The best thing I did recently is I started to wear regular cotton socks to the stand. Once I got to the stand I would remove those socks, put them in my pack and replace them with heavy 90% wool socks and my feet typically stay warm. That said, it is a pain in the butt once at the stand, but I would rather have warm feet. As far as boots, I have tried many over the years, anything from rubber boots to 2,400 gram boots and nothing did the trick, until I started switching out my socks. Now this year, I broke my foot and had to find something to put over my broken foot boot and I bought a pair of icebreaker boot blankets. Let me tell you, those things are amazing and others have said above. You throw a hand warmer in there and it is like an oven .
