Size Guide
Find the Perfect Fit 🤍
At Addi & Emmy Co., we want every little adventurer to have the perfect fit!
Because every child's feet grow differently, we recommend measuring your child's foot before placing your order rather than selecting a size based on age alone.
How to Measure Your Child's Foot
- Place a piece of paper on a hard floor against a wall.
- Have your child stand with their heel touching the wall.
- Mark the longest point of their foot (usually the big toe or second toe).
- Measure the distance from the wall to the mark.
- Compare your measurement to the insole length in the chart below.
For the best fit, we recommend allowing a little extra room for growth and comfort.
