First hitting the ground in 1979 at the Honolulu Marathon, this landmark running shoe is back as a sneaker, and it's just as cool as it was 40+ years ago. Staying true to the original, its throwback profile sports the same streamlined construction and square-nubbed tread, with sleek nylon in the upper paired with the sole's full-length Nike Air unit that was a game-changing revolution in cushioning.
