A device for avoiding excessive loads on the human foot when walking comprises a shoe insole having at least one force sensor for generating a measurement signal indicating loads and/or partial loads on the foot； an analyzing unit electrically connected to the at least one force sensor for analyzing the measurement signal of the at least one force sensor； an electric power source to provide electric power to the analyzing unit； and a feedback control signal generator which generates a feedback control signal on the basis of the analysis of the analyzing unit for monitoring loads and/or partial loads on the foot, e.g., by means of an actuator, wherein the sensitive components are disposed in a housing to protect them, in particular from water and/or pressure loads. Furthermore, a method for operating the device is provided.
