Before RealSize

Shoppers are left with poor options for finding their size online:

  • Pick their usual size and hope it fits.
  • Order two or three sizes and return the rest.
  • Answer a quiz-style size finder they don’t trust.
  • Trace their feet with a pencil and paper.

68.8% of footwear shoppers choose to buy in-store because sizing online is hard.

After RealSize

Shoppers get the right size for their feet and fit preference the first time.

  • A 30 to 60 second scan in the browser.
  • A size recommendation for the exact style they’re viewing.
  • Less than 0.01% of shoppers contact support about the experience.

Technology

Computer vision measures the shopper. Machine learning maps those measurements to how each of your styles actually fits.

Click the button to find your size

A “Find your size” button sits next to the size selector on each product page.

What the model reads

Every scan captures 18 foot measurements plus the shopper’s fit preference, then compares them against your size charts and lasts. Brands that run large or small get calibrated, not averaged.

Footwear and gloves

One scanning flow covers shoes, boots, cleats, heels and gloves. Phenom used RealSize to learn their cleats ran larger than other brands, and the recommendations adjusted for it.
