How do they protect your foot during a run?

Protection comes from the construction, not the thickness. The ergonomic left/right knitting follows the anatomy of the foot and eliminates bunching at the base of the toes — the primary cause of blisters. Exposed areas in trail running are reinforced in a targeted manner depending on the model: heel, toe cap, ankles and Achilles tendon.

Do they stay in place without bunching or slipping?

Yes. The elastic construction holds the sock snugly against the foot without compressing it, for consistent support from the first to the last kilometre. Combined with left/right-specific knitting, it prevents slipping inside the shoe and the formation of folds. The sock moves with the foot rather than over it.

Will my feet overheat during long efforts?

No. Merino wool regulates temperature according to effort intensity and absorbs moisture without ever feeling wet. It remains naturally antibacterial and odour-resistant.

How do they prevent blisters?

A blister almost always comes from the same mechanism: a fold forms in the sock, followed by repeated friction at that point. Ergonomic right-foot / left-foot knitting eliminates folds from the construction stage, especially at the base of the toes. The elastic construction then prevents any slipping inside the shoe: the sock follows the foot instead of moving over it. The most exposed areas — heel, toe, ankle bones and Achilles tendon — also receive targeted reinforcement depending on the model.

Who did we design them for?

For trail runners looking for the comfort of wool without the weight, in low-cut shoes.

Long or warm runs where the natural thermoregulation of merino makes the difference between cool feet and overheating.

Those prone to sweaty feet who want a durable odour-resistant solution with no sprays or chemical treatments.

How to wear them?

Merino stays comfortable on dry trails and in cool conditions.

If you are between two sizes, go for the smaller size to avoid folds that can cause blisters.

What sets them apart?

Its blend of merino wool + synthetic fibres naturally thermoregulates your feet in low-cut trail shoes, resisting odours without chemical treatments, at just 25g.

Trail running

Advanced thermoregulation.

Out on the trail, heat builds up fast. Synthetics wick away moisture, but don't regulate temperature. Cotton absorbs sweat, but won't dry. And traditional wool? Too thick, too heavy.

These socks deliver the natural temperature regulation of merino. The wool maintains a stable temperature adapted to your effort level, absorbs moisture without feeling damp, and stays naturally odour-resistant without chemical treatments that wash out.

Anatomical right/left foot shaping places the terry cushioning exactly where your foot needs it, preventing the bunching that causes blisters.

Because a low-cut shoe deserves a sock engineered with equal precision.

In summary This content is written by AI

Customers especially appreciate their comfort: many find them lightweight, pleasant to wear and so unobtrusive that they barely feel them while running. They stay securely in place, with good reinforcement, effective moisture management and appreciated breathability. Several customers use them for trail running or road running, including to protect sensitive feet from blisters; one customer covered 60 to 90 km on a trail without any problems. They are particularly well suited to running and trail outings.

I wasn't familiar with them. They're perfect. They come up high enough so that the top of the shoe's heel doesn't touch the skin, preventing blisters. A problem I've had with other socks.

Perfect! Finally, stockings that I (very sensitive) don't have to wear on my left foot because of the seams?
