I can tell you for a fact that is significantly more important how the shoe reacts to inversion and eversion forces at the heel than the amount of impact cushioning the shoe has. At heel strike, the rate at which your heel everts(turns out) has a large impact on the stability of your midfoot. Those shoes do not appear to be very sound, biomechanically, though I have not seen them in person. I guess I could get the Adidas rep to detail me on them. They are just trying to differentiate themselves with the microprocessor shoe, they will sell a lot of them, because runners are as obsessive as anyone you will meet.
