Children have different head circumferences - choose one size up if your child has a slightly larger head than their peers.
Example: If the foot measures 15.0 cm, choose a shoe with an inner length of approx. 16.5 cm.
Socks and tights may shrink slightly in the wash - choose one size up if in doubt.
If you are unsure about the size or fit, you are always welcome to contact our customer service - we are happy to help you find the right size.
