IBS is a sole born from the collaboration between La Sportiva and Vibram. The sole presents a new treading system, the IBS or Impact Brake System which was designed by La Sportiva and developed by Vibram to reduce impact on hard terrain. The double-inclined “internal-external” treads align more easily to the irregularity of the terrain, for immediate and constant grip.
