The women’s Lifestyle Ultralight Crew socks were designed to make days on your feet that much better. They're made with a durable blend of merino wool and nylon, with a touch of LYCRA for stretch. Reinforcements in the toes and heels improve durability while seamless toe boxes eliminate bunching and prevent blisters. The merino wool construction makes these socks breathable and naturally resistant to odor while remaining warm and comfortable.
