About the shoe size converter
Sizing is taken from common US/UK/EU/CM conversion charts, where CM is the approximate foot length the size is built for. Brands differ, so treat the result as a starting point and measure your foot when you can. Everything runs in your browser and nothing is uploaded.
Questions
Is anything uploaded?
No. The conversion uses built-in charts and runs entirely in your browser — nothing is sent or stored.
Why is CM shown as foot length?
CM (also called Mondopoint) is based on the length of your foot in centimetres, which makes it the most reliable way to compare sizes across regions and brands.
Why do brands still fit differently?
These are standard reference charts. Real-world fit varies by brand, last shape and style, so use the result as a guide rather than a guarantee.
