I work outside all day. I have found changing socks at lunch or when feet are extremely cold seems to help. I have changed socks after walking to my stand. The dry socks seam to help. Not wearing your boots in the truck will also help keep themn in the cab and warm for sure. I wear crocks when driving to hunt. It works sometimes.
I did pretty much the exact thing last sunday when it was 20degrees and windy as all get out and my normal hiking boots were sufficient for the 2 hours I sat before my kill. Keep them loose and keep dry socks. GO SLOW when hiking to your stand, sweat is the enemy.
