Mountain Running shoe specifically designed for “Ultra” enthusiasts who seek maximum cushioning, comfort, protection, and stability during their mountain adventures. Ideal for tackling any type of trail over medium and long distances, including the world’s most iconic and toughest trail races such as Tor des Géants (330 km), Swiss Peak (360 km), Tahoe 200 (320 km), and more! Thanks to the new XFlow Endurance compound, we’ve increased the resistance and durability of the cushioning material to ensure the same comfort from the first to the last kilometer! The sole unit features a large contact surface and a medium rocker to enhance stability, while the dual-compound FriXion® Red outsole offers the perfect balance between durability in high-wear heel areas and maximum grip in the midfoot/forefoot zones. The new Comfort Wire upper is made of extremely soft Light TPU fabrics in direct contact with the foot, combined with external TPU threads to provide a plush fit with the right level of support, the perfect compromise for ultimate comfort and stability on the longest and most demanding outings!
