The La Sportiva Nepal Cube is an incredible technical mountaineering boot which looks to have raised the bar in terms of weight and warmth in a single leather boot. The Nepal Cube shares a very similar upper to the highly successful Nepal Evo, however the Cube benefits from a state-of-the-art carbon honeycomb midsole, which is warmer, lower profile, and lighter (by about 200g per pair), than the Evo.

La Sportiva say:

"Nepal Cube, as the name suggests, is a new starting point for defining technical mountaineering boots thanks to the exceptional lightweight and thermal properties (a mere 825g per half pair).

These features are achieved from the reduced weight of the sole/midsole using a Carbon Tech honeycomb, a thermal footbed and lightweight mini steel parts. The Gore-Tex Insulated Comfort lining contributes to the overall comfort of the boot, guaranteeing breathability and water resistance. EZ OUT technology for the tongue allows more precise regulation of the fit and encourages the elimination of sweat via a mesh fabric which draws humidity to the surface. The 3D Flex System provides comfort during walking and support for the ankle on steep terrain. The Vibram sole with Impact Brake System absorbs negative ground impact, while the graded lugs promote traction and keep feet in check on downhill terrain. Nepal Cube: the origin of a new species."

Please note the Nepal Cube has a lower volume fit compared to the Nepal Evo.

La sportiva Nepal cube gtx.

I think these are the best boot I have ever owned. I bought these for winter mountaineering and summer Alpine but have ended up wearing them for everything. So comfortable I never won't to take them off. Great service from Rock and run.


Great overall boot

Initially purchased the classic Evo and did a winter season in Scotland with them. Were a bit to snug so I wanted to go for a size up. When I got to the store the Cube's got my attention. Tried them and intermediately went for it. Used them dozen of times last summer in the Mont Blanc massif and Gran Paradiso. Ice climbing and mixed climb. Kept me dry and warm. The Evo's are a true classic but these are better. Lighter and better weather resistant. Better ankle support. Have been used with Grivel G12 and G20 and also Petzl Dart. The only inconvenient is the stock laces that sometimes come undone. Overall happy with the purchase.

The pictures of the cubes

The pictures of the cubes do not do them justice, they are not as "clowny" as they look and the logo is very tasteful.Exact same features of the evos only lighter. Additional tongue is useful if you have narrow feet but I found them quite snug, do allow for socks. Haven't used them yet but have done a lot of admiring! Rock n run got them out to me quick time and at a good price.

Bravo, La Sportiva

These are the one's I've been waiting for. I have been using the Evos for the last few years which are great boots themselves. The Cube are noticeably lighter, still feel very solid rock hard rand, same grippy and tough soles, leather feels the same, over
