Per Nike: A pioneer in lace-free support, the Air Trainer Huarache has evolved from a cross-training staple into a street-certified classic. Originally designed by Tinker Hatfield, the new interpretation combines a distinctive cross-training feel with a bold new look. The latest Air Trainer Huarache draws upon New York City for inspiration. A cement speckled wolf grey upper reflects NYC’s “Concrete Jungle” nickname. The volt glow-in-the-dark outsole reminds you that some cities never sleep. Finished off with a stitched Nike NYC heel logo its only fitting to call these “Cement City”.
