Attention please
1.If you have any dissatisfaction and questions, please contact our customer service first, we will help you resolve it. 
2.Choose the size according to your foot length (don't choose the size according to your country's usual size!)
3. Foot length≠ insole length≠ outsole length,eg USA 4.5(25.5cm). This 25.5cm is the length of the media insole only.
4. Better choose 1-2 size larger if your foot is a little wide or chest is a little thick.
5. Light and camera equipment and monitors may cause color difference. If you are worried then please don't pay. Thanks.
6. Allow 0-0.5cm size error due to manual measurement.
