Mountain running shoes specifically designed for ultra enthusiasts offer maximum cushioning, comfort, protection, and stability during their mountain adventures. They are ideal for tackling all types of trails over medium to long distances, including some of the most iconic and challenging 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, we have increased the resilience and durability of the cushioning material to ensure a consistent feeling of comfort from the first to the last kilometer. The sole features a large contact area and a moderate rocker to enhance stability, while the bi-component FriXion Red sole provides the perfect balance between durability in the heavily used heel area and maximum grip in the midfoot and forefoot regions. The new Comfort Wire upper is made from extremely soft Light TPU fabrics that come into direct contact with the foot, with externally applied TPU threads to ensure an extremely soft fit while providing the right support. This is the perfect compromise for maximum comfort and grip on the longest and most demanding outings.
