However, with the conventional technology described above, it is necessary to improve all the burden factors on the foot, such as maintaining the arch shape of the arch, preventing excessive inversion of the ribs, and absorbing the load and impact during walking and running. Not reached.
The present invention has been made in view of such conventional circumstances, and the object of the present invention is to maintain the arch shape of the arch and prevent excessive inversion of the ribs, and to load on walking and running. It is an object of the present invention to provide a novel insole for shoes capable of effectively absorbing a shock and a shoe equipped with the insole.

  In order to achieve the above object, the present inventors have measured the shape of the foot bones of a wide range of ages from infants to adults. As a result of intensive research, we found that foot deformity has started, and it is normal to correct foot bones during soft childhood to childhood (between 3 and 12 years old). It was found that it is extremely useful for bone formation, and the present invention has been completed.

That is, the insole for shoes according to the present invention has a toe part, a stepping part, an arch part, and a bottom part of a part extending over the arch part and the heel part of the insole body made of a cushion material in which the heel part is integrally connected, A sole plate made of a hard material is joined and a shock absorbing pad is joined to the bottom surface of the heel portion of the sole plate, and the sole plate is an arch portion and a heel portion excluding a toe portion and a stepping portion of the insole body. The arch part and the heel part corresponding to each of the arches are integrally connected and formed in an arch shape along the arch shape of the sole, and the arch part and the heel part are integrally raised from the side edges of the arch part and the heel part. the inner protective surface, the heel protective surface, with an outer protective surface, the inner protective surface is formed higher than the outer protective surface, the shock absorbing pad, a heel portion bottom surface of the sole plate by a high resilience of the cushion material Characterized in that it is formed in a horseshoe shape along the edge.
