To use these Nunn Bush men's slip-on shoes, simply slide your feet in and go. They're great for daily wear, whether you're running errands or just hanging out. When it comes to maintenance, use a soft brush to remove dirt regularly. For stains on the leather upper, you can use a mild leather cleaner. Avoid exposing the shoes to extreme heat or moisture for long periods. Also, don't machine wash them as it might damage the materials. If the insoles get smelly, take them out and air them. This will keep your shoes in good shape and looking great for a long time.
