Air Zoom Spiridon Ultra 'Armory Blue'

Building upon the 1997 shoe that pioneered Nike Zoom technology, the Air Zoom Spiridon Ultra brings Hyperfuse construction to a retro runner in eye-catching teal. Named after the first Olympic Marathon champion—Greek national hero Spiridon Lewis—the shoe is designed to encourage the simple joy of running in a breathable, low-profile package. To accomplish this, a one-piece mesh upper covers a stretchy neoprene sockliner while Zoom Air cushioning creates a smooth, responsive ride.
