PROBLEM TO BE SOLVED: To provide a method for installing a plantar plate capable of installing a plantar plate which has a shape corresponding to a plantar arch of a human and a convex part in a part corresponding to an apex of a lateral arch of the plantar arch by positioning the plantar plate precisely and easily on a shoe bottom or an insole to be laid on the shoe bottom.SOLUTION: A convex member which has a shape corresponding to a convex part 4b of the plantar plate 4 and has a transcription means at a position corresponding to an apex of the convex part 4b is pasted on a sole of the human so that the position of the transcription means corresponds to a position of the apex of the lateral arch, the sole is positioned at a shoe bottom or the insole 2, and pressurized in a state that the convex member is pasted. Thus, the position of the apex of the lateral arch is transcribed onto the shoe bottom or the insole 2 as a transcription trace 3 by the transcription means, the plantar plate 4 is positioned on the shoe bottom or the insole 2 so that the position of the transcription trace 3 transcribed on the shoe bottom or the insole 2 corresponds to the position of the apex of the convex part 4b of the plantar plate 4, and installed.COPYRIGHT: (C)2008,JPO&INPIT【課題】人間の足底アーチに対応する形状を有し、かつ足底アーチの横アーチの頂点に対応する部分に凸部を有する足底板を、靴底又は靴底に敷くインソールに正確かつ簡単に位置合わせして装着できる足底板の装着方法を提供すること。【解決手段】足底板4の凸部4bと対応する形状を有し、かつ凸部4bの頂点に対応する位置に転写手段を有する凸部材を、前記転写手段の位置が横アーチの頂点の位置と一致するように人間の足底に貼着し、凸部材を貼着した状態で、足底を靴底又はインソール2に位置合わせして押圧することで、前記転写手段によって横アーチの頂点の位置を靴底又はインソール2に転写痕3として転写し、靴底又はインソール2に転写された転写痕3の位置と、足底板4の凸部4bの頂点の位置が一致するように、足底板4を靴底又はインソール2に位置合わせして装着する。【選択図】図3
