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.

• 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.
• Active Support: These mobile wings help hold the foot in place and accompany its movement, adapting to its shape and volume.
• Chevron lugs: Lug design with deep penetration and multi-directional grip, improving traction on soft surfaces like mud or loose dirt.
• EnergyCell: A high performance EVA foam that provides shock attenuation.
• Synthetic upper material provide great durability and protection for outdoor activities.
• Water Repellent: A special treatment is applied to provide extra protection, ensuring that the fabric does not absorb water during light rain and showers.
• Mesh and textile lining: A soft, breathable lining for extreme comfort.
• Gusseted tongue: The tongue is connected to the upper on both sides, preventing debris from entering the shoe, and keeping the tongue centered.
• Lace pocket: Provides easy storage for the Quicklace™ lacing system.
• SensiFit™ cradles the foot from the midsole to the lacing system, providing a secure, snug, and virtually customized fit all around the foot.
• Welded upper: Stitch-free upper construction provides a smooth, glove-like, fit and feel.
• Protective mudguard: A wrap of leather, synthetic or rubber around the base of the foot that protects the lateral and medial sides of the foot.
• Molded OrthoLite® sockliner: Molded to match the contours of your foot, this OrthoLite® insole provides superior cushioning, as well as breathability and durability, to upgrade the comfort and performance of our footwear.
• Quicklace™: Minimalistic and strong lace for one-pull tightening. Easy-on, easy-off.
• GORE-TEX keeps your feet dry -from the outside as well as from the inside.
• PFC free: To help reduce our impact on the environment, no harmful PFC (Perfluorocarbons) are used to ensure the water repellency of our shoes. Our waterproof GORE-TEX models are free from PFCec (Perfluorocarbons of environmental concern) but may contain some PFC.
