After Doc Brown and Marty McFly made a spectacular appearance on 'Jimmy Kimmel Live!' last night, Michael J. Fox made an appearance as well! He talked about making the epic film 'Back To The Future', and showed off his self-lacing Nike sneakers! You heard that right! In addition to Mr. Fusion, Pepsi Perfect and previews for 'Jaws 19', power laces are now a reality too!
