The present invention relates to the sole structure of the shoe, and in particular, can be implemented to have a climbing effect to climb uphill slope regardless of the type of shoes, while replacing the insole can be used as ordinary shoes, but also excellent shock absorption ability joints and ankles It is to provide a sole structure of the shoe to enable the protection of.

Shoes are worn to protect the user's feet from the external impact caused by walking and driving, the appearance design and structure is different depending on the purpose and place of use.

For example, when you go out lightly, you wear sandals, sneakers and shoes for everyday life, and special sports shoes for the sport. Recently, functional shoes specialized for special functions are spreading. .

In particular, in recent years, the interest of the general public has increased, and functional shoes have been developed that can show the exercise effect even when driving and walking by wearing shoes. However, most functional shoes have a unique appearance by emphasizing only their functions. There was a discomfort to be ignored.

And even if the user takes such an unusual appearance for the exercise effect, there is a problem that the wearing of the shoe is no longer possible in daily life after seeing sufficient exercise effect or the unusual appearance.

The object of the present invention can be implemented to maintain the ordinary design of the shoe, regardless of the type of shoes can be worn without minding the eyes of others, but to achieve the climbing effect to climb the uphill slope by only wearing it, It is to provide a shoe structure that can be used as a normal shoe that does not have a mountain climbing effect, and at the same time has a particularly excellent shock absorbing ability to protect joints and ankles.

In the sole structure of the shoe according to the present invention for achieving the above object, the upper portion of the shoe is combined with the upper portion of the rear portion is higher than the forefoot portion has a rising upward slope, the upper shape is made along the foot shape, the rear portion is relative The forefoot part includes a main sole that is higher than the rear foot part while having a front ascending slope to be located at the lowest point.

And, it is made of a uniform thickness along the foot shape, and further comprises an insole which is placed on top of the main sole, the shape of the upper portion is made along a portion of the foot shape, the shape of the lower portion of the corresponding upper portion of the main sole It is made along the top of the main sole, the thickness is thicker toward the rear foot, characterized in that it further comprises a secondary insole to make the rear foot higher than the forefoot.

Alternatively, the upper portion is formed along the foot, and the lower portion is formed along the upper form of the main sole, but the thickness becomes thicker from the forefoot to the rear of the foot so that the rear is more than the forefoot. Characterized in that it further comprises an insole made to be high.

In this case, an uneven portion is formed in the lower portion of the rear foot of the auxiliary insole or the insole to prevent slippage in the main sole.

The insole and the auxiliary insole are characterized in that the high elastic material (deletion).

When described in detail with reference to the accompanying drawings, a preferred embodiment of the sole structure of the shoe according to the present invention made as follows.

1 is a perspective view showing the appearance of the shoe is applied to the sole structure of the present invention, Figure 2 is an exploded perspective view of the sole brush is covered on the main sole in the sole structure of the present invention, Figure 3 is a work on the main sole in the sole structure of the present invention 4 is an exploded perspective view in which an auxiliary insole is placed between a main sole and an insole in a brush structure of the present invention, and FIG. 5 is a state in which an auxiliary insole is placed between a main sole and an insole in the brush structure of the present invention. 6 is an exploded perspective view of another insole covered by the main sole in the sole structure of the present invention, FIG. 7 is a longitudinal cross-sectional view of another insole covered by the main sole in the sole structure of the present invention, and FIG. 9 is an exploded perspective view of the sandals to which the structure is applied.

The overall structure of the shoe is largely divided into a sole that touches the sole of the wearer while constructing the sole of the shoe, and an upper that functions to cover the wearer's foot and protects the foot while preventing the shoe from peeling off.

Looking at the material, the upper is made of natural or synthetic leather for soft and durable comfort, while the sole is made of rubber, polyurethane or other cushioned material to absorb the impact of walking.

Such shoes can be implemented in a variety of sandals, sneakers, shoes, hiking shoes, etc. according to the structure and materials of the upper and the sole, and the sole structure according to the present invention can be applied to the shoes of all such aspects, In particular, a description will be given taking the conventional sports shoes as an example.

The shoe A structure of the present embodiment shown in FIG. 1 is also made by the edge of the main sole 10 adhered to the upper 30, and the upper portion of the main sole 10 with a uniform thickness as shown in FIGS. It further includes an insole 20 which is covered to be replaceable in accordance with the shape to further absorb the shock of the wearer.

The upper portion of the main sole 10 is formed along the foot shape (足 形), as if the wearer's foot is made in the engraved shape to provide a comfortable while touching the wearer's foot when actually wearing.

Referring to FIG. 3, which shows a longitudinal cross-section in more detail, between the forefoot portion 14 and the forefoot portion 12 is not flat, but rather rises to support the arch 13 of the sole, and the forefoot portion ( 11) and the forefoot 15 are raised to finish to form a generally smooth W shape.

