How to measure your child's foot
- Place a sheet of paper on a hard floor with one edge against a wall.
- Have your child stand with their heel touching the wall, weight on that foot.
- Mark the tip of their longest toe, then measure heel-to-toe in centimeters.
- Measure both feet and use the larger measurement. Between sizes? Size up.
Frequently asked questions
How do I measure my child's foot for Adidas shoes?
Stand your child on paper with their heel to a wall, mark their longest toe, and measure heel-to-toe in cm. Use the larger foot, and match that length to the foot-length column in the Adidas chart above. If they're between sizes, size up.
What age is each Adidas kids' size for?
Sizing by age is only a rough guide because children's feet grow at different rates — always go by measured foot length. Adidas kids' shoes top out at US 7.5 (about 25 cm / EU 40⅔). For larger feet, switch to the adult Adidas size chart.
