At this time, it is preferable that the insole body 10 is made of a soft, resilient and highly flexible foaming material such as EVA (Ethylene Vinyl Acetate, ethylene vinyl acetate).

And, as shown in FIG. 6 , a heel support 13 is further formed so as to be recessed downwardly in the upper surface of the insole body 10 in the form of enclosing each recess 60 , which will be described later. The heel support 13 comes in contact with the sole surface of the heel, which is the heel region of the wearer, thereby dispersing foot pressure to move the center of gravity to the back of the foot and to help absorb shock.

The acupressure projection 20 is

As shown in Figures 1 to 6,

The inner support 11 or the outer support 12 of the insole body 10, or a protrusion structure formed on the lower surface of both, is provided in plurality.

In particular, in the present invention, each of the acupressure protrusions 20 has an arc shape recessed in the opposite outward direction toward the area between the inner support 11 and the outer support 12 in which each acupressure protrusion 20 forms an arc shape. It has a structure that gradually increases in height as it goes in the direction of the depression.

As a result, in the insole body 10, the area between the inner support 11 and the outer support 12 forms a flat surface, and the inner support 11 and the outer support 12 are the inner arch and the outer arch of the sole. It is formed to be curved as it slopes upward to fit.

In other words, when the insole body 10 is used as shown in FIG. 4 , in a state in which the insole body 10 is seated on the upper surface of the outsole (sole) 1, the flat lower end of each acupressure protrusion 20 is the The air pocket 30 that can stay in the air inside each of the acupressure projections 20 while coming into contact with the flat upper surface of the outsole 1 is formed.

Therefore, when the wearer walks, when the outsole 1 touches the ground, the sole of the wearer presses each acupressure protrusion 20, and at this time, the air in the air pocket 30 formed in each acupressure protrusion 20 escapes. As it comes out, it is supplied to the sole of the wearer's foot, and on the contrary, the air is introduced into the air pocket 30 while the acupressure protrusion 20 that was pressed when the outsole 1 is spaced apart from the ground is restored by the restoring force. At this time, the inlet air may be air supplied to the sole of the wearer's foot, or may be external air introduced through an upper (skin) that is a breathable material and wraps the back of the foot.

Through this air circulation structure, the inside of the shoe can be ventilated, preventing or worsening diseases such as athlete's foot or eczema on the wearer's feet, and it can also help remove odors such as foot odor. there is.

In the insole body 10, a plurality of grooves are provided so as to be recessed upwardly on the lower surface of the area in contact with the heel of the sole.

At this time, the recess 60, which is a groove structure, can serve as a cushion when the wearer walks, and in particular, when implemented as a vertical through-hole structure instead of a groove, a second air distribution path 70 to be described later is provided. It can also serve as a passage for air circulation through the

The second air distribution path 70 is

As shown in Figure 6,

It has a long groove structure to connect one or both of the recesses 60 and the first air passage 50 .

At this time, like the first air distribution path 50 , the second air distribution path 70 is non-contact with the outsole 1 even though the lower surface of the insole body 10 is in close contact with the upper surface of the outsole 1 . Since it is an area, it can serve as an air passage, so that an air flow between the recess 60 and the first air passage 50 is possible.

Therefore, the first and second air passages 50 and 70 and the recess 60 help air circulation between the lower surface and the upper surface of the insole body 10, so that a little more of the area forming the sole of the foot It can be of great help in circulating air over a large area.
