Fit notes for this size
- The step to the next size. Going up from EU 47.5 to EU 48.5 buys you 0.8 cm, from 30 cm to 30.8 cm. That is the normal step for this part of the chart. Going down to EU 47 takes 0.4 cm off, to 29.6 cm.
- If you measured between sizes. This row is built for a 30 cm foot. A foot measuring more than 30.4 cm sits closer to EU 48.5 than to this one, so take the larger size rather than hoping the shoe stretches.
- The same foot in socks. A 30 cm foot falls in sock size XL (29.5 to 31.5 cm), which is US men's 12.5 to 15and US women's 13.5 to 16 on the sock size chart. Sock bands are wider than shoe sizes, so a foot near the edge of the band fits either neighbour depending on the knit.
The reverse conversion
Going the other way, US men's 13 or women's 14.5 comes back to a foot length of about 30 cm, the same shoe with a different label on the box. See US shoe size in cm for that direction in full.
Why the numbers differ
Every size on this page describes the same physical foot length, 30 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.
Because you are starting from a measurement rather than a size label, this is the most reliable direction to convert in. Measure the longer foot, standing, with the heel against a wall, and compare that number to the foot length column. Shoes are normally built with roughly half a centimetre of room beyond the foot, so if your measurement sits between two rows take the larger one. To measure properly, see how to measure shoe size. For every other size in this direction, see the full cm to US shoe size chart.
Common questions
What shoe size is 30 cm in US?
A 30 cm foot is a US men's 13 or a women's 14.5, the standard size built for exactly that length.
Is 30 cm the foot length or the shoe length?
It is the foot length. Shoes are built longer than the foot they fit, usually by about half a centimetre to a centimetre, so a 30 cm foot goes into a shoe whose internal length is a little more than 30 cm. The chart on this page is anchored to foot length throughout.
What is 30 cm in the other systems?
A 30 cm foot is UK 12.5, EU 47.5, a US men's 13 and a US women's 14.5.
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.
