Questions retailers ask
Do shoppers need to download an app?
No. Shoe Size Finder opens directly in the shopper’s internet browser and asks for just one picture of their foot.
What does a shopper need?
Their phone camera and a sheet of A4 or US Letter paper. They place their foot next to the paper and take one photo.
How accurate is it?
The error margin is under 5mm, equivalent to half a shoe size, when measuring foot length from a single picture. It also identifies foot girth.
Which platforms do you support?
Any eCommerce platform, including Shopify, Magento, PrestaShop, Salesforce, Sylius, WooCommerce and headless eCommerce.
How long does it take to go live?
About one week, with minimal effort and zero data entry from your team.
Does it work in physical stores?
Yes. Shoppers check their size and availability and locate the nearest store with the product. In store, it cuts the time staff spend fetching sizes at peak hours.
