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. 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 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 balance for maximum comfort and grip on the longest and most demanding outings.
