The heavier the stand, the less it will move, and with many hi–fi and pro–audio speaker stands (including many of the models made by Atacama, for example), it’s possible to fill the hollow support column with a heavy material to add mass and to damp resonances. This could be sand, shot or any other heavy but well–damped material.
If you already have a speaker stand with spikes and your floor is made of wood, then you should consider putting some form of isolation platform between the speaker and the stand, to prevent the cabinet vibrations reaching the stand and, through it, the floor. Avoid flimsy stands that move or rock when you touch them. If the final assembly doesn’t feel completely solid, avoid it.
To sum up, the platforms with a heavy plate of some type on top are the most effective, though you can add mass very easily to any type of support by using floor tiles. Similarly, the more massive and better damped a speaker stand, the less vibrational energy is likely to make it through to the floor and less the stand itself will vibrate. Compared with the cost of speakers, adding suitable stands or platforms is relatively inexpensive, yet it can make a very worthwhile improvement to the overall sound quality!
