To use these shoes, simply lace them up tightly enough for a secure fit but not too tight to restrict blood flow. You can wear them for various training activities like running, jogging, or gym workouts. When it comes to maintenance, clean the shoes regularly with a soft brush and mild soap. Avoid using harsh chemicals as they may damage the materials. Let the shoes air - dry naturally and keep them in a cool, dry place. If you notice any signs of wear and tear, especially on the sole, it might be time to consider getting a new pair to ensure your safety and comfort during training.
