The Air Jordan 1CNfans AJ1 Size Matching Spreadsheet.
The Pain Point of AJ1 Sizing Variations
From 1985 OG cuts to modern Retro High OGs and Mid releases, Jordan 1 models show noticeable discrepancies:
- 1985 OG versions typically fit half-size larger
- Pre-2018 retros run narrow in toe boxes
- Post-2018 "remastered" pairs have standardized lasts
- Special materials (satin, SP editions) alter fit
How the CNfans Database Works
The system leverages multi-source data integration:
- Client Profiles: Collects foot length/width, arch type from 10,000+ buyers
- Historical Match Data: Analyzes 15,000+ successful AJ1 purchases
- QC Calibration: Cross-references factory measurements (3-5mm tolerance)
- Version Matrix: Covers 18 AJ1 sub-models from 2014-2023
The Machine Learning Advantage
Unlike standard size charts, CNfans' algorithm processes three decision layers:
1. Base Fit Prediction
