The invention relates to an insole and provides an intelligent correction insole which is simple in structure, and can effectively detect walking posture features of a wearer and provide effective correction aiding for the wearer. The intelligent correction insole comprises a detection insole layer, an air cushion insole layer and an inflation control machine. The air cushion insole layer is separably arranged on the detection insole layer. The detection insole layer is provided with a pressure sensing module, an infrared sensing module, a control module and a USB connection module. The infrared sensing module is used for detecting the height of an arch of one foot, the pressure sensing module and the infrared sensing module are connected with the data end of the control module, the control module is connected with the USB connection module, and the control module can achieve data interaction with the inflation control machine through the USB connection module. Air cushion protrusions are arranged at the positions, corresponding to the pressure sensing module and the infrared sensing module, of the air cushion insole layer, inflation openings are formed in the air cushion insole layer, and the inflation control machine can inflate the air cushion insole layer through the inflation openings.
