【発明の属する技術分野】
本発明は、足の運びに無理がなくて歩行がし易く、接地面からの突上げ等に対する足裏刺激を緩和することが要求される一般的な靴、サンダル、障害者用履物等の履物底に関する。
【０００２】
【従来の技術】
一般に履物底の多くは、一体成形または接着した踵片を含む、天然皮革、合成皮革、ウレタンゴム等からなる接地底に、レザーボード、ポリプロピレンをバインダーとする不織布、硬質ウレタンゴム等からなる中底を接着積層した構成となっている。
【０００３】
このような構成の履物底を使用している履物は、履物底が僅かに衝撃吸収性を有するものの、全体としては硬質であるために、履いた場合の足裏が受ける触感は硬く、また歩行運足時の履物底の変形態様と、体重移動時に作用する、足の爪先部分、指の付け根部、前踏部、土踏まず部、踵部に対する力に順応した足の運動態様との不一致となり、これが円滑且つ安定的な歩行運足による体重移動の阻害や疼痛、歩行疲労の増大の要因となっている。
【０００４】
特に、円滑且つ安定的な歩行運足による体重移動の阻害は、平衡感覚のとりにくい怪我後遺症のある人を含む障害者用の履物の底構造として不適当であり、その改良が望まれている。
【０００５】
【発明が解決しようとする課題】
本発明は、歩行運足による体重移動時の足の爪先部片、指の付け根部、前踏部片に作用する力に順応する足の運動態様に近似した状態に無理なく変形して順応するともに、硬度差のある足裏前踏部との接触を優しくし、接地面からの突上げ等に対して緩和することにより、疼痛や歩行疲労を大幅に軽減することができる履物底の提供を課題とする。
【０００６】
