The sock is one of the most important parts of the wardrobe from a functional stand-point. One of the few items really created to protect us. It makes sense that, along with underwear, it was one of the first clothing items ever made. Socks are there to help you live without having to think about your feet and their well-being while you try and live like a normal human being. Socks are basically an extra layer of skin between your foot and the world.
