Introducing the Nike Spark Flyknit. Utilizing a layered midsole (firm foam, plastic plate and soft foam), it reduces flection in the forefoot to help keep you energized. The visually stunning, dual-layer Flyknit upper is airy, supportive and easy to style, while the carved-away design lets you see the tech that keeps you comfortable. So if anyone dares you to keep going, lace up and accept.
