A shoe insole comprising: an insole body ; a calcaneal anterior-part support protrusion that is provided in a region corresponding to a calcaneal anterior part of a foot having a calcaneus whose calcaneal front-side upper end acts as a point of effort (P1), whose calcaneal rear part acts as a fulcrum (P2) and on which a moment around the fulcrum (P2) is exerted, the calcaneal anterior part being directly below the point of effort (P1), and that abuts the calcaneal anterior part in order to maintain an inner longitudinal arch , an outer longitudinal arch , and a transverse arch of the foot; and a toe ball support part that is formed on a back surface of the insole body whereby a gap is generated between a close part of the toe ball support part and an inner sole of a shoe and that supports a thenar and hypothenars of the foot, with the calcaneal anterior-part support protrusion maintaining the inner longitudinal arch , the outer longitudinal arch , and the transverse arch , wherein an anterior edge of the toe ball support part extends on a line connecting from a first proximal phalanx to a fifth proximal phalanx of the foot, and a portion of the anterior edge between the first proximal phalanx and a second proximal phalanx is recessed backward, an insole front part thinner than and softer than the toe ball support part is provided in front of the toe ball support part . an insole body ; a calcaneal anterior-part support protrusion that is provided in a region corresponding to a calcaneal anterior part of a foot having a calcaneus whose calcaneal front-side upper end acts as a point of effort (P1), whose calcaneal rear part acts as a fulcrum (P2) and on which a moment around the fulcrum (P2) is exerted, the calcaneal anterior part being directly below the point of effort (P1), and that abuts the calcaneal anterior part in order to maintain an inner longitudinal arch , an outer longitudinal arch , and a transverse arch of the foot; and that is provided in a region corresponding to a calcaneal anterior part of a foot having a calcaneus whose calcaneal front-side upper end acts as a point of effort (P1), whose calcaneal rear part acts as a fulcrum (P2) and on which a moment around the fulcrum (P2) is exerted, the calcaneal anterior part being directly below the point of effort (P1), and that abuts the calcaneal anterior part in order to maintain an inner longitudinal arch , an outer longitudinal arch , and a transverse arch of the foot; and a toe ball support part that is formed on a back surface of the insole body whereby a gap is generated between a close part of the toe ball support part and an inner sole of a shoe and that supports a thenar and hypothenars of the foot, with the calcaneal anterior-part support protrusion maintaining the inner longitudinal arch , the outer longitudinal arch , and the transverse arch , wherein an anterior edge of the toe ball support part extends on a line connecting from a first proximal phalanx to a fifth proximal phalanx of the foot, and a portion of the anterior edge between the first proximal phalanx and a second proximal phalanx is recessed backward, an insole front part thinner than and softer than the toe ball support part is provided in front of the toe ball support part . <EOS>
