技術分野
[0001]
本発明はシューズに関し、特に運動用のシューズに関する。
背景技術
[0002]
従来、例えば中距離又は長距離のランニングのような競技に用いられるシューズにおいて、走り易さや安定性等の機能性を向上させるために様々な技術が提案されている。このようなシューズの機能性の内の一つに加速性がある。例えば特許文献1には、靴底の反発機能を高めることでシューズの加速性を向上させることが記載されている。
先行技術文献
特許文献
[0003]
特許文献1:特許4704429号公報
発明の概要
発明が解決しようとする課題
[0004]
本発明は、特許文献1とは全く異なる技術的手段により、加速性に優れる構造のシューズを提供することを目的とする。
課題を解決するための手段
[0005]
上記課題を解決するために、本発明は、
接地面及び当該接地面とは反対側を向いた接足面とを有する軟質材製のソールと、
当該ソールの接足面側に結合されたアッパーとを備え、
前記接足面と前記接地面とがなす角度が8〜16度となるように、着用者のMP関節に対応する位置における前記ソールの厚みと踵中心に対応する位置における前記ソールの厚みが異なっている。
[0006]
このような構成によれば、シューズの接地面が地面に接触したときに着用者の足裏を前傾させられる。これにより、着用者が地面を蹴る力を効率的に
部分同士を連結するように配置された軟質材66が設けられている。軟質材66は、例えばフォーム、又はGEL等の弾性が高い材料で形成されている。軟質材66は、上下の二カ所で中空部64の内面を構成するミッドソール62の表面に固定されている。このように中空部64を定める構造の一部を軟質材66で形成することにより、上記の変形例による効果に加えて、衝撃吸収性能を高められる。
[0038]
図10は、実施例によるシューズの実験結果を示すグラフである。図10は、8人の被験者が実施例によるシューズと、従来のシューズ(比較例)をそれぞれ着用して、350m走を行ったときの走破時間の変化率を示す。実施例によるシューズは、傾斜角度が12度であった。比較例によるシューズは、傾斜角度が3度であった。図9の縦軸には、比較例によるシューズを着用した場合の走破時間に対する、実施例によるシューズを着用した場合の走破時間の変化率を示す。同図に示すように大部分の着用者の走破時間が短縮されていることが分かる。一部の着用者は、測度比が10%近く大きくなった。
[0039]
本発明は上述した実施形態に限られるものではなく、各構成は本発明の趣旨を逸脱しない範囲で適宜変更可能である。また、上述した実施形態を一般化すると以下の態様が得られる。
[0040]
〔態様1〕
接地面及び当該接地面とは反対側を向いた接足面とを有する軟質材製のソールと、
当該ソールの接足面側に結合されたアッパーとを備え、

[0041]
〔態様2〕
前記ソールは中足部において上方向に凹んだアーチ部を有する、態様1に記載のシューズ。
