To use these shoes, simply adjust the Velcro strap to your preferred fit. Slip your feet in and enjoy the all - day comfort. When it comes to maintenance, clean the leather upper with a soft, damp cloth regularly to keep it looking great. Avoid getting the shoes overly wet as it may damage the leather. Store them in a cool, dry place when not in use. If the memory foam footbed loses its shape over time, you can replace it with a new one. Also, check the sole periodically for any signs of excessive wear and tear.
