These women's Shetland crew socks are perfect for various weather. Wear them when it's cool or cold. Put them on like any regular socks, and enjoy the snug fit. When it's time to clean them, turn them inside-out and use cold water on a gentle cycle in the washing machine. Don't use bleach. You can either tumble dry on low or hang them to dry. Never dry clean them. If you find these socks aren't as long-lasting as expected, you can return them for a new pair as they come with a lifetime guarantee.
