Recommendations for Side Step/Platform...

Does anyone have a recommendation for side steps that are not tubes....I know there is a name for them, but can't think of it right now...I'd like to get tubes because of the "Look" factor, but I have a handicap daughter and I would hate for her foot to slide off and get trapped between the tube and the side of the truck. Looking for something more enclosed that is more functional but still looks nice. Aluminum or SS prefered.

I'd appreciate some guidance on this...thanks!

 

I am looking at N-fab nerf bars. They have a 3" drop for the steps. A little spendy compared to typical bars, but if you plan on having the truck for a while, they may be a viable option.
