I got these boots to wear to and from work here in Ohio during yucky weather days whether it be rain and or snow, I read reviews on Crocs site stating that they were lined boots and could become kind of hot- so they are better on colder damp days- which is what I was looking for a tall, warmer boot but not necessarily a snow boot.
However, when I got these boots there really isn't any lining- the shaft of the boot has a very, very thin cloth lining but the actual foot bed has none. So they are not warm at all and not what I was looking for. As just a rain boot during warmer weather they would be great- very comfortable and fit very nice (I am a 6 1/2 but ordered a 7) just not what I needed.
I did return only because I was really looking for something with a little more warmth to them
