The Superbuy Size Master Spreadsheet

At the core of this innovation lies Superbuy's proprietary global size conversion matrix, which aggregates:

  • 38 countries' footwear size standards (including Japan's JIS and Brazil's BR/FR systems)
  • 1.2 million historical purchase records
  • Regional foot morphology data

Case Study: Japan-to-US Size Conversions

When a Tokyo customer selects US size 9 Nike Air Force 1, our system instantly:

  • Triggers a translucent popup reading: "Most Japanese customers prefer US 8 for this model - watch our lace measurement guide"
  • Displays an embedded video demonstrating thumb space testing
  • Highlights width difference between Asian (D) vs. American (D) lasts

    • The Predictive Returns Protocol

    Superbuy's logistics AI identifies high-risk transactions using:

    Region Return Rate Intervention Protocol
    South America 22% Prepaid return labels + Size guarantee upsell*
    Middle East 17% GIF tutorials for sandal sizing†
