Technologies

• Impact Brake System

  This innovative system is applied to the sole so that it absorbs negative ground impact, boosts traction on ascents, and improves grip on descents. The unique positioning of the studs allows as many of them as possible to be in contact with the ground, ensuring optimal impact absorption.

• Vibram

  High-performance rubber. Vibram soles are designed based on three main principles:

  - Traction

  - Comfort

  - Protection
