The golden rule when buying shoes from China: Chinese shoe sizes are based on foot length in millimeters—not European or US standards. Always measure the insole length in cm (usually labeled inside the shoe) and match it to your own foot length + 0.5–1 cm allowance. For wholesale buyers, this means you must request a size chart from the supplier and verify by ordering samples before bulk purchase.
China Shoe Size Conversion: The Basics
Chinese shoe sizes often correspond directly to foot length in cm. For example, size 39 (EU) or 8.5 (US men’s) is roughly size 39 in China, but insole length is the safest bet. Here’s a quick reference:
| Foot Length (cm) | China Size | EU Size | US Men’s |
|---|---|---|---|
| 24.5 | 39 | 39 | 7 |
| 25.0 | 40 | 40 | 7.5 |
| 25.5 | 41 | 41 | 8 |
| 26.0 | 42 | 42 | 8.5 |
| 26.5 | 43 | 43 | 9 |
Wholesale Market Tricks for Sizing Accuracy
When buying from Chinese wholesale markets like Soudangkou or Yiwu, follow these steps:
1. Always Ask for the Insole Measurement
Don’t rely on size labels. Request the exact insole length (in cm) from the supplier. Most stalls will provide it if you ask professionally. At Soudangkou, sellers often have a standardized chart per style.
2. Order Samples First
Never skip sample ordering, especially when dealing with market stalls. Pay for one pair per style to verify the sizing, stitching, and material. This also builds trust.
3. Check the Last (模具)
Chinese factories use different lasts for different markets. Ask if the shoe is made for European/US feet (wider) or Asian feet (narrower). If it’s for domestic China, expect a narrower fit.
4. Understand Labeling Variations
Some Chinese manufacturers use EU numbers even for domestic shoes. But the actual size may be off by half a size. Cross verify with the insole.
Common Sizing Mistakes & How to Avoid Them
- Mistaking number for CM: China size 40 is not 40 cm—it’s 25 cm foot length.
- Ignoring width: Request width data (E, D, etc.) if needed.
- Trusting brand sizing: Branded Chinese shoes like Li-Ning use standard sizing, but generic wholesalers vary.

Final Tip for Buyers
When dealing with wholesale markets like Soudangkou, remember that price negotiation often includes sizing flexibility. Some stalls offer to adjust lasts for large orders (MOQ 500+ pairs). So if you spot a great design but sizing seems off, ask about customization. Suppliers there handle overseas orders daily—they know how to adapt.
