Input basis
Brand last shape and gender scaling can shift the recommended size by ±0.5–1. Treat as a starting reference, not a fit guarantee.
How to use this result
Korean shoe sizing uses foot length in millimeters as the base unit. International conversion tables use that millimeter length as the anchor.
Brand-specific lasts and gender scales shift the recommended size by roughly ±1, especially for athletic and dress shoes. Treat the converted value as a starting reference, not a guarantee.

Common questions
Q.Why do brands differ?
Last shape, toe-box volume, gender-specific scaling, and country-specific conventions can shift the recommended size by half to a full size.
Q.Are men, women, and kids the same?
No. US sizes split by gender and kids use a separate scale, so the same Korean millimeter value maps to different US numbers depending on the category.
