Place a meter or a ruler close to the wall, (important that you start measuring from 0).

Place your child’s barefoot on it, with the heel close to the wall, and check that their toes are well stretched to avoid mistakes.

Take as a reference the measurement where the longest toe reaches and add 3-4mm for the sock or leotard in case of winter-spring footwear.

Once you have that measurement, check in the table which size corresponds to you.
