I strongly recommend the Rycote "InVision" shock mounts. They are considerably more effective than any other types I've ever seen or used. They also have proper cable clamps, without which no shock mount is effective.
There are models for complete microphones (small or large diameter) and also for capsules on extension cables, such as those by Schoeps and Neumann.
