Standmount speakers - alternatives to spikes?

I'm drawing a blank on the name but there is a spike that has floor protector built in. Not attached but it moves with the spike if you pick it up. They advertise in Sterophile...
Oh here, I think this is them

I hated having spikes on my speakes on a wood floor, major production to move them.

These work better than pennies. I sell these but tried the pennies myself a month of so ago, the spikes made a hole almost all the way through and would have gone through eventually.

Your spikes probably use a standard thread such as 1/4x20. If so, I recommend standard threaded furniture feet which can be found at Lowes. Or, while at Lowes, you could get some hex bolts and affix rubber bumpers/pads to the bottoms.

Thanks for all the answers so far. :)

I might not have been very clear. I'm not trying to protect my floor here (pennies are enough for that) but just to explore solutions that could improve sound, like the Vibrapods mentionned above.

Keep them coming!

Better results will be had if you treat the equipment that resides in the rack first and keep the rack coupled to the floor using the spikes. Just make sure that the rack's spikes have the weight equally distribed thus avoiding any wobbling etc. Also, if you can position your stand as to have the feet as close to the floor joist as possible, the better.
