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 stay dry at high intensity?

Yes — that's what they're built for. Breathable synthetic fibres actively wick moisture away and create ventilation around the foot and ankle, with no heat build-up. The whole thing stays ultra-lightweight so you forget it's there from the very first kilometre.

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 the trail runners and ultra-trail runners who prioritise maximum breathability and lightweight on every outing.

Long and warm outings where heat build-up inside the shoe becomes the primary source of discomfort.

Those who want a high sock with the feel of a low sock.

How to wear them?

Its slim construction fits the volume of any shoe without added bulk.

If you are between two sizes, opt for the smaller size to avoid creasing.

What sets them apart?

Its construction 100% breathable polyamide delivers maximum ventilation on ultra-trails: cool feet at 35g, without ever catching inside the shoe.

Trail running

The high cuff that won't overheat

In trail, a classic high sock traps heat around the ankle. The result: sweat, friction, and blisters on long distances.

These socks were built to prevent that build-up. Their breathable polyamide textile (48% recycled) creates active ventilation around the foot and ankle. At just 35g, it disappears in the shoe from the very first kilometre.

The exceptional hold comes from the elastic construction that hugs the sock without compressing. No bunching. No slipping. A sock that follows the foot — not the other way around.

Because in ultra-trail, comfort starts with your very first piece of kit.

In summary This content is written by AI

Customers particularly appreciate the comfort of these socks: the soft fabric, seams you can barely feel, secure foot support and lack of compression. They also praise their breathability, which makes trail outings more comfortable, as well as their ability to stay in place without slipping. One customer even reports great satisfaction after 70 km trail runs. Durability is still to be confirmed, however: several reviews say it is too early to tell, and one finds them a little thin and fragile. They are especially well suited to trail running.

It's a bit early to comment on durability, but the comfort is definitely there. My husband runs 70km trails and is very happy with the quality.
