Using these sandals is a breeze. Just adjust the hook and loop closure to get your perfect fit. You can wear them with the backstrap on for more support or take it off when you want a more relaxed feel. When it comes to maintenance, after getting them wet, let them dry naturally in a well - ventilated area. Avoid direct sunlight as it may damage the leather. Regularly wipe the leather upper with a soft, dry cloth to keep it looking good. Remember, these sandals are only available in whole sizes, so choose the one that suits you best.
