PROBLEM TO BE SOLVED: To provide an internal structure and insole structure of a shoe, which can widely distribute and absorb impact against a heel part and further improve its exercise function for easy walking while alleviating fatigue with a stable shift of centroid, without degrading a shoe strength, a shoe insole rigidity with respect to a torsion near the heel part or the like, a shoe durability, and the like.SOLUTION: In an internal structure and insole structure of a shoe, an urethane part, a plastic part, and an impact absorbing material are stacked in this order from above. In the internal structure and insole structure of the shoe, the impact absorbing material and the heel part of the urethane part are directly joined through a heel part hole of the plastic part, and the urethane part having a unique shape is integrally held by the rigid plastic part. |
