[Confused]

Re the above posts, I was also thinking very much the same thing ..... How do these things work, what is the interaction with the shelving etc. Anyway, does anyone know what the science is here, that is, exactly what do these footers do, what do they need to work correctly, what is one trying to achieve by using such supports. I am not trying to be cynical here, enough people are claiming that there are big SQ improvements to make me think there is something in this, but how exactly do they work?
