The Rainier Boot’s roots can be traced back to 1975, when mountaineering legend Lou Whittaker avoided toe amputation on K2 by descending 10,000 feet in a pair of tennis shoes. His forced innovation gave him an idea for a lighter mountaineering shoe, to be worn until bulky ice boots were actually needed on the mountain. In 2016, his creation, the Rainier Boot, got a remake. The Rainier Remastered is lightweight but supportive, with a breathable full-grain leather and nylon mesh upper and a rugged Vibram sole for rocky terrain. A Gore-Tex liner has been added to keep those feet dry wherever your adventures take you. And in case you were wondering, Whittaker loves the new boots — we asked him.
