To use these socks, simply put them on like you would any other pair of socks. They're great for all kinds of athletic activities or just everyday wear. As for care, it's best to machine - wash them in cold water and tumble - dry on low. Avoid using bleach as it can damage the wool. Don't iron them either, as high heat can shrink the socks. When not in use, store them in a cool, dry place. This will keep them in good condition and make them last longer.
