Thought of that. I have a pair of Lowa Caminos I really like. My feet seem to get cold fast. Moving about, no, but if I have to sit a bit, even with Icebreaker overboots, they cool down quick.

I've never been elk hunting....just sort of figured the 400g of insulation of a "standard" hunting boot is about right. That's what I've used thus far. Just haven't had the demands on my boots that this hunt will entail. And future hunts.....I'm fully intending to keep getting out of the eastern whitetail environment on a regular basis. I love hunting whitetails, but getting to do other stuff is fun.

As for socks, I have a few different weights/brands, but consistent thing in them all is 65% merino wool content or higher or I don't buy the sock. Most of mine are 70-75% merino.
