How to Measure Your Foot for CN Shoe Size
- Prepare the Materials: You’ll need a piece of paper, a pencil, and a ruler or measuring tape.
- Trace Your Foot:
- Place the paper on a flat, hard surface.
- Stand on the paper with your heel against the wall.
- Trace around your foot, keeping the pencil perpendicular to the paper.
- Measure the Length:
- Measure from the back of your heel to the tip of your longest toe in millimeters.
- Record the measurement.
- Compare to CN Size Chart:
- Use the CN size chart to find the corresponding CN size based on your foot length.
Additional Tips
- Measure Both Feet: One foot may be slightly larger than the other. Use the measurement of the larger foot.
- Measure at the End of the Day: Feet can swell throughout the day, so measure in the evening for the most accurate size.
- Consider Width: Some people may need a wider or narrower shoe depending on the shape of their feet.
By understanding CN shoe sizes and how they convert to US and EU sizes, you can confidently purchase shoes from Chinese manufacturers or when shopping internationally.
