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

Benefits
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 ADV-C Chassis targets articulations on the outer foot to optimize stability without limiting your mobility.

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

Features
-Contagrip® MA is built for the widest variety of surfaces. It balances both the geometry and the rubber compound to deliver confidence on wet, dry, hard or loose surfaces, and offer long-term durability.

-Keeping outer ankle articulations safe and protected, this chassis brings extra stability while leaving the front of the shoe soft and flexible to move freely with a fluid stride.

-Stitch-free upper construction provides a smooth, glove-like, fit and feel.

-A wrap of leather, synthetic or rubber around the base of the foot that protects the lateral and medial sides of the foot.
