A 210 mm foot is the smallest size the women's grid carries, below where most European ranges begin and into territory shared with older girls' shoes.
Brand fit: EU 34 sits on a last up to 1.5 cm longer than the 210 mm foot, so Japanese 21.0 cm tracks the foot itself while EU brands differ by the last length added.
Availability: Women's 210 mm is stocked thinly in the West and more reliably in Japan and Korea, where 21.0 cm is a standard adult size; petite and Asian-market lines are the easiest source.
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.
At this size, UK to US
One size up from UK 2, US moves 0.5 to US 4.5 while UK rises 0.5 to UK 2.5, holding their spacing. Both UK 2 and US 4 are whole numbers here, so nothing rounds. For UK 2, the US column here runs US 4, US 4.5, US 5, stepping a half size at a time.

Frequently Asked Questions Does UK 2 round up or down in US? EU 34, US 4 and UK 2 are all whole here, so a rounding choice is rare; when a foot sits between sizes, the larger one with a snugger lace beats a short toe box.
