Abstract
An inflatable shoe stretcher includes a bag body that is formed by coupling outer peripheries of two bag sheets and that defines an air-filling space therein, an one-way air inflow unit that is mounted between the bag sheets for filling air into the air-filling space, and a heat-sealed unit that is formed by coupling portions of the bag sheets. The heat-sealed unit includes two main heat-sealed subunits for segregating the air-filling space into three air-filling space portions. The bag body is able to be bent alongside the main heat-sealed subunits when the air-filling space portions are filled with air.
