FOOT SHAPED TOE BOX: Allows your toes to spread out comfortably and naturally and for the big toe to reduce pronation. The result is improved stability and increased propulsion for optimal running performance.


GaiterTrap®: Innovative velcro tab allows easy attachment of gaiters without having to fix them under the sole. Prevents debris from building up in and beneath the shoe.


InnerFlex™: Internal grooves in the midsole. By increasing multi-dimensional flexibility they allow the feet to be more responsive and improve speed and performance. This technology also reduces the weight of the shoe for a better running experience.


Balanced Cushioning™ Platform: System that places the heel and forefoot at the same distance from the ground to stimulate low impact when running.


Vibram®: The benchmark for abrasion-resistant rubber soles. Exclusive compositions are created according to the specific requirements of each activity. For hiking and trekking, shoes with Vibram technology have a sole that ensures optimal traction, support and cushioning, even on uneven terrain.

MEGAGRIP: Technique developed by Vibram® for slippery surfaces. MegaGrip provides excellent grip for wet and dry ground, while maintaining a high level of durability. It provides an unbeatable combination of traction and durability.




EVA: The moulded EVA foam insert is particularly flexible. It helps improve shock absorption and lightness.
