Just a few points to ponder.

1. Most of the foam ear plugs you buy in sporting goods stores/departments only eliminate ~32db
2. Most ambient noises that could cause you to have to react in the name of safety are going to be much louder than 32db
3. Custom made foam plugs only eliminate around 40db (I personally prefer to spend a whole lot less money on the others especially in the event of losing one now and then.)
4. Wind noise will cause hearing loss and as someone else pointed out that never comes back
5. Wind noise also causes fatigue

Pick your personal level of protection or not.
