The Darn Tough Women’s Run 1/4 Ultra-Lightweight Sock with Cushion (Style 1048) in Baltic is a women’s running sock with a light cushion layer along the base of the foot and a quarter-sock height that sits just above the ankle. True Seamless toe construction closes the front of the sock smoothly — no seam rubbing across long-mile training runs.
The merino wool, nylon, and Lycra spandex blend uses merino for moisture wicking and temperature regulation through cold morning runs and warmer afternoon miles, with the nylon percentage handling durability against running-mile wear. The ultra-lightweight profile keeps the foot low inside a performance running shoe, and the spandex percentage keeps the cuff tight around the ankle. Baltic is the deep blue women’s colorway.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
