To use these sneakers, simply lace them up to your desired tightness. Make sure to measure your feet accurately before choosing a size to avoid discomfort. When it comes to maintenance, use a soft cloth to wipe off dirt on the patent leather upper. Keep them away from sharp objects to prevent scratches. For the rubber outsole, a gentle wash with mild soap and water can help maintain its grip. Store them in a cool, dry place when not in use.
