I agree with you, up to a point (if you will pardon my pun).
The floor or shelf will have vibrational nodes, just like any other object. If you can position the tiptoes supporting the item you want to isolate such that they are in contact with a point on the surface of the floor or shelf that does not move when the floor or shelf is excited by some other external force, then you can achieve the diodic effect claimed for tiptoe-like feet. The energy can drain into the floor or shelf, and very little energy wants to flow back up into the tiptoe.

You can find the nodes, sometimes, with a stethoscope.

To the OP, gravity has NOTHING to do with this.

"gravity has NOTHING to do with this. " Ya sure about that Lew? Please explain how this would work without gravity. I must say that the nothing in capitals gives this point of view gravitas, if you excuse the pun. Tweekie666

  Perhaps my statement that gravity has nothing to do with "this" was an oversimplification. Gravity has everything to do with weight, of course. But I think the OP was asking whether the potential analogy of a tiptoe to a diode had to do with an effect of gravity on energy flow, as in the notion that gravity is somehow pulling energy down and preventing energy from moving up into the supported device. I may have misunderstood the OP's question about gravity, but my answer to that latter hypothesis is "no". Is that better?
