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 seeking versatility: intermediate ankle protection without the bulk of a high-cut design.

Mixed outings with changeable weather or alternating terrain—the mid cut adapts to all conditions.

Anyone torn between low and high cuts who wants an uncompromising middle ground.

How to wear them?

Ideal for outings in unpredictable weather.

If you are between sizes, choose the smaller size to avoid bunching that causes blisters.

What sets them apart?

Its Caprera yarn (merino + Coolmax®) combines natural thermoregulation with active moisture-wicking: the best of both fibres in a mid-cut sock.

Advanced thermoregulation.

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®) delivers the thermoregulating properties of both fibres: wool regulates temperature, while Coolmax® wicks away moisture. Feet stay at a stable temperature, dry during intense effort, and warm when stationary.

The mid-cut cuff covers the ankle without adding weight. Anatomical right/left foot shaping prevents bunching from the very first step.

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

Their thin, lightweight design is often praised, as is their breathability, helping feet stay comfortable during exercise. Several customers use them for trail running, including over long distances, without blisters or rubbing; they also work well for hiking and Nordic walking. One customer especially recommends them for their comfort and low bulk, which keeps the foot feeling light.

I am size UK 12/EU 47 and as with pretty much all socks I do find them too tight. Now, they do stretch to fit my feet but I really wish manufacturers would make socks just a little bit larger. Quality is great though.
