They are durable, waterproof, and surprisingly warm without being heavy and gigantic. I wear them everywhere, not just on the hill.
They are lightweight, very waterproof, and they grip well to the ice. Most of all, I can't get over how warm these boots are. I actually gave away my old gigantic 'sporty' winter boots after trying these.
They look great, and I love that you can wear the liners on their own in the cabin.
What makes them worth it to me, is that they are so versitile. You can wear them to the hill, trekking through the woods, or around town. They have become my everyday boots.
