Anybody here have any experience with Hoffman mtn boots? I have a pair of the insulated version. I'm very disappointed I'm them, now they are comfortable to walk in and support good, kept my feet dry, but they aren't very warm. Opening day of deer season last Friday I was sitting for awhile about an hour and meet toes were getting cold. It was proably 40-50 degrees out. I have never had issues with my feet in them temperatures before. I was talking with another guy we hunt with out there and he had kenetreks 1000. His feet get cold easily too in these boots. His thoughts are the nylon plastic shank is getting cold and radiating the cold to our feet. Is this a very well possibility?
