These Dansko Dayna sandals are super easy to use. Just adjust the double straps using the hook - and - loop fasteners to get the perfect fit on your feet. You can wear them all day long, whether you're running errands or going out for a casual walk. For maintenance, keep them away from water as much as possible, especially since they're made of suede. If they get dirty, use a soft suede brush to gently clean them. Don't expose them to direct sunlight for long periods as it might fade the black color. Also, store them in a cool, dry place when not in use to keep them in good shape.
