Customized guidance using AI based on X-ray & foot pressure data. It is easy to optimize for all users through many shapes and hardness adjustments. Using AI, customized insoles can be customized and evaluated in non-face-to-face, and more precise pressure data can be collected and calculated over time. The silicon hardness (Shore D) can be adjusted according to the shape of the foot (arch shape, height, pressure distribution, etc.) to optimize it for any purpose. Because it is manufactured in a prefabricated manner, it is economical and hygienic because it is easy to replace for performance and correction every year.
