To use these Rieker ballerinas, simply open the hook-and-loop fastener, slip your foot in, and adjust it for a snug fit. When wearing them, you'll notice how comfortable they are right away. As for care, avoid getting them extremely dirty by not wearing them in very muddy or wet areas. If they get dirty, use a soft, damp cloth to gently wipe them clean. Don't use harsh chemicals or abrasives as they could damage the synthetic leather. Store them in a cool, dry place when you're not using them to keep their shape and quality.
