Our chart offers a simple way to compare shoe sizes across countries, based on international standards and our fitting expertise. Keep in mind, shoe sizes can vary between styles and brands, even from the same manufacturer.

This chart is meant as a helpful guide, not a guarantee. For the best fit, refer to our expert fitting tools if you're unsure about your size.
