Went with the kenetrek mountain extreme non insulated. I decided that with the correct sock choice, these boots will work great. When wearing thin, everyday Costco socks, which I would wear with my old boots since the had 600g of insulation, they had a little heel movement. When wearing a medium hunting sock, they felt perfect. Since they are non insulated I will be wearing a thicker sock regardless, and I never felt my feet were to hot in the 600 gram Danners I was used to. Overnighted with amazon prime so I can start breaking them in over the 4th and be ready for some scouting trips!!! I will have the Danners rebuilt this Fall and use them when the temps are really cold.
