The user scans his/her foot with a mobile phone. This is technically performed with the help of a depth, ToF or Lidar sensor built in smartphones as well as some fancy AI to spatially detect the foot in 3D. This biometric 3D scan is the crux of spotsize’s uniqueness – a digital twin of a human foot using just a mobile phone. As no other vendor spotsize® allows consumers to playfully obtain a scan of his/her foot with AR features The 3D digital twin is the exact representation of the foot scanned.

With the digital twin now acquired, the system can exactly measure the feet and compare with all available shoe data. The algorithm calculates the best fit by matching the dimensions of the real foot with the thousands of real product data records (from the online shop). To find the right size the digital twin is matched in real time. In just a few seconds and with no need to manually enter any data or wait for any further instructions or email notifications, the user gets his/her size recommendation. All seamlessly integrated in one place – the online shop.
