I'm a motorcyclist since forever, as well as a professional woodworker. I do ear protection. My 2 cents:
I have never found disposable plugs that either 1) are comfortable or 2) stay fully inserted, so I have custom ones made by an audiologist. If you want to go the foam route (and I know some people that love them) buy one or two of a bunch of different kinds, and see what works best for you. You can usually find a selection at motorcycle shops, or of course a safety supply company - even Grainger's.
