A sensor device has an insole, a sensor body abutting the insole, pressure sensors operably mounted on the sensor body for generating a pressure data signal, and an accelerometer mounted on the insole for generating a movement data signal indicating the measuring movement of the insole. A transmitter is used for transmitting the pressure data signal and the movement data signal to a reporting device having a receiver for receiving the pressure data signal and the movement data signal. The reporting device further has a processor and a computer-readable medium for storing the pressure data signal and the movement data signal.
