Abstract

A walking-assisted air-jet insole includes an insole base. A plurality of pressed-air outlet units that can generate airflow based on stepping pressure are provided on the insole base; the pressed-air outlet unit includes a cavity for retaining air. An upper part of the insole base is provided with an upper air hole that communicates with the cavity, and a lower part of the insole base is provided with an air sac part that is elastically deformed and restored based on the stepping pressure. A volume of the cavity can be changed based on the elastic deformation and restoration of the air sac part. A lower end of the air sac part is provided with a convex column that moves up and down based on the stepping pressure. The cavity includes an upper cavity portion and a lower cavity portion from top to bottom.
