To use these shoes, simply put them on like you would with any other pair of running shoes. Tie the laces tightly for a secure fit. When running, these shoes are suitable for various terrains, so feel free to explore different paths. As for maintenance, clean the shoes regularly with a soft brush and mild soap. Avoid using harsh chemicals as they may damage the Matryx upper. Let them air dry naturally. Store the shoes in a cool, dry place when not in use. Also, check the outsole periodically for excessive wear and replace the shoes when needed to ensure optimal performance and safety.
