About Shoe Size Converter

Welcome to Shoe Convert, the most accurate shoe size conversion tool on the web. Our mission is to help shoppers around the world find their perfect shoe size, no matter where they're shopping from.

Our Approach to Accuracy

Unlike many other conversion tools, our shoe size converter is based on the ISO 19407:2023 standard (Footwear - Sizing - Conversion of sizing systems). This international standard provides the technical specifications for converting between different shoe sizing systems.

We've implemented both the mathematical formulas from the standard and reference tables for common sizes to ensure the highest level of accuracy in our conversions.

Why Shoe Sizes Matter

Finding the right shoe size is crucial for comfort and foot health. Ill-fitting shoes can cause blisters, calluses, and even long-term foot problems. When shopping internationally, understanding size conversions becomes even more important.

Our Data Sources

Our conversion data is compiled from:

  • ISO 19407:2023 standard formulas and tables
  • Official brand size charts
  • The Brannock Device measurement system

We regularly update our conversion tables to ensure they remain accurate and reflect any changes in international standards.
