Converting Men’s Shoe Sizes – tips and calculations
Fun fact: There is no hard-and-fast rule to sizing shoes. While we have guidelines and standard practices in the shoe-fitting industry, each brand (and region!) will have different ways of converting shoe sizes.
We encourage everyone to utilize your best tool: the shoes in your closet! Take out a few pairs and see how the sizes compare to average out a good fit.
To convert men’s shoe sizes to international sizes, we can use some general calculations. Assuming we’re starting with a pair of US size shoes:
- To calculate UK size men’s shoes, you subtract .5 from the US size. (Note – some guides say to subtract 1. This is also technically correct, because it depends on the brand.)
- To get to the EU size, you can add around 32 or 33 (we’ve opted for 33)
- To convert US to Japan men’s, you can add 18.
For example, a US 10 is a 9.5 UK size. Or, converting to EU size would be 42.5. And lastly a size 10 would be a 28 in Japan size.
