Nike says you might be wearing the wrong size shoe, so it created an AR tool to help

Nike Fit will utilize smartphone cameras and augmented reality to scan users' feet and measure the full shape of both feet. If you don't know which size shoe to buy when ordering sneakers online, the world's largest shoe company is rolling out a possible solution. Nike is introducing a feature to its app that lets you scan your feet using your smartphone camera to determine what size shoe will be the perfect fit. Aptly titled, Nike Fit, the AR tool seeks to replace the steel measurement device that you find under the seats at your local shoe store. It's a timely development as more consumers shift their shopping habits online.
