Subaruguru,
Mr. Kohan is correct provided one looks at a cone footers function without regards to the substrate material that the cone's tip interfaces with.It's not actually the cone itself which provides the benefits and so-called "directionality" but rather the cone footer's filtering effects makes damping easier for the substrate by raising their frequency, combined with the high pressures applied to the substrate,which, *when optimised* will promote localised deformations of the substrate material beneath the cone's tip and subsequent energy losses via their conversion to heat.
best,
Ken
