Salomon X Ultra 4 GTX is a trekking shoe designed for daily excursions: the fastest ones. Salomon has in fact designed a shoe that is agile like a trail running shoe but stable, resistant and durable like trekking shoes. Now in its fourth edition, X Ultra 4 is equipped with the Advanced Chassis technology that protects the joints on the outside of the foot, providing even more stability without reducing freedom of movement. The All Terrain Contagrip compound offers exceptional grip on all terrains, even wet, muddy or slippery ones. And let's not forget the Gore-Tex membrane that makes the shoe completely waterproof to always keep you dry. Salomon X Ultra 4 GTX trekking shoes
