To use these sneakers, simply untie the laces, slip your feet in, and tie the laces to your desired tightness. They're perfect for everyday activities like walking around town or running errands. When it comes to cleaning, use a soft, damp cloth to wipe off any dirt or stains on the PU leather upper. For the rubber outsole, you can use a mild soap and water solution. Keep them away from extreme heat or direct sunlight to prevent the leather from drying out or cracking. And always refer to the size chart before purchasing to ensure you get the right fit.
