US to Mexico Shoe Size
Use the US label to find the manufacturer’s MX entry; use measured heel-to-toe length only with its separate measurement column.
Label comparison, not a foot-length chart. JP/CM is a printed shoe size label; it is not the length of your foot measured with a ruler. For a measured foot length in cm or inches, open the footwear maker's separate Foot Length or Heel-to-toe chart to choose a size. The US/UK/EU references here are approximate and vary by brand.
| JP/CM shoe label | US Men | US Women | UK | EU |

| 22 | 4 | 5.5 | 3.5 | 36 |
| 22.5 | 4.5 | 6 | 4 | 36.5 |
| 23 | 5 | 6.5 | 4.5 | 37.5 |
| 23.5 | 5.5 | 7 | 5 | 38 |
| 24 | 6 | 7.5 | 5.5 | 38.5 |
| 24.5 | 6.5 | 8 | 6 | 39 |
| 25 | 7 | 8.5 | 6.5 | 40 |
| 25.5 | 7.5 | 9 | 7 | 40.5 |
| 26 | 8 | 9.5 | 7.5 | 41 |
| 26.5 | 8.5 | 10 | 8 | 42 |

| 28 | 10 | 11.5 | 9.5 | 44 |
| 28.5 | 10.5 | 12 | 10 | 44.5 |
| 29 | 11 | 12.5 | 10.5 | 45 |

US to Mexico: translate via the seller's MX row
adidas Mexico's chart gives US Men's 9 → MX 7, alongside 26.3 cm measured foot length. The US Women's 10 label occurs on that same published row. The example describes adidas, not a universal Mexican offset.
If your target brand uses different MX labels, start from its US row and read its MX column. Do not treat a 'CM' shoe-box label as identical to a measured foot length.
How to use the general reference chart on this page
The table above compares approximate US men, US women, UK, EU and JP/CM printed shoe-label references. It does not provide a direct country-specific size column. The brand-specific example above supplies a checked local-label answer; confirm it against the actual product chart before buying.
Keep foot length measured from heel to longest toe separate from CM/JP or millimeter numbers printed as shoe size labels. Those may be different quantities even when both contain the unit cm or mm.
How this guidance is checked
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.
- Guía de tallas de zapatos en USA y México — adidas Mexico. Brand-specific MX to US men/women published row and heel-to-toe foot length; not a universal Mexico scale.
