So I wanted a boot that fit well, was winter-proof, and was comfortable.

I only got two out of three.

When I put them on, I realized there's what seems to be a cardboard insert on top and around the heel that just doesn't give as you move.  It feels a bit like a box.  A box of Crocs.

So, while I like them, I was hoping to get a boot that didn't need breaking in.  I'll give it four stars, but this boot was so close! But alas, no cigar.
