US 15.5 to EU shoe size
A US women's 15.5 shoe is an EU 48.5, which is a foot length of 30.8 cm. US men's sizing does not reach 15.5, so this is a women's size only.

The reverse conversion

Why the numbers differ
Every size on this page describes the same physical foot length, 30.8 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 30.8 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.

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.
