Using these Pikolinos sandals is a breeze. Just slip your feet in and adjust the hook - and - loop strap on the instep to get a snug fit. They're great for casual outings or a day at work. When it comes to maintenance, use a soft, dry cloth to wipe off any dirt or dust regularly. For deeper cleaning, you can use a mild leather cleaner on the calfskin upper and pigskin lining. Avoid getting the synthetic sole wet for long periods as it may affect its quality. Also, store them in a cool, dry place when not in use to keep them in good condition.
