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.
-
EVA moulée
Ensures very good cushioning and aids during the propulsion phase. It is more responsive on soft ground where shock absorption may be reduced.
-
Infinitoo
Polyurethane sole with high cushioning that provides excellent energy return.
-
Ortholite MR E
Ortholite Mountain Running Ergonomic insole offers several advantages:
Major breathability for enhanced comfort thanks to plantar aeration, promoting sweat evaporation while keeping the foot dry, prolonged durability over time thanks to a technology that prevents excessive wear, antibacterial treatment and washable products for better overall foot hygiene.
