These lace - up platform sneakers are super easy to use. Just lace them up and you're ready to go. They're perfect for daily wear, whether you're running errands or going out with friends. When it comes to sizing, remember to order your usual size as they fit true to size. As for maintenance, use a soft cloth to wipe them clean. Avoid exposing them to extreme heat or cold as it may damage the rubber and PU leather material. If they get wet, let them dry naturally. And since they don't come with a box, find a nice place to store them when you're not wearing them.
