To use these socks, simply put them on like you would any other pair of socks before going on a hike. They're great for keeping your feet comfortable during long walks. As for care, it's best to wash them in cold water on a gentle cycle. Avoid using harsh detergents as they might damage the wool. When drying, let them air - dry instead of putting them in the dryer, which could shrink the socks. Also, if you notice any loose threads, trim them carefully to keep the socks in good shape.
