Looking for ideas here. My wife has a pair of Giro Espada shoes with carbon soles, couple of years old. On one shoe, the carbon portion of the toe is nearly worn through from landing when unclipping. It looks like the normal toe pad there probably got knocked off at some point. The carbon is squishy, again, just at the very tip of the shoe. I want to try and protect this area before it gets any worse. Couple of ideas I have seen are to either use a fiberglass repair kit, or to coat and build up over the area with a two-part epoxy or some kind.

Any other thoughts?
