ALL GROUNDS:
Versatile soles, ideal for all types of terrain including stone, scree, grass, moss and mud. Ideal for running either in high humidity or on dry ground. Incorporates the Impact Brake System.

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.

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.

INFINITOO:
Exclusive technology that absorbs the negative impact with the ground and guarantees a never
seen before energy return. The Infinitoo™ midsole mantains its original stretch features unaltered over time.
