No one gives a shit about socks past OCS. I’d recommend a nice pair of wool boot socks. Your feet are in those boots for 12+ hrs regularly. Don’t wear 12 for $5 cotton socks.I have a tangential question about the sore subject of socks. The flight suit regs say that socks must be white or green 100% cotton or 100% wool which I assume is for burn prevention in case of cockpit fire. I can't find 100% anything these days besides BS which is in high supply, do you senior winged gentlemen think it's an issue?
