Hello， my dear friend，
Inner length = foot length + 0.3-0.5CM
Thank you

Pls note:

1.The number marked in the shoe's sole is CN SIZE(ChineseSize). The US size is only convenient for you to do order.

2. Pls allow 0.5cm error due to manual measurement in the size chart.

3. Thecomfortable length is the foot length add about0.3- 0.5cm. So you'd better measure your kid's foot length by rule

4. All the shoes will be shiped without shoes boxes.If you need，you can contact us.
