The Nike Huarache Run Now GS 'Green Grape' was released for grade school kids in April 2019 featuring a multi-color build and the distinctive containment system of the adult version. Synthetic leather layers support the flexible neoprene bootie underneath, while the crisscrossing back strap stabilizes the heel. The adult original was designed by Tinker Hatfield in 1991, mimicking the stretchy, contoured fit of a water-skiing boot.
