Whether you are training for a marathon or walking long distances on the weekends, Balega's Blister Resist Quarter Socks protect your feet so blisters don't slow you down. A high tab and extra-deep heel pockets ensure that your sock stays in place, providing for a comfortable fit. The combination of mohair and Drynamix is ideal to keep feet cool and dry. The Drynamix pushes the moisture away from the skin and the mohair has the ability to hold moisture and still keep your feet warm in winter and cool in summer.
