Ultimax socks dont just wick away moisture, they actually channel perspiration and moisture up and out of your footwear, where it can evaporate quickly. These Socks feature blends of X20 acrylic and olefin technologies made to accommodate your feet. Full terry cushioning throughout combines with thin terry soles for superior cushioning without bulk. Toe seams have smooth loops to reduce friction and blistering. Terry-ribbed legs with spandex provide support and hold the sock in place. Anatomically formed Y-heel pockets offer an all-around better fit. Designed for year-round comfort and moisture control. 45% X20 acrylic, 30% olefin, 20% stretch nylon, 5% Lycra. Made in USA.
