Get ready to power through uphills and descents with this wide-fit GORE-TEX version of the updated X-ULTRA 4. It is as agile as a trail-running shoe but with all the stability, grip and waterproof protection you need to tackle technical terrain. Equipped with a new chassis, the shoe is even better at protecting sensitive articulations without compromising freedom of movement.

Trail-inspired agility
Drawing on our trail-running expertise, this shoe is lighter and more agile, so you stay nimble on uneven terrain.

Enhanced stability
The new Advanced Chassis™ targets articulations on the outer foot to optimize stability without limiting your mobility.

All-terrain grip
The All Terrain Contagrip® outsole grabs the terrain, even when it’s wet or slippery, giving you more control especially on descents.
