A Hiwassee No-Slip Boot Sock in the lightest tech build. Over-the-calf height that won't fall down in neoprene, rubber, western or other loose-calf boots, finishing just at the top of the calf for a secure fit, with a wide welt that won't bind or constrict. Wicking spun polyester body, nylon reinforcement through the heel and toe, and Merino wool cushioning underfoot. Charcoal/Blue. Made in Niota, Tennessee.
