The women's grid ends at 280 mm and EU 43, past which supply moves almost entirely to large-size specialists and men's or unisex ranges.
UK to US conversion
Women's UK sizes run two numbers below US, a wider gap than the one-size men's offset, so UK 6 is US 8 and UK 8 is US 10 the whole way. The two points a US number sits above the UK one never change across this scale, which makes the pair a clean fixed step. That steadiness is why a UK-bought shoe converts to US by adding two with no rounding, unlike the shifting EU conversions.

Frequently Asked Questions Does UK 9 round up or down in US? EU 43, US 11 and UK 9 are whole numbers, so even at the top of the scale the conversion is exact; a foot just over it belongs in a men's or unisex size, not a squeezed 43.
