The Air Huarache Run, a modified version of the original 1991 release, has been specifically designed for long-distance purposes. This upgraded model showcases a lightweight and perforated ankle design, coupled with Air-Sole units that enhance its responsiveness. In 2016, the design was revamped to exude a sleek and understated appearance, where every aspect of the shoe, including the distinctive strap system and neoprene bootie, has been clad in black. This monochromatic aesthetic extends to the contoured Phylon midsole and rubber outsole, which boasts V-flex grooves to facilitate natural flexibility during movement.
