Take out the original carpeted mats and the digital liners should not move.

 

I removed my original carpet mats.

 

You may want to check out a company called exactmats. They are based out of TX and provide a clear mat that is cut exactly to your OEM mats and clip on to prevent sliding. You still have the look of the OEM mat and the protection of an all weather. We have had them in our last two vehicles and just ordered sets for the new E350 and GLK350 today. Front set of four (either car) was $82.50 and the cargo mat was $72.50 all with free shipping.

We traded our 2007 RX 350 on the GLK and when we took the exact mats out for appraisal it looked like the carpet / mats were brand new. Great product and like the fact they are US based aftermarket.

No affiliation with the company, I just like the product.

 

^^^there is only one problem with them, they don't catch water or whatever you might spill on them. Otherwise looks like a good option, def. better looking.

 

We don't get much snow down here but have plenty of rain in the spring / summer and never had a problem. The surface area is more than enough to hold what little water I track in on my shoes. Now snow would be a different story completely and I would need some type of lip / rim to contain the water.
