La Sportiva Olympus Mons Cube U 13

The best 8000m boots you can buy, and the newest updated mons cube version. Super warm and comfortable. Bought and worn for the 2022 Everest expedition. Fully functioning and In excellent condition, check pictures for any signs of slight wear on the sole from the initial entry into the icefall. Even better, the Inner boots are brand new (have never been worn) as I used my intuition liners. 46% off the original purchase price. Rule of thumb, go up one full US size. I am a size 12 US, hence fit perfectly in the 13 US mons cube with mountaineering socks.

The Olympus Mons Cube offers maximum warmth and minimal weight for alpinists crossing the coldest, most barren expanses and the highest most extreme mountains on earth. Dual BOA® closure system allows you to fine tune the fit. Double removable PE and EVA thermal booties together with the Vibram®, LITEBASE and MOREFLEX expanded EVA outsoles insulate and provide comfort and customization. SkiTrab tech inserts make the boot ideal for arctic crossing with skis and skins.
