Description of the Related Art Conventionally, a relatively soft material is used in a forefoot portion of a shoe sole where a grip force is required, and fine irregularities and fine grooves such as a herringbone and a honeycomb shape are provided in the shoe sole. Was. And, in the form in which fine irregularities are provided on the forefoot portion of the shoe sole, there is a problem that when a large lateral force is applied to the shoe sole during exercise, a so-called chip is generated in which the end of the shoe sole is chipped. Was. So, conventionally,
The foot sole of the shoe sole is provided with fine irregularities and the like, and the periphery thereof has a shape without irregularities and the like. On the other hand, in a shoe sole where priority is given to preventing a decrease in the shoe sole, a relatively hard material is used for the shoe sole, and further, the above-mentioned fine unevenness is not provided. Therefore, such shoes have a problem that the grip force of the sole is extremely small. Therefore, in a shoe using a relatively hard material for the sole, it is necessary to provide a waveform from the toe to the heel over the entire sole in order to increase the grip force of the sole.

In order to prevent the above-mentioned chip, if the outer periphery of the forefoot portion is not provided with unevenness or the like, the portion without such unevenness or the like is inferior in flexibility, so the flexibility of the entire forefoot portion is also reduced. It will be. In particular, when a hard material is used on the outer periphery of the forefoot portion having no unevenness in order to prevent a decrease in the sole of the shoe, the flexibility is significantly reduced. On the other hand, when a soft material is used in a portion where no unevenness or the like is provided, the flexibility of the entire forefoot portion is not impaired, but there is a remarkable drawback in that the shoe sole is greatly reduced. On the other hand, in order to avoid the above-mentioned problem of a decrease in the sole and the occurrence of chips, in a form in which the entire sole is corrugated without providing fine irregularities or the like, a higher grip force than a sole without a corrugation is provided. It is possible to achieve
There is still a problem that the grip force is low as compared with the form in which fine irregularities are provided. Therefore, there has been a demand for a shoe sole having a high gripping force, avoiding generation of chips, and having a high flexibility as a whole of the shoe sole.

る。[0006] First, the material of the outer edge portion and the grounding portion is not particularly limited, and solid rubber or foamed rubber used for ordinary shoe soles can be used. Rubber is suitable. There is no particular limitation on the hardness of the outer edge portion and the ground contact portion, and the embodiment can be carried out with the same hardness as a normal shoe sole. However, since the outer edge is intended to prevent chips at the ground contact portion and to improve the abrasion resistance of the shoe sole, the outer edge portion is desirably harder than the ground contact portion. Specifically, the outer edge portion has a Shore A hardness of 60. The Shore A hardness is preferably about 50 to 60 because the ground contact portion is a part requiring a high grip force. The outer edge portion is desirably about 10 shore A harder than the ground contact portion. The reason is that if the outer edge portion is softer than the ground portion, it is not possible to prevent the tip of the ground portion from being prevented. If there is no difference of about 10 in A hardness, the grip force is increased at the ground portion and the outer edge has abrasion resistance. This is because the effect of increasing the value cannot be clearly obtained. Specifically, when the hardness of the grounding portion is 50, the hardness of the outer edge portion is preferably about 60, and when the grounding portion is 55, the outer edge portion is preferably about 65. On the other hand, if there is an excessively large difference between the hardness of the outer edge portion and the hardness of the contact portion, the balance will be poor as a shoe sole.

る。[0007] The waveform provided at the outer edge portion may be any waveform provided in the direction from the toe to the heel. This is because the shape of the waveform increases the flexibility of the outer edge portion, and as a result, the flexibility of the entire forefoot portion. In a shoe sole provided with a conventional waveform, such a waveform is provided to enhance gripping force. for that reason,
Such a waveform was provided on the entire shoe sole. However, in the present invention, such a waveform is intended to improve the flexibility of the forefoot. Therefore, as an embodiment of the present invention, a form in which a waveform is provided on the entire shoe sole is possible, but a form in which a waveform is provided only in the forefoot part is possible. In addition, since it is necessary to increase the flexibility in the oblique direction with respect to the length direction of the shoe sole depending on the mode of exercise, in such a case, it is desirable to provide an oblique waveform. Here, there is no particular limitation on the shape of the wave provided on the outer edge portion, as long as the shape can be arranged on the sole of the shoe. However, if the wavelength is too small, the effect of enhancing the flexibility by the waveform cannot be obtained. Also, something too large is not valid. Therefore, it can be said that the wavelength of the waveform provided at the outer edge is preferably in the range of 5 to 15 mm.

