La Sportiva Nepal Cube GTX
Our Take
This boot is the Guide Pick™ for mid-season Rainier climbs, or anywhere a single, leather boot is required! 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 insole, an insulated comfort Gore-Tex® membrane and a removable and adjustable tongue, the Nepal Cubes provides a secure and precise fit to optimize your objective.
We recommend ordering this boot 1/2 size larger than your typical US size. See drop down selection for European/US size equivalents. Note that a "plus" size is slightly larger than a US half size but smaller than the next whole size.

Nepal Cube GTX
I've got a bit of a low volume foot, but these crank down just right; 2 Rainer summits, Olympus, Sahale, St Helens (!), Shuksan and Baker.... Comfy!
I have ice climbed in Ouray for two seasons with these boots and I just love them. If you have ever ice climbed, you know how much time is spent just standing while belaying your climbing partner. My feet never got a bit cold.
