Aetrex, the New Jersey based global leader in foot scanning technology and data driven footwear, has hit a major milestone with its FitAI technology, surpassing 2 million recommendations for shoppers across more than 500 retail locations worldwide. Now adopted by over 100 global retailers, including ASICS, PUMA, DSW, and Fit2Run, the technology is redefining how consumers find the right shoe fit both in-store and online.
What FitAI Actually Does
FitAI uses proprietary 3D foot scanning hardware and AI software to match a customer’s unique foot shape against a database of 3D scanned footwear by brand and style, delivering fit ratings that range from “excellent” to “poor.” The process begins with a scan using either an Albert Pro or Zoe Pro device, after which the software instantly displays personalized fit recommendations from the retailer’s available inventory. Once a retailer accumulates 5,000 foot scans to purchase data points, FitAI can also be activated online, allowing returning shoppers to receive personalized recommendations directly on the retailer’s website.
Larry Schwartz, CEO of Aetrex, said, “Our goal when we set out to create Aetrex FitAI was to equip sales associates with a tool to guide consumers to the right shoe fit for their unique feet, effectively building purchase confidence and promoting better foot health. The result is a data-driven complement to the traditional sales associate interaction, offering a more detailed and consultative engagement that elevates the retail experience both in-store and online, enhancing brand loyalty.”
Retail Partners Are Seeing Real Results
The numbers coming from FitAI retail partners are hard to ignore. The platform delivers an average customer engagement rate of 45 to 60%, and shoppers who interact with it are 5 times more likely to return for a new purchase than traditional retail shoppers.
John Wompey, Chief Operating and Customer Officer at Fit2Run, said, “FitAI enhances our store’s premium, end-to-end fit experience. The program extends beyond the store. Its accuracy and ease of use drive customer loyalty — shoppers are five times more likely to return for a new purchase — while seamlessly integrating the in-store and online journey for a smooth, streamlined, elevated shopping experience.”
How Each Partner Is Using It
The technology is delivering distinct benefits across different retail environments:
- ASICS: Consumers who interact with FitAI show significantly higher marketing opt-in rates than traditional retail shoppers, with international engagement surpassing initial expectations
- Fit2Run: FitAI captures high value customer data during the 3D fit process and activates it through personalized recommendations across in store and online channels, driving repeat traffic and higher lifetime value
- PUMA: FitAI delivers tailored feedback that boosts customer confidence in fit and comfort choices, empowering store associates to highlight specific performance benefits for each shopper’s unique needs
Built on Two Decades of Foot Scanning Data
FitAI did not emerge overnight. Aetrex has been placing 3D foot scanners in retail environments since 2002, with over 12,000 scanners now deployed worldwide and more than 50 million unique foot scans completed to date, currently averaging more than 2.5 million scans per year. That proprietary dataset, stored in the SmartLast database of 3D scanned footwear, is what gives FitAI a depth of fit accuracy that competitors have struggled to replicate. Originally launched in 2023 under the name FitGenius, the platform was rebranded to FitAI to reflect its expanded capabilities across both in store and online channels.
