A US women’s size 10 shoe typically converts to Korean size 270mm or Chinese size 43 (EU). For men, US size 10 is Korean 280mm or Chinese 44 (EU). This is the quick answer straight from the Soudangkou wholesale market stalls.
Why Size Conversion Matters for Wholesale Buyers
When you’re sourcing shoes from China or Korea, getting the size right is critical. A wrong size means dead stock. At the wholesale markets in Guangzhou (like Soudangkou), we handle this every day. Here’s the breakdown.
US Size 10 to Korean Size
Korean shoe sizes are in millimeters (mm). US women’s size 10 = 270mm. US men’s size 10 = 280mm. Note: Korean sizes run slightly smaller than Chinese for the same EU number. Always check the insole measurements before bulk buying.
US Size 10 to Chinese Size
China uses EU sizing primarily. Women’s size 10 = EU 42-43 (typically 43). Men’s size 10 = EU 44. But here’s the trick: Chinese batch sizes can vary by 1-2 mm. When I pick stock for clients, I physically press the sole—stiffness and arch support vary between factories.
At this point, you might wonder about half sizes. Most Chinese and Korean shoes skip half sizes. Size 10.5? Round up to 11 (Korean 285mm, China EU 44).

Practical Tips from a Wholesale Market Insider
When you’re at a stall, don’t just ask for the size number. Grab the shoe and feel the toebox. A US10 foot needs space. Many Asian-made shoes have a narrower fit. Check the stitching along the sides—double stitching means durability. For leather shoes, press the toe: good quality snaps back.
I’ve been sourcing for years. The best trick? Bring a pair of socks that match the thickness you’ll wear. Slip your foot into the display shoe. If it’s snug, go up a size. Chinese factories often produce shoes in batches that fit exactly to EU labels, but leather stretches, synthetics don’t. So for synthetic, always size up.
One more thing: countries like Korea and China use different lasts (molds). A Chinese 43 might feel like a Korean 270, but the volume could differ. If you’re buying for resale, offer size 43 (women) and 44 (men) as standard, but note it’s US10 equivalent. Customers appreciate knowing it’s comparable to a US10.
At Soudangkou, we’ve seen every size mistake. The key is: get the insole measurement in mm. If a shoe says 270mm, that’s an actual 270mm insole. That’s your safety net. Always cross-check with the foot length of your buyer.
To wrap up: US women’s size 10 = Korean 270mm, Chinese 43 (EU). US men’s size 10 = Korean 280mm, Chinese 44 (EU). Half sizes go to the next full size. And when in doubt, measure the insole. It’s the only truth.
