Kenetrek Grizzly's for me as well. I usually wear a pair of medium weight wool sock along with a sock liner. I'm just not a fan of heavy wool socks. Tested them again this year on a SD deer hunt. On the 3rd day of the hunt it was 8 degrees with 25 mph winds and 4 inches of snow. While I can't say me feet were warm and toasty, they never got too cold.
