ZARA KIDS ballet flats. Size is 33, which is 21cm. Only tried on once in the entryway, so they are almost new. The inside of the right shoe was frayed from the time of purchase. I don't think it will be noticeable when worn. I'm selling them because my child outgrew them while they were in storage, so they are almost new. These are not shoes for ballet dancing. There may be oversights. I look forward to your purchase if you understand. ZARA Zara ZARAKIDS Zara Kids
