Frequently Asked Questions
What is EU 42 in US shoe size?
EU 42 typically converts to a US men's size 9 and a US women's size 10.5, depending on brand and width — use the converter above for your exact size.
How do I convert US shoe size to CM?

Are UK and US shoe sizes the same?
No. UK sizes are typically about one size smaller than US for the same foot length (e.g. US 9 ≈ UK 8).
Why do shoe sizes vary by country?
Each region built its own sizing system using a different scale — the EU uses a formula based on foot length in cm, while the US and UK use different scales entirely. Comparing foot length in centimeters is the most reliable way to check a size across regions.
How do I measure my foot in cm?
Stand on paper with your heel against a wall, mark your longest toe, then measure the distance in centimeters. Repeat for both feet and use the larger measurement.
