The Nike Flyknit Racer sneaker is designed with the needs of runners in mind. The result is a lightweight sneaker with the snug fit of a sock, made with a breathable Flyknit bootie construction knit from black and white threads for a high-graphic look. The sneaker incorporates an easy slip-on design, responsive Nike Zoom Air cushioning, and an eco-friendly mindset: each pair of Flyknit sneakers contains the equivalent of six recycled plastic bottles.
