The shoe roll includes a revolving shell, which is fixed to two rotatably mounted terminating elements arranged at the ends and can be loaded in the direction of the mating roll via a press shoe matched to the outside of the mating roll. The shell includes a radially inner base layer and an adjacent, radially outer functional layer.
