Technologies and manufacturing processes

Impact Break System
Innovative system on the sole to absorb the impact, also helps in the climb and assists in braking.Designed and developed in the research and development center of La Sportiva, it offers real benefits during the run: the negative effect of the impact with the ground is minimized. Due to the special arrangement of the pimples, some of them come into contact with the ground beforehand, so the impact of the shoe profile is softer.
