Organic cotton not only makes these socks "green", but also provides superior softness. Classic design, the turn cuff can be pulled up for a full length crew sock. Spandex is included to add stretch without compromising the lasting shape of the sock. Due to the natural materials use, colors may vary slightly. Fits US shoe sizes 6-9 or sock size 9-11. Please note: Socks are not able to be returned or refunded if they have been removed from their original packaging.
