US shoe size 11 to Chinese
Select whether US 11 means men’s or women’s. The named adidas reference reports its own EU-style label and foot length; other brands can differ.

Reference: adidas adult footwear. For other brands use their own chart. Confirm whether a seller’s CN label uses millimetres or EU-style numbering.
Which Chinese size should I look for?
US men’s 7.5 corresponds to an adidas EU label of 40 2/3 and a 25.0 cm heel-to-toe chart value. A seller may call the EU-style number “CN”, or use a millimetre foot-length label such as 250 instead. Confirm both the sizing system and brand before ordering.
Adult shoe size comparison chart
Read across one row within this adidas chart. These are brand reference values; they do not establish a universal Chinese-to-US formula. “Not listed” means this reference has no women’s value for that row. Scroll the table on smaller screens.

Measure the foot, not the shoe
- Stand with your weight on a flat surface and mark the heel and longest toe.
- Measure that distance on both feet; compare the longer foot with the brand’s instructions.
- Select centimetres, millimetres or inches above. If the length falls between chart rows, the tool shows both neighbours.
Inside length includes space inside a shoe. Selecting inside length converts cm to inches but does not infer a US size. Printed CM/JP labels can also differ from actual foot length: Nike explicitly distinguishes its CM label and foot-length measurements.
Why do other converters give a different answer?
Retail labels vary by brand and men’s/women’s chart. Width, toe shape, socks and the specific shoe model also affect fit. This tool reports exact matches and neighbouring reference rows without promising the shoe will fit. It does not extrapolate outside the supported adult chart or convert children’s sizes with adult formulas.
Reference and checking
The values above come from the adidas men’s and women’s footwear chart, checked 2026-10-15. Use the actual product’s chart if it differs. If the label is ambiguous, ask the seller for the foot-length column and whether their CN label means millimetres or an EU-style size.
