Performance
Sizing is the top reason footwear gets returned. These are average results across merchants after launching RealSize.
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.

Take a quick scan
The shopper places a standard card for scale and scans from their phone camera. Guidance on screen keeps the angle right.

See your ideal size and measurements
RealSize returns the recommended size for that style, how it fits across the foot, and the measurements behind it.

Buy the size that fits
The recommended size is pre-selected on the product page, so the shopper adds it to cart with confidence.

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.

Merchant dashboard
See usage, conversions, AOV and conversion rate from shoppers who scanned. Metrics come straight from your GA4 account, and you can find all of your analytics anytime in your ReaLift dashboard.
