Why cm wins: US, UK and EU numbers are labels, not measurements, and each brand stretches them differently. Your foot length in centimetres is the one number that never changes — measure it with our step-by-step guide, then read across the chart.

Frequently asked questions

Is a US 10 the same in the UK?

No. A men's US 10 converts to a UK 9.5 in the general chart, and a women's US 10 converts to a UK 8. Always convert — never assume the number carries over.

What EU size is a US 9?

For men, US 9 = EU 42.5. For women, US 9 = EU 39.5. The same US number means different EU sizes for men and women, which is why the converter asks for the category first.

Why did the converted size not fit?

Conversion charts describe length only, and brands cut their lasts differently — a converted size is a starting point, not a guarantee. Width, toe shape and model all matter. When between sizes, most people do better sizing up for sports shoes and down for dress shoes.

How do I convert from centimetres?

Measure your longer foot in the evening, heel to longest toe. Then find that cm value in the chart: 28 cm = men's US 10 / UK 9.5 / EU 44; 25 cm = women's US 8 / UK 6 / EU 38.5.
