Similarly, when the foot pressure distribution of the pedestrian is similar to that of (4) of FIG. 5 as an example, since the foot pressure is concentrated in front of the right foot, a stimulus is generated at the position, ), The stimulation is generated at the corresponding position because the low pressure is concentrated in the back of the right foot. If the distribution of the low pressure is similar to that in (5) of FIG. 5, Therefore, a stimulus is generated at the corresponding position.

As described above, the smart insole for correcting a walking posture according to the present invention is configured to provide stimulation at different positions according to the walking habit of each of the pedestrians by the pressure measuring unit and the stimulation generating unit installed in the insole, In contrast to the prior art, even when the same insole is manufactured without the need to manufacture a dedicated insole for each user, it is possible to apply the invention to different users who have different walking habits, thereby remarkably improving the productivity and profitability of the insole manufacturing have.

In addition, since the smart insole for correction of a walking posture according to the present invention can easily change a position at which a stimulus is provided until a foot low pressure distribution of a pedestrian exhibits a standard foot low pressure distribution using one insole, In contrast to the prior art in which a user-customized insole is manufactured unconditionally by using the analysis after the analysis is completed, there is an advantage that waste of resources that occurs when a low-pressure analysis is wrong or an insole is made improper is prevented.
