I lived in the mountains here many years ago and had a pair of these then, now long gone.  They were indispensable for trudging up and down the hills in 2 and 3 feet of snow.  Now that I live on the edge of the Foothills I can get by with shoes or hiking boots but have always wanted something warmer on my feet when having to work outside running the snow blower or going out to the woodpile to feed the wood stove.  These boots are marvelous for those chores.  I bought the Bear rather than the Glacier since I didn't need something that was good to -100F, concerned that my feet would sweat and soak the lining.  Craftsmanship is all around very good, but ask me again in a few years, given the comments of others concerning their being made in China rather than the US.  I wear a mens size 12 and the Sorel 12 was just too big with a single pair of socks, the 11 a perfect fit.  The built in gaiter means my jeans will stay dry and not get soaked to the knees.  Really happy I bought them.
