These socks are easy to use. Just put them on like you would any other pair of socks. They're great for cold - weather activities such as hiking or traveling. When it comes to maintenance, it's best to wash them in cold water. This will help keep the Merino wool and other fibers in good condition. Avoid using harsh detergents as they might damage the fabric. Also, don't tumble - dry them. Instead, let them air - dry. This way, you can enjoy the softness, warmth, and moisture - wicking properties of these socks for a long time.
