I just installed a set of Fox WeatherBoots (CUSTOM MOLDED ABS FOOTWELL LINERS) to replace the Ford Floor Mats. They look great and fit pretty well also. They were quick to install, but there was a slight gap on the front set around the drive train "hump". All-in-all, I am very satisfied. They are very well made and should last a long time. The design should also prevent any spilled liquid from "pooling" under my feet. Link to there website is below.

Now I am looking at the Wet Okole seat covers - lots of great ideas on this Forum!
