Abstract: The invention relates to a method for influencing the pronation behaviour of a shoe (1), especially of a sports shoe, in which a) at least on parameter (?, d?/dt) is measured (2) which is relevant for the behaviour of pronation, b) the measured parameter (?, d?/dt) is led to a control unit (3), c) the control unit (3) outputs an actuation signal (S) which is influencing the behaviour of pronation to an actuator (4) and d) the actuator (4) changes a property of the shoe (1) which property is relevant for the behaviour of pronation. To better influence the behaviour of pronation the invention is characterized in that the processing of data of a parameter (?, d?/dt) measured according to step a) takes place from a reference point of time (tK), wherein the reference point of time is determined from the touch down of the shoe (1) on the ground.
