Shoe size from foot length
Measure your child's foot (or yours) and find the right European shoe size.
How it works
European sizes (Paris points) are 2/3 cm each: size = (foot length + allowance) × 1.5. Measure standing up, at the end of the day, from heel to longest toe. Young children's feet grow about one size every 3 to 4 months: check often.
