Mountain running shoes specially designed for ultra enthusiasts offer maximum cushioning, comfort, protection and stability during their mountain tours. They are ideal for tackling all types of trails over medium and long distances, up to 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 XFlow Endurance compound, the level of resistance and durability of the cushioning material is increased to always guarantee the same feeling of comfort from the first to the last kilometre. The sole has a large contact area and a medium rocker to increase the level of stability, while the bi-component FriXion Red sole ensures the perfect compromise between durability in the most stressed areas of the heel and maximum grip in the centre and front. The Comfort Wire upper is made of extremely soft Light TPU fabrics that are in direct contact with the foot, with externally applied TPU threads to ensure an extremely soft fit but with the right support - the perfect compromise for maximum comfort and support on the longest and most demanding outings.
