too small. Overally speaking, for the money I paid (about $40), it totally worths buying. But don't expect it to be a perfect warm winter boots.
