How to Find Shoes That Fit with Prime AI Shoe Finder
Finding shoes that fit properly and feel comfortable is still one of the biggest frustrations in retail. That’s why so many fashion retailers are now turning to artificial intelligence to help their customers get it right the first time. The result? Fewer returns, higher profits, and a dramatically improved shopping experience.
In this article, we explore the common challenges around shoe sizing and explain how Prime AI’s Shoe Size Finder is helping retailers increase sales and customer satisfaction across both digital and physical retail channels.

Whether online or in-store, buying shoes that fit well remains a major pain point for shoppers. Standard size guides and calculators often miss the mark, leading to high return rates and abandoned baskets.
That’s where AI steps in. Prime AI’s technology takes the guesswork out of sizing, helping shoppers find shoes that fit quickly, confidently, and accurately. It’s the way forward for brands that want to deliver a more personal and seamless experience.
The Challenge: How to Find Shoes that Fit
How Prime AI Helps Shoppers Find the Right Fit
Prime AI is the ideal sizing solution for both online and physical stores. It’s easy to use, fast to integrate, and consistently gets it right for your customers.
Retailers using Prime AI have reported a 16% uplift in conversion rates thanks to the improved confidence it gives shoppers when choosing their size. When customers know their shoes will fit, they’re far more likely to complete the purchase – and come back again.
Fit Tech That Works Across Online and In-Store Retail
Prime AI’s Shoe Size Finder can be used seamlessly online or in physical stores. For online shoppers, it gives peace of mind with every purchase, removing the fear of returns. In-store, it speeds up the process, helping customers find their correct size immediately – and freeing up staff to focus on service.
The in-store experience is as frictionless as possible. Customers simply scan a QR code with their phone to access the tool – no app required. Within seconds, they’ll know their size and whether it’s in stock, all before speaking to a store assistant.
This hybrid approach is increasingly in demand. Research from Sherwen shows that one in three shoppers want to check in-store stock levels from their personal device. And if a customer’s size isn’t available? Prime AI steps in with visually similar alternatives, plus options to request restock alerts via SMS or email, or check stock at other store locations.
Moreover, 63% of Gen Z shoppers (aged 16–24) say they’d be more likely to buy if QR codes were used in-store to help them track items they’re interested in. Prime AI answers that demand directly, while also reducing pressure on store staff through a fully self-service solution.

Everything You Need to Know About Prime AI Shoe Size Finder
Prime AI’s Shoe Size Finder is a powerful self-assist tool designed to work across all retail environments. Here’s how it works and what options are available:
Option 1: Brand-to-Brand Shoe Size Converter
Some shoppers already know their size in a familiar brand. With our brand-to-brand converter, they can use that knowledge to find the equivalent in a new label.
It’s quick and simple, but worth noting that accuracy is limited to under 80%. That’s because even shoes that look identical may be produced in different factories, often varying by over a full shoe size.
For retailers who need better precision, Prime AI offers a more advanced, image-based option.
Option 2: Measure Your Foot with a Phone Camera
For precise results, customers can measure their foot using just a smartphone and an A4 sheet of paper. They snap a photo of their foot next to the paper and follow simple instructions. Prime AI then analyses the foot shape, width, and length, and matches it to your actual in-stock shoe inventory.
It’s fast, easy, and accurate – delivering sizing guidance within seconds.
How It Works: Image-Based Foot Measurement
Our AI engine measures foot length, width, and shape with exceptional accuracy, all from a single photo. It delivers results with under 5mm deviation, meaning your customers are far more likely to get the right fit on the first try.
The benefits of Prime AI Shoe Size Finder speak for themselves. Here’s what you and your customers can expect:
