All the sock you need - nothing you don't (with the exception of that cool lil' tab thingy on the back of the sock). The Darn Tough Tab No-Show is an Ultra-Light sock that's perfect for runners and cyclists who know less is more. True Seamless construction reduces hotspots and blisters. Ultra high stitch count creates a super comfortable sock with a streamlined fit like no other. No slipping, no bunching, no blisters. 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 laying down the miles. Still made in Vermont. Guaranteed for life.
