To use these Clarks Nalle Lace sneakers, simply unzip the easy - access zip, slip your feet in, and you're ready to go. They're great for everyday wear, whether you're running errands or going for a casual walk. When it comes to maintenance, use a soft, damp cloth to clean the leather uppers. Avoid using harsh chemicals as they might damage the leather. For the rubber sole, a regular wipe with a dry cloth should keep it looking good. Also, try to store them in a cool, dry place when not in use to maintain their shape and quality.
