Frequently Asked Questions
How do I convert my shoe size internationally?
Know your size in one system (e.g., US) and the target system (e.g., EU). Pick men, women, or kids first—the scales differ—then convert.
Is EU shoe size the same as US?
No, EU and US shoe sizes are different. For example, a men's US size 10 is roughly an EU size 43. The EU system uses a different scale based on millimeters.
What is shoe size 42 in the US?
An EU shoe size of 42 is about a US men's 9 and a US women's 11. Confirm with the converter above—half sizes and brand fit still vary.
How does the Chinese (CN) shoe size system work?
The modern Chinese shoe size system is based on the length of the foot in millimeters (mm). For example, a size '265' means the foot length is 265 millimeters. This provides a direct and accurate standard.
Is the old Chinese shoe size the same as EU size?
No, they are often different. The 'old' Chinese system (e.g., size 39, 40) was based on the European (EU) system but manufacturing inconsistencies meant they didn't always match. The old system can be estimated as (Foot Length in CM × 2) - 10.
