The invention belongs to the technical field of health insoles and particularly relates to a foot pressure monitoring insole and a monitoring system thereof. The foot pressure monitoring insole comprises an insole body made of high polymer materials. A pressure sensing device, a data processing device and a data transmission device are arranged in the insole body. The pressure sensing device comprises a pressure sensing element, a circuit amplifier and a data collector. The output end of the pressure sensing element is electrically connected with the input end of the circuit amplifier, the output end of the circuit amplifier is electrically connected with the input end of the data collector, the output end of the data collector is electrically connected with the input end of the data processing device, and the output end of the data processing device is connected with the data transmission device. The foot pressure monitoring insole is based on the biomechanical principle, adopts the Internet of things and the cloud computing technology, and provides scientific basis for early discovery and correcting treatment of hidden health hazards through static collection, dynamic collection and intelligent analysis of foot pressure, detection of abnormal conditions of foot pressure and combination of other health information.
