Mountain running shoes specifically designed for ultra enthusiasts offer maximum cushioning, comfort, protection, and stability during mountain adventures. They are ideal for tackling all types of trails over medium to long distances, including some of the most iconic and toughest trail running races in the world, such as the Tor des Geants (330 km), Swiss Peak (360 km), and Tahoe 200 (320 km). Thanks to the new XFlow Endurance blend, the level of resilience and durability of the cushioning material is enhanced, ensuring the same feeling of comfort from the first to the last kilometer. The sole features a large contact area and a moderate rocker to increase stability, while the bi-component FriXion Red sole provides the perfect compromise between durability in the most stressed areas of the heel and maximum grip in the midfoot and forefoot areas. The new Comfort Wire upper is made from extremely soft Light TPU fabrics that are in direct contact with the foot, combined with externally applied TPU threads to ensure an extremely soft fit with the right support – the perfect balance for maximum comfort and hold on the longest and most challenging outings.
