The global e-commerce boom has made platforms like Cnfans
Multidimensional Size Conversion Database
Cnfans’ spreadsheet integrates a dynamic sizing matrix that auto-converts between:- EU sizesUS/UK sizes
- Japanese sizes
Brand-specific last shapes (e.g., Nike Air Max running large or Dr. Martens fitting narrow) are cataloged, ensuring the system accounts for cut deviations beyond standard measurements.
Personalized Fit Recommendations
Shoppers input:
- Exact foot length (in millimeters)
- Width (standard/wide/extra-wide)
- Preferred sock thickness (affects interior space)
The tool then highlights 3 ideal matches from available inventory, ranked by fit precision. Example: A 265mm foot width=normal triggers "US 10 in Adidas Ultraboost (with +5mm toe room)" as the top suggestion.
