[Technical field to which the invention belongs]

The present invention relates to healthy footwear that can naturally contribute to health by wearing it.

【0002】

[Conventional technology]

As footwear that can contribute to health by wearing it, for example, O-leg correction footwear has been considered. This O-leg correction footwear had a shape in which the inner part of the footwear base was lower than the outer part of the footwear base. FIG. 11 is a perspective view of the footwear, and FIG. 12 is a cross-sectional view showing the FF cross section of FIG. In this footwear, it seems that the O-leg has been repaired because the knees are attached when the footwear is worn, but when it is not worn, it returns to the original state. Therefore, this type of footwear needs to be used for a long period of time. However, because the inside of this footwear is low, others can tell at a glance that it is an O-leg correction footwear, and because the inside is low, some people feel uncomfortable wearing it. For this reason, even if I first wore it, I often stopped wearing it over time, and it was not a footwear that I could use for a long time.

[Problems to be Solved by the Invention]

Against the background as described above, the footwear does not feel uncomfortable even when worn, and has the same fashionable appearance as normal footwear, that is, footwear that can be used habitually for a long time. There has been a demand for healthy footwear that can correct such problems.

[Means for solving problems]

In the footwear base that receives the foot, the above problem is solved by forming the inner part of the footwear base that the inner part of the sole touches softly with respect to the outer part of the footwear base that the outer part of the sole touches.

[Example]

FIG. 1 is a perspective view showing healthy footwear according to the first embodiment of the present invention. In the figure, 1 is a footwear base, and 2 is a belt that is passed from a part of the outside of the footwear base to a part of the inside of the footwear base to fix the foot to the footwear base. FIG. 2 is a cross-sectional view showing an AA cross section of the perspective view of FIG. In the figure, 1a and 1b are the footwear materials constituting the footwear base 1, and the material 1a is a softer material than the material 1b. These materials 1a and 1b are generally wedge-shaped when viewed in cross section, and these are bonded with an adhesive or the like. Therefore, the footwear base has almost the same height on the outside and the inside in the thickness direction, and has the same appearance as general footwear. However, the hard material 1b is used thickly on the outside of the footwear base, and the soft material 1a is used thickly on the inside of the footwear base, and the inside is generally softer than the outside.

FIG. 3 is a diagram showing Example 2 in the present invention, and FIGS. 1 and 2 are the same as those in Example 1. 3 is a slit-shaped gap provided inside the sandal body. FIG. 4 is a cross-sectional view showing the BB cross section of FIG. The slit-shaped gap is generally deeper and wider toward the inside, and in the direction in which the weight is applied, the softness increases toward the inside of the footwear substrate. Since the footwear has such a structure, the thickness of the footwear base is almost the same on the outside and the inside, which is the same as the appearance of general footwear.

【0007】

FIG. 5 is a diagram showing Example 3 in the present invention, and FIGS. 1 and 2 are the same as those in Example 1. 3 is also a slit-shaped gap provided in the footwear substrate as in the second embodiment, but the slit-shaped gap continues to the outside. FIG. 6 is a cross-sectional view of the CC cross section of FIG. The slit-shaped gap is generally deeper and wider toward the inside, and becomes softer toward the inside in the direction in which the weight is applied. Since the footwear has such a structure, the thickness of the footwear base is almost the same on the outside and the inside, which is the same as the appearance of general footwear.

【0008】

FIG. 7 is a diagram showing Example 4 according to the present invention, and FIGS. 1 and 2 are the same as those in Example 1. 4 is a horizontal hole-shaped gap provided inside the sandal body. FIG. 8 is a cross-sectional view showing the DD cross section of FIG. The inner side surface of the lateral hole-shaped gap is deep and wide, and is shallower and narrower toward the center, and in the direction in which weight is applied, the softness increases toward the inner side of the footwear substrate. Since the footwear has such a structure, the thickness of the footwear base is almost the same on the outside and the inside, which is the same as the appearance of general footwear.

【0009】

FIG. 9 is a diagram showing Example 5 according to the present invention, and FIGS. 1 and 2 are the same as those in Example 1. 4 is a horizontal hole-shaped gap provided inside the sandal body. Reference numeral 5 denotes a ventilation hole provided on the upper surface of the footwear substrate. Here, the configuration of the horizontal hole-shaped gap is the same as that of the fourth embodiment, but the horizontal hole-shaped gap has a plurality of ventilation holes penetrating to the upper surface of the footwear substrate. FIG. 10 is a cross-sectional view showing the EE cross section of FIG. Since the footwear base has such a configuration, the softness increases toward the inner side of the footwear base in the direction in which the weight is applied. In addition, the thickness of the footwear base is almost the same on the outside and inside, which is the same as the appearance of general footwear.

[Effect of the invention]

In Example 1 according to the present invention, the inside of the footwear base is softer than the outside as a whole. Therefore, if a person with O legs wears the footwear, the inside of the foot of the person sinks, so that the knee naturally becomes a leg. You can move to the center of the footwear and exert the same O-leg correction effect as conventional footwear with a lowered inside. In addition, conventional footwear with a low inside is not comfortable to wear because the action of moving the knee to the center of the leg always works even after the O-leg is corrected. However, in this embodiment, the inner part of the soft footwear base receives the inner part of the foot moderately, so that the comfort is remarkably good. In addition, since there is no difference in thickness between the outside and the inside of the footwear base, it is visually indistinguishable from ordinary footwear, so that it can be worn without worrying about the eyes. In addition, if this footwear is worn, the sole of the foot will have a part that receives a large amount of weight and a part that receives a small amount of weight, which also has the effect of improving the overall posture.

【0011】

In the footwear having a structure in which a gap on the slit is provided inside the footwear base according to the second embodiment, the footwear base can be made of the same material in addition to the effect of the first embodiment, so that the footwear can be easily manufactured. It also has the effect of being a massage on the inside of the sole. In the footwear having a structure in which a slit-shaped gap is provided on the entire surface of the footwear substrate according to the third embodiment, in addition to the effects of the first and second embodiments, there is also a massage effect on the outer sole of the foot. That is, the effect of massaging the entire surface of the sole can be obtained. Further, since a gap through which air passes is continuously formed between the foot and the footwear, there is an effect that the foot is prevented from getting stuffy.

【0012】

In the footwear having a structure in which a horizontal hole-shaped gap is provided inside the footwear substrate according to the fourth embodiment, in addition to the effect of the first embodiment, the tip of the convex portion forming the slit-shaped gap shown in the second and third embodiments. Since the portions (upper end portions) are connected to each other, the movement of the upper surface portion of the footwear substrate in the front-rear direction is suppressed, so that it can play a role of preventing the back-and-forth movement of the back surface of the foot when a person wears it. In addition, footwear also has the effect of being less likely to lose its shape and extending its life. Further, since there is no unevenness on the upper surface of the footwear substrate that the back surface of the foot touches as in the second and third embodiments, the appearance is improved. In the footwear provided with a horizontal hole-shaped gap having a ventilation hole leading to the upper surface of the footwear substrate according to the fifth embodiment, in addition to the effect of the first embodiment, the effect of preventing the back surface of the foot from moving back and forth and the life of the footwear shown in the fourth embodiment. In addition to the effect of lengthening the footwear and the effect of eliminating the unevenness on the upper surface of the substrate and improving the appearance, the massage effect on the back surface of the foot shown in Examples 2 and 3 can also be exhibited. In addition, since it has ventilation holes, it also has the effect of preventing the feet from getting stuffy.
