A thin liner sock, spandex/wool blend for cool weather, or just 100% wool for when it is really cold makes for a warmer foot. This would be under expedition weight smart wool socks, a bit thicker than good quality kilt hose.

What if you put on the soccer socks, and fold them over so they don't show, then put on your kilt hose? Warmer enough?

The two tone cuff idea is intriguing...
