A US women’s size 6 is roughly a Chinese women’s size 37-38, while a US men’s size 6 is a Chinese men’s size 38-39. This is the first thing you need to know when buying shoes wholesale from China – because mismatched sizes kill deals.
Shoe sizing in China is based on the metric system (centimeters), so Chinese sizes are often labeled in EU numbers. A US women’s 6 typically corresponds to CN 37 or 38, and a US men’s 6 is CN 38 or 39. But in China’s wholesale markets, the standard ‘size 6’ can be tricky: many local manufacturers use ‘domestic codes’ that don’t match international standards. For example, a ‘size 6’ in some Chinese factories might actually be a women’s 36-37. That’s why you always ask for the insole length in centimeters.
Size Conversion Table: US vs. China
| US Women’s | China Women’s (CN/EU) | Insole Length (cm) |
|---|---|---|
| 6 | 37-38 | 23.5-24.0 |
| 7 | 38-39 | 24.0-24.5 |
| 8 | 39-40 | 24.5-25.0 |
Why You Can’t Trust ‘Size 6’ on Tags
In Chinese wholesale markets like Soudangkou, you’ll see shoes labeled ‘size 6’ that are actually US 8 or EU 39. That’s because some factories use their own numbering system – often based on older Chinese standards. For a US women’s 6, always request CN 37 or EU 37, but verify with the insole measurement. A genuine CN 37 means the insole is about 23.5 cm. If the seller says ‘it’s a size 6’, measure it yourself. We once saw a batch labeled ‘size 6’ that fit like a US 9 – a costly mistake.
Sourcing Tips for Wholesale Buyers
1. Always ask for CM/EU sizes
Refuse to order by ‘US size’ or ‘local size’. Insist on EU or centimeters. Reliable suppliers will provide a conversion chart. If they don’t, walk away.
2. Check the insole and last
Remove the insole and measure it. Also, look at the shoe last (the mold shape). Chinese lasts are often wider for women’s shoes. A US 6 narrow might feel loose in a CN 37. Feel the toe box – if it’s pointy, the size might run small.
3. Inspect materials and stitching
Good leather should feel supple, not plastic. Stitching should be tight and even, at least 8-10 stitches per inch. Check the glue lines – no visible gobs or separation. These are signs of quality that justify higher margins.

Final Advice: Buy With Samples First
Never order bulk from a new supplier without checking a sample. At Soudangkou, stalls offer quick sample purchasing. Pay for the sample, measure the insole, and test the fit. This single step can save you from a container of unsellable shoes. And when you find a supplier with consistent sizing and quality – stick with them. Your customers will thank you.
