Technology:

GORE-TEX:
- 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.

FriXion®:
- The La Sportiva FriXion® compound is the result of extensive R&D aimed at creating outsoles with parameters of grip and durability that respond to all types of use and terrain. The Frixion range uses 5 custom formulated compounds from mountain running to climbing shoes.

EVA - INJECTED:
- Highe degree of cushoning and high elasticity of the fabric. These features assist “push off” during the propulsion phase while running, making these models who use injected midsoles, ideal for use on off-road trails. Furthermore, EVA Injected midsole drastically reduce the “squash” effect of the EVA over time, allowing the product to mantain the same features for its entire duration.

- 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.

OrthoLite®:
- The Mountain Running® models use the exclusive eco-friendly La Sportiva insoles by OrthoLite® Hybrid, made using 20% recycled material from the production process. These insoles are designed for both men’s and women’s feet and the thicknesses and materials differ to suit the weight of the average user.
