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.
