Prefer good quality coiled mats with raised edges, over trapo/rubber patterned mats.

Why? Cuz my heel feels much more comfortable and secure sitting hinged (between each pedals) on a comfy coiled mats over hard mats. No smell, and provides some sound deadening.

Trapo/rubber mats looks dirty over time and makes the interior looks like a contractors cars. If you got GF, trapo/rubber mats are difficult for them to drive in short heels due to the patterns wedging the heels.
