These ara ballet flats are super easy to use. Just slip them on and you're ready to go, whether it's for a day at work or an evening out. When it comes to sizing, pick your regular US size between 5 and 11.5. The medium fitting (F.5) should give you a comfortable feel. As for maintenance, keep them clean by gently wiping with a soft, damp cloth. Avoid getting them too wet, especially if it's raining heavily. Store them in a cool, dry place when you're not wearing them. This will help keep the black leather looking great and the bow in perfect shape for a long time.
