Description

The present invention relates to shoes that improve the health of the wearer, and in particular to shoes that can improve the contact with the ground through the shoes by applying pressure to specific points while wearing the shoes.

When walking in shoes, the distribution of pressure load when the foot touches the ground changes depending on the shape of the wearer's foot. For example, it is well known that if the wearer has flat feet, pressure load is placed on areas where it should not be, making the wearer more likely to get tired.

For this reason, many efforts have been made to correct the position of the pressure load to where it should be. For example, Patent Document 1 discloses a foot correction device that can be inserted into the insole of a shoe or the shoe itself, has a protrusion that can press the ball of the big toe and the ball of the little toe, and has a step between the heel side and the toe side due to the difference in thickness.

JP 2020-058555 A

In Patent Document 1, by pressing the balls of the big toe and little toe from bottom to top, it is possible to relieve tension in the flexor hallucis longus, flexor digitorum longus, tibialis posterior, peroneus, soleus, gastrocnemius, plantar muscles, etc., thereby expanding the range of motion of the ankle joint, preventing hyperextension of the plantar fascia and knee joint, preventing floating toes, and improving the arch of the sole of the foot. However, the arch that can be improved by the step is the so-called vertical arch, and does not contribute to the formation of the so-called transverse arch shape of the toes. Therefore, there was a problem in that it was not possible to prevent hallux valgus and cold sensitivity due to the collapse of the transverse arch.

The present invention was made in consideration of the above circumstances, and aims to provide shoes that not only reduce fatigue but also prevent bunions and poor circulation by maintaining the so-called transverse arch in the correct shape.

In order to achieve the above-mentioned object, the shoe of the present invention is characterized in that it comprises a pressure-applying member that applies pressure from the outside to the inside to the first metatarsal bone and the fifth metatarsal bone of the user when the shoe is worn by a user, and has a gap portion on the outside of the user's big toe and little toe that allows the ground contact positions of the big toe and little toe to move lower than the ground contact positions of the other toes .

In the present invention, the shoe is provided with a pressure applying member that applies pressure from the outside to the inside to the first metatarsal bone and the fifth metatarsal bone of the user when the user wears the shoe, and has a gap on the outside of the big toe and the little toe that allows the big toe and the little toe to move so that their grounding positions are lower than those of the other toes , so that the grounding positions of the big toe and the little toe are lower than those of the other toes, forming a natural transverse arch shape. By forming a transverse arch shape, blood flow in the foot becomes smooth, hallux valgus can be prevented, cold sensitivity is improved, metabolism is promoted, and a diet effect can be expected. In addition, the user can walk using the entire sole of the foot from heel to toe, and swelling is improved by the active work of the calf muscles, and a beauty effect on the leg line can be expected.

In addition, it is preferable that the pressure applying member of the shoe according to the present invention is belt-shaped and positioned so that it can tighten the first metatarsal bone and the fifth metatarsal bone of the user from the outside to the inside when the shoe is worn by the user.

In the present invention, the pressure applying member is band-shaped and is positioned so that it can tighten the first metatarsal bone and the fifth metatarsal bone of the user from the outside to the inside when the user is wearing the shoes. As a result, the big toe and little toe spread outward using the principle of leverage described below, so that the ground contact positions of the big toe and little toe are lower than the ground contact positions of the other toes, and the position of the toes when viewed from the front can be made to have a natural transverse arch shape.

In addition, it is preferable that the pressure applying member of the shoe according to the present invention has a width equal to or less than the length of the first metatarsal bone and the fifth metatarsal bone of the user.

In the present invention, the pressure applying member has a width equal to or less than the length of the first and fifth metatarsals of the user, so that the big toe and little toe spread outward using the principle of leverage described below, so that the ground contact positions of the big toe and little toe are lower than the ground contact positions of the other toes, allowing the position of the toes when viewed from the front to be in a natural transverse arch shape.

