Moisture-wicking Merino Wool prevents blisters and thwarts hotspots before they surface, keeping your feet light and dry.

The right amount of cushioning for extra protection on race day. Added durability for impact comfort on rugged trails.
Green Mountain State of Mind
We take feedback from people running – also biking and working out – all over the country, at least, but Vermont is not a bad place to take notes. Never flat, never climatically predictable, but always a draw to get out. No matter what the weather brings, our socks hit the ground running for all four seasons. Running socks for cold weather, hot weather, mud, rain, slush… you name it. When the weather runs, our socks help make sure you can too.
Choose by Cushion
No Cushion Socks
Ultralight running socks for summer with no cushion help you feel the ground with every foot strike. Thermoregulating and breathable, no cushioning helps you run naturally in hot weather.
Cushion Socks
The cushioned sock option maintains a low profile, adding a bit of absorption and heel padding for extra durability. Hidden comfort and a softer touch make cushioning a staple feature for trail running — and Crossfit.
Choose by Height
No Show Tab Socks
Definitely a study in less-is-more when more miles are certain. The No Show Tab running socks are our lightest creation, with a cushion tab to protect the Achilles in road running shoes.
¼ Socks
Ankle height, quarter length socks sit perfectly still as you dip between the roads and running up trail – the only ankle sock of its kind that can power through tough terrain without slipping.
Micro Crew Socks
Pull them up once and you’re set for miles. The Micro Crew is a worthy running partner that offers lower-leg protection, durability, and yet-to-be-surpassed style for serious runners.
Choose by Weight
Ultra-Lightweight Socks
Ultra-lightweight, breathable, and and knit to fit like a second skin, these are some of the lightest socks we make and undoubtedly the best running socks for hot weather.
Lightweight Socks
Ideal for cooler temperatures, our Lightweight athletic knits are the best cold weather running socks that stay put for miles without ever weighing or slowing you down.

Of course, we like that Mirna Valerio is a Vermonter. She also gives input into our running socks, which we like too. But we also love that Mirna doesn’t care what you think about her. She just smiles and keeps crushing miles in her favorite pair of socks (some of which she helped create). Ultra-runner, public speaker, mother, force of nature… just a few of her talents that had us all ears.
“Darn Tough’s running socks are incredible.” – Mirna
What keeps things warm and keeps things cool is not wildly different – like a thermos. Merino Wool fibers are naturally crimped. That tiny space, combined with an intense ability to absorb and release moisture, keep your feet at an ideal temp, and dry, regardless if you’re running in cold or hot weather.
“In the summertime it feels counterintuitive to want to wear wool socks, but since wool helps with thermoregulation, they actually keep your feet at a perfect temperature, even if they get wet!” – Mirna


Our socks excel at this. Even still, armed with warranty data from our LIFETIME GUARANTEE and runner input, we added reinforcement up the Achilles for extra durability. They’re the best socks for marathon runners and your ideal partner for Sunday long runs and long-distance ultras.
“They are extremely well made and last a long time. They are cute and they make your feet look CLUTCH. And they are made by my local Vermont sock family. What's not to love?” – Mirna
For those who’ve heard the phrase Darn Tight, don’t confuse that with what we call a performance fit – a continual, unrelenting fit with arch support. Reduced sweat, proper temp, and a sleek fit are the equation for a good pair of anti-blister running socks without seams.
“They are technical wool, which is very important to guard against blisters, and to help with heat regulation and cooling. They are appropriately compressive where they need to be, and cushioned where they need to be.” – Mirna
