常见问题

How do I convert US shoe size to UK?
For adults, a UK size is typically 0.5 to 1 size smaller than the US size for the same foot (US men 9 ≈ UK 8.5). Select the US size above and the UK column shows the match instantly.
How do I convert US shoe size to EU size?
EU sizes don't map with a simple formula — they come from last length in Paris points. A US men's 9 is usually EU 42 to 42.5, but Nike and Adidas differ. Use the chart above or, better, your foot length in cm.
What is the difference between US men and US women sizes?
For the same foot length, a US women's size is 1.5 sizes larger than the men's number (men 8 = women 9.5). Width fittings also differ between men's and women's shoes.
Is it better to buy by size number or foot length?
Foot length in cm is the most reliable size when shopping across countries or brands, because every brand's size chart is built from foot length. Measure in the evening for the best fit.
How do kids' shoe sizes work?
US kids' sizes run from about 8K to 13.5K, then continue as Youth 1Y to 7Y. UK kids' sizes are similar but offset, and after UK 13.5 the UK scale restarts at adult 1. Use the Kids tab above for exact matches.
什么是鞋子的中国码（CN）？如何换算？
中国采用 GB/T 3293.1 标准：鞋码即脚长的毫米数，以 5mm 为步长——CN 265 对应 26.5cm 脚长（约合美码男 9）。在上方选择"中国码（CN）"即可与 CN 码相互换算。
