Overview
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.
