To use these Rieker sandals, simply slip your feet through the elastic band. They're great for casual outings or a day at the beach. When it comes to maintenance, use a soft cloth to wipe off dirt and stains. Avoid exposing them to extreme heat or direct sunlight for long periods, as this can damage the synthetic leather. If they get wet, let them air - dry naturally. These sandals are built to last, but gentle care will keep them looking and feeling their best.
