Explore the Award-Winning TEKO eco HIKE Collection

Precision-crafted in Italy using 100% renewable energy, our sustainable socks are engineered for everything from bagging Munros in the Highlands to daily outdoor wear. TEKO delivers an uncompromising, blister-free "Responsible Interface" for walkers and trekkers who refuse to compromise on performance or the planet.

Engineered for the Hills

The latest evolution of the eco HIKE range features our proprietary Triaxial FitSystem™. This innovative, three-point anatomical lockdown wraps the contours of your foot to ensure a secure, zero-slip fit—eliminating the internal friction that causes blisters. Combined with a seamless toe and ergonomic left/right specific construction, it provides a perfect second-skin feel in heavy mountaineering boots and walking shoes alike.

Certified Merino Performance

Every pair is built using premium, Mulesing-free and chlorine-free Merino wool that is Bluesign® certified for environmental safety, offering natural temperature regulation and permanent odour resistance. The collection is structurally optimised across five distinct cushioning levels—from our ultralight 1.0 running liners to our maximum-loft 5.0 Expedition socks trusted by professional mountain guides down to -30°C.

Performance with Purpose

As a proud 1% for the Planet business, TEKO dedicates 1% of all annual revenue directly to environmental restoration and protecting our wild spaces. Backed by the iconic TEKO Lifetime Guarantee against manufacturing faults, this collection is the ultimate investment in your outdoor kit.
