I've been wearing Mucks for quite a while and feet do ok for the most part in the cold with the woody max and a merino wool sock. Contemplating going to a leather boot and saw these on sale (still expensive). They are goretex and have 200 grams insulation. All of the reviews are great but most seem to be using out west doing spot and stalk as opposed to sitting in a tree for hours at a time. Anybody use these and vouch for the feet staying warm? Lot of coin to drop if I see no difference.
