NIKE FREE SOURCES
After discovering that Stanford athletes trained barefoot, three of Nike's most innovative and creative employees started to develop a shoe that felt almost the same light and natural sensation of barefoot running. The team spent four years studying the Biomechanics of movement of the feet of the runner. The results yielded a deep understanding of the foot's natural landing angle, pressure and position of the fingers, allowing Nike designers to build an unconventional and flexible shoe both inside and out.
