Our Warrior anklet Alpaca sock is fashioned from Baby Alpaca Alpacoryarn, the softest of all alpaca. It is made for optimumperformance and developed in the USA.We begin with this dynamic yarn - baby alpaca spun over a tencel core around the finest acrylic micro fiber. The resulting yarn is soft and silky with no itch, only pure natural baby alpaca surrounds the foot, maintaining all the wonderful benefits of alpaca; its thermal insulating properties, moisture wicking, odor control, as well as reducing the ability for foot fungus to propagate. Unlike other alpaca socks, this process creates a silky smooth yarn so that stray hairs will not work out with frequent washing or heavy use. The innovative combination of alpaca fiber and modern technology have created the ultimate performance sock, which assists circulation, perfect for golf, tennis, running or jogging, walking, mountain biking, cycling, working out, Zumba, aerobics, cross training or even working. Just name it, these socks will comfort and protect feet, keeping them the perfect temperature while letting them breathe like no other sock can.
