The Men’s Nike Zoom Fly SP running shoe is designed for maximum performance and record-breaking speed, as well as style strong enough for casual wear. The Zoom Fly SP is an upgraded edition of the standard Zoom Fly, constructed with a functional and fashionable, transparent material across the upper (replacing the original mesh construction). The Zoom Fly is designed to help you set new PRs, featuring a versatile design that’s perfect for either training or racing. The feather-light upper sits atop a thick Lunarlon foam sole that houses a full-length carbon fiber plate. This plate, which is also found in Nike’s elite-level Zoom VaporFly 4%, delivers springy energy return with every stride to propel you forward as you run. The thin yet durable transparent upper supplies an on-trend sneaker look while also being perfect for your run with its lightweight and breathable design.
