I recently replaced my winter boots with a pair of Sorel Conquest pac boots. I use them for snowshoeing and snow camping. So far they have been great. On my last trip to Twin Lakes, Oregon (near Mt. Hood), it was in the single digits and the boots kept my usually cold feet warm. The provide plenty of support when snowshoeing. They froze solid during the night, but warmed up quickly in the morning after I put them on and walked around a bit.
