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.
