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.
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.
- Contagrip® MA: 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.
- ADV-C Chassis: 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.
- SensiFit™: SensiFit™ cradles the foot from the midsole to the lacing system, providing a secure, snug, and virtually customized fit all around the foot.
- Chevron lugs: Lug design with deep penetration and multi-directional grip, improving traction on soft surfaces like mud or loose dirt.
- Anti-debris Mesh: Tight mesh that prevents debris from being trapped between your foot and the footbed.
- Synthetic upper: Synthetic upper material provide great durability and protection for outdoor activities.
