Olympus Mons Cube Mountaineering Boot

The La Sportiva Olympus Mons Cube Mountaineering Boot is an updated version of La Sportiva's Olympus Mons Evo. This boot still boasts the same super gaiter made of stretchy Cordura fabric, UltraSonic Welding, heat sealing, and watertight Corner Zip construction that made the original Olympus ideal for faraway mountaineering objectives, snowy base camps, and climbing peaks like Denali or even Everest. La Sportiva updated the outer boot with a dual Boa closure for a quick, simple, and secure fit. The removable inner boot now has a removable neoprene bootie for next-to-skin softness that can dry quicker than before.

La Sportiva insulated the removable inner boot with single-density foam, and the alloy-lined footbed is insulated with Primaloft's Gold Aerogel. This Carbon Tech footbed creates a stiff platform for stability on glacial traverses and support on vertical ice climbs. The Olympus Mons Cube's sole is also updated with Vibram Litebase rubber in key areas that demand durable traction, while the remaining sole features Vibram's Morflex expanded EVA rubber for a lighter weight than the original Olympus Mons Evo. The Olympus Mons Cube is now compatible with skis that have tech bindings for approaching faraway peaks, and it's still compatible with step-in crampons for the ascent.

Amazing boots, terrible liners!

I've put it through the wringer
Runs small
Size Bought
6` 2"
200 lbs

Summary - The best 8000m boot out there, but be ready to buy alternative liners. I purchased the Oly Mons Cube for Everest and tested them out this weekend in the White Mountains doing 17 miles and 9000 ft elevation gain. Comfy, warm and light boot around my feet but they ripped my shins apart. My shins were in severe pain, plus were blistered and bleeding requiring considerable time out of the boot to recover. It was the liners. I am extremely disappointed in their liners and I wouldn't survive a few days wearing these on Everest, and not what you would expect from a $1200 boot! I have a pair of Spantiks I used to climb Denali (which are comfy btw, but not suitable for Everest). I dropped in my Spantik liner, they are way comfier with the Oly Mons Cube and make a great replacement. The tongue at the front of the liner is the key (no tongue on the Oly Mons Cube liner), it stops all the chaffing. I hear from a guide friend the Baruntse liner also works well, or even better replace with an intuition liner with a tongue. I am a size 12 US, and always go up a size (bought size 47 / US 13) in all my La Sportiva boots.

Perfect for those cold days

True to size

These boots have been through the ringer!!! From climbing in Nepal and Mt. Everest to mountaineering expeditions and ice climbing trips in Alaska, these boots hold up. Super comfy after you break them in, and my feet have NEVER been cold with these guys. Super insulated. I'll be using these boots until they fall apart. (Photo: Sukakpak Visuals)
