Lurbel Running Stone Pro Four SWS socks: extreme mountain performance
The Lurbel Stone MSWS Pro Four are a technical competition sock designed for skyrunning, developed together with the Merrell Skyrunner World Series 2026. Built for demanding terrain and intense efforts, they offer advanced skin protection, efficient sweat evacuation and mountain-specific cushioning.
- Material: Marine-origin fibers with Regenactiv® and Bmax Tetra technology
- Knitting technology: Regenactiv® + Bmax Tetra + AWC plantar structure
- Breathability: High, with active sweat evacuation through multichannel fiber
Designed for the challenge of skyrunning
These socks have been created to meet the demands of the world skyrunning circuit, where uneven terrain, effort intensity and moisture management are key. Every integrated technology is intended to maximize performance and protect the foot in extreme conditions.
Textile innovation that cares for your skin
Regenactiv® technology acts directly on the skin, helping to maintain an optimal environment against sweat, friction and the proliferation of microorganisms. This is all made possible by the use of marine-origin fibers that provide an extra level of care and performance.
Sweat management at high intensity
The multichannel fiber structure of Bmax Tetra promotes rapid moisture wicking to the outside, keeping the foot dry even in high-temperature conditions and sustained effort.
Cushioning adapted for the mountains
The AWC sole incorporates cushioning waves that absorb impact on uneven terrain, while integrated ventilation channels help dissipate moisture accumulated on the plantar area, improving comfort over long distances.
Ready for international competition
This model is part of a special edition developed together with the Merrell Skyrunner World Series, guaranteeing a design focused on maximum performance in high-level competition.
