What happens if you pour ketchup on your Nike Mags? It depends. Have they been Crep Protected? If yes, then it’s almost as if you can go back in time before the would-be stain ever happened by simply washing them off. If you didn’t protect your sneakers with Crep water and stain resistant spray, then you are going to need a time machine to get them clean again. To see Crep Protect in action, watch the video below. Don’t worry, no Mags were harmed in the filming of this commercial.
