I've tried the vacuum cleaner belts and the "O" rings and they tend to 
bounce 'way too much.  Go to the local shoe store and purchase a heel replacement 
for a pair of dress shoes and cut the stoppers from this.  It's still quiet
but it won't rebound as much as the softer materials which will cut down on 
the "popping" noises and such.
Good luck.
