The Winter is a full double boot, warm, light, and sturdy. We worked with both Alico and Intuition to put together this lightest of double backcountry leather boots. This is pretty much the boot I used on most of my winter trips into the Altai Mountains. I had the Alico shell and a bit lower wrap Intuition liner. This setup is quite light for a double leather boot, very warm, and gave me a good balance of touring performance and ski control. My first trip into the Altai I took plastic tele boots and found they got very stiff in really cold weather (leather does not) and the plastic seemed to conduct cold much more efficiently than leather.
