A high-tech double boot for high altitude mountaineering

The Nuptse provides excellent warmth for 6-7000 meter peaks and alpine climbs in cold environments. The upper is a bit stiffer than the Spantik but it shares the same Benecke CeraCom PUR leatherette waterproof reinforcement. The removable inner boot is lasted on European half sizes as well as the outer boot that provides the perfect fit in a warm durable double boot. The Nuptse also works great with split-boards!
