>The Olympus Mons Cube S is La Sportiva’s warmest option for mountaineers ascending the coldest, most extreme mountains on the planet. We certainly appreciate the reliable protection and technical prowess in arctic climates, but we’d be amiss to not mention its ease-of-use, quick-and-easy Boa dials, and removable thermal booties for base camp.
• Maximum thermal insulation with space-age technology
• Skitrab Tech inserts making the boot ideal for arctic crossings with skis & skins (no rear attachment, not intended for downhill)
• Vibram® Litebase and Vibram® MorFlex® expanded EVA provide a lightweight, abrasion resistant and thermally insulated outsole
• Click here for important heat moldable liner instructions
• Corner Zip™ zipper allows full opening and direct access to the Dual BOA® closure system
• Double removable thermal booties
• Dual BOA® system differentiates the lacing between the upper and lower portions of the internal boot, designed to be used with gloves
• Compatible with various non-automatic, semi-automatic, and automatic crampons. Crampon compatibility is NOT ensured, and boot-crampon compatibility needs to be inspected
