PROBLEM TO BE SOLVED: To provide a lower limb correction appliance for concave feet which improves the disturbance of an alignment of a series of lower skeletons caused by an excessive pronation of feet, maintains lower limb biomechanics (an exact alignment of lower limb skeletons), and alleviates an incongruity and a pain resulting from a systemic improper posture caused by the disturbed alignment of the lower skeletons.SOLUTION: This lower limb correction appliance for concave feet includes two main bodies in which attachment spaces are formed. The main bodies comprise: sole parts having foot arch zones which are formed inside； ankle parts connected to the sole parts； foundation parts extending to the ankle parts from the sole parts, and adjoining each other so as to surround the attachment spaces； and elastic auxiliary parts extending upward while passing positions of ankle bones of a human body at the ankle parts toward upwardly inside after downwardly bypassing from the inside of the foot arch parts corresponding to cuneiform bones of a human body, and adjoining each other so as to surround the attachment spaces.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】足の過剰回外による一連の下肢骨格の配列の乱れを改善させると共に、下肢バイオメカニクスを維持させ（正確な下肢骨格の配列）、乱れた下肢骨格の配列によって全身的な姿勢不良からの不快感及び痛みを緩和させる凹足向け下肢矯正装具を提供する。【解決手段】本発明は、内部に着用空間が形成される二つの本体を含み、該各本体は、内側に形成される足弓区を有する足裏部と、該足裏部と接続する足首部と、該足裏部から該足首部に延伸し、前記着用空間を囲繞するように隣接する基礎部と、人体の楔状骨に対応する前記足弓区の内側から下向きに回りこんだ後、上向きに内へ向かって前記足首部における人体の距骨に対応する位置を通過して延伸し、前記着用空間を囲繞するように隣接する弾性補助部と、を備える。【選択図】図１