In this invention, the big toe and little toe land lower than the other toes, and the position of the toes when viewed from the front can be made to have a natural transverse arch shape. The transverse arch shape improves blood flow to the foot, preventing bunions and improving sensitivity to cold, promoting metabolism and helping with weight loss. It also allows the wearer to walk using the entire sole of the foot from heel to toe, and the active working of the calf muscles improves swelling and is expected to have a cosmetic effect on the lines of the legs.

FIG.

The following is a detailed explanation of a shoe according to an embodiment of the present invention, based on the drawings. The following embodiment does not limit the invention described in the claims, and it goes without saying that not all of the combinations of the characteristics described in the embodiment are essential to the solution.

Furthermore, the present invention can be implemented in many different forms, and should not be interpreted as being limited to the contents of the embodiments. The same elements are given the same symbols throughout the embodiments.

According to an embodiment of the present invention, the big toe and little toe are placed lower than the other toes, and the position of the toes when viewed from the front can be made to have a natural transverse arch shape. The transverse arch shape improves blood flow to the foot, preventing bunions and improving sensitivity to cold, promoting metabolism and helping with weight loss. It also allows the wearer to walk using the entire sole of the foot from heel to toe, stimulating the calf muscles to improve swelling and provide a cosmetic effect on the lines of the legs.

Figure 1 is a perspective view showing the outline of the configuration of a shoe according to an embodiment of the present invention. As shown in Figure 1, the shoe 100 is equipped with pressure applying members 10 on both sides that apply pressure inward to the foot. Specifically, a ribbon portion 20 is attached to the pressure applying member 10, and by tightening the ribbon portion 20 while the user is wearing the shoe 100, pressure is applied from the outside to the inside of the user's foot.

Figure 2 is a two-sided view showing the state before the ribbon portion 20 of the shoe 100 according to the embodiment of the present invention is attached. Figure 2(a) is a side view showing the state before the ribbon portion 20 of the shoe 100 according to the present embodiment is attached, and Figure 2(b) is a plan view showing the state before the ribbon portion 20 of the shoe 100 according to the present embodiment is attached.

As shown in FIG. 2, the shoe 100 according to this embodiment has a band-shaped pressure applying member 10 on the side. The upper part of the pressure applying member 10 has an attachment hole 11 for attaching a ribbon part 20. When in use, the ribbon part 20 is passed through the attachment hole 11 and tightened, so that the pressure applying member 10 is pressed against the side of the shoe 100, applying pressure to the user's foot.

What is important here is the position and width of the pressure applying member 10. This is because it is important that the shoe 100 according to this embodiment applies pressure from the outside to the inside to the first metatarsal bone and the fifth metatarsal bone of the user when the user is wearing the shoe.

In the example of FIG. 2, the attachment position of the band-shaped pressure applying member 10 and the width of the pressure applying member 10 are determined so that the band-shaped pressure applying member 10 fits within the position of the metatarsal bones when the user is wearing the shoe. This is why the width is relatively narrow.

Of course, the pressure applying member 10 is not limited to being a band-shaped member. For example, it may be formed of multiple string-shaped members so that it fits within the position of the metatarsals when the user is wearing the shoes. By attaching multiple string-shaped members and tying them together, it is possible to apply pressure from the outside to the inside to the first metatarsal bone and the fifth metatarsal bone of the user.

Figure 3 is a perspective view showing the foot skeleton to which pressure is applied by the pressure-applying member 10 of the shoe 100 according to the embodiment of the present invention. As shown in Figure 3, in the shoe 100 according to the embodiment, the pressure-applying member 10 applies pressure from the outside to the inside to the first metatarsal bone (metatarsal bone of the big toe) 41 and the fifth metatarsal bone (metatarsal bone of the little toe) 45. As a result, the big toe and little toe open outward, respectively, according to the principle of leverage with the joints between the metatarsals 41, 45 and the phalanges 51, 55 as the fulcrum.

