Sizing varies more than you'd think
These conversions are the canonical "standard" mappings, but every shoe brand picks its own size scale. Two pairs of US 10 sneakers from different brands can differ by half a size or more. The number you get here is a useful estimate, not a guarantee.
The foot length is the truth
The most reliable measurement is the actual length of your foot, in cm. If you can measure that and a shoe lists a cm/mm sizing, you'll get a much more accurate fit than any number conversion.
