1.Dear cistomer, please choose the size according to your foot length (Please Don't choose size according to your country usual size) 2. Foot length ≠ insole length ≠ outsole length. For Example: US 4.5(25.5cm). This 25.5CM means insole length only . 3.Better to choose 1-2 size bigger if your foot is a little wideer or instep is a little thicker. 4.Light, camera and displays can cause color difference. please take this into consideration while you are shopping. 5.Please allow 0-0.5cm error for the size of the shoes. 6. If you have any questions or feedbacks, please let us know and contact us. We wish you a happy shopping experience. 7. Have a nice day :)
