Alpha Burlys will NOT make it in cold weather. When it gets cold you need true cold weather boots or boot blankets. They're a cheap alternative that does work, although they limit mobility in the stand since they're so bulky. DOn't put them on until you get in the tree. Due to some tissue damage from Vietnam and some vein surjury in later years I have one foot that I have to fight to keep warm even in cool weather. You just have to plan for it.
