  • Salomon designers, in collaboration with athletes, updated the S/Lab X Alp Carbon 2 GTX. The current version now features an asymmetrical zip-up closure for a more efficient movement. The brand still equipped it with their protective and cozy features—rubber rand, mudguard, inner linings (Gore-Tex and Anti-Debris Mesh) and Sensifit.
  • Various EVA densities are used in the midsole, topped with an Ortholite footbed. The Carbon Edging Chassis yields a flexible yet stable stride.
  • Still enabling users to go fast and light is the Contagrip outsole. Its tread profile can tackle a variety of trails.

This unisex low-cut mountaineering shoe is available in a range of sizes. It is offered in standard width and relatively runs true to size. Based on Salomon's sizing guide, women are advised to go one size down to get the correct fit. Its Quicklace system helps secure a snug fit.

The S/Lab X Alp Carbon 2 GTX has the Non Marking Mountaineering Contagrip outsole. It features large, multi-directional grooves that prevent muck build-up and enables the outsole to self-clean. Likewise, it grips on most types of terrain and is compatible with crampons.

A dual-density EVA midsole coupled with compressed EVA cradles the foot for a cushy and comfy ride. It also helps absorb shock from impacts. A molded Ortholite sockliner conforms to the shape of the foot, promotes breathability and facilitates moisture management. The Carbon Edging Chassis from Salomon enables the foot to flex while providing lateral edging and stability comfortably.

This mountaineering shoe has an asymmetrical zippered gaiter with a snap button. For an easier closure, this is backed up the brand’s Quicklace system which uses a one-pull Kevlar string.

The upper is made from a combination of water-resistant textile and synthetic. Inside is a low-cut shoe which features the Gore-Tex Performance Comfort and Anti-Debris Mesh linings. The former brings weatherproofing while the latter helps keep trail debris off the foot. Plush comfort is given by a heel foam.

With the Sensifit technology (a feature that maintains the shoe’s structure and delivers a precise fit) and a seamless construction, hot spots are prevented. A high-cut tongue is also added to shield the foot from crampon straps.

A TPU mudguard which sheds off mud surrounds the base of this shoe, granting a clean facade. Its EVA protected forefoot, heel cap and ankle pad render protection on rocky trails. Also, a heel strap is added for easy donning and doffing.

  • This mountaineering shoe is compatible with flexible strap crampons.
