I love these boots. I've never had warm feet in winter before. I wore them all winter and they still look like new. They're rugged and come up to mid-calf on me (5'5 woman). The one problem I had when I started wearing them was that they chafed my calves; even with socks. I wore them for a while without tying them all the way while indoors and this helped to break them in (or condition my calves - whichever). If these ever wear out, I will definitely buy another pair.
