Why We Like The G5 Mountaineering Boot

We rely on the La Sportiva G5 Mountaineering Boot when we have our sights set on unknown terrain and epic first ascents. This highly technical big mountain boot boasts a stretchy Cordura gaiter equipped with a waterproof membrane and a heat-sealed zipper to keep wetness at bay. The durable upper features flex zones to keep you trekking and climbing anatomically, while the insulated felt works with the insulated footbed to maintain warmth. Vibram's Matterhorn rubber sole includes large lugs and step-in crampon compatibility.
