La Sportiva Olympus Mons Cube S Review from Everest

This just in from our guide, Fischer Hazen, on our 2021 Mount Everest team.

I think I have found my new favorite high-altitude climbing boot. Full disclosure, I am a huge fan of La Sportiva, as their boots fit my feet well. I use them for all my shoe needs from climbing shoes to running shoes and everything in-between.

The new Olympus Mons Cube S boot takes my favorite features of two older boots and hits the sweet spot of the warmth of the old Oly Mons and the weight and climbability (pretty sure that needs to be a word) of the old G2SM. I have been using this boot guiding on Mount Everest this spring and have been really impressed. The dual BOA system is a breeze to adjust your boots without having to take big gloves or crampons off. The added neoprene sock is great as it keeps your liners mostly dry even when sweating in the boot and it seems to add some warmth as well. Overall, this boot has fully taken away the stress of keeping toes warm on a big cold mountain while also climbing like a much smaller technical boot. Awesome job La Sportiva! I would 100% recommend to friends, clients and climbing partners.
