Large Klipsch’s usually have those shiny little metal things forced into the corners of the risers like my Heresy IVs and my Cornwall IVs. Really all you need to worry about is whether the speakers are level and towed in properly. You can use a bubble level like the one for your turntable or the one you have in your toolbox.
I made footers by visiting our local Economy Hardware and purchasing some PVC end caps used to terminate runs of plumbing along with some sticky felt pads to prevent damage to the footers and disguised the PVC’s tan color with some strips of black electrical tape all in an effort to compensate for the thickness of the carpet and the overhang on the hardwood floor when the speakers are positioned properly. See the result below. As far as fancy footers go probably a waste of money unless you’re just doing it for the bling. If you can't make out the bubble level image you can expand it with your thumb and forefinger if you're using an LCD display.
