Which Darn Tough sock should you choose?

Not every trail calls for the same sock. That's why Darn Tough offers different thicknesses and heights.

• Lightweight socks are ideal for fast runs and warmer conditions, such as the 1040 Run Quarter.
• Midweight models offer extra cushioning over long distances, such as the Hiker Micro Crew.
• Crew height gives better protection against branches, stones and dirt on technical trails.
• Micro Crew models combine protection with a compact fit in trail shoes, such as the Light Hiker Micro Crew.

Merino wool: ideal for trails in every season

Merino wool is popular with trail runners because it regulates temperature and stays comfortable, even when your feet get wet. On cold morning runs your feet stay warm, while excess heat is released on hard climbs. Merino also helps limit odour. Handy on multi-day adventures, long races or back-to-back training days.
