We don't sell cheap products, we don't sell expensive products, we only sell the most cost-effective products. Note: There may be slight color difference when taking photos. Please forgive me. The color of the product is subject to the actual product. The package that is easy to transport is a plastic bag. Not a shoe box! If you need shoe box packaging, you need to add 3 USD freight. We do not bear the taxes of your country. Thank you for your understanding. Size: Currently, there is no unified size worldwide. European size is not equal to Chinese size. Measure the length of the feet before purchasing. (Note: Do not directly measure the length of the foot and the length of the insole, as this can cause errors. Please place the foot on white paper and use a pen to draw the front and rear ends of the foot on the paper.) For example, if your foot is 25 centimeters long, please choose 25 centimeters. If your leg is wider or obese, it is recommended to+0.5 centimeters (for activity space),please choose 25.5 centimeters.
