Setup: 1. Lacing: Loosen the laces and slide your foot into the shoe. 2. Secure Fit: Tighten the laces evenly from the toes to the ankle, ensuring a snug but comfortable fit. 3. X-Cross Strap: Fasten the X-cross strap over the midfoot. Adjust its tension to firmly lock your foot in place without restricting circulation. This strap is crucial for energy transfer. Compatibility: These spikes are specifically designed for long jump events on synthetic track surfaces. While they offer multi-surface traction, their specialized design makes them less suitable for other track and field events (e.g., sprints, middle-distance running) or general training. Care: 1. Cleaning: After use, remove any dirt or debris from the spikes and outsole using a soft brush. Wipe the upper with a damp cloth and mild soap if necessary. Air dry completely away from direct heat. 2. Spike Maintenance: Regularly inspect the spikes for wear. Worn or damaged spikes can be replaced. Ensure all spikes are securely tightened before each use. 3. Storage: Store in a cool, dry place. Avoid leaving them in direct sunlight or extreme temperatures.
