The Nike Free Run 3.0 Shoe: Comfortable and lightweight
View Larger Fullscreen
With deep flex grooves and a glove-like fit, the Nike Free Run 3.0 (3.5y-7y) Boys' Running Shoe delivers outstanding support while allowing the foot to move naturally, which helps build strength with every step. 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, just like 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.
