EU 40 in women's shoes tops out many European ranges, where 40 or 41 is the largest size a mainstream line cuts before switching to a large-size label.
Brand fit: On EU 40 the German width ladder spans F at 23.3 cm to J at 24.7 cm girth, so Ara and Finn Comfort can build this 255 mm size on a different letter.
US to EU conversion
A women's US size plus 30 to 32 gives the EU number, the gap creeping up one point as the foot lengthens, so US 6 is EU 36 and US 10 is EU 42. Because EU counts smaller steps, a US half like 6.5 falls onto a whole EU 37, and the offset you use at US 5 is a number short by US 10. Reading the EU figure a brand lists avoids the drift, which is why converted charts disagree most at the top of the women's range.

Frequently Asked Questions Does US 8.5 round up or down in EU? US 8.5 and UK 6.5 are halves while EU 40 is whole, so an EU start rounds nowhere; between sizes, the larger with a snug lace holds better than the smaller.
