Our first trail running specific socks. Ergonomically designed for maximum comfort and protection.

Tested by athletes

These high-performance socks are ergonomically designed from sole to shaft, and incorporate support and cushioning to protect your feet even on the most difficult terrain.

Non-slip

Their non-slip technology prevents them from shifting in the shoe, so you can maintain your speed even in the most demanding moments. And thanks to their anti-friction thread and intelligent technology in the sole, they always stay in place. So you advance with firm and secure steps.

Designed to breathe

Made with merino wool, recycled nylon and ribbed mesh that facilitates ventilation, the Merino Ultra Sock socks let your feet breathe, while providing extra support thanks to their cushioned polyamide.
