Darn Tough Women's Circuit Micro Crew Ultra-Lightweight Running Socks are just what you need for active days. These socks are thin and lightweight, so you'll barely notice that they're there, but cushioning underfoot provides added comfort and a bit of support. The material uses merino wool for breathability and moisture wicking so your feet stay cool and dry even during your most intense workouts. Thanks to the performance fit, they won't bunch, slip or cause blisters. The colorful design is fun and stylish.
