To use these Rieker Liv R1426 sneakers, simply adjust the laces and use the zipper for easy on - off. Wear them in various weather conditions, especially when it's a bit dreary as they'll keep your feet dry. For sizing, make sure to check the measurements provided as they can vary. When it comes to maintenance, wipe the leather upper with a soft, damp cloth regularly to keep it clean. Avoid submerging the shoes in water for a long time to preserve the water - resistant properties. If the footbed gets dirty, remove it and clean it separately. Store the shoes in a cool, dry place when not in use.