般的に成人男性用の発明品では２〜８個が適当である。[0008] The greater the amplitude, the greater the effect of enhancing the flexibility. However, the amplitude cannot be greater than the thickness of the sole. Therefore, the magnitude of the amplitude is determined by the thickness of the sole. If the shoe sole is too thick, the weight is impaired, and the flexibility is also impaired. On the other hand, if the amplitude is too small, the effect of the present invention cannot be obtained. Therefore, since the thickness of the sole is preferably in the range of 4 to 7 mm, the amplitude is preferably in the range of 2 to 5 mm. Here, the wavelength refers to the peak 12 of the outer edge 4 as shown in FIG.
And the distance between the adjacent peak 12 and the wavelength 41 shown in FIG. The amplitude means a difference in height between the peak 12 and the valley 13 of the outer edge 4 as shown in FIG.
2. Also, the wavelength and amplitude do not need to be constant values from the toe to the heel of the shoe, but the form that gradually increases from the toe to the heel, the form that gradually decreases, and the form of the forefoot part The embodiment can be implemented in a form in which the maximum or minimum value is taken near the center. Further, the number of waves is determined by the wavelength and the length of the shoe, and is not particularly limited. In general, 2 to 8 pieces are suitable for the invention for adult men.

のが望ましいといえる。The width of the outer edge portion is not particularly limited as long as it is to prevent chips in the ground portion. However, if the width of the outer edge is too narrow, it is not possible to prevent a chip in the grounding portion, and the strength of the outer edge itself is insufficient. On the other hand, if the width of the outer edge portion is too large, the area of the ground contact portion becomes small, and as a result, the grip force is reduced. Therefore, the width of the outer edge can be set within a range of 3 to 10 mm. An appropriate value is determined for the width of the outer edge portion depending on its hardness and the shape of the waveform of the outer edge portion. Generally, it can be said that the higher the hardness of the outer edge, the narrower the width of the outer edge is.

The shape of the unevenness of the ground contact portion is not particularly limited as long as it is the same as the shape of the unevenness used in the shoe sole of the conventional exercise shoe requiring a high grip force. In particular,
The present invention can be implemented with a herringbone type or an uneven shape such as a honeycomb shape. Further, as the shape of the unevenness, it is possible to implement a mode in which a groove is provided in the ground portion. The shape, width and depth of the irregularities are determined by the use of the invention, and in the case of shoes used in a gymnasium such as a basketball or table tennis, the width of the irregularities is generally small and ranges from 1.0 to 3.0 mm. Is desirable.
On the other hand, in the case of trekking shoes or mountain climbing shoes such as mud or dust that easily hits the shoe sole, the width of the unevenness is generally wide.
A range of 0 to 4.0 mm is desirable.

For example, when the ground contact portion is divided into an inner foot portion and an outer foot portion in the length direction of the shoe, the shape of the groove and the width of the groove are changed between the inner foot portion and the outer foot portion. Further, it is also possible to embed a form in which the ground portion is divided into front and rear portions, and the shape and width of the groove are changed between the front side and the rear side. Specifically, the groove of the outer foot portion of the ground contact portion is inclined by about 20 ° toward the inner foot side with respect to the toe direction, while the groove of the inner foot portion is parallel to the toe direction. Further, as shown in FIG. 4, the ground contact portion 3 is divided into four directions, up, down, left and right, and grooves are formed for each of the front inner foot portion 3a, the front outer foot portion 3b, the rear inner foot portion 3c, and the rear outer foot portion 3d. The embodiment can also be implemented in a form in which the direction is determined. Further, the shape of the groove may be changed only at an arbitrary position, or the shape may be an irregular shape of an arbitrary shape. As shown in FIG. 4, the rear outer leg 3d may have a honeycomb shape instead of a groove. Implementation is possible. Further, it is also possible to adopt a mode in which the groove at the portion corresponding to the thumb ball portion is a honeycomb shape type, and the groove at the other portion is a herringbone type. Further, the grounding portion does not need to be formed with a uniform hardness, and can be embodied in any form in each portion in the grounding portion. Specifically, when the ground contact portion is divided into right and left, the outer foot portion has a Shore A hardness of about 55, and the inner foot portion has a relatively soft Shore A hardness of about 50 in order to increase clipping force. The embodiment can also be implemented in such a form. Further, when the ground contact portion is divided into front and rear portions, the embodiment can be implemented even when the toe side has a Shore A hardness of about 55 and the heel side has a Shore A hardness of about 50.

が可能である。Further, when the irregularities of the grounding portion and the shape of the groove are individually changed in each portion, there is a possibility that a chip may be generated at a portion which is a boundary where the shape of the groove changes. Therefore, it is desirable to form an independent grounding portion for each of the portions having the unevenness and the groove of the same shape, and to provide an outer edge portion around each grounding portion. Specifically, as shown in FIG. 4, the outer edge 4 is arranged around each grounding portion. Also, as shown in FIG. 4, the embodiment can be implemented in a form in which a groove 43 having no waveform is not provided between the outer foot portion and the inner foot portion. And
In this embodiment, an effect of increasing the flexibility in the width direction of the shoe can be obtained. In the practice of the present invention, the form of the heel is not limited, and can be implemented in various forms used for ordinary shoe soles.
