Frequently Asked Questions

Why do my shoes feel too tight?

Often it's a half-size or width issue, or the brand runs small. Measure your foot in cm and use our converter; check the brand size chart and consider sizing up for brands that run small.

How do I measure my foot for shoe size?

Measure from heel to longest toe in cm, in the evening when feet are slightly larger. Use our Measurement Assistant or printable foot measuring sheet, then the shoe size converter.

What if my US size doesn't match EU?

US and EU use different scales. Use our Shoe Size Converter: enter your US size and gender to get EU, UK, and other equivalents. Don't assume the number is the same across regions.

Common questions

How should I use this converter?

Pick your region and size, then read the equivalents. When in doubt, measure in centimeters and compare to the brand chart.

Why do sizes differ between countries?

Each region uses its own scale; mapping through foot length (cm) reduces error.

Why Sizes May Vary
