Abstract

<P>PROBLEM TO BE SOLVED: To provide footwear having a shape for reinforcing the basic muscle strength of a foot in doing sports by recovering the decline of muscle strength in sole, which is required to perform original walking such as kicking the ground by putting power into toes with the movement of the center of gravity in walking, and urging a user to perform heal-to-toe motion walking in a correct posture. <P>SOLUTION: A level difference being not less than 15mm in height is arranged along a part from an interphalangeal joint to a metatarsophalangeal joint (the root of toe) in each toe concerning not less than one of the outsole, insole, and a sole insert. An arbitrary angle from verticality is obtained in a step surface and the upper part of the step is chamfered. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention relates to footwear that facilitates weight transfer and strengthens each muscle of the foot.

Some conventional footwear aimed at strengthening leg muscle strength has a step and a foot portion deleted from the bottom (see, for example, Patent Document 1).

However, since the depth of the footstep of this footwear is 1mm to 12mm, preferably 3mm to 8mm, the foot is in contact with the foot and the refractive motion of the toes is reduced, which is important for strengthening toe muscle strength. Because the exercise of muscle stretch is small, the results of strengthening leg muscle strength are low, and the weight shift during walking is also small, and it seems that the improvement of walking ability cannot be sufficiently achieved. In addition, even if it is shallow, there is a step, so the sole of the foot moves to the tip side of the footwear when it is used, and the position of the toe and the step is displaced, and there is no function to prevent it. It plays its role, but if used for a while, it will loosen the nose and become ineffective.
JP 2000-4902 A.

Therefore, if the step is shallow, the refractive motion of the toes becomes small, and the exercise of stretching the leg muscles, which is important for strengthening the toe muscle strength, is also small, so that the strengthening action of the foot muscles cannot be solved.

There has been a demand for a solution to the problem that weight movement during walking cannot be achieved due to the footsteps hitting the footstep and sufficient weight movement cannot be achieved.

There has been a demand for a solution to the problem that the sole of the foot moves to the tip side of the footwear during use and the position of the toe and the step is displaced due to the difference in level even when shallow.

At least 15 mm in height along each toe base between the interphalangeal joints of the toes (base of the toes) and at least one of the footwear base, insole and insole Footwear characterized in that a step is provided, the step surface is provided at an arbitrary angle from the vertical, and the upper part of the step is chamfered.

In order to solve the above problems, the interphalangeal joint of each toe 15 in FIG. 1 and 15 in FIG. 3 to the middle toe joint (the base of the toe) between 1 in FIG. 1 and 1 in FIG. 2 in FIG. 1, 2 in insole 1, 1 or more insole and insole 12 In FIG. 12, position 13 in FIG. 12 is cut and deleted. 4-6, the height of 15 mm or more along the toes, and the step surface 4 in FIG. 1, 4 in FIG. 2, and 4 in FIG. 90 degrees, preferably 75 degrees to 85 degrees are provided, and if the angle is 91 degrees or more, there is no effect because the toes are difficult to refract. Further, the step 3 in FIG. 2 and 3 in FIG. 3 are chamfered.

The footwear according to claim 1, wherein an arch portion of a specific part of the sole is raised in an arc shape on one or more of a base part, an insole, and an insole on which the sole touches, and a part of the specific part heel is Footwear characterized by a concave shape to match the foot shape.

Footwear base part 2 in FIG. 1, insole 2 in FIG. 1, insole FIG. 12 in one or more arches at specific parts of the sole 7 in FIG. 4 and 7 in FIG. 9 of FIG. 6 and 9 of FIG. 6 2 of FIG. 1, 2 of insole FIG. 1, 1 mm to 5 mm, preferably 3 mm in an arc shape from the front part of insole FIG. 12 9 9 of FIG. 5 and 9 of FIG. 4 and 5 in FIG. 5 and 8 in FIG. 5 along the foot shape. Footwear stand 2 in FIG. 1, 2 in insole 1 and 1 mm from the front of insole 12 5 mm, preferably 3 mm, as shown in FIG. 5 and FIG.

The footwear according to claim 1, wherein an elastic material capable of forming a step when the footwear is used is provided on one or more of the foot, the insole, and the insole of the footwear according to claim 1.

1 of FIG. 1, 2 of insole 1 of FIG. 1, 2 of insole FIG. 12, 11 of FIG. 7 and 11 of FIG. 8, 12 of FIG. 9, 12 of FIG. 10 and 12 of FIG. Thus, an elastic material (soft material such as sponge) that can form a step is provided.

In the present invention, during walking, the interphalangeal joint of each toe can be sufficiently refracted from 15 in FIG. 3 to the middle toe joint (toe base) in FIG. Make an angle that makes it easy to grip 4 and press strongly. This refraction exercise has the effect of strengthening and improving the muscles of the legs (triceps muscle, hamstrings, gluteal muscles) connected to the footbed muscles by stretching and contracting the footbed muscles to strengthen the foot muscle strength. In addition, the ability to move easily makes walking easier and strengthens the basic muscle strength of the foot in all sports.

When the footwear of the present invention is used for walking, each toe foot grips the stepped surface 4 and repeatedly presses and presses it strongly, so that the entire foot moves to the tip of the footwear and the fingerpad securely grips the stepped surface 4. 5 in FIG. 5 and 9 in FIG. 6 and indentation 10 in FIG. 5 and 10 in FIG. 6 and 9 in FIG. 10 and 9 to 10 in FIG. 6 do not hinder the strengthening action of the footbed muscle strength.

Closed form (occlusive) FIG. 9 footwear and / or open footwear Figure 10 2 in FIG. 1, 2 in insole 1, 2 insole 12, 11 in FIG. 7 and 11 in FIG. 9 in FIG. 9 12 in FIG. 10 and 12 in FIG. 11 are provided with an elastic material (soft material such as sponge) capable of forming a step, so that when the footwear is used, the toes touch the footbed. A psychological feeling is given to the user psychologically, and various types of design painting can be performed on the surface of the elastic material 12 in FIG.

The shape of the foot varies depending on the person, and the closed type (occlusion) of the invention Figure 9 Footwear and / or the open footwear Figure 10 Steps 3 and 4 of Figure 1 are also diverse, so it is made to order in addition to the standard type The material is closed (closed). Material and a dedicated cutter are prepared for the insole of FIG. 9 and the dedicated ruler is formed along the toes with the universal ruler sandwiched between the positions 6 in FIG. The part of FIG. 12 is cut off and used by a cutter. Further, the stepped shape of the closed type (occlusive) footwear FIG. 9 and / or the open footwear FIG. 10 can be made by the user by making a mold by placing a free ruler between the positions 6 in FIG. 4 along the toes. The footwear that strengthens the leg strength can be made.

If a person with low back pain wears an insole made of hard rubber with a step of 15 mm on a conventional sneaker, the center of gravity can be moved easily, so there is no burden on the waist.

In the case of standing work, when I tried an insole with a step of 18 mm, the center of gravity movement was good, but the muscles of the legs (triceps, hamstrings, gluteal muscles) were used suddenly, so the whole leg was stuck.

When the slipper was provided with a step of 15 mm, the effect of tightening the calf portion of the foot was obtained.

In the case of walking, walking with a sneaker with an insole with a step of 15 mm has the effect of moving the legs forward. Also, it is comfortable because there is no resistance at the fingertips while driving.
