Quick Answer: Shoe Size 40 in China
A Chinese shoe size 40 corresponds to approximately a US men’s 7.5 or women’s 8.5, EU 40, and a foot length of 25.0 to 25.5 cm (9.84-10.04 inches). This is the standard for mass-market and wholesale shoes, but always check the specific last and brand, as sizing can vary.
Understanding Chinese Shoe Sizing
China uses a metric system based on foot length in centimeters. Unlike US or UK sizes, which can be inconsistent, Chinese sizes are more straightforward: size 40 typically means the foot length is 25.0 cm. However, at wholesale markets like Soudangkou, you’ll see a mix of European (EU) and Chinese sizing on labels.

Wholesale Market Insider Tips: Grabbing Size 40 Stock
If you’re sourcing from Chinese wholesale markets—think the bustling floors of Soudangkou—here’s what you need to know.
1. Size 40 is a ‘Gatekeeper’ Size. Factory minimums often start at size 39 or 40. Many stalls will push you to buy a full size run, but you can negotiate for size 40 only if you’re testing a style. Walk the floor and ask three different stalls for their best price on one size. The real players will quote you a unit price plus small batch fee.
2. Check the Insole. Wholesale shoe sizing can deviate by ±0.5 cm from the marked size. Always carry a measuring tape. Pull the insole out—if it’s flimsy foam glued on, expect quality issues. A good size 40 insole at Soudangkou should be about 26.5 cm long (including toe allowance).
3. Feel the Upper & Lining. For leather shoes, press the toe—genuine leather dimples, PU doesn’t. For sneakers, bend the shoe at the ball of the foot. If the mesh wrinkles or the outsole separates, it’s low-grade. Insist on a ‘cut test’—some hot sellers will let you cut a small piece off the tongue to see the real fiber content. That’s how you spot quality in a flash.