Here, it is preferable that the width of the pressure applying member 10 is equal to or less than the length L of the first metatarsal bone 41 and the fifth metatarsal bone 45 of the user, and that the pressure applying member 10 is placed at a position that does not touch the heads of the metatarsals 41, 45. If the width is equal to or greater than the length L of the first metatarsal bone 41 and the fifth metatarsal bone 45 of the user, the principle of leverage does not work even when pressure is applied, and the big toe and little toe do not spread outward, so that a so-called transverse arch shape is not formed. Even if the pressure applying member 10 is placed at a position that touches the heads of the metatarsals 41, 45, the principle of leverage with the fulcrum at the connection between the metatarsals 41, 45 and the phalanges 51, 55 does not work, which is not preferable.

When the big toe and little toe are each spread outward, the relative positions of the toes change. Figure 4 is a schematic diagram showing the positions of the toes when viewed from the front of the shoe when wearing shoe 100 according to an embodiment of the present invention. Figure 4(a) is a schematic diagram showing the positions of the toes when viewed from the front of a conventional shoe when worn on the right foot, and Figure 4(b) is a schematic diagram showing the positions of the toes when viewed from the front of the shoe when shoe 100 according to the present embodiment is worn on the right foot.

As shown in Figure 4(a), when wearing normal shoes, the toes lie flat in a position that matches the sole 60. In other words, the big toe 61 and little toe 65 are positioned at approximately the same height as the other toes, which causes problems such as poor blood flow, especially at the tips of the toes, and fatigue when walking.

In contrast, as shown in FIG. 4(b), in the shoe 100 according to this embodiment, by tightening the ribbon portion 20 threaded through the pressure applying member 10, the big toe and little toe spread outward according to the above-mentioned principle, so that the ground contact positions of the big toe and little toe are lower than the ground contact positions of the other toes. As a result, the position of the toes tends to be a so-called transverse arch shape when viewed from the front.

It is well known that the transverse arch shape improves blood flow in the feet, improves sensitivity to cold, promotes metabolism, and has the potential to have a weight loss effect. It also allows you to walk using the entire sole of your foot from heel to toe, and stimulates the calf muscles, improving swelling and improving the contours of your legs.

The shoe according to this embodiment preferably has a small gap on the outside of the user's big toe and little toe, through which the big toe and little toe can move. As shown in FIG. 4(a), there is a gap 70 on the outside of the user's big toe 61 and little toe 65, through which the big toe 61 and little toe 65 can move. This makes it easier for the big toe 61 and little toe 65 to be pushed out into the gap 70 when pressure is applied by the pressure applying member 10, and the spacing between the toes can be increased without difficulty. Therefore, the ground contact positions of the big toe 61 and little toe 65 tend to be lower than the ground contact positions of the other toes, and the position of the toes when viewed from the front can be made to have a natural transverse arch shape.

As described above, with the shoe 100 according to the embodiment of the present invention, the big toe 61 and little toe 65 land lower than the other toes, and the position of the toes when viewed from the front can be made to have a natural transverse arch shape. The natural transverse arch shape improves blood flow to the foot, preventing bunions and improving sensitivity to cold, promoting metabolism, and is expected to have a weight loss effect. It also allows the wearer to walk using the entire sole of the foot from heel to toe, and the active working of the calf muscles improves swelling and is expected to have a cosmetic effect on the lines of the legs.

The present invention is not limited to the above-mentioned embodiment, and various modifications and improvements are possible within the scope of the spirit of the present invention. For example, in the above-mentioned embodiment, the pressure applying member 10 is formed of a band-shaped member, but it is not particularly limited to this, and any shape is acceptable as long as it can apply pressure from the outside to the inside of the user's first metatarsal bone (metatarsal bone of the big toe) and fifth metatarsal bone (metatarsal bone of the little toe). However, since the pressure required to create a natural transverse arch shape varies from person to person, it goes without saying that it is desirable to have a configuration that allows the applied pressure to be adjusted.
