Materials
Made of 51% Merino Wool, 44% Nylon and 5% Lycra® Spandex, these socks combine lightweight comfort with durability, breathability and long-lasting stretch. Each fibre has been selected to maximise running performance while maintaining a secure fit throughout every mile.
Merino Wool
Premium Merino wool naturally regulates temperature, wicks moisture away from the skin and dries quickly to help keep feet cool, dry and comfortable. It also provides natural odour resistance, making the socks ideal for regular training and long-distance running.
Nylon
Nylon reinforces the construction of the socks, improving durability and abrasion resistance while maintaining an ultra-lightweight feel. This helps the socks withstand repeated training sessions without compromising comfort.
Lycra® Spandex
Lycra® Spandex delivers stretch and excellent shape retention, allowing the socks to hug the foot securely. Working with Darn Tough's Performance Fit, it helps eliminate slipping, bunching and unnecessary movement inside your running shoes.
Features & Technologies
Ultra-Lightweight Construction
Darn Tough's lowest-profile yarns create an exceptionally lightweight sock that feels almost like a second skin. The minimal bulk improves comfort while maintaining breathability during high-output activities.
Performance Fit
The Performance Fit wraps securely around the foot to eliminate slipping, bunching and friction that can lead to blisters during long runs.
Blister-Free Running
The combination of Merino wool, seamless construction and a secure anatomical fit helps reduce hotspots and friction, delivering reliable comfort across both road and trail runs.
True Seamless™ Toe
True Seamless™ Toe technology creates an ultra-smooth, virtually undetectable toe seam that helps minimise irritation during repetitive movement.
Targeted Cushioning
Soft terry loop cushioning beneath the foot provides additional rebound and comfort where runners need it most while maintaining the sock's lightweight performance.
Fast Moisture Management
Merino wool quickly moves moisture away from the skin while helping regulate temperature, keeping feet drier and more comfortable throughout your run.
