Hi mate.
Foam plugs are nice if there isn't anything else available but are not the best for your ears.
A couple of years ago I asked my nose-ear-throat specialist for advice and he suggested I try something more professional (and expensive). The best choice is to contact some outfit specializing in professional protections (sorry but I have no idea how they are called in the US) and ask for proper ear plugs. They usual come in two types: there are the custom-made molded types and silicon-based off the shelf types. The former are more expensive but offer the best noise protection and last quite long before needing replacement, the latter need replacement more often but are much cheaper. I picked the latter and I must say I am
very satisfied with them. Wind noise was really starting to become an issue before I started using them but now I can wear both my Arai and Shoei no problem all day long.
Later I will post you the brand I've been using these two years...
