DetailsThe alpine is calling.The La Sportiva Women's Nepal Cube GTX Mountaineering Boot was designed and built for long days spent on the glacier and early mornings climbing a combination of vertical ice and rock. This lightweight single boot is ideal for all but the world's highest peaks, and features a Gore-Tex Insulated Comfort insert for waterproof and breathable performance and cozy comfort in cold alpine climates. The tough upper is composed of Sportiva's Idro-Perwanger leather upper, which is silicone-impregnated for added protection from moisture, and it's reinforced with a full-wrap rubber rand to protect the boot from front point shrapnel. Underfoot, the Nepal Cube is fitted with a low-profile Carbon Tech honeycomb insulated footbed to add warmth while still maintaining a stiff feel for secure climbing. The PU midsole with toe and heel welts accommodate step-in crampons, while the aggressive Vibram sole offers rock-solid traction during the approach to the glaciated flanks of your objective.Gore-Tex waterproof and breathable membraneIdro-Perwanger Roughout leather upperAir-injected rubber randLace closureGore-Tex Insulated Comfort liningCarbon Tech honeycomb insulated footbed4mm EVA insolePolyurethane midsoleRe-soleable Vibram sole with Impact Brake SystemStep-in crampon compatibleItem #LSP00A9Tech SpecsUpper MaterialIdro-Perwanger (silicon-impregnated leather), [rand] air-injected rubberWaterproofingGore-Tex membraneInsulationGore-Tex Insulated ComfortRemovable LinernoClosurelaceLastWomen's NepalFootbedCarbon Tech honeycomb, EVA (4mm)MidsolepolyurethaneSoleVibram, Impact brake systemStylesingle bootCrampon Compatibilitystep-inClaimed Weight1 lb 8 ozRecommended Usealpine & expeditionManufacturer Warranty1 year
