Our guarantee: we repair your gear for life

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

Who did we design them for?

For trail and ultra-trail runners looking for the lightest possible high-cut sock without sacrificing durability.

Long, hot runs where breathability is essential and high-friction heel and toe areas must hold up over dozens of kilometres.

For runners who have suffered from blisters on the toes or heel and want targeted reinforcement with zero extra weight.

How to wear them?

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

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

What sets them apart?

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

Reinforced where it matters.

Lightweight performance and durability rarely clash as much as in trail running: the more you strip weight, the faster critical zones wear out. The more you reinforce, the heavier the sock becomes.

These socks solve this paradox through a smart blend of materials. Coolmax® forms the main structure: ultra-light, breathable, actively wicking sweat away. Cordura® reinforces the heel and toe precisely where blisters tend to form on descents.

The result: 30g, full breathability, and targeted durability on the two zones that need it most. Nothing more, nothing less.

Because a good trail sock disappears inside your shoe.

Very good socks. For trail running, I prefer socks that rise slightly like these ones.

Very good sock, very durable, which results in less repairability due to the thickness, but very comfortable for long outings.

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.
