The Darn Tough Women’s Run 1/4 Ultra-Lightweight Sock with Cushion (Style 1048) in Sky is a women’s running sock with a light cushion layer along the footbed and a quarter-sock shaft that sits just above the ankle — cut for low-profile running shoe collars. True Seamless toe construction closes the front of the sock smoothly, so there’s no seam bump during long training runs.
Knit with 50% Merino Wool, 45% Nylon, and 5% Lycra Spandex, the sock leans on merino for moisture wicking and temperature regulation through early-morning training runs and afternoon heat. The nylon percentage handles durability against running-mile wear, and the spandex keeps the sock locked on the foot without slipping inside the shoe. Sky is a soft blue colorway that pairs cleanly with women’s running gear.
Darn Tough knits every pair in Northfield, Vermont and backs them with an unconditional lifetime guarantee.
