Size: 12.5cm Color: Black I am listing this item because the size didn't fit after trying it on upon arrival. The product size is listed as 12.5cm, but it was a little too small and didn't fit my daughter's feet, who usually wears 12.5cm shoes. It may depend on the shape of your child's feet, but I think it would fit children with feet between 11.5cm and 12.0cm.
