La SportivaOlympus Mons Cube - Mountaineering boots

For adventurers ready to tackle the Himalayan peaks, Arctic crossings, and the most extreme environments, the Olympus Mons Cube mountaineering boot by La Sportiva is the ultimate solution. Designed for the most rigorous conditions, it incorporates cutting-edge technologies to offer thermal resistance, lightness, safety, and waterproofing.

With its reduced external volumes and lightened weight, this double thermal boot for high mountains stands out for its ultra-clean and homogeneous design, achieved through UltraSound Welded technology that assembles materials without seams. The Corner Zip™ closure extends longitudinally along the gusset, allowing for a full opening for easy access to the inner shell. Equipped with the double BOA® Fit quick closure system, it guarantees a precise and differentiated fit between the upper and lower parts, even with gloves.

The removable inner boot, equipped with an additional insulating layer, facilitates drying operations at the base camp, while the Vibram® Litebase + Vibram® Morflex sole ensures unmatched insulation and lightness thanks to the use of reduced rubber combined with an abrasion-resistant expanded material. Compatible with mountaineering ski bindings, the Olympus Mons Cube is an exceptional choice for the most demanding expeditions.
