Who did we design them for?

For trail runners who wear low-cut shoes and want a very thin merino wool sock they barely notice from the first kilometre to the last.

How warm are they?

Very thin, they can be worn all year round. Merino wool regulates temperature; in extreme cold, a thicker sock will be more comfortable.

What height?

Low-cut cuff: wear them with low-cut shoes; they do not cover the ankle.

What material is it made from?

15% merino wool, with polyamide, recycled polyester, polypropylene and elastane. Merino wool regulates temperature and helps limit odours.

Low-cut socks that help prevent blisters

Out on the trail, heat builds up fast. Synthetics wick away moisture, but don't regulate temperature. Cotton absorbs sweat, but won't dry. And traditional wool? Too thick, too heavy.

These socks provide the temperature regulation of merino. The wool helps maintain a stable temperature as your effort changes, absorbs moisture without feeling wet and helps limit odours.

Their low-cut cuff goes unnoticed inside a low-cut shoe, while their left- and right-foot shapes fit the foot to reduce the creasing that causes blisters.

Because a low-cut shoe deserves a sock engineered with equal precision.

In summary This content is written by AI

Customers especially appreciate their comfort: most find them very pleasant, lightweight and sometimes so discreet that they hardly feel them. Their slim construction keeps them well adjusted on the foot without friction, including for size 44, and several customers have used them successfully for trail runs of 60 to 90 km or for running. In warm weather, they are considered breathable and help protect fragile feet from blisters. For durability, bear in mind that some customers have not used them long enough to judge, while one already reports early signs of wear.
