For trail runners and ultra-trail runners who want the lightest possible high-upper sock without sacrificing durability.

Long, warm outings where breathability is the priority and where friction zones at the heel and toes need to hold up over dozens of kilometres.

Those who have already had blisters at the toe or heel and are looking for targeted reinforcement without added weight.

The Cordura® heel panel adapts to shoes with high rear friction zones.

If you're between sizes, go down a size to avoid creasing.

The duo Coolmax® + Cordura®: total breathability for dry feet, anti-blister reinforcements at the heel and toe, at only 30g.

Lifetime repair

A repaired garment is a story extended. We ensure the longevity of your Cimalp equipment, season after season.

Reinforced where it counts.

Lightness and durability rarely clash as sharply as in trail: the more you strip weight, the faster the critical zones wear. The more you reinforce, the heavier the sock becomes.

RUN LIGHT solves this paradox through a combination of materials. Coolmax® forms the main structure: ultra-lightweight, breathable, actively wicking sweat away. Cordura® reinforces precisely the heel and toe — exactly where blisters form on descents.

Result: 30g, total breathability, and durability targeted at the two zones that need it most. Nothing more, nothing less.

Because a good trail sock disappears inside the shoe.

FAQ

Frequently asked questions

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.

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.

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.

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.

If you place your order before 1 pm (excluding weekends), it will be dispatched the same day. Allow 2 to 4 working days for home delivery or collection point delivery within mainland France.

Yes, absolutely. You have 30 days to return it and get a refund or an exchange. Return shipping is free. The item must be new, unworn, unwashed, and have its original tag.
