1 - the biggest benefit actually comes from decoupling the subwoofer from the floor not by the absorption of the bass.
2 - So instead of using the standard tiny feet or no feet at all, using feet like these actually stabilize the unit more as well.
You're right in that a risers main purpose is to decouple the sub from the floor reducing the muddiness of the bass and making it more pronounced. But they aren't made to to absorb the bass at all, only the vibration that causes everything to rattle and shake. If they absorbed the bass they would be kind of counter productive.
The small footprint is part of what isolates the vibrations. They work the same as floor spikes for towers, the less contact area the higher the pressure on the feet meaning less vibration.
Like someone already pointed out bass builds up most in the corners, corner traps and acoustic panels are your best bet. Something like these. Obviously this is a more expensive option, there's always DIY.
