The Nike Free Huarache Light: Retro look, barefoot feel The Nike Free Huarache Light Men's Shoe fuses legendary style with a running outsole that delivers a comfortable, barefoot feel. The shoe offers a throwback look that can be traced back to an iconic '90s college basketball squad. Benefits Mesh upper with synthetic overlays for breathability and support Phylon midsole for lightweight cushioning Outsole flex grooves for enhanced flexibility and a smooth, efficient stride Carbon rubber at high-wear areas on the outsole for durability 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.
