It is true that the elastic can be stretched tight on large shoes. The elastic itself and the bottom of the foam pieces are stronger than the back of the piece. It helps to over-stretch the elastic with all the fingers of both hands when you put the marker on, so that all the stress is applied to the elastic, not the foam. This will keep the elastic flat against the foam and the shoe, spreading the pressure. The opposite of that is to roll the elastic onto the foot, this will pull on the foam and twist the elastic into a thread, putting all the pressure on one point of the foam, making it more likely to break. The foot markers are covered by the warranty, I am sending you a private message.
