Light, smooth, strong. With half the wool yarn weight of their cushion socks, Darn Tough's lightweight cushion socks deliver lightweight performance with the perfect amount of cushioning along the base of your foot. Runners and cyclists love its streamlined performance fit while 17.2 micron wool brings home the goods in the comfort department. True Seamless construction assures a smooth fit and reduces blisters and hot spots. No slipping, no bunching, no bull. Fine gauge Merino Wool makes this a fast drying and breathable "all-weather" sock that stays cool in the summer and warm in the winter. And since Merino Wool is naturally antimicrobial this sock repels bacteria and odor when you're putting on the miles. Still made in Vermont. Guaranteed for life.
