To use these Rieker slippers, just slide your feet in as they don't have a fastener. You can wear them around the house or for short outdoor trips. For maintenance, clean the synthetic leather upper with a soft, damp cloth. Avoid using harsh chemicals as they may damage the material. When not in use, store them in a cool, dry place. Remember to take out the removable insole regularly to air it out for better freshness. These slippers are water - resistant, but don't soak them in water for a long time to keep their quality intact.
