NEW YORK -- Nike Inc. has unveiled its first self-lacing sneaker -- it allows users to make the fit looser or snugger by pressing buttons on the side of the shoe.

The world's largest sportswear brand, based in Beaverton, Oregon, unveiled the sneaker along with a host of other innovations Wednesday at a media event in New York.
