#1 – Never ever wear cotton socks for any kind of serious emergency, disaster or especially “grid-down” situations. Cotton socks may be great for sports, keep it that way. They will tear your feet up under the conditions you will be subjected to during emergency, disaster or “grid-down” situations. When wet, cotton socks will destroy the skin on your feet.
#2 – Never ever wear any polypropylene socks. First off, your feet will really, really stink. Second, your feet will get wet, your skin will break down and your feet will get cold once the sun goes down.
