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. * Improved stability - The new ADV-C Chassis targets articulations on the outer foot to optimize stability without limiting your mobility, while the higher cut provides extra ankle support. * 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 - Protecting ankle articulations on the outer foot, this chassis provides extra stability while also keeping the front of the shoe flexible for a more fluid ride. * SensiFit™ - SensiFit™ cradles the foot from the midsole to the lacing system, providing a secure, snug, and virtually customized fit all around 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. * 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. * Water Repellent - A special treatment is applied to provide extra protection, ensuring that the fabric does not absorb water during light rain and showers. * 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. * GORE-TEX - GORE-TEX keeps your feet dry -from the outside as well as from the inside.
