To use these Rieker slippers, simply slip your feet in through the elastic opening. They're easy to put on and take off, so you can quickly get on with your day. When wearing them, you'll enjoy great comfort due to the shock - absorbing sole and soft cover sole. As for maintenance, you can use a soft cloth to wipe off any dirt on the synthetic leather. Avoid exposing them to excessive moisture or heat, as this could damage the material. Also, try to keep them in a cool, dry place when not in use. Don't worry about the sole wearing out quickly, as the RIRICON sole is quite durable, but if you notice any significant wear, it might be time to replace the slippers.
