When to trust CM more than EU, US or UK
CM is usually the safest cross-brand reference because it is tied to foot length. EU, US and UK are labels, and brands can map those labels differently across gender lines and product families.
If CM and a familiar label disagree, use CM first, then confirm the exact product page before buying.
How to avoid returns
Start from a shoe that already fits, compare the target brand row, check width and read model notes before checkout. Most sizing mistakes happen when shoppers rely on a single EU or US label and skip the model context.
Read the return checklistWhy size charts differ
Brands use different lasts, materials and fit goals. A running shoe, canvas sneaker and retro basketball shoe can share a label while fitting differently.

Not sure what your size means in another system? Here’s how the most common sizing standards work - and why they sometimes differ between brands.
EU sizing
The most common system in Europe - often similar, but not identical across brands.
US sizing
Separate men’s and women’s scales - conversions vary by manufacturer.
UK sizing
Used widely in the UK - typically differs from US by about 1 size, but brand charts matter.
CM / JP sizing
Based on foot length in centimeters - great if you know your measured foot length.
Inches / IN
Calculated automatically from CM. Useful when you compare foot or insole length in imperial units.
How to measure foot length (in CM)
For the most accurate result, measure your foot from heel to toe and use the CM value as your reference.
Where our size data comes from
Whenever possible, we use official brand size charts. When a brand doesn’t provide a complete mapping, we show an approximation and label it clearly.
Official
Directly from the brand’s published chart
Approx
Derived conversion, marked as approximate
Missing
No reliable mapping yet (we’ll show what’s missing)

Read methodologyFAQ
Are shoe sizes the same across brands?
No. Even if two brands use the same “EU 42”, the fit can differ due to lasts, materials, and brand sizing rules.
Why do men’s and women’s US sizes differ?
US men’s and women’s scales are different. Always pick the correct gender chart when converting.
Is CM sizing the most accurate?
Often yes - CM is based on foot length. It’s a strong reference when moving between brands.
What does “unisex” mean in sizing?
Unisex usually follows a men’s scale, but it depends on the brand. We label the chart type when known.
Why do some conversions show “Approx”?
Some brands don’t publish full conversions. In that case we provide an approximation and mark it clearly.
