The present invention relates to shoes, and more particularly to shoes for posture correction and diet.

For a long time, with the development of humanity, the purpose of shoes was to protect the feet and to facilitate the movement. However, with the development of the fashion culture, shoes have taken a significant place as a part of fashion and brought a lot of changes. When shoes first came out of the world with high heels to make them look taller, they provoked a great sensation.

However, the musculoskeletal disorders of the human race began when shoes were made, and the shoes and musculoskeletal disorders are highly related. The movement starts with the center of gravity. When a person moves, he puts the weight of a part of his body in front of him, shifts the position of the center of gravity forward, and walks with this mechanism. Ideally, when you place a part of your body in front of your center of gravity, lift your legs and straighten your upper body. But in general, people who walk hurriedly or lack strength in the lower extremities will have their heads forward. If your head comes forward, your back will naturally bend and your posture will worsen.

This phenomenon is compounded by wearing high-heeled shoes. This is because high-heeled shoes already move the center of gravity forward, resulting in an unstable posture. The upper body is tilted forward and the hips are pulled back to prevent it from tilting forward. Thus the human body has two separate centerlines. One is the centerline centered around the hip joint, and the other is the centerline centered around the spine. This will increase the stress on the back can lead to back pain.

As the income level improved with the development of the industry, the basic consciousness problem was solved. However, the problems of health such as stress, adult illness, and obesity have emerged as social problems. On the other hand, with the advent of the so-called 'well-being era', interest in health is increasing at the national level. In this context, interest in exercise, posture correction, diet, etc. is now emerging as a major concern among men as well as women. In line with this social trend, so-called 'loose shoes' were invented, and when these shoes without heels were worn, the center of the foot naturally moved to the tiptoe and walked the crow's feet. Because the muscles and thighs relax repeatedly, the shoes are designed to improve muscle strength and endurance to gain diet.

If you can get a diet effect just by wearing shoes like this, it can be helpful for those who have a hard time taking time to exercise in busy daily life.

Conventional techniques related to shoes considering health include, for example, Korean Laid-Open Patent Publication No. 2003-0062765 ("Diet and Exercise Shoes"). This invention is different from the height and shape of the soles of the heel, front heel and toe soles of the shoe respectively, the height and shape of the sole during the exercise due to the increase in the exercise load on the soles to strengthen diet and fitness For shoe sole structure.

Second, the Republic of Korea Registered Utility Model Publication No. 20-0351293 ("Diet shoes"). This design makes the front of the shoe higher than the height of the heel, so that when the user wears the shoe and walks, it moves only by the front heel of the shoe. It is about diet shoes that can be made.

The two inventions are intended to induce a body posture such as standing with a so-called "crow's feet" by concentrating the weight on the heel of the foot, such as when marathons or walking, even during daily walking, which is difficult to obtain the effect of stretching or posture correction. There is.

Third, the Republic of Korea Registered Utility Model Publication No. 20-0301689 ("functional health shoes") can be mentioned. The present invention relates to a functional health shoe that inclines the insole of the shoe to balance the body during walking and enhance the circulation of blood. This invention is limited to inclining the insole of the shoe is limited to apply to a variety of shoes, there is a problem that the exercise and diet effect is difficult to obtain.

Fourth, U.S. Pat. No. 5,592,757 ("Shoe with walking sole"). This invention is to improve the pedestrian's strength, posture, and speed. The sole of the shoe is divided into the front part from the heel to the front of the heel, which is a common wedge, and the front part from the heel to the end of the toe. It's about shoes that get thicker and thinner in the front. This invention is to determine the shape of the shoe soles to improve the pace or speed, there is a problem that the effect of diet and posture correction is difficult to obtain.

Therefore, an object of the present invention is to overcome the disadvantages of the prior art as described above, by inducing the body of the person wearing shoes to the same position as when climbing high or climbing steep hills to obtain a diet and posture correction effect It is to provide shoes to make.

According to a preferred aspect of the present invention in order to achieve the technical problem as described above, in the shoe including the sole is formed only the front heel, or the front heel is higher than the heel, the front heel is the inner slope and the outer end portion Among the front heel portion, only the inner inclined portion touches the ground, so that the angle between the front heel portion and the ground is provided between 35 degrees and 40 degrees.

In addition, in the shoe including the sole is formed only the front heel, or the front heel is higher than the heel, the front heel is formed at a height such that the toes bend at an angle of 35 degrees to 40 degrees with respect to the ground when standing upright Shoes are provided.

The sole includes a first inclined portion formed from the heel portion to a position corresponding to the metatarsal bone of the wearer, and a second inclined portion formed from the first inclined portion to the forefoot portion, wherein the first inclined portion with respect to the ground It is preferably formed at an angle of 20 ± 2 degrees, and the second inclined portion is preferably formed at an angle of 35 degrees to 40 degrees with respect to the ground.

