OconeeOrange:
My sub is on the deck - so stains are no problem.  Never saw a stain in my running shoes though.

Sorbathane actually comes in many densities and the weight levels can be checked on line.   
I actually bought this lighter density to get better results, but higher density can be bought.
This one is rated for 500 pounds per inch.
To go beyond that, I bought two sheets.  I put one 4X4 under the middle of the concrete paver block.  I cut one more into one inch squares for the corners.  That seems to be spread out more than enough to support the sub.  Spikes might concentrate the weight, but the concrete paver spreads it out.  At any rate - it is working quite well. 

I don't think sorbathane compresses quickly.  As a runner, you just put it under your heel and it takes a big hit with each foot strike.  That is thousands of strikes over a ten mile run.  I never wore one out.
