Merino PerFORM Socks
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.

Technology
Composition: 45% Merino Wool, 25% Acrylic, 25% Polyamide, 5% Spandex.
Merino wool is a natural high-performance fiber that combines warmth, breathability, and moisture control. Its fine fibers provide softness and prevent irritation, while naturally regulating body temperature: retaining heat in cold and releasing moisture during activity.
The blend with technical fibers improves durability, elasticity, and abrasion resistance, creating a versatile, functional fabric for mountain use.
PerFORM
The PerFORM Technology features an anatomically differentiated design for left and right feet. This construction respects the natural shape of the toes, avoiding pressure and enhancing freedom of movement, ideal for barefoot shoes and maximizing comfort during long mountain activities.
