I wore a pair of Bearpaw all last year throughout the winter in all the snow. They held up and felt good, even wore them in the snow without socks, no problem.
ETA: Only Emu boots are still made in Australia, the others including UGGS are made in China if that makes a difference to you.
As for the Lamo boots they say they use fleece, fleece can be wool from a sheep or it can be made out of polyester like the kind they use in fleece jackets., QVC saying it is fleece lining does not distinguish so if they are made of polyester, not sure how long they would hold up.
Edited: EMU boots on their own website are made in Australia, but as someone else pointed out on a different thread, the EMU boots sold on Evine seem to be coming from China as well.
I'm done with P.C. Just say what you mean and mean what you say. It's easier.
