The present invention relates to an insole to be inserted into a shoe. More specifically, the present invention relates to an insole inserted into a shoe so as to precisely scan a sole of a customer through a 3D scanner to design an outline of the insole, The pressure distribution is analyzed by measuring the distribution, and the pressure density is adjusted by adjusting the filling density of the air layer formed inside the sole so that the pressure can be uniformly distributed on the sole using the topology optimization based on the analyzed pressure distribution deviation The present invention relates to a human-sensitive pressure-based dispersion insole and a method of manufacturing the same. The present invention relates to a human-sensitive pressure-based dispersion insole and a method of manufacturing the same.

Generally, the sole of the body has arches that support the body weight and other loads, and absorb shocks applied to the sole while maintaining the balance of the body. All three arches (medulla, medulla, and medulla) are found on the soles and are known to mature at approximately 9 to 12 years of age. When the load is applied, it becomes flat, and when the load is removed, it returns to its original position.

Since the skeletons forming the cervical spine are connected by ligaments and muscles, unstable gait leads to changes such as making the cervical spine too high or low, and the change of the cervical spine causes human pain, And it leads to the change of the footbath and it is vicious circle. This causes foot diseases, such as flat feet, braces, and plantar fasciitis, and harms the health of the feet. In addition, it causes arthritis and disc diseases in the legs and spinal muscles, thereby deteriorating the health of the legs and vertebrae.

Accordingly, in recent years, as the desire for health has become stronger, there has been an increasing demand for a functional shoe that comforts the foot to maintain a healthy foot. However, since functional shoes are relatively expensive due to their specificity, they are inevitably used in a very limited manner. In addition, since the cost burden is incurred for a certain period of time as a consumer product, interest in functional insole have.

However, conventionally developed functional insole is manufactured not in a customized insole adapted to the shape of the sole of a customer but in a uniformly standardized form in most factories. In addition, even if the customized insole is manufactured, it is manufactured in accordance with the shape of the footwear of the customer, or the footwear is manufactured so as to be adjustable in height according to the shape of the footwear, and simply manufactured to support the footwear, In fact.
