Difficult! As they should be. I love the fact that they are rubber and not plastic. In our cold climate, I don't want anything that can break or tear in the cold. Will order more. Also: take them out and air them out for a few days before storing them in the car or elsewhere. Rubber initially smells quite strongly of petroleum, but disappears after airing.
