The Darn Tough HikeTrek 14 Sock Cushion was built to withstand the worst conditions the great outdoors can dish out. Legendary performance fit with solid cushioning along the bottom of the foot offers comfort without the bulk. There will be no slipping, no bunching, and no blisters with these socks. The 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. Since Merino Wool is naturally antimicrobial this sock repels bacteria and odor.
