The Merino PerFORM Socks are FAST&LIGHT socks designed for mountain activities in cold conditions. Their fabric with 45% merino wool provides natural warmth, moisture management, and a high level of technical comfort. The full terry interior construction delivers insulation and softness, while reinforced areas increase durability in demanding terrain.

The key innovation is the PerFORM Technology: anatomically shaped left and right socks that respect the natural foot morphology without separating the toes, allowing freedom without pressure. An ideal fit for barefoot shoes and for athletes seeking technical comfort during long days in the mountains.

The PerFORM Speedlite Socks are FAST&LIGHT socks designed for high-intensity mountain activities in medium to low temperatures. Their technical blend of polyester, polyamide, and spandex delivers an optimal balance of thermal protection, lightness, and durability.

The shaft features horizontal ventilation channels that enhance breathability and reduce moisture buildup during steep ascents. With quick-drying construction and reinforced soles, they provide consistent comfort during long days in the mountains. PerFORM Technology ensures anatomical left and right design, respecting the natural foot structure for freedom and a precise fit—ideal for skimo, FAST&LIGHT alpinism, or winter trail running.
