To use these Romika Ibiza 86 sandals, simply put your feet in and adjust the four hook-and-loop straps to your desired tightness for a perfect fit. When not in use, store them in a cool, dry place away from direct sunlight. For maintenance, wipe the leather upper with a soft, damp cloth to keep it clean. Avoid using harsh chemicals or abrasive materials. If the footbed gets dirty, you can remove it and wash it gently with mild soap and water, then let it air dry.
