NEW YORK (AP) - Nike wants to meet your feet.

  

The sneaker seller will launch a foot-scanning tool on its app this summer that will measure and remember the length, width and other dimensions of customers' feet after they point a smartphone camera to their toes. The app will then tell shoppers what size to buy each of its shoes in, which Nike hopes will cut down on costly online returns as it seeks to sell more of its goods through its websites and apps.

  

But Nike will also get a flood of data on the feet of regular people, a potential goldmine for the shoe maker, which says it will use the information to improve the design of its shoes. Nike mainly relies on the feet of star athletes to build its kicks.
