Simply measure the length of your child's foot (with their foot ''standing'' on a flat surface) and add 0.5-1cm growth room. Then match that measurement to the size you need. An age range is given for each size, but remember every pair of baby feet is different!

If your child measures between two sizes, we do recommend you chose the larger size as they will grow into them.
