The Salomon X Ultra 4 Mid GTX Hiking Boots are agile on the way up, stable, and grippy on the way down. Get ready to power through uphills and descents with this mid-cut GORE-TEX version of the updated X-ULTRA 3. 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 boot is even better at protecting sensitive articulations without compromising freedom of movement. The Contagrip MA outsole grabs the terrain, even when it’s wet or slippery, giving you more control especially on descents. 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. 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.
