Woollow yak ankle socks keep you cool in summer and warm in winter. They are super soft and comfortable. Our yak socks are hypoallergenic, moisture wicking, odor resistant, made in USA, cruelty free, and lightweight, fitting easily in any shoe. The yaks get a haircut once a year and yarn is made from their fiber. A podiatrist designs our socks for ultimate foot comfort and health. All of our socks are made on our southwestern Pennsylvania farm. Woollow yak socks make a great gift for everyone!
