PROBLEM TO BE SOLVED: To solve the problem that the shape of a reinforcing member of a conventional shoe insert is changed because of a load of the sole of the foot and no flapping motion can be performed stably because the side of foot is hard to be fixed and the foot is hard to be fixed inside a shoe.SOLUTION: A support member 1 supports the sole of the foot including the arch of the foot by a flat first bottom surface 2 and a curved second bottom surface 3 and prevents the lateral slippage of the foot inside a shoe by its side face 4. Owing to this structure, the skeletal structure of the foot is fixed at an appropriate position inside the shoe. When a load is applied to the sole of the foot, stability is improved by the first bottom surface 2, thereby improving flapping motion efficiency and preventing turnover.COPYRIGHT: (C)2013,JPO&INPIT【課題】従来の靴中敷の補強部材は、足裏の荷重により変形し、また、足の側面が固定され難いため、靴中にて足が固定され難く、安定した「あおり運動」が行われ難いという問題があった。【解決手段】本発明の支持部材1は、平坦面な第1の底面2と、曲面は第2の底面3とにより土踏まず領域を含む足裏を支持し、その側面4により履物中の足の横方向のずれを防止する。この構造により、履物内の足の骨格構造は適した位置に固定され、足裏に荷重が掛かる際には第1の底面2により安定性が向上するため、「あおり運動」の効率が向上し、転倒防止の効果が得られる。【選択図】図1
