Cold weather hunting boots

[58thecat]

Ok the old sorrels pack boots I got in 1990 have a hole in them...they weren't the best but I wore lots of foot layers and I am a cheap ***** but after 27 years of wearing these boots in the cold, be it hunting, fishing, etc it's time to lay down some cash....I need a pair of boots that I can literally sit in -20 for hours on end, need to be water proof too, any real time recommendations?

Thanks.
