La Sportiva Nepal Extreme notable features
Recommended for technical use on high-altitude terrain, the Nepal Extreme features the Vibram® Impact Brake System for stability and grip, the patent-pending EZ FLEX and EZ OUT for a customizable fit, and the thermal synergy lining for warmth and comfort.
It’s equipped with Primaloft insulation that is made mostly of recycled materials. The Nepal Extreme also comes with a large rand that protects the boot from abrasion while securing the stitching between the sole and the upper.

Outsole
La Sportiva has partnered with Vibram for its premium mountaineering boots. As everyone knows, Vibram soles are grippy, slip-resistant, and long-lasting. But what makes the Nepal Extreme more special is the integration of the Impact Brake System (IBS) in the outsole. This technology absorbs ground impact and increases downhill traction and grip.
The sole is also very sticky on rocks, just like climbing shoes. Lastly, it is compatible with step-in crampons.
The Nepal Extreme’s outsoles have very deep lugs, some of which are 6-7 mm deep. The heel is quite high and works well on descents and the rand keeps the lower area of the boot snow-free.
Midsole
The La Sportiva Nepal Extreme has a midsole made with 6 mm Polyurethane (PU). It’s heavier than EVA because it’s denser, which makes it more suitable for mountaineering boots where a more rigid midsole is preferred for support and stability. Moreover, PU midsoles have less bounce in the beginning but over time, the bounce lasts longer than EVA midsoles.
This midsole eliminates any problem with wear and tear in the toe box. La Sportiva has also included a removable insulating footbed for added warmth and comfort.
Upper
The Nepal Extreme boot features a durable upper made from high-quality leather from Perwanger, one of the oldest and most premium leather manufacturers in Italy. So even though it lacks a waterproof lining, this boot still has pretty strong water-repelling properties.
Meant for all high-elevation mountain terrain, this premium footwear features the innovative triple laminate lining from Primaloft. The wide toe box also plays a valuable role in the warmth of this footwear.
Completing the boot upper is a traditional lace-up closure. What makes it unique though is the patented EZ OUT pull loop that facilitates the unlocking of the lace lock. All the materials used in the upper are very durable.
