Convert shoe sizes and create a resale listing note
Shoe buyers often compare US men, US women, UK, EU, and CM/JP labels before purchasing used footwear. The converter maps the labeled size to a New Balance adult chart baseline, then adds brand caveats for Nike CM labels and adidas fractional EU sizing.
The tool is built for reseller listings, not fit promises. The output includes a copy-ready listing note with the label size, approximate conversions, and measured insole field. That helps answer buyer size questions while avoiding a claim that conversion alone guarantees fit.
Use the chart with real shoe evidence: tag photo, box label, brand model, width, condition, and an actual insole or outsole measurement. Worn shoes can fit differently from the original chart because of model shape, width, age, and wear.
- Inputs resellers have: label system, printed size, brand, and optional measured insole in centimeters.
- Output decision: exact chart match, nearest chart row, or low-confidence conversion needing more evidence.
- Risks prevented: wrong men/women conversion, missing UK/EU/CM context, Nike CM overclaiming, and fit disputes from no measurement.
- Best follow-up action: include a tag photo and real insole or outsole measurement in the listing photos.

Frequently Asked Questions
Are men's and women's shoe sizes interchangeable?
No. US men and US women are separate systems. A common adult athletic conversion is about 1.5 sizes apart, but use the brand chart and a real measurement instead of copying one system into the other.
Should I include EU, UK, and CM in a resale listing?
Yes when the shoe label or brand chart supports it. Multiple systems help buyers compare sizing, but conversions should be described as approximate unless the exact label shows those values.
Why does the tool warn about Nike CM sizing?
Nike notes that the CM size shown on boxes and labels differs from Foot Length in centimeters. For Nike listings, do not present the label CM value as a measured insole length.
What size evidence reduces shoe returns?
Use the labeled size, tag or box photo, brand/model, width if shown, approximate conversions, and an actual insole or outsole measurement. The measurement matters most for used shoes because wear and model shape can affect fit.
