Push the boundaries of off-trail running to a new altitude with the S-Lab Xa Alphine trail shoes designed to conquer adventures above tree line. They run fast and light, but fly over rugged terrain without regard for mud, snow, or debris. They use a unique, patented Edging Chassis to enable forefoot flexibility without sacrificing lateral stability, and at an incredibly low weight, to make ascents easier and faster. Run with the lightweight comfort and precision of Salomon's S-Lab Sense platform. They also feature water resistant textile, protective toe cap, protective ankle pad, Sensifit quicklace lycra collar, lace pocket, lateral zip gaiter, endofit climbing zone, and dual density compressed EVA midsole.
