Aetrex's AI Fit Tech Hits Milestone, Reshaping Footwear Retail

TEANECK, N.J. – March 17, 2026 – The era of guessing your shoe size may be drawing to a close, thanks to a quiet revolution happening at the intersection of 3D scanning and artificial intelligence. Aetrex, Inc., a global leader in foot-scanning technology, has announced a major milestone for its FitAI™ platform, having delivered over two million personalized footwear recommendations to shoppers. The technology is now a fixture in over 500 retail locations, adopted by more than 100 global brands including industry giants like ASICS, PUMA, and DSW, signaling a profound shift in how the industry approaches its most fundamental challenge: the perfect fit.

At its core, FitAI™ bridges the gap between the unique, complex geometry of a human foot and the hidden internal dimensions of a shoe. By leveraging proprietary 3D foot scanners and a vast database of footwear, the AI-driven system is empowering retailers to boost sales and loyalty while offering consumers newfound confidence in their purchases.

Beyond the Sale: A New Metric for Retail Success

For decades, the footwear retail experience has been a manual, often frustrating process of trial and error. Aetrex's technology aims to replace this guesswork with data-driven precision, and its partners are reporting significant bottom-line impacts. With customer engagement rates holding strong between 45-60%, retailers are seeing benefits that extend far beyond a single transaction.

“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,” said Aetrex CEO Larry Schwartz. “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.”

This elevated experience is manifesting in diverse ways across different brands. At ASICS, shoppers who engage with FitAI show significantly higher marketing opt-in rates, creating a valuable channel for future communication. PUMA has found the technology boosts customer confidence, minimizing the hesitation that often accompanies shopping for high-performance athletic shoes. Meanwhile, specialty retailer Fit2Run, The Runner's Superstore, has integrated the system deeply into its operations.

“FitAI enhances our store’s premium, end-to-end fit experience,” said Fit2Run Chief Operating and Customer Officer John Wompey. He noted that the program's influence extends beyond the store, driving repeat business and seamlessly connecting the physical and digital shopping journey. “Its accuracy and ease of use drive customer loyalty—shoppers are five times more likely to return for a new purchase.”

Similarly, a senior executive at DSW highlighted in a recent discussion how the technology is transforming the shopping experience by significantly reducing returns and improving foot health. With an in-store scan taking as little as 11 seconds, the process builds immediate customer confidence. DSW has even rolled out a specialized "Tootsie" program for children, making the process of finding well-fitting shoes for growing feet an engaging and reassuring experience for parents.

The Anatomy of an AI-Powered Recommendation

The magic behind FitAI lies in a sophisticated, multi-step process that combines cutting-edge hardware and intelligent software. It begins when a customer steps onto an Aetrex scanner, such as the Albert Pro or Zoe Pro, in a retail store. In seconds, the device captures a precise 3D map of the feet, along with pressure points and gait analysis data.

This individual foot data is then cross-referenced with Aetrex’s proprietary SmartLast® database—a massive digital library containing the precise interior 3D scans of thousands of shoe models. The AI algorithm acts as a digital matchmaker, comparing the customer's foot shape to the internal specifications of each shoe in the retailer's inventory. The software then displays personalized fit ratings, ranging from “excellent” to “poor,” for each style.

Recognizing that retailers need a path to adoption, Aetrex developed the FitStarter program. This allows new partners to provide accurate, rules-based recommendations from day one, even before collecting enough data for the full machine-learning model. As the retailer accumulates 5,000 scan-to-purchase data points, the system's AI capabilities are fully unlocked, enabling it to learn from real-world buying behavior and refine its predictions. Once this threshold is met, the service can also be extended online, allowing returning customers to log in and receive personalized recommendations from home.

Standing Out in a Crowded Tech Field

Aetrex is not the only company vying to solve the footwear fit problem. Competitors like Volumental also offer 3D scanning and AI recommendation platforms for retailers. However, Aetrex's deep roots in the industry provide a formidable advantage. Since 2002, the company has placed over 12,000 scanners worldwide, accumulating a staggering 50 million unique foot scans—a data moat that is difficult for newcomers to cross.

This vast historical dataset, combined with its dual identity as both a technology provider and a manufacturer of its own orthotics and comfort footwear, gives the company a holistic understanding of foot health and biomechanics. The SmartLast® database, built by physically scanning the interior of countless shoe models, represents a significant proprietary asset that distinguishes its recommendations from those based purely on external shoe dimensions or user-generated reviews.

The End of "Guess and Check" Shopping

For the consumer, the most significant impact of technologies like FitAI is the shift from anxiety to empowerment. The process of buying shoes, especially online, is often fraught with uncertainty, leading to bracketing—buying multiple sizes with the intent to return most—and general dissatisfaction. By providing a clear, science-backed recommendation, the technology fosters a sense of confidence and trust.

This confidence is directly linked to better foot health, a core tenet of the Aetrex brand. A proper fit can alleviate common ailments and prevent future problems, transforming a simple retail transaction into a wellness-focused interaction. As consumers become more health-conscious, the ability to ensure biomechanical compatibility becomes a powerful selling point.

However, the rise of such powerful personalization tools also introduces important questions about data privacy. The collection of biometric data, such as 3D foot scans, places a significant responsibility on companies like Aetrex and their retail partners. While consumers have so far embraced the benefits, the industry's long-term success will depend on maintaining transparency about how this sensitive data is stored, protected, and used, ensuring that the quest for the perfect fit does not come at an unacceptable cost to personal privacy.

Ultimately, the success of FitAI is a powerful indicator of a larger trend in commerce. The one-size-fits-all approach is fading, replaced by a demand for hyper-personalized products and experiences. By leveraging data not just to sell, but to solve a genuine consumer problem, Aetrex and its partners are building a model for the future of retail—one where technology fosters deeper trust and ensures every customer can confidently walk away in the perfect pair of shoes.
