As described above, contact pressure and stimulation response can be measured by a foot scanning device (P53). And an evaluation index for the separation area of the measured foot can be generated (P54). When the measurement of the measured foot is completed, the evaluation index of the measured foot is compared with the standard index to calculate a comparison value (P55). And based on the contrast value, foot or foot-related disease diagnosis data can be generated (P56). Based on the diagnostic data, it can be assessed whether foot correction is necessary (P57). If calibration is not required (NO), the 3D insole can be modeled against the diagnostic data. In contrast, if correction is necessary (YES), a walking posture model can be created (P58), and an insole with correction pressure applied based on the walking posture module can be created (P59). When the virtual insole is created in this way (P59), virtual wearing is performed based on the virtual insole and the corrected walking posture can be searched (P60). Artificial intelligence algorithms can be applied in this process. Afterwards, a 3D insole can be created based on the virtual shoe. Artificial intelligence algorithms may be applied in the process of exploring the suitability of virtual insoles through virtual ignition, but are not limited to this.
