I purchased these at Aeon. They are listed as 9-15cm, but they were too small for my child who wears 13cm shoes, so they have only been worn 2 or 3 times each. Therefore, I am listing the size as 12cm. There is some pilling from washing, but they are still in good condition. The white sock on the far right has my child's name written on the inside ankle area, so I will erase it with a marker.
