Just a thought...maybe you could put a couple of strips of that stuff you put on stairs/ladders/etc. to prevent your foot from slipping off. You know, it's like coarse sandpaper on one side and 3M adhesive on the other. Sold at any store like Wal-Mart, K-Mart, and auto parts stores. It's usually black so it'll match the running board.
