To use these ARA Norderney women's sandals, simply adjust the Velcro fasteners to get a perfect fit around your feet. The sandals are suitable for various occasions, from a casual day out to a semi - formal event. As for the fit, remember they run small, so always order one size larger. When it comes to maintenance, clean the leather uppers with a soft, damp cloth. Avoid using harsh chemicals as they may damage the leather. For the textile parts, a gentle brush can be used to remove dirt. Store the sandals in a cool, dry place when not in use to keep them in good condition.
