an outsole (1) having a predetermined thickness;
a plurality of accommodation grooves (10) which are provided at an anterior portion and a posterior portion of the outsole (1), and respectively include a groove portion (12) having a cylindrical structure of a predetermined depth, of which an upper portion is opened toward a top surface of the outsole (1), and a penetrated portion (16) having an upper end communicating with a center of a bottom surface of the groove portion (12) and a lower end penetrating a bottom surface of the outsole (1);
a support member (20) which is accommodated in the respective accommodation grooves (10), and includes a support portion (22) having a cylindrical shape of a predetermined height and disposed in the groove portion (12), a first guide portion (24) formed at a center of the support portion (22) to have a predetermined depth, an upper portion of the first guide portion (24) being opened, and a second guide portion (26) communicating with a center of a bottom surface of the first guide portion (24), a lower end penetrating a bottom surface of the center of the support portion (22), in which the second guide portion (26) is disposed coaxially with the penetrated portion (16);
a movable member (30) which is disposed in the respective support members (20), and includes a latch portion (32) latched onto a lower portion of the first guide portion (24), and a protruding portion (36) having an upper end engaged to a bottom surface of the latch portion (32), and a lower extended portion penetrating the second guide portion (26) and the penetrated portion (16) in order and exposed through the bottom surface of the outsole (1);
a pressing member (40) which is engaged to the upper portion of the first guide portion (24) to seal the upper portion;
a resilient member (50) which is disposed in the first guide portion (24), of which an upper end comes into contact with a bottom surface of the pressing member (40), and a lower end comes into contact with a top surface of the latch portion (32) of the movable member (30); and
a midsole (2) of a predetermined thickness which is engaged to the top surface of the outsole (1) so that the pressing member (40) comes into integrally contact with an upper portion of the support member (20), wherein:
the groove portion (12) and the penetrated portion (16) of the accommodation groove (10) are formed to be inclined by a predetermined angle θ to a normal line N of the bottom surface of the outsole (1) in a counterclockwise direction; and
an auxiliary support member (60) is interposed between the accommodation groove (10) and the support member (20); a semi-cylindrical seating groove (13) is formed on a front portion of the accommodation groove (10); the auxiliary support member (60) has a lateral wall (62) of a semi-cylindrical structure and a bottom plate (66) of a semi-circular plate structure which is provided at a lower portion of the lateral wall (62); and the auxiliary support member (60) is disposed in the seating groove (13) at a front thinnest portion of the bottom surface of the groove portion (12) relative to the bottom surface of the outsole (1).
