Who did we design them for?

For trail runners and hikers who want ankle coverage without weighing down their feet, on outings where the terrain and weather change.

How warm are they?

Thin and lightweight, they can be worn all year round. Merino wool regulates temperature; in extreme cold, a thicker sock will be more comfortable.

What height?

Mid-calf: the sock covers the ankle and can be worn with low-cut or mid-cut trail and hiking shoes.

What material is it made from?

16% merino wool, with polyamide, recycled polyester, polypropylene and elastane. Merino wool regulates temperature and helps limit odours.

Cover the ankle without adding bulk to the foot

Choosing between a lightweight low-cut sock and a protective high-cut sock is often a compromise. This sock eliminates that trade-off.

Its Caprera yarn (a blend of merino wool and Coolmax®) combines the temperature-regulating properties of both fibres: wool regulates temperature, while Coolmax® wicks away moisture. Feet stay at a steady temperature and dry during exercise.

The mid-cut cuff covers the ankle without adding bulk, while the left- and right-foot-specific fit reduces bunching from the first step.

Because in trail running, you shouldn't have to choose between protection and lightness.

Regulates temperature and wicks away moisture at the same time, keeping feet dry and at the right temperature

Reinforced friction zones

Reinforcements at friction points without adding weight or stiffness to the sock

In summary This content is written by AI

Customers love the comfort, which most find very pleasant, even after a half marathon or over long distances. They also praise the fit and the way the socks stay in place without feeling too thick; several use them regularly for trail running, ultras, hiking or Nordic walking. Their MID height spared one customer from gravel and dust getting into the shoe, while another reported zero blisters. One tip: keep an eye on durability, as several reviews mention possible wear, especially on the forefoot, particularly with the wool.

Comfortable socks, and I especially appreciate the MID height. I only wear these now for mild-season outings. Thanks to them, I no longer have trouble with gravel and dust getting into my old low-cut socks during trail running and hiking.

FAQ

Frequently asked questions

These socks are unisex. Choose your usual shoe size: each size covers three shoe sizes (36/38, 39/41, 42/44 and 45/47).

They help reduce friction: the left- and right-foot design follows the shape of each foot, the friction zones are reinforced, and merino wool manages moisture. A well-fitting shoe matters just as much.

They’re designed to regulate temperature, not add warmth. In the height of summer, how warm they feel depends on your feet, your shoes and the day’s temperature.

The friction zones are reinforced without adding weight to the sock. Like any thin sock, it wears with use: wash it according to the care label to help preserve the fibres.

Yes: you can also wear them for hiking with low-cut or mid-cut shoes. With high-cut hiking boots, a taller sock provides more ankle coverage.

No: they contain 16% merino wool, blended with polyamide, recycled polyester, polypropylene and elastane.

Follow the care instructions on the socks’ label. They release plastic microfibres into the environment when washed.

Yes: they’re suitable for ultra-trail, trail and hiking. Their Caprera merino yarn regulates temperature while wicking away moisture, and high-friction areas are reinforced.
