The present invention relates to a dual midsole for biasing the center of gravity medially toward the sole of a foot, comprising: an inner midsole formed from a material tenderer and softer than that of an outer midsole; a front stepped layer formed lower than the upper surface of the adjacent other part of the inner midsole at a part of the upper outer side of a front surface of the inner midsole and/or a part of a rear surface thereof; a plurality of front insertion holes formed on the front stepped layer by vertically penetrating the inner midsole; and the outer midsole formed from a material having repulsive elasticity greater than that of the inner midsole, and formed by covering all of the upper part of the front stepped layer, the inner sides of the front insertion holes, and lateral sides and a bottom side of the inner midsole. When walking in shoes, the front inner part of the foot is lowered down well due to the tenderer property of the inner midsole and the greater repulsive elasticity of the outer midsole, thereby allowing feet deviated with age to turn inward such that a proper gait posture can be induced. |
