La SportivaOlympus Mons Cube S - Mountaineering boots

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

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

The removable inner liner, with an additional insulating layer, facilitates drying operations at the base camp, while the Vibram® Litebase + Vibram® Morflex sole provides 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 S is an exceptional choice for the most demanding expeditions.
