Herbies Pucks floor spike protectors...

I use them with my Vandy Treo’s. I use them to protect my wood floors.
I can’t say that they either help or hinder, as I would not put spike marks in my floor.
They also help with moving and adjusting the speaker as they glide easily.
FWIW,
I’d be worried if those spikes could put a chip or make a crack in travertine.

I didn't know Vandersteen made spike shoes.

A quick Google shows they should probably work as good as my Herbie's gliders, though some may disagree.
Some of this stuff can get a bit anal.
