Asics kids' shoe size chart

Asics publishes a single youth shoe size range. The 'K' prefix marks kids' sizes (K10–K13), which then continue into 1–7. Match your child's foot length (cm) to the CM column.

How to measure your child's foot

  1. Place a sheet of paper on a hard floor with one edge against a wall.
  2. Have your child stand with their heel touching the wall, weight on that foot.
  3. Mark the tip of their longest toe, then measure heel-to-toe in centimeters.
  4. Measure both feet and use the larger measurement. Between sizes? Size up.

Frequently asked questions

How do I measure my child's foot for Asics 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 Asics chart above. If they're between sizes, size up.

What age is each Asics 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. Asics youth shoes top out at US 7 (EU 40, 25.5 cm). For larger feet, switch to the adult Asics men's or women's size chart.
