Just put something beneath it. Some people use Nickles, some people might put the speaker on a slab of granite with felt beneath to protect the floor, and then some spikes come with small trays that sit below the spike to keep it from damaging the floor.
Rubber feet are always the worst way to go in my opinion, if you have hardwood floors you should still use the spikes but put something beneath them to protect them.
