Start with foot length when you can
Measure the longer foot in centimeters, then use the intended footwear maker’s Foot Length or Heel-to-toe chart to select a size. The shared JP/CM column in Sizemapped’s shoe-label tables is not that measured length; it is a printed shoe-size marking.
The same label can fit differently
Last shape, width, toe allowance, socks, and brand grading can all change fit. Generic conversions are useful references, but product-specific charts still matter.
Use foot length to resolve label ambiguity
For labels already printed on shoes, use the generic US/UK/EU/JP/CM chart as a starting comparison only. To choose a new size from a measured foot length, locate the manufacturer’s separate foot-length measurement row; do not treat a JP/CM shoe label as a measurement.
Generic equivalence is a shortlist. The manufacturer chart remains the final reference because brands can grade length and width differently.

These sources support the measurement method and help check real-world variation. They are not presented as one universal brand-size table.
- ISO 19407:2023 — Footwear — Sizing — Conversion of sizing systems — International Organization for Standardization (ISO). Measurement-first footwear methodology and the limitation that cross-system conversions are guidance rather than guaranteed fit.
- Men's Footwear Size Chart — Nike. Manufacturer cross-check showing that foot length, labeled CM values, width, and brand-specific sizing conventions are distinct concepts.
- Footwear Size Guide — adidas. Manufacturer cross-check across heel-to-toe length and US, UK, EU, and Japan-labeled footwear sizes.
