A test device for monitoring a predetermined pressure load on a patient's foot as exerted by the body weight of the patient during walking has a pressure sensor which is designed as a circular, ring-shaped, curved washer having a snap portion in the form of a conically shaped elevation that can be snapped-over from a rest position into an active monitoring position when a predetermined pressure load is sensed. This the snapping action is accompanied by an audible signal as well as by a sensitive sensing signal acting bodily against the heel of the patient's foot under which the test device is placed.
