Get ready to power through uphills and descents with the updated X ULTRA 4. It is as agile as a trail-running shoe but with all the stability and grip 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.

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

The new ADV-C Chassis targets articulations on the outer foot to optimise stability without limiting your mobility.

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