Shoe size conversion is the process of translating a shoe size from one country's or region's sizing system into another. Different countries use different systems for measuring feet and assigning shoe sizes, so a size 9 in the US, for example, won’t be the same as a size 9 in the UK or Europe.

Here are a few key things to know:
US sizes: Separate charts for men’s, women’s, and children’s shoes.
UK sizes: Typically about one size smaller than US sizes for men.
EU sizes (continental Europe): Measured in Paris Points (about ⅔ of a centimeter).
Japan sizes: Based on the length of the foot in centimeters.

For example:
A US men’s size 10 = UK men’s size 9 = EU size 44 = Japan size 28.

Since sizes can vary a bit between brands and styles, it’s always a good idea to try shoes on if you can, or check the brand’s own size chart. Want me to help convert a specific size?
