Jump to your exact EU size
Each size below has its own page with the answer, the neighbouring sizes and the reverse conversion.
EU and US shoe sizes are two labels for the same foot lengths. The chart ties each EU size to its US equivalent through the foot length in centimetres, which is the one dimension that does not change between systems. If you know your foot length, you can confirm both sizes directly.
The lookups people search for most on this route: EU 38 equals US men's 5.5 or women's 7 (23.7 cm), EU 42 equals US men's 8.5 or women's 10 (26.2 cm), and EU 44 equals US men's 10 or women's 11.5 (27.5 cm).
Remember that US sizing splits into separate men's and women's numbers while UK and EU use a single scale for both. When in doubt, convert by centimetres and size up if you fall between two rows. To measure your feet, see how to measure shoe size.
Common questions
What is EU 42 in US?
EU 42 is a US men's 8.5 or a women's 10, a foot length of 26.2 cm. Every other size is in the chart below.
How do I convert EU shoe size to US?
Find your EU size in the chart and read across to the US column, or use the converter above. Every row is anchored to a foot length in centimetres, so the conversion is exact rather than a rule of thumb.
Does EU to US differ for men and women?
Yes on the US side. US men's and women's numbers run about 1.5 apart for the same foot length, so both columns are shown. UK, EU and centimetres are unisex.
What if I am between two sizes?
Size up. A slightly long shoe is more comfortable than one that is too short, and you can adjust the fit with insoles or thicker socks. Measure in the afternoon, when feet are at their largest.
