After reading every post on the web I decided to try Husky X-act contour floor liners. I had the factory Ford mats(80.00) and they slide around and mine also warped where your heal is. I put the Husky liners in and they are awesome,they do not slide around they fit tight. Made from a softer compound than the weather techs. They are the only mats that I found that are advertised to work on carpet and vinyl. Highly recommend these.JP68

 

I have those too and really like them. I wish they made them for the back seat in a super cab.
