I wish there was a mat(s) that covered the carpeted slope to the back seats. Grass from soccer shoes gets all over the carpet as the kids enter the car.

Thanks, but should have clarified - the carpeted slope of the back seat footwells.
I consideried sticky-back carpet protector (the plastic on a roll), but worried about how extreeme temperature fluctuations would affect it.
