In the second case, why spikes? Why not just the rubber pad?

You want to minimize the area of contact with the pad. Plenty of more
efficient ways to do that than spikes, mind you, but spikes are usually
what people have handy.

I've thought that the minimal contact area was important but the
smaller you go the higher the pressure so do things remain the
same ?
