I spent the extra for the ones that retract up some when you take your feet off. They are very nice. Good quality. Install was not bad, Take your time. Be prepared that you may have to re-do some of it to get it "Dialed in" to your comfort. It is not bad tho. Instructions could be better. Multiple adjustments make these nice. You will need to get some Blue Loc-Tite for some of the hardware. It is not included. They look sharp too. I have pics on my profile page.
