The Barefoot Impi is a group of adventure activists who make their impact on the world not by holding signs, preaching, or organizing mass protests, rather by being barefoot. They claim their inspiration comes from "the sixties, the counterculture of the hippies leveraged bare feet as a sign of rebellion and probably to induce a return to an age of innocence, peace, and Mother Nature. But then later, athletes Zola Budd of South Africa and Abebe Bikila of Ethiopia drew the world's attention to the spectacle of barefoot sport. Today we have the likes of North Pole swimmer Lewis Pugh, and barefoot polar circle half-marathon runner Wim Hof, exposing their feet and bodies to the most incredible temperatures - and living to tell the tale. The time of barefoot endurance, it seems, has arrived. Or are we simply going full circle and once again returning to our natural state?"

Through a variety of difficult specially designed challenges the Barefoot Impi sets out to raise awareness and funds in support of the Red Cross War Memorial Children's Hospital.

The team has endured months of preparation involving barefoot hiking, running and virtually living without shoes in order to give the climber's feet the best possible chance against the elements on the mountain.
