Using high-strength fibers to create a lightweight upper with targeted areas of support, stretch and breathability, Nike Flyknit footwear is designed for performance. Getting the shoes dirty comes with the territory.

Whether you put on Nike Flyknit sneakers for running, soccer, basketball or everyday wear, they’re bound to encounter scuffs. Regularly cleaning your knit or mesh shoes can help keep them in shape — and looking fresh.
