Created and developed by the R&D department at La Sportiva, the Impact Break System offers real advantages by reducing negative ground impact, increasing traction and improving downhill grip. The unique position of the lugs allows as many of them as possible to come into contact with the ground, for maximum shock absorption.

La Sportiva's FriXion compound is the result of extensive R&D aimed at creating outsoles with the optimal balance of grip and durability tailored to specific uses and types of terrain. The Bushido II's FriXion XT V-Groove2 sole incorporates dual-density rubber to deliver superb grip on any type of terrain, dry or wet.

STB Control construction, along with a TPU skeleton placed laterally on the uppers and reaching down to the medial portion of the midsole, stabilizes the shoe. This solution allows a snug fit and greater overall control thanks to the synergistic work of uppers and midsole, as well as reduces the weight of the shoe.
