SUMMARY OF THE INVENTION In order to achieve the above object, the present invention firstly provides footwear such as slippers and sandals.
Forming a side chevron projection on the upper surface of the bottom of the portion where the fingertip hits from the base of the finger. Second, the protruding part forms a portion corresponding to the second joint of the toe on the top of the chevron. Thirdly, the gist of the invention is that a bulging portion having substantially the same height as the protruding portion is formed on the upper surface of the bottom of the portion where the heel of the foot touches.

According to the first aspect of the present invention, since the tip of the toe rests on the projection of the lateral mountain shape from the base of the toe, the finger bends in a downward-shaped "ku" shape, and each time the user walks, Each time a stretching effect is obtained, the back side of the finger is pressed from below, so that an acupressure effect is obtained and blood circulation is improved. Since the projection is grasped by the entire finger, the projection can be kicked rearward by the finger during walking, making it easy to walk.

According to the second aspect of the present invention, in addition to the above-described operation, since the portion corresponding to the second joint of the toe is located at the top of the chevron, the protrusion is formed in a bent shape of the toe. Thank you
The toe fits into the protruding part, and the protruding part can be kicked out satisfactorily.

According to the third aspect of the present invention, in addition to the above-mentioned effects, the heel portion is also bulged, so that the balance between the front and the rear is improved, and walking becomes easier.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of footwear according to the present invention, and FIG. 2 is a perspective view of the same, illustrating a sandal in which a band 2 is attached to a bottom 1 on which the entire sole rests.

The bottom 1 has a mountain-side projection 4 formed on the upper surface of the portion where the fingertip 3b comes in contact with the base 3a of the toe 3 at the tip of the band 2 from the mounting position. The protruding portion 4 is formed with inclined portions 4b and 4c that have the mountain-shaped top portion 4a located at a position corresponding to the second joint of the toe 3 and that face forward and rearward downward.

Further, a bulging portion 5 having substantially the same height as the protruding portion 4 is formed on the upper surface of the bottom portion 1 at the portion where the heel of the foot touches. The height of the bulging portion 5 is, for example, 10 to 18
mm.

Further, the band 2 may be a fixing member, but a member having elasticity is used, and at least the upper surface of the bottom portion 1 is provided with a fine uneven shape or a mesh so that the sole of the foot is hard to slip. Further, a fixing tool such as a magic tape (trade name) may be used for length adjustment.

Next, the usage will be described. While wearing footwear, the instep of the foot is fixed with band 2, and the toe 3 is
The toe 3 protrudes further forward than before, and the toe 3 rests on the protrusion 4. At this time, the base 3a of the toe 3 is located at the lower end of the inclined portion 4b behind the projecting portion 4, the second joint of the toe 3 is located at the top 4a, and the fingertip 3b is located at the forward inclined portion 4c. . Also,
The heel rests on the bulge 5.

In this state, the toes 3 are bent so that the fingertips 3b are directed downward on the protrusions 4, and
Since the joint portion rests on the top 4a and the base 3a bends upward, when the weight of the entire sole is applied, the entire back of the toe 3 is pressed onto the protrusion 4 to obtain acupressure. This results in better peripheral blood flow.

At the same time, the toes 3 are stretched by bending in the shape of a "ku".

The acupressure action and the stretching action are further strengthened by walking, and the base of the toe 3 is further bent. When the operation of kicking out the foot during walking is performed, the toe 3 grips the entire protrusion 4 so as to wrap it around, so that the protrusion 4 can be kicked backward with the toe 3. In particular, since the fingertip 3b corresponds to the inclined portion 4c in front of the protrusion 4, the inclined portion 4c
As a result, a backward pushing force can be obtained, and walking can be favorably performed.

Also, since the heel portion is also lifted by the bulging portion 5, the heel portion is balanced with the toe portion lifted by the protruding portion 4, and the center of gravity moves rearward, making it difficult to stand upright. It does not become difficult to walk because it is turned upside down.

Further, since the band 2 for fixing the instep is provided, the base 3a of the toe 3 can be fixed to the bottom 1 of the footwear with the bunt 2 and the toe 3 can be fixed while walking.
, The toes 3 can be held on the protrusions 4, and the stretching and the acupressure action can be ensured. In this case, if the material of the bottom part 1 is formed of a non-slip material, the anti-slip action is further ensured.

Also, by using an elastic material for the band 2, it is possible to easily turn the sole of the foot when the heel is lifted during walking, and to fit the foot of the footwear when landing. Performance can be improved.

Next, the results of comparison of changes in peripheral blood flow when normal footwear and the footwear of the present invention are worn will be described with reference to the graph of FIG. The subject is an adult male (28 to 48 years old) who is healthy and has no physical impairment such as walking difficulty,
A woman (20 to 53 years old), the experimental period was about 10 days, the first five days were changed to normal footwear at work and worn during working hours, two days after the holiday, and the next five days the present invention And worked as above.

The combination of the two cases was performed four times, and observation measurement was performed. The experiment was conducted by selecting footwear having a size easy to wear.

The blood flow is measured using a simple contact probe (diameter 0.
8 mm, Omega Flow FLO series) 1.5 cm in diameter
Place it on the center of the donut-shaped supporter, with the same size reflector directly above, and stick the whole to the belly of your right toe with special adhesive tape. In this state, the patient was rested in an upright position, and the measurement was performed using a laser-type micro blood flow meter (Omega Flow FLO-1). Measurements were taken immediately before putting on the footwear, at lunch with the footwear on, at 3:00 pm, and when returning home.
Times.

FIG. 3 shows four of each of six healthy subjects.
The average of the measured values obtained in the experiments is summarized, the vertical axis shows the blood flow measured on the ventral side of the right toe, the horizontal axis shows the measurement time, and FIG. FIG. 3B shows the result when the footwear of the present invention is worn, and FIG. 3B shows the result when the same subject wears the normal footwear.

From these results, different results were obtained with respect to the peripheral blood flow depending on the subject, but in any case, in the case of ordinary footwear, a decrease in the blood flow was observed according to the wearing time. On the other hand, when wearing the footwear of the present invention, a decrease in blood flow was not observed in most subjects,
Even when a decrease was observed, the blood flow rate was higher than that of ordinary footwear. Therefore, in the footwear of the present invention, blood flow is hardly reduced, and fatigue is less likely to occur even when the footwear is worn continuously.

In general, fatigue may be caused by physical energy consumption, or may be caused by accumulation of creatinine and lactic acid in a biochemical metabolic function system. On the other hand, one of the factors for preventing recovery from fatigue and preventing fatigue is improvement of peripheral circulation. Therefore, securing blood flow is a means for preventing fatigue from continuing.

[0027]

As described above, the footwear of the present invention can be used without prolonged use of the soles of the soles, so that they do not hurt or get tired, and they can be easily removed when walking. The dashi can be performed satisfactorily, the walking is not difficult, and the stretching effect as well as the acupoint stimulating effect by pressing can be expected.
