An adaptive insole system is provided. When a mobile terminal executes an application in a detection mode, the mobile terminal determines a user's foot shape based on an archive database and a plurality of pressure signals from a smart insole and then displays a foot shape message for providing the user with an assessment report of his foot type. In addition, when the mobile terminal executes the application in a walking mode, a control signal is outputted by the mobile terminal according to the archive database and the plurality of pressure signals from the smart insole, so that at least one inflatable area of the smart insole is inflated or deflated for allowing the user's feet to be properly assisted and protected during walking through a physical mechanics principle.一種自適性鞋墊系統,其可藉由移動終端執行應用程式於檢測模式時,依據檔案資料庫與來自智慧鞋墊的多個壓力信號判斷使用者的足型,並顯示足型訊息,用以提供使用者其足型的評估報告。此外,可藉由移動終端執行應用程式於走路模式時,依據檔案資料庫與來自智慧鞋墊的多個壓力信號輸出控制信號,以使智慧鞋墊的至少一充氣區進行充氣或洩氣,用以透過物理力學原理讓使用者的雙腳於走路時能得到適當的協助與保護。
