Padding can dampen impact from jumping, but it cannot actually reduce the gravitational forces when you are standing. So I am very wary of this concept- instead, if you feel pain stop doing it. Padding stops you from using your feet and moves more of the stabilizing burden elsewhere, which could be bad for some people- although seems to be working fine in your case. Either way one is loosing out on the chance to gradually strengthen the feet in a natural way.
