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.

Features:

• Drawing on our trail-running expertise, this shoe is lighter and more agile, so you stay nimble on uneven terrain.
• The new Advanced Chassis™ targets articulations on the outer foot to optimize stability without limiting your mobility.
• The All Terrain Contagrip® outsole grabs the terrain, even when it’s wet or slippery, giving you more control especially on descents.
• WEIGHT - 360g
