Why US and EU pull apart as sizes climb
The distance between US and EU is not fixed: it widens from 31 at the small end of the chart to 35 at the top, so no single subtraction converts every size. Reading across the row is safer, and there US 9 converts to EU 42. That row sits at 270 mm of foot length, the measurement both national numbers are trying to describe.
US shoe numbers grow from the barleycorn, an old English third of an inch, while the European number counts the shoe's last in Paris points of two thirds of a centimetre, near 6.67 mm. The two units were fixed for different trades and never lined up, so the space between them stretches as feet get longer. Last shape widens the split again: the last is cut up to 1.5 cm longer than the foot, and each maker adds its own amount, so the same US 9 can print a slightly different EU number from Nike, adidas or New Balance.
Common questions
Is the EU size just the US size plus a fixed number?
No. The gap changes as sizes climb because the two scales count in different units, so the table above is the only safe reference for a whole range.
Why do EU numbers differ between shoe brands?
The EU number describes the last the shoe is built on, and every brand cuts that last a little longer or shorter than the foot, so a half-number of disagreement between labels is normal.
