AeroTread running boards combine function and style on every level. Rather than individual step pads, they feature textured treads that run the entire length of the boards. This provides safe, comfortable footing no matter where you step. The treads also have a sleek chevron pattern to increase traction, shed water and add a dynamic look.AeroTread running boards provide a 5" wide stepping surface on each side of the vehicle. They mount tight against the rocker panels, not only providing easier entry and exit but also helping to protect the sides of your crossover SUV from scuffs, nicks and scratches accumulated from road debris and gravel spray.
