Size Guide To find the right size for your child, please select the size according to your child’s foot length and add some extra space for the foot to grow. However, we recommend that you do not calculate too much room for growth in when determining the correct size for your child. Rain boots are naturally meant to fit a little looser than other shoes, but not too loose as it is not possible to strap the foot in.
