To use these Romika Ibiza 99 women's sandals, simply slide your feet in and adjust the hook - and - loop strap over the instep to your desired tightness. The elastic gore details will help ensure a snug fit. When it comes to maintenance, clean the leather upper regularly with a soft, damp cloth. Avoid using harsh chemicals as they may damage the leather. If the footbed gets dirty, you can remove it and wash it gently with mild soap and water, then let it air - dry. Also, store the sandals in a cool, dry place when not in use to keep them in good condition.
