TEKO eco HIKE 3.0 Exodus Triaxial Merino Wool Hiking Socks - Medium Full Cushion (2026 edition)

Brand: TEKO | Model: Exodus Triaxial | Cushioning: 3.0 | Collection: eco HIKE

The TEKO eco HIKE Exodus Triaxial 3.0 Merino Wool Hiking Socks are built for Britain's most demanding terrain — from the granite ridges of the Scottish Highlands to the boggy passes of the Lake District and the gritstone edges of the Peak District. The revolutionary TRIAXIAL FitSystem™ locks the sock onto your foot in three directions simultaneously, eliminating slippage and bunching mile after mile. This is a sock engineered for multi-day expeditions without compromise.

Constructed with Merino Syn3rgy™ yarn — a blend of mulesing-free merino wool and recycled polyester — the Exodus 3.0 wicks faster, dries quicker, and outlasts traditional merino. Natural temperature regulation and odour resistance keep feet comfortable from the first ascent to the final descent. Processed chlorine-free to Bluesign® standards and OEKO-TEX® Standard 100 certified, the sock is crafted in a solar-powered Italian factory using renewable energy and backed by a lifetime guarantee.

Anatomically shaped left/right construction, a seamless toe closure, and the Anti-Crumple Zone work together to virtually eliminate blisters, even with a fully loaded pack across consecutive days on trail. Medium Full Cushioning 3.0 delivers all-season comfort and protection across long, challenging routes — making the Exodus 3.0 the definitive choice for serious hikers throughout the United Kingdom.

Frequently Asked Questions

What makes the TEKO Exodus Triaxial 3.0 different from other merino hiking socks?

The Exodus 3.0 features TEKO's exclusive TRIAXIAL FitSystem™ — a proprietary knitting technology that secures the sock in three directions simultaneously, preventing the slippage and bunching that causes blisters on long-distance trails. Combined with Merino Syn3rgy™ yarn (a blend of mulesing-free merino and recycled polyester), the Exodus dries faster and lasts significantly longer than traditional merino socks. It is also crafted in a solar-powered Italian factory to Bluesign® and OEKO-TEX® Standard 100 standards, and backed by a lifetime guarantee.

Are these socks suitable for multi-day hiking and backpacking?

Absolutely. The Exodus 3.0 is specifically engineered for multi-day expeditions. Medium Full Cushioning 3.0 provides all-day protection on demanding terrain, while the anatomical left/right construction, seamless toe, and Anti-Crumple Zone work together to prevent blisters even when carrying a heavy pack across consecutive days on trail.

How do I choose the right size?

TEKO uses gender-neutral sizing across four sizes. Small fits UK 2–4.5, Medium fits UK 5–7.5, Large fits UK 8–10.5, and X-Large fits UK 11–13.5. If you are between sizes, we recommend sizing up for a more comfortable fit.

How should I care for the TEKO Exodus Triaxial 3.0 to maximise their lifespan?

Machine or hand wash at 30°C and air dry — avoid tumble drying where possible, as high heat can degrade merino fibres over time. The chlorine-free Bluesign® certified wool treatment means these socks maintain their shape and softness wash after wash. With proper care, and backed by TEKO's lifetime guarantee against manufacturing faults, these socks are built to last for years of serious hiking.

What does the TRIAXIAL FitSystem™ actually do?

The TRIAXIAL FitSystem™ is TEKO's proprietary knitting technology that locks the sock onto the foot and lower leg in three directions simultaneously — lengthwise, widthwise, and diagonally. This prevents the sock from shifting, slipping, or bunching during movement, which is the primary cause of blisters and discomfort on long hikes. The triaxial structure also helps accelerate moisture evaporation through the cuff, keeping feet drier during intense activity.

Are TEKO socks genuinely sustainable?

Yes. TEKO's commitment to sustainability is embedded throughout the Exodus 3.0. The sock uses mulesing-free merino wool and incorporates recycled polyester and recycled polyamide in its construction. It is processed without chlorine to Bluesign® standards and holds OEKO-TEX® Standard 100 certification, ensuring no harmful substances are present. Manufacturing takes place in a solar-powered Italian factory using renewable energy, and the sock is backed by a lifetime guarantee — designed to last rather than be replaced.
