The Darn Tough Stride Micro Crew Ultra-Lightweight (Style 1043) is a ultra-lightweight merino wool stride micro crew running sock knit at fine gauge from premium merino wool in the brand’s Northfield, Vermont mill. True-seamless construction eliminates the toe seam that causes blisters in lesser socks, and the precision-knit fit holds the sock in place without slipping, bunching, or sliding into the heel.
Use it for road and trail running, where merino wool’s natural moisture-wicking and odor-resistance keep feet dry and comfortable across long days on the trail, road, or jobsite. The fine-gauge knit feels lightweight even at full cushion, and the merino wool regulates temperature year-round — cool in summer, warm in winter.
Darn Tough is family-owned by Cabot Hosiery Mills and has knit socks in Northfield, Vermont since 1978. Every Darn Tough sock is American-made and carries the brand’s unconditional lifetime guarantee — wear them out, send them back, get a new pair, no questions asked.
