The Air Zoom Mariah Flyknit Racer represents another stage in Nike’s long running evolution of its Racer silhouettes, the original designs debuting in the 1980s. The low-profile sneaker boasts a Flyknit upper and bootie-style construction. The woven material is supported by a Navy heel counter, while the gum outsole serves as a nod to heritage runners. The lightweight Racer is equipped with Zoom Air cushioning in the midsole.
