Mexico to US Shoe Size
Check whether an MX value is a label or a measured foot length; use the seller’s actual matching US row.
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.

| 22 | 4 | 5.5 | 3.5 | 36 |
| 22.5 | 4.5 | 6 | 4 | 36.5 |
| 23 | 5 | 6.5 | 4.5 | 37.5 |

Mexico to US: a verified MX-label lookup
On adidas Mexico's adult footwear chart, MX 7 is US Men's 9 (and US Women's 10); the same adidas row lists a 26.3 cm measured foot. This is a brand-specific MX size, not a blanket formula for every Mexican retailer.
Check whether a listing shows adidas-style MX numbers, a measured foot length in centimeters, or an imported US size. The general US/UK/EU chart above does not contain an MX column; use the manufacturer's MX-to-US table for the final choice.
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.
