Using these shoes is super easy. Just slip them on and you're ready to go. When it comes to sizing, since they fit true to size, you can simply order your regular size. For maintenance, it's a good idea to clean the suede part gently with a suede brush to keep it looking nice. Avoid getting the shoes too wet, especially the suede. If the rubber sole gets dirty, you can use a damp cloth to wipe it clean. Store the shoes in a cool, dry place when not in use. And remember, the box isn't included, so you'll need to find your own way to keep them safe when storing or traveling.
