Setup: Upon receiving your Nike Air Zoom Victory 2 spikes, ensure that all removable spikes are securely fastened into the spike plate. A spike wrench (often included with new spikes) should be used to tighten them. Check spike tightness before each use. Compatibility: These spikes are specifically designed for track surfaces, including synthetic tracks (e.g., mondo, tartan) and cinder tracks. They are not recommended for use on roads, trails, grass, or any other non-track surface, as this can damage the spike plate and compromise performance. Care: After each use, gently brush or wipe any dirt or debris from the upper and spike plate. If mud accumulates, use a damp cloth to clean it off. Allow the shoes to air dry completely at room temperature; do not expose them to direct heat sources like radiators or sunlight, and avoid machine washing or drying, as this can damage the materials. Store your spikes in a breathable bag or in a cool, dry place to prevent mildew and maintain their integrity. Periodically inspect the condition of your spikes and replace any that are worn down or bent to maintain optimal traction.
