These Rieker wedge sandals are super easy to use. Just open the hook - and - loop fastener, slide your feet in, and adjust the straps for a perfect fit. For long - term use, avoid wearing them in very wet or muddy conditions as it can damage the synthetic leather. When it comes to cleaning, use a soft, damp cloth to gently wipe off any dirt. Store them in a cool, dry place, away from direct sunlight to prevent color fading.
