La Sportiva Olympus Mons Cube S Mountaineering Boot Yellow/Black, 45.5

The Olympus Mons Cube S is La Sportiva's warmest option for alpinists and 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.
