Car Mats

Need to confess a small issue I have, I absolutely find it frustrating entering a car that has fluffy clean floor mats after I've been on a somewhat dirty walk or something, I just don't know how to position my feet and dirty shoes. I love it when the car I'm entering has all weather floor mats, means I don't have to worry about messing up the owners car. I know it's a little strange, I still don't even feel comfortable when the owner of the car says it's fine, I'm ever aware of the position my feet are in and I just can't get comfortable, just one of my many nuances.
