To determine the right size, measure the child's foot from heel to toe using a tape measure. Add 1 additional centimetre and find the closest matching number in the chart (rounded up) — that’s the correct size.
If you are unable to measure the child's foot, please check the Approximate Age category. Bear in mind that this is a rough estimate and that every child is different.
