From the looks of it, it doesn’t appear they have high walls. Maybe not a big deal to some but the fact that the floor mats have high walls and that the middle hump in the back is covered has saved me from two potentially big messes recently. I was driving and had those drink holding cartons on the front passenger floor. I did a left turn and all 4 drinks toppled over and spilled. Luckily it was contained in the floor mat and all I had to do was take them out and rinse them with water. Good as new. The tuxmats are my favourite “mod” and investment for my car so far.
