1. CHN 275 indicates a Chinese shoe size of 27.5 centimeters.
2. The conversion between shoe sizes and centimeters follows the rule: foot length (cm) multiplied by 2 minus 10 equals European sizing, while (European sizing plus 10) divided by 2 gives the centimeter measurement.
3. For instance, a Chinese shoe size of 230 millimeters, or 23 centimeters, converts to a European size of (23 x 2 - 10) = 36, meaning 23 centimeters equals European size 36.
4. Centimeter measurement minus 18 plus 0.5 equals US sizing, and US sizing plus 18 minus 0.5 gives the centimeter measurement. For example, a Chinese shoe size of 235 millimeters, or 23.5 centimeters, converts to a US size of (23.5 - 18 + 0.5) = 6, inclusive of half sizes, meaning 23.5 centimeters equals US size 6.
5. The shoe size corresponding to Li-Ning CHN 275 is 45, which is the standard for Chinese sizing.
6. The abbreviations CHN, USA, and EUR in shoe sizes denote the sizing standards of China, the United States, and Europe, respectively, and are commonly used to indicate the sizing systems of different regions.
7. The CHN and CM shoe size conversion table translates centimeters into millimeters, which corresponds to the updated Chinese shoe sizing system.
8. The correct size should be 44 2/3, which may vary depending on the specific model and brand of the shoe.
9. The shoe's external length is typically indicated by JP, and if it is 285 millimeters, the internal length in Chinese sizing (CHN) would be 275 millimeters.
