I don't know if suspensions are necessarily designed to reduce the impact of footfall. The Linn simply sound better--lively and better bass--when the suspension is correctly tuned and the table is placed on an appropriate support surface.
I have experienced all sorts of tables having problems with footfall so I don't know if certain types of suspensions are particularly vulnerable. As a rough guess, I would say that light tables with suspensions, like the Linn and some JA Michell tables seem a bit more vulnerable to footfall. I suspect that a much heavier suspended table, like my Basis Debut, is less prone to problems with foot traffic.
