There is an amplified stomp board called, I think, the Porch Board. Google that and you'll probably find them for sale at Elderly and such. You also might find several threads about the Porch Board and also some home made versions over on the IGS forum.
[Edit - Looks like Slack already did the search for you.]
As fate would have it I am currently trying to come up with a low wooden box to stomp on that will sound good thru a mic, i.e. I don't want the sound of 'effects', just the natural sound, whatever it is, the closer to a porch the better. Fortunately I work in a cabinet shop and have lots of wood, planed to whatever thickness I want, to experiment with.
All for now.
