Coolmax® Run Quarter Ultra-Lightweight Running Sock

All the performance. None of the wool. The Darn Tough Coolmax® Quarter Running Sock is built for runners who want lightweight breathability, moisture-wicking comfort, and zero distractions—without Merino wool. Whether you’re vegan, allergic, or just prefer synthetic performance, this sock delivers.

With Coolmax® yarns that pull moisture away from the skin, your feet stay cool, dry, and blister-free even on the longest runs. Plush upper ribbing ensures a secure fit, while targeted cushioning and arch support help fight foot fatigue. Flex windows reduce bulk where your foot needs to move most, giving you the freedom to run farther, faster, and more comfortably.

And like all Darn Tough socks, these are proudly knit in Vermont and guaranteed for life—because your socks should never slow you down.
