LiquidTempus has it right ;
No you want your pads to absorb the impact. If you only have a soft pad, then you can end up compressing the soft material and bottoming out on the board.
With the D3O in the middle, when you have an impact your soft upper layer will compress and the D3O will begin to resist and spread the impact over a larger area in the soft under layer.
Then end result is you get more energy absorbed by the D3O pad than you would with a regular soft pad.
I read this also somewhere else ;
As described footpad consists from 5 layers and D3O material is just one of them - the middle layer inside pad. Whole pad from both top and bottom sides is soft. Therefore D3O works as middle shock absorbing layer and other layers ensure softness even at hard impacts.
I hope to try the pads in a week or two, from a local shop.