In addition, the main sole 10 according to the present invention has a front ascending structure, in particular, the height of the upper portion is substantially increased toward the forefoot portion 12, so that the portion corresponding to the foot portion 14 is located at the relatively lowest position. There is a characteristic to having.

Therefore, when wearing the shoe according to the sole structure of the present invention, the shape of the upper sole to cover the foot while providing comfort and walking and running while maintaining the forefoot portion 12 is raised than the rear portion 14 .

As such, the state in which the forefoot portion 12 is raised from the forefoot portion 14 is the same as that of the foot when hiking with normal shoes, so that the center of gravity of the wearer is biased behind the body and the body of the wearer is instinctively. Since trying to straighten, wearing a shoe according to the present invention to maintain such a state walking and driving on a flat general road in everyday life brings a climbing effect, such as walking the slope with the same slope.

In addition, in the main sole 10 of the present invention, as the forefoot portion 12 increases in relative angle as compared with the rear foot portion 14, the effect of climbing a higher mountain is brought about. In the design and manufacture of the main sole 10, it is possible to take a variety of angles in consideration of the use and movement effects.

Meanwhile, the shoe according to the present invention can function as a normal shoe by inserting the auxiliary auxiliary sole 21 added between the main sole and the insole as shown in FIGS. 3 and 4.

That is, the auxiliary insole 21, which is applied to the sole structure of the present invention and lies between the main sole 10 and the insole 20, has an upper part along a part of the foot type, and a lower part is in the main shape. The foot is formed along the corresponding top of the sole and placed on the corresponding top of the main sole 10, but the thickness thereof becomes thicker toward the rear foot 14 so as to be placed on top of the main sole 10. It is characterized in that the higher than the forefoot portion (12).

Therefore, when the auxiliary insole 21 is laid on the main sole 10, the shoe A according to the present invention becomes the same as the normal shoes of the forefoot portion 12 lower than the rear portion 14, the climbing effect When it is not necessary simply by inserting the auxiliary insole 21 in addition to the main sole 10 and the upper insole 20 will be able to continue to wear shoes in flattening.

However, in such embodiments, it is not necessary to use the insole 20 over the main sole 10 and / or the auxiliary insole 21, and the insole 20 may be omitted according to the embodiment. It is possible.

In some embodiments, the insole 20 'as shown in FIGS. 6 and 7 may be added as the auxiliary insole of the above example is coupled to the insole.

That is, the insole 20 'is the same as the first insole 20 in that the upper shape is formed along the foot shape and the lower shape is formed along the upper shape of the main sole 10, but the thickness thereof is In the state where it is thicker from the forefoot portion 12 to the rear foot portion 14 and placed on the upper portion of the main sole 10, the rear portion 14 is higher than the forefoot portion 12 so as to spread the entire upper portion of the main sole 10. By doing so, the same effect as in the embodiment in which the previous auxiliary insole 21 is inserted between the main sole 10 and the insole 20 is achieved.

And the insole (20, 20 ') according to the present invention is made of a high elastic material such as polyurethane, for example, the thick portion of the rear portion 14 is excellent shock absorption to protect the joints and ankles and fatigue due to running and walking Of course, while the foot 14 is sufficiently indented by the cushion to support the arch 13 of the sole relatively, the foot pressure effect is generated, and at the same time the friction of the sole arch 13 It will prevent the slip itself.

On the other hand, the lower portion of the insole 20 and the lower portion of the auxiliary insole 20 'is formed with an unevenness 22 to prevent slipping in the main sole 10, in particular, a thick enough rear portion It is also preferable to form the unevenness 22 only at 14.

The main sole 10 may be made of a single material and structure itself, or may be made of a multi-stage structure such as an outer sole and a midsole. The structure of the main sole 10 is well known to those skilled in the art, and thus, do.

The longitudinal cross-section of the main sole 10 has a structure that is fully synergistic and gives a unique effect according to the present invention, whereas the forefoot 30 is raised for finishing similarly to the forefoot 11 and the forefoot 15. As shown in Fig. 1, the edge portion 16 is thicker than the forefoot portion 12 side from the side as shown in FIG. 1 so that the appearance of the finished shoe A is not different from that of a normal shoe. It's a good idea to keep the brush structure out of the way so people won't get your attention.

On the other hand, the sole structure of the present invention is not due to the external peculiarities of the sole, but due to the internal structure is not exposed to the outside at all, it can be applied to any kind of shoes, such as sneakers, shoes, in particular Figure 8 And the sole structure of the sandals shown in Figure 9 can be seen that the back is low because the sole structure of the upper part is completely exposed, but wearing the actual sandals do not feel the appearance unusual while the functional part is the same as described above will be.

According to the sole structure of the shoe of the present invention made as described above, regardless of the type of shoes, the climbing effect of climbing the slope uphill only by wearing it can be worn without minding the eyes of others by maintaining the ordinary design of the shoe On the other hand, the replacement of the insole can be used as a normal shoe that does not have a mountain climbing effect, and at the same time has a unique effect that can protect the joints and ankles, especially excellent shock absorption.
