Swiftwick Aspire Zero Sock

ASPIRE™ features firm compression that hugs the contours of your feet supporting your arch and helping to decrease fatigue, every step, every mile. The compression in higher cuff heights stabilizes leg muscles and boosts circulation, reducing fatigue during extended activity. The thin, breathable design provides maximum ventilation and a barely there feeling, while moisture-wicking Olefin keeps your feet dry and blister-free, so you stay comfortable longer. ZERO TAB (No Show) No show cuff height sits just below the ankle. Our most popular cuff height for running and preferred by many cyclists and golfers. New Micro Tab prevents contact with the back of your shoe to protect your heel.
