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.
