I wear a pair of thin wicking socks under the wool socks, and within my winter boots which are 1/2 size larger than summer boots, I put in the smallest size heatpack, just above my toes. Since the heatpacks only warms up with oxygen exposure, when my feet gets cold, I wiggle my toes to get blood circulation in them and few seconds the heatpacks warms up. The smallest heatpacks usually work for me 6-8 hours, I have yet to leave them in my boots long enough to have the heating effect run out for good. No wires, no electrics.. I buy three dozen of them for $25.00 at the surplus store.
I never had a problem with socks waddingup in my toes..
Master your environment, and you will survive just fine.
Chances favor the prepared mind.
