The conversions on this site are based on widely used industry-standard relationships between sizing systems. However, shoe sizing is not governed by a single international standard. Different manufacturers build shoes on different lasts, so the same nominal size can fit differently from one brand — or even one model — to another.
Treat any conversion here as a strong starting point rather than a definitive answer. Where a brand publishes its own size chart, or prints a foot-length (cm) figure, that information should take precedence over a general conversion.
Foot Size Guide is provided "as is", for general information. We accept no liability for shoes that do not fit, for return postage, or for any other loss arising from reliance on the conversions shown. The decision to purchase, and the choice of size, remain yours.
This site offers sizing conversions only. It does not provide medical or podiatric advice. If you have foot pain or a medical condition affecting your feet, please consult a qualified professional.
