Jeff,

Welcome to the family.

Treating the rubber is easy to do and certainly won't hurt anything so why not.

On the other hand, I don't think it will do any good either. The very nature of rubber will keep any topical coatings or treatments from permeating into the rubber. If they were exposed to UV then there would be some merit.

It is far more important to start with a product that will last. Everyone here swears by MecaTech boots (me too - so far - but then I've only had them on for a few weeks). Time will tell.

The other important thing is to keep an eye on them. If they ever crack or split, replace them IMMEDIATELY.

That's my .02 & others may have different opinions.
