<p>The shoe inner sole for a sports shoe, has a front (F) and back part (R) that have different compressibility and rigidity. The back part is more compressible and extensible and the front part is rigid. The two parts are joined by an intermediate part (I) that is extensible. The front part can slide freely on the corresponding internal part of the shoe while the back part is fixed to the sole. The sole can be covered by a uniform layer of non-slip material, that transmits the stresses to the sole.</p> |
