I think I may just get a pair of heavier insulated rubber boots. I have a pair but they are only 400gram thinsulate. Ihad to usemy warmer boots during the late season. The problem is most of my hunting is done near a smallcreek that at times gets too deep for the heavy boots.If I can get a pair with 1000grams or more,my feet will stay warm and I will still be able to cross the creek.
