The inner sole is positioned on the upper surface of the shoe bottom, undergoes by itself elastic deformation when one walks and provides the shoes with a cushioning property. The upper and lower layers of the slip are molded from a synthetic resin so as to define a void layer between them. Supports are disposed between the upper and lower layer and support the upper layer. The supports are integrally molded with either the upper layer or the lower layer. The inner sole having supports molded integrally with the upper or lower inner layer can be mass-produced most economically by blow-molding of synthetic resin. |
