Setup, Compatibility & Care
To ensure the longest lifespan for the Nike Flex Runner 4, keep these care tips in mind. The trainers are designed for immediate wear right out of the box; no break-in period is typically required. When cleaning, avoid submerging them in a washing machine, as this can degrade the specialized adhesives and materials. Instead, wipe away surface dirt with a damp cloth and mild soap. Air dry the shoes away from direct heat sources, like radiators, to prevent material warping. Always check the sizing periodically, as active children's feet grow quickly, and a properly fitted shoe is vital to reap the full performance benefits of the flexible sole.
