ARFits · AR Shoe Fitting & Sizing
Measure feet to ±2 mm in the browser, recommend the right shoe size, and cut size-related returns.
AR shoe fitting uses a phone camera to scan a shopper's foot and match it to a specific model's size — running directly in the browser, with no app to install. This hub explains how it works, compares it to other sizing methods, and documents the impact on returns and conversion.

What is AR shoe fitting?
AR shoe fitting combines two jobs in one mobile flow: it measures the foot and it recommends a size for a specific shoe. A guided augmented-reality scan captures foot length and ball girth, then a recommendation card suggests the best size for the selected model. A fit heatmap shows where a shoe runs roomy or tight — teal where it fits, coral where it's snug — and the shopper can tap to a half-size up to recompute instantly.
The notable shift is that this now runs entirely in the browser. On iOS the scan launches as an App Clip from the web; on Android it uses WebXR. There is no app-store download, and measurements stay on the shopper's device by default. A secondary benefit is the visual try-on: the same flow can show the shoe on the foot in AR, so shoppers judge both fit and look before buying.

Frequently asked questions
How accurate is browser-based foot scanning?
A guided 12-step scan takes about 30 seconds and measures foot length and ball girth to within ±2 mm of a podiatrist scan — around 99% accuracy. Results depend on following the on-screen guidance and adequate lighting.
Do shoppers need to install an app?
No. The scan runs in the mobile browser: an App Clip from the web on iOS, and WebXR on Android. Measurements stay on the shopper's device by default.
Does it actually reduce returns?
Size-related returns are the largest single return reason in footwear (~40% of returns). Reported deployments see roughly a 20% reduction in size-related returns and about a 30% lift in product-page conversion.
Where can it be deployed?
Browser-based fitting integrates with Shopify and WooCommerce, with REST API access for custom and headless storefronts.
