I love my Crispi's. I have the Nevadas for the exact type of hunting you are describing. They work well to single digits if moving and about 20-25 degrees or so when mostly still. If it's colder than that and you are still then you will need a warmer boot like a pac boot or something. I wear them up to about70-75 degrees while turkey hunting and my feet do sweat but not ridiculously so. If its warmer than 45-50 degrees in the morning with highs in the 80's or more, I'll opt for a different boot.
I have or have had about 5-6 different Crispi boots. All top quality and really fit my feet well.
