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.
