The X Ultra was developed from Salomon’s hugely successful XA range of trail running footwear. It features the same Advanced Chassis for superb support & control with a deeply lugged Contagrip sole unit for superior grip on loose or muddy ground. The upper is made from a lightweight breathable mesh, a protective rubber toe cap & Mud guard. The unique Sensifit fit system provides the secure foot hugging fit; this consists of the zig-zag lacing anchor, the asymmetrical placement of the lace loops & the Quicklace lacing system. All of this really holds your foot securely by evenly tensioning from the sides to the top of the shoe.
