Carpet floor mat protection

[Jungle Rot]

I have the standard carpet factory floor mats for my 09 automatic sedan. I noticed that the mat does not extend high enough to protect the area where your left foot usually rests while driving. I'm assuming that this area will begin to wear out. In my Honda CRV, this area is hard plactic so there is no wear on the carpet.

Does this area wear out? How can I protect it. Maybe changing to all season floor mats, but will these cover the area in question.
