How to use direct shoe size converters
Shoemakers worldwide use different mathematical bases. American and British systems measure length using the barleycorn (one-third of an inch), European manufacturers build lasts based on the Paris Point (two-thirds of a centimeter), and Asian countries use metric measurements in centimeters or millimeters.
When shopping online across borders, whether purchasing sneakers from American distributors, boots from Italy, or footwear from India, relying on a direct converter accounts for length increments and gender offsets.
Tips for international conversions
- Check footbed length in centimeters when a brand tag includes CM or JP sizing.
- In the European system, an EU 42 is identically sized whether made for a man or a woman.
- Allow approximately 1.0 cm to 1.5 cm of toe room beyond your measured foot length when choosing enclosed boots or running shoes.
