Elite athletes know the importance of sock that perform as well as shoes, and our High Performance athletic 2/4 crew socks do just that, thanks to arch support and ankle flex zones, and extra padding in the forefoot, Achilles and heal cup areas. As with all Spun Bamboo® brand socks, we use only the most advanced knitting machines with the highest quality bamboo viscose fiber to produce a truly advanced sock. Once you wear our socks, there will be no doubt you have something special on your feet.
