Darn Tough Women's Mirnavated Micro Crew Ultra-Lightweight Running Socks

Ultralight Merino Performance for Every Mile

Best For: Women's trail running, road running, and endurance training when you want a lightweight, low-bulk sock with targeted underfoot cushioning.

Lightweight without compromise. The Darn Tough Women's Mirnavated Micro Crew Running Socks are built for runners who prefer a close, low-bulk fit. Their ultra-lightweight construction helps minimise excess material, while merino wool naturally manages moisture and helps regulate temperature through changing conditions.

Cushion where needed. Targeted terry-loop cushioning underfoot adds comfort without turning the sock into a bulky layer. A performance fit, integrated arch support, and True Seamless Toe construction help reduce slipping, bunching, and distracting seam friction over long runs.

Run with a purpose. Inspired by athlete Mirna Valerio, this sock connects technical running performance with a broader mission: sales support Come Alive Outside, a non-profit encouraging people to connect with nature. Darn Tough also backs its socks with an unconditional lifetime guarantee.
