Using these Pikolinos Palma sandals is a breeze. Just open the hook and slip your feet in. You can wear them for a day out shopping, a casual lunch with friends, or even a semi - formal event. When it comes to maintenance, keep them away from direct sunlight for long periods as it may fade the black color. Clean them regularly with a soft, damp cloth to remove dirt and dust. For tough stains, use a mild leather cleaner. Store them in a cool, dry place when not in use, preferably in a shoe box or a dust bag to protect them from scratches and damage.
