How to Size Your Child's Feet:
- Have your child stand on a piece of paper. Mark the longest points of the foot, from the longest toe to the back of the heel. Measure this distance in centimeters to get the length.
- Allow .5 - 1 cm extra when selecting shoe size, more if the child will wear thick socks with the shoes.
- Measure often - children's feet grow quickly. Measure at least every 2 months during the first year, and every 3 months from 1 - 3 years. You never can tell when your child will have a growth spurt!
