Hi all, I am wondering if it is recommended to place a thin sheet of foam/rubber between a foil adapter (US track) and the board?

I preordered a Fanatic skywing which I am planning to use with my Slingshot hover glide windsurf foil along with the US track adapter. I noticed the fanatic foil adapters have a thin layer of rubber or foam on them to provide some protection to the board. The slingshot adapters do not have this and am wondering if it is required?

Seems like a sensible thing to do and wouldn't be very hard. Obviously the layer of material would need to be thin enough not to deform under load.

This is the Slingshot adapter with aluminium as the mating surface.
