The invention belongs to the technical field of insole detection devices, and particularly disclosed an intelligent insole capable of detecting pes supinatus and pes pronatus different in size. The insole includes an insole body, a processor terminal and an adjusting mechanism; the adjusting mechanism includes a vertical rod, a toe cross rod, a foot arch cross rod, a heel cross rod, a toe connecting block, a foot arch connecting block and a heel connecting block. By adopting the insole, pressure data of six areas of a planta pedis can be detected, judgement of pes supinatus and pes pronatus can be achieved according to the pressure data, and meanwhile, by means of rotary connection between the vertical rod and each cross rod, the size of the insole is changed, one pair of the insoles can be designed for different sizes, and therefore the insole can be used by multiple people to detect different foot sizes, and is convenient to operate, capable of saving the cost and suitable for detection in hospitals and the like.
