These Salomon boots are designed for moving fast in critical situations. Based on the brand's iconic XA Pro 3D trail shoe, this direct-action boot is more durable in every way to withstand the challenges of daily professional use. Every component gets reinforcement, from the stitching to the mesh to the laces to the outsole. Salomon's 3D Advanced Chassis guides the foot even on the roughest terrain and offers great protection and stability. It features a Quicklace system for easy-on, easy-off wear. The molded Ortholite sockliner is molded to match the contours of the foot, and provides cushioning, breathability and durability, to upgrade the comfort and performance. Quality full-grain nubuck leather offers longer wear and durability. The All Terrain Contagrip is built for the widest variety of surfaces. A layer of puncture-resistant material added to the outsole prevents sharp objects from penetrating the bottom of the shoe. The tongue is connected to the upper on both sides, preventing debris from entering the shoe, and keeping the tongue centered. These lace up boots have a drop value of 10 mm and a weight per unit of 490 g.
