WeatherTech FloorLiners are laser-measured for specific vehicle makes and models for custom-fit protection. The mats line the vehicle's interior carpet up the front and back sides of the foot well, according to the company.

A patent-pending, high-density, tri-extruded (HDTE) material creates a rigid core for strength while offering surface friction to the carpet, as well as tactile feel to the surface. The FloorLiner surface design includes channels that carry fluids and debris to a lower reservoir with further channeling to help minimize fluid movement while driving. Once fluids become trapped in the reservoir, away from shoes and clothing, they are easily removed from the WeatherTech FloorLiner over the door sill. 

The FloorLiner is designed for vehicles with factory carpet installed when manufactured.  They will not fit vehicles with vinyl floors unless otherwise specified.
