To use these sneakers, just slip your feet in and fasten the Velcro 'GUESS' strap. They're great for daily wear, walking around town, or casual outings. Since they're used, expect some normal wear. When it comes to maintenance, you can use a soft brush to clean the dirt off the shoes. Avoid using harsh chemicals as the material is unknown. Store them in a dry place to prevent damage. Keep an eye on the ripped lace holders; if they get worse, you might need to repair or replace them.
