DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a shoe sole body 1 and a heel member 10 separated from each other according to an embodiment of the present invention. The main body 1 of the shoe sole occupies a large part of the sole of the shoe, and has an upper support member 2 having an upper surface for supporting the sole of the wearer, and a bottom surface attached below the support member 2 to directly reach the ground. The thin ground contact member 4 is formed, and the lower half of the rear half of the support member 2 is removed, and the arch 6 is recessed upward in the removed region.
When both ends 6A and 6B of the arch 6 reach the ground, the bottom surface 5 of the ground contact member 4 is inclined obliquely upward from the ground. Here, since the support member 2 has some elasticity, a material that bends when the wearer walks or runs is selected. The material for the ground contact member 4 is selected to be more flexible than the support member 2 and to absorb or absorb the impact with the ground. And the above-mentioned Japanese Patent Application No. 4-27
As in No. 7078, the upper surface 3 of the support member 2 is inclined at an angle of about 15 degrees with respect to the bottom surface 5 of the ground contact member 4, and the bottom surface 5 of the ground contact member 4 has both ends 6A and 6B of the arch 6 When it reaches the ground completely, it makes a maximum inclination of 25 degrees from the ground, and the front end 6A of the arch 6 is about 40% from the rear end of the main body 1 of the shoe sole when the total length of the main body 1 of the sole is 100%. It is arranged to be in the front position.

On the arch 6 of the support member 2, a so-called dovetail-shaped projection 7 having a narrow upper and lower width is formed in the lateral direction, and the projection 7 is connected to the heel member 10 as described later. It is formed as one element. The heel member 10 has the typical form of a conventional shoe heel. The heel member 10 is made of two kinds of materials similarly to the main body 1 of the shoe sole, and includes, for example, a rigid support body 11 and a shock absorbing pad 12 attached to the lower surface of the support body 11. The upper surface 13 of the heel is formed in a shape corresponding to the curved surface of the arch 6 of the main body 1 of the shoe sole.
The bottom surface 14 of the shoe directly contacts the ground at substantially the same angle as the bottom surface 5 of the shoe bottom body 1.

The upper surface 13 of the heel member 10 is provided with a recessed groove portion 15 as another element of a connecting means for connecting the heel member and the main body of the shoe sole. The groove portion 15 is configured to fit with the above-mentioned protruding portion 7 of the body 1 of the shoe sole so that the body 1 of the shoe sole 1 and the heel member 10 can be easily inserted / removed in the lateral direction in the form of a dovetail. ing. In addition, with respect to such a coupling means, the protrusion 7 and the groove 15
Can be formed by exchanging the above, or by inserting in these directions, that is, the one inserted from the lateral direction to the front from the rear. In addition, the protruding portion 7 and the concave groove portion 1
