Ages and Stages Sizing Guide
AGES AND STAGES
A child’s foot is different than an adult’s foot; it is constantly growing and changing. That is why we study children’s feet and carefully consider every detail that goes into a shoe.
All See Kai Run shoes are proportionally engineered for a child’s everchanging and growing foot and designed to promote healthy foot development.

WHEN TO MEASURE
For children 9 - 18 months old,
measure every 2 - 3 months.
For children 18 months - 3 years old,
measure every 3 - 4 months.
For children 3 years old and up,
measure every 6 - 12 months.
HOW TO MEASURE
Using a paper and ruler, have your child stand with their heels against a wall. Make a mark in front of the longest toe and the back of the heel. Use the ruler to measure the distance between the two marks. If your child intends to wear socks, measure with the socks on. Use the chart below to find their size.
CHECK THE FIT
Always check the fit of your child's shoes. There should be about 1/2 inch of room at the toe. The shoe also should not slip off if you pull on the heel.
