Initially released in 1977, the Nike Waffle Racer was seen as one of Nike's first breakthrough innovations due to its rubber outsole, which gave runners unparalleled traction on a track. In honor of its 40th anniversary, the Waffle Racer is back in a fluorescent green colorway featuring a black nylon and suede upper as well as rainbow-hues on its tongue and outsole designs. Released as part of Nike's Rainbow Pack, the Waffle Racer is available now priced at $100 for lovers of vintage Nikes and bright-colored shoes.
