Shocked removed spikes, used blue tack, what other non spike footer

My floor standing speakers, monitor stands always came with spikes so I used them always, it's the way they were designed at least I thought. I know everyone can't do this because of there floor type, mine is hardwood over concrete slab. Bass, more natural tone( I'm a tone junkie)  gives the music a nice rhythm, may just be flavor of month but I'm really enjoying it. Highs maybe little rolled off, I just did it yesterday, maybe not as hifi, but no lose of information. Have other people experienced this.Can someone with my floor type suggest a nice reasonable priced non spiked footer, these are floorstander filled with shot so pretty heavy,maybe 70- 80 lb. thanks

@audiopoint, great stuff, keep it  coming. Fascinating subject.

Who keeps tripping their post off the  vertical polarity edge of a shear wave? I have my most favorite guess. Tom 
Meanwhile, back on the subject of footers and other sundry items, here's another vote for Gaia products:

All the best,
Oh, great! The other dude who doesn’t think there’s any such thing as isolation. Buckle your seat belts, gentle readers, this ride could get bumpy. Still mumbling about shear waves, eh, Tom? That never gets old. 🙄 OK, you may go ahead with Damage Control. I need a good laugh.
