FoxRiver Women's Fatigue Fighter Over-The-Calf Ultra-Lightweight Socks 100% Other Fibers Made in US PHENOMENAL COMFORT: Made from super soft filament nylon to stand up to long-term wear; Wick Dry technology helps keep you comfortable and dry all day long; no-rub, irritation-free toe seam is gentle on the toes INCREASED CIRCULATION: Heavier gauge elastic is layed into the sock during the knitting process which provides a tighter fit along the leg from the calf to the ankle, compressing the veins and thereby increasing blood flow FORGET THE ODOR: Scentry helps permanently defend your socks from odor. Natural and man-made agents make this technology a sure way to be confident about sock odor. This is accomplished by an embedded fiber like silver or copper or with a micropolymer silane technology which slows wear and reduces odor in the sock FEEL BETTER AND RECOVER FASTER: 8-15mmHg graduated compression helps reduce swelling or pooling in the foot leading faster recovery times and less pain BACKED BY COMPANY STANDARDS OF EXCELLENCE: Fox River products are guaranteed against manufacturing defects for one year; products may be returned within one year with the dated receipt to the store where you purchased them or by following our FoxSox.com return process
