Impact Brake System Mountain Running

The innovative system is applied to the sole to absorb negative ground impact, help traction and improve grip downhill.
Created and developed by the R&D department at La Sportiva, it offers real advantages during racing by reducing negative ground impact. The unique position of the lugs allows as many of them as possible to come into contact with the ground, for maximum impact absorption.

Gore-Tex Extended Comfort

Shoes engineered with GORE-TEX Extended Comfort product technology are designed for indoor and outdoor use in moderate and warmer conditions or during higher activity levels.

They are durably waterproof combined with optimized breathability, offering enduring weather protection. Water stays on the outside while perspiration can easily escape from the inside.

Thanks to their non-insulated construction, they are the ideal solution for people who value outstanding climate comfort and heat release.
