Our all natural baby alpaca no slip socks are made from 80%baby alpaca, 15%nylon, and 5%spandex. Nylon and spandex are added for increased durability and shape retention. Alpaca is perfect for socks because its extremely soft and warmer than merino wool. Alpaca fibers are hollow, which makes it a better insulator than sheep’s wool. Being knit from a natural fiber, these socks wick away moisture, keeping skin dry and cozy. We also added a no slip bottom- this helps prevent slipping on hardwood or tile floors. As with all our socks, these are made in the sock mill on our Pennsylvania farm. They are designed by a podiatrist to assure you receive the best design for comfort and foot health. Care instructions- Machine or hand wash in cold water, air dry.
