Well after trying to hunt this past weekend, feel like temp was around zero degrees at daybreak, I need some suggestions on keeping my feet warm. Most of my hunts are perch up in a tree. I wore a pair of smartwool socks under a pair of homemade wool socks with LaCrosse 1600 pac boots. My toes were about numb in 1 hour. I have tried about every combination of socks from my sock drawer. A single pair of wool socks, a double pair of wool socks, a cotten pair with wool socks, a pair of silk socks with wool socks, a pair of liner socks which are suppose to help feet not sweat ( can't remember the name of them ) with wool socks. Nothing seems to help. I know its cold out but my feet get cold even in low 20 degree weather. Maybe I just need better boots. Any suggestions???
