Thorlos low-cut tennis socks are designed for maximum shock absorption. Thick cushioning in the ball of foot and heel absorbs shock and help prevent blisters, as extended cushioning over the toes offers maximum protection when you stop and go - great for activities like tennis. Thorlon acrylic fibers, exclusively developed for Thorlos, wick away moisture to keep feet cooler and drier. Contoured heel and toe pockets help eliminate irritation, bunching and slipping. Flat knit at instep offers a better fit. Low-profile toe seam wont rub or irritate your toes.....
