La Sportiva Nepal Cube GTX

Colour: Black Yellow
Black Yellow
Size: EU 41

The Nepal Cube GTX is a warm and technical mountaineering boot designed to provide a lightweight yet robust boot to tackle big peaks, mixed terrain, glacier travel and vertical ice. Offering features like the carbon tech honeycomb midsole, an insulated comfort Gore-Tex® membrane and a removable and adjustable tongue, the Nepal Cubes provides a secure and precise fit to optimise your objective.

The Nepal Cube GTX shares a very similar upper to the highly successful Nepal Evo, however the Cube benefits from a state-of-the-art carbon honeycomb insole, 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 894g 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 cube

Very fast I order size to try at home and returned the one that did not fit well

Quick with the refund

Very good experience

Boots are very solid and should hold up well

Thank you

Mr.Simon L.
Fit is excellent. Easy to put on and adjust.

I tried phantom techs, trango tower extremes and cubes. Cubes are heavier but easier to put on and for me no heel lift compared to phantom techs. Trangos were probably the most comfortable but may not cope with very cold conditions. I think over time the cubes will be more rugged. But yet to use in anger. If I'd had the money I'd have kept the Trangos too for general UK cold and wet winter boots.
