Using these shoes is super easy. Just slip them on and you're ready to go! They're great for casual outings, work, or any event where you want to look stylish and feel comfortable. When it comes to sizing, take your time to measure your feet as described in the size chart to get the perfect fit. For maintenance, keep them away from sharp objects to avoid scratching the PU upper. You can clean them with a soft, damp cloth. If they get wet, let them dry naturally at room temperature. With proper care, these shoes will serve you well for a long time.
