Pro-Line quarter sock for medium-distance trail running.

Designed for technical and medium-distance trail running (recommended for distances up to 50 km), Stone Pro Four socks offer a balanced combination of protection, breathability and support. With a quarter height (H4 – 8 cm above the shoe), they protect the ankle and lower calf without causing overheating.

Dry feet, kilometre after kilometre

Our Bmax Tetra technology combines Regenactiv® fibre, which acts directly on the skin by absorbing sweat and helping keep it dry to minimise irritation and overheating, with a recycled-origin multichannel fibre that quickly evacuates moisture towards the outside. It also features Antiodour Base Layer, providing natural antibacterial and anti-odour action throughout the sock.

Cushioning and protection on uneven terrain

The new AWC Pro Sky plantar structure, with double reinforcement in the heel and toe, provides cushioning and durability on uneven terrain, while ventilation waves help improve the evacuation of heat and moisture.
