The Nike Air Zoom Maxfly spikes are designed for use on standard synthetic track surfaces. Before your first use, ensure the spikes are securely tightened. Spike lengths may vary, so confirm they meet competition regulations for your specific event. To maintain your Maxflys, clean them after each use by gently brushing off dirt and mud from the sole and upper. For deeper cleaning, use a mild soap solution with a damp cloth on the upper, then air dry them away from direct heat or sunlight. Always store them in a cool, dry place, preferably in a shoe bag, to protect the spikes and upper material. Avoid machine washing or drying, as this can damage the specialized components.
