A burly, warm, technical, insulated leather mountaineering boot with state-of-the-art technology for rugged mountaineering, glacier travel, ice climbing, and mixed conditions and terrain.  A Gore-tex® Insulated Comfort Membrane provides waterproof/breathable insulation.  Additional warmth is provided by an insulated insole.  A shock-absorbing midsole provides extra cushion for long approaches.  The unique two-part removable and adjustable variable-fit tongue micro-adjusts the fit and volume of the boot to accommodate a large variety of foot shapes and sock needs. Ideal for Cascade winter mountaineering and steeper north side spring/summer routes, moderate temperature ice climbing, mixed climbing, and summer climbs of peaks like Mt Rainier. We find these "Nepal Evo" boots to be more comfortable than the nearly identical "Nepal Cube" version for long approaches, and also more versatile and well-balanced for most climbers.  These also have great ankle support and are excellent when kicking steps in the snow for thousands of feet is required on the way up and endless plunge stepping in softer snow is encountered on the descent.  Compatible with many different styles of crampons, including general purpose mountaineering, technical ice climbing, and lightweight aluminum models.  This award winning and best selling Nepal Evo Gtx is an industry standard, and a premier benchmark in the mountaineering boot category to which many other boots are compared.
