Looking for a free online shoe size converter? Our footwear size converter helps you convert US men's, US women's, UK, and EU shoe sizes instantly. Whether you need to convert shoe sizes for international online shopping from brands like Nike, Adidas, or Zara, or you simply want to understand what your US size equals in European sizing, this free shoe size converter gives you instant results.
Our shoe size converter works for both men and women across multiple sizing systems. You can convert US men's to UK and EU, convert US women's to UK and EU, and even convert foot length in centimeters to international shoe sizes. The tool supports US sizing (different for men and women), UK sizing (unisex), and EU sizing (unisex Paris point system). Whether you are shopping for running shoes from a European brand, casual sneakers from an American company, or formal shoes from a British retailer, our footwear size converter handles all these conversions instantly.
Understanding international shoe sizing differences is crucial for successful online shopping. US shoe sizing typically runs about 1 size larger than UK sizing for the same foot length. EU sizing uses the Paris point system, where each size represents a precise increment. A US men's size 10 equals approximately a UK 9 and an EU 44. This confusion leads to wrong purchases and expensive return shipping. Our shoe size converter eliminates this confusion by providing instant, accurate conversions.
The tool also supports foot length conversion in centimeters, which is the most accurate way to determine shoe size. If you know your foot length in centimeters from measuring at home or from a professional fitting, you can use our converter to find your corresponding shoe size in US, UK, and EU systems. Many podiatrists and shoe fitting experts recommend using foot length as the primary reference point for finding the correct shoe size.
Our free shoe size converter online is completely private and secure. Your size conversions happen instantly in your browser, and no data is stored or transmitted.

US sizing has separate scales for men and women. Women's sizes are typically 1.5 sizes larger than men's for the same foot length.

Measuring your foot length in centimeters is the most accurate method. Use our converter with your cm measurement for the most precise conversion.

Shoe Size Converter Troubleshooting
Problem: Converted size doesn't fit
Solution: Shoe sizing varies between brands. A US size 9 in Nike may differ from the same size in Adidas. Use our converter as a baseline and check the brand's specific size guide.
Problem: I'm between sizes
Solution: If you are between sizes, we recommend sizing up for closed-toe shoes and boots. For sandals and casual shoes, consider your preference for a snug or loose fit.
Problem: Half sizes not working correctly
Solution: Not all sizing systems use half sizes. EU sizes, for example, use whole sizes only. Our converter rounds to the nearest practical size.
Problem: My foot length doesn't match any size
Solution: Measure your foot length carefully from heel to longest toe. If between sizes, round up to the nearest whole or half size for comfort.
Problem: Children's sizes not supported
Solution: This converter is designed for adult shoe sizes only. Children's sizing uses different formulas and scales that are not included in this tool.
Problem: Width not accounted for
Solution: Our tool converts length-based sizing only. Foot width varies independently of length. Look for brands offering wide or narrow options if needed.
