I've found some custom floor mats that are a much better fit for the driver's side of the FFH. I've been reading on other threads about people looking for floor mats to replace the short one on the driver's side and I had been looking for a mat that went up under the pedals too.
I got a set of mats from http://qualitycarmats.com/
I had e-mailed the company before buying them and they told me the driver's side mat extended 9 inches more than the OEM mats. I received them yesterday and have attached pictures for anyone who's interested in seeing how they fit. I got the 28 oz Stain Resistant Plush Pile which is thicker than the OEM's. They are a little pricey but worth it to replace the Ford driver's side mat which was worthless in my opinion. You'll see from the pictures, I did get gray for my black Ti interior because the black mats always show the dirt more. I think they look fine and the ambient lighting really shows up much better!
The snap grommets were a perfect fit.
Hope this is helpful for people who are still looking for better mats for their FFH.
