The X Ultra 4 is a hybrid hiking shoe that borrows from trail running technologies, this shoe is the result of in-depth biomechanical studies aimed at delivering better stability to prevent ankle injuries.
As lightweight and agile as a trail-running shoe but with all the stability, grip and waterproof protection you need to be nimble on technical, uneven terrain. The X Ultra 4 GTX® is equipped with a new ADV-C Chassis that targets articulations on the outer foot to optimize stability without limiting your mobility. The result is a shoe with more protection without compromising freedom of movement.
