The reverse conversion
Going the other way, EU 45.5 comes back to US 13, the same shoe with a different label on the box. See EU 45.5 to US for that direction in full.
Why the numbers differ
Every size on this page describes the same physical foot length, 28.8 cm. Europe measures in Paris points, where one size is two thirds of a centimetre, which is why EU numbers climb faster than UK and US numbers. The UK and the US both use the barleycorn system, a third of an inch per size, but they start counting from different points, and the US then splits again into separate men's and women's scales about 1.5 sizes apart. None of that changes the shoe, only the number printed inside it.
Brands still cut a given size generously or tightly, so treat the converted number as the starting point and the 28.8 cm foot length as the check. If a retailer publishes an internal length or an insole length, compare that to your own measurement rather than trusting the size label alone. To measure properly, see how to measure shoe size. For every other size in this direction, see the full US to EU shoe size chart.
Common questions
What is US 13 in EU shoe size?
A US men's 13 shoe is an EU 47.5 at a foot length of 30 cm, and a US women's 13 is an EU 45.5 at 28.8 cm.
Is US 13 a men's or a women's size?
It can be either, and they are not the same shoe. A US men's 13 fits a 30 cm foot and a US women's 13 fits a 28.8 cm foot, a difference of about 1.2 cm. Check which scale the retailer is using before you order.
What is US 13 in UK and EU?
A US men's 13 is UK 12.5 and EU 47.5. A US women's 13 is UK 11 and EU 45.5. UK and EU use one number for both men and women, so there is no split on that side.
What if I am between two sizes?
Size up. A shoe that is slightly long stays wearable with a thicker sock or an insole, while a shoe that is too short cannot be fixed. Foot length also increases through the day, so measure in the afternoon.
