These men's casual socks are perfect for the winter. Simply put them on like you would any other socks. They're thick and warm, made from a great blend of cashmere and rabbit wool. When it comes to washing, use a gentle cycle with cold water and mild detergent. Avoid using bleach as it can damage the wool. After washing, lay them flat to dry to keep their shape. Enjoy the comfort and warmth these socks bring all winter long!
