Nike Free 2.0 Preschool Kid's Shoes Size 12

The nike free run (psv) preschool girls' running shoe is made with flywire cables that wrap the foot and adapt to your stride. Deep hexagonal flex grooves in the nike free midsole provide natural flexibility with every step. 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.
