Gather a piece of paper, a pencil, and a ruler or measuring tape
Have your toddler stand on the paper with heel against a wall
Trace around both feet while the child is standing
Mark the longest toe on each foot
Measure from the heel line to the longest toe mark in inches or centimeters
Measure both feet and use the larger measurement
Add a small amount of growing room if needed
Compare the measurement to a toddler shoe size chart
Check the shoe’s width as well as length
Try the shoes on and make sure there is space at the toe and heel
Recheck foot size every few months
