Many years ago I found out that, by wearing a thin pair of socks underneath my thick wool socks, my feet were more comfortable- and warmer- than when I just wore thick socks. Hunting, fishing, hiking, any activity applied.

Later, I found out that I was not alone- wearing that thin pair of socks was a common practice among those who were "in the know." Even later, I read articles about this in the hook and bullet press.

Of course, now these socks are known as 'sock liners'. For anyone who is unaware of the benefits offered by wearing sock liners, this might be a timely subject: highland games, and winter, are coming on!
