I know the OP made a purchase, but I am happy with the factory boards on my 4Runner. I guess they are wide enough that they protect door dings. I had my 4Runner a year in a tight parking lot, and no dings. They also keep stones from hitting.
When I was buying mine I saw a set of take offs on craigs list. I was going to put those on, because the one I was going to buy did not have any running boards. Turns out thta one sold, and I wound up with one that came with them. I would buy the factory ones again.
