PROBLEM TO BE SOLVED: To solve the problem of difficulty in finding most suitable size by all means when selecting a shoe among ready-made shoes, since human feet have various shapes in a strict sense and right and left feet of a person are not completely similar to each other in shape. SOLUTION: The shoe includes, as the outer shell, an upper and a sole that are flexible but hardly stretchable. A low-hardness rubber-like elastic body which has an ordinary temperature hardness in Asker C hardness measurement of 17-30 is applied or stuck to the whole interior surface. Alternatively, a low-hardness rubber-like elastic body viscosity of which is reduced at 60-70°C or higher to be freely deformable, and then a natural state shape of which is fixed at lower temperatures is applied or stuck to the whole interior surface.
