Using these Rieker ballerinas is a breeze. Just open the hook - and - loop fastener, slip your feet in, and adjust it for a comfortable fit. When walking, enjoy the shock - absorbing sole and the comfort of the MemoSoft cover. As for maintenance, keep them clean by gently wiping with a soft, damp cloth. Avoid using harsh chemicals as they can damage the synthetic leather. Store them in a cool, dry place when not in use to maintain their shape and quality. If you notice any loose stitching, it's best to have it repaired as soon as possible to ensure long - lasting wear.
