Foot Size Measurement
Reference for the foot scan and the size widget. The merchant recipe is Recommend a shoe size. This is not a clothing size, and it is not a button in the Shopify app or the WooCommerce shoes plugin.
Shoppers scan their feet once, then stores can recommend a size for a specific shoe. The public app lives at size.wearfits.com.
The documented result is an advisory modal. An on-shoe fit picture is not part of this integration.
What shoppers do
- Open size.wearfits.com from a product page, a QR code, or a direct link.
- Scan on Android (Chrome WebXR) or iOS (App Clip). iOS also has a web fallback.
- Wait for the result page (length, width/girth, and size labels).
- Optionally return to the shoe they came from.
A scan can be reused: if the device already has a WEARFITS foot profile, the app can skip a new scan.
What stores get
The Size SDK adds a “check my size” action on a shoe product page. The store sends internal shoe dimensions (tryonSizeFit). WEARFITS returns an advisory recommendation (size + fit), not raw foot measurements.
WEARFITS must register your store clientId and origins before go-live.
