Plenty of backpackers and mountaineers have insulated tent shoes and booties for doing chores indoors but The North Face Nuptse Bootie has a cushioned EVA outsole and high traction tread that makes it easy to transition between the team dome tent and the alpine environs beyond the fly. The water resistant nylon fabric is breathable and comfortably protects your feet from light rain and moderate sticky snow. The Nuptse is durable enough to wear throughout your base camp stay--especially when you're waiting for your backpacking and mountaineering boots to dry out in the rarified air.
