The Darn Tough Women’s Treeline Micro Crew Midweight Cushion Sock (Style 1971) in Aqua is a women’s micro crew hiking sock with midweight cushion across the full footbed for sustained comfort over trail miles. True Seamless toe construction closes the front of the sock smoothly so there’s no seam bump at the toes during back-to-back trail days.
The merino-nylon-Lycra blend lets the merino percentage handle moisture wicking and temperature regulation across cool mornings and warm afternoons, and the nylon percentage keeps the sock durable against brush contact and repeated boot wear. The micro crew height sits just above the ankle — the standard rise for low-cut hikers and approach shoes. Aqua is a bright blue-green colorway with knit tree-line detailing that brings a lighter note to a gear drawer full of earth tones.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
