Traveling usually means long days, a lot of it on your feet. Moisture and discomfort on your feet are the surest way I know of to make a day worse than it is. Thus, when I know I’m having a long day, I opt for wool socks that are weather appropriate. These keep my feet dry and breathe really well so that I don’t get blisters even if I walk miles through airports or up the side of a mountain. Good socks are an absolute must, and cotton holds too much moisture for my liking.
