The program is driven by Native American wisdom of the Seven Generations: In every deliberation, we must consider the impact of our decisions on the seventh generation. The ultimate goal of Nike N7 is to consider this impact and to help Native American and Aboriginal youth recognize their proud history and build on it for a triumphant future. Nike Free Origins After learning that Stanford athletes had been training barefoot on the university's golf course, three of Nike's most innovative and creative employees set out to develop a shoe that felt natural and weightless, similar to bare feet. In 2002, they examined a group of men and women with pressure-measuring insoles taped to their feet, using high-speed cameras to capture images of each foot in motion. The team spent eight years studying the biomechanics of shoeless running. The results yielded a profound understanding of the foot's natural landing angle, pressure and toe position, allowing Nike designers to build an unconventional and flexible running shoe from the inside out.
