PURPOSE: An outsole capable of pronation and supination is provided to facilitate pronation and supination related to the feet part and ankle joints when walking or running, thereby improving the body's balance and efficiency when walking and running. CONSTITUTION: An outsole capable of pronation and supination has a part dividing an outsole into an upper part and a lower part by a space either on the left or the right side of a foot at the front foot part and the rear foot part of the outsole. When the outsole is pressed, the divided part gets closer, when the outsole is out of being pressed, the divided part gets further, thereby a foot is rotated around a shaft formed in the longitudinal direction of the foot, and the pronation and supination are applied. The outsole is divided into an upper part and a lower part by forming a space on both sides of a width direction of the foot. A hinge shaft is installed in the longitudinal direction of the foot on the middle part of the width direction of the foot on the front and rear foot parts respectively. On the upper and lower parts, an upper part rotating piece which is convex downwards, and a lower part rotating piece which has less curvature than the upper part rotating piece are equipped. A hinge connecting part of the upper and lower part rotating pieces are connected to the hinge shaft to be rotated. |