In addition, in shoes, a shoe is provided that includes the front heel only in the front portion. In addition, in a shoe comprising a sole divided into a front heel and a heel, the front heel is provided that includes a shoe formed higher than the heel.

The front heel includes a fixing protrusion on the surface corresponding to the shoe sole, characterized in that the removable fixing means is connected. In other words, the present invention by forming a high front heel to reproduce the posture, such as climbing a high hill or climbing a steep hill, the effect is exerted, which may be somewhat uncomfortable, so as to simply fix it like velcro (velcro) It is preferable to use a fixing means that can be removable.

The front heel is provided with grooves and protrusions, or preferably includes a sealed tube or spring containing air. In the shoe of the present invention, the shape, configuration, and material of the front heel are important, and a lot of materials are required, so that the front tube has air in a closed tube (aka 'air cushion') in order to give an appropriate elasticity and shock absorption function for walking. Or elastic bodies such as springs. It is not necessary to insert an elastic body in order to increase the elasticity of the fore part, and it is also possible to form the shape of the fore part to include a plurality of valleys and protrusions.

The front heel is composed of an inner inclined portion, an equilibrium portion and an outer end portion, and the height of the front heel portion is preferably formed such that only the inner inclined portion contacts the ground.

Typically, the front heel of the shoe and the parallel portion in contact with the ground; An inward inclined portion connected to a central portion which is a boundary between the heel portion and the front heel portion; It consists of a lateral end corresponding to the tip of the toe. However, the present invention is characterized in that the front shoe is formed higher than a normal shoe, and the parallel part of the front heel does not make the so-called 'crow's feet' posture, and when the shoe is worn, the entire sole of the foot touches the ground, but the ankle is Since it is to maintain the state rotated upwards, it is preferable to form the front heel high so that the parallel inclined portion of the front heel does not touch the ground but the inner inclined portion touches the ground.

When walking in the shoe of the present invention formed as described above, only the inner slope portion of the rear portion and the front portion of the sole of the shoe is in contact with the ground. Therefore, unlike the front shoe of the conventional shoe, the front shoe of the present invention may be composed of only the inner inclined portion and the outer end without the parallel portion.

When the front heel is upright, it is preferable that the toe is formed at a height such that the toe is substantially raised to the maximum height. The shoe of the present invention has the core of the invention to maintain a posture when climbing a mountain or climbing a steep hill just by wearing a shoe, so the height of the front heel is higher. However, when the body structure is upright, it is preferable that the toe can be substantially raised to the maximum height, and if the front heel is higher than that, it may be impossible to walk upright while wearing shoes or to wear itself.

According to another preferred aspect of the present invention there is provided a shoe insole comprising the front portion of the foot is formed higher than the rear portion and a shoe comprising the insole.

The insole of the shoe may include a foot acupressure projections. Since the present invention relates to shoes that are beneficial to health just by wearing shoes, it is preferable to form a plurality of protrusions for foot acupressure on the insole portion of the shoe that the human foot directly touches, whereby the effect of the present invention is further improved. Can be doubled.

In addition, the insole of the shoe may include any one or more components of bioceramic or silicone or ocher or charcoal. Insoles of the present invention can be produced in a variety of materials, but it is beneficial to the health to make the best use of the invention, bioceramic, silicone, ocher, charcoal, etc. are known to have the effect of deodorization, antibacterial, dehumidification, etc. It is desirable to include the material of. However, the technical idea of the present invention is not limited to the above materials.

Hereinafter, preferred embodiments of the shoe according to the present invention will be described in detail with reference to the accompanying drawings, in the description with reference to the accompanying drawings, the same or corresponding components are given the same reference numerals and duplicate description thereof. Will be omitted. In addition, the structure of the shoe according to the present invention will be described first before describing the preferred embodiments of the present invention in detail.

Normally, the normal ankle has about 20 degrees of dorsal flexion in a neutral orthogonal position. The range of motion of the entire dorsal flexion is about 35 °, but it can bend more depending on the individual's muscle development and degree of flexibility. The powerful muscles that move the ankles are located in the front and back of the legs, so they repeat contraction and relaxation while walking. The angle of the heel of the shoe according to the present invention has a double lever structure of 20 degrees at the position of the neutral right angle, and the angle of the metatarsal bone is 58 degrees.

When the ankle is flexed on the dorsal side, the metatarsal bone is also bent along the ventral side. Joint flexibility is also divided into active and passive flexibility. Active flexibility is the range in which the joint can move on its own, and passive flexibility is the movement of the joint by pulling or bending it more. Therefore, the joint may stretch or bend more if you or someone else pulls or bends it. The shoe according to the present invention, once the dorsiflexion in the heel, and the more dorsiflexion in the front dream, so you can mobilize the muscles of the lower extremity, which is mobilized when the ankle and toe ventrally flexed.

Therefore, the biggest feature of the shoe according to the present invention is to allow a person to move to the maximum range of ankle movement that a person can walk while wearing.

1 is a conceptual diagram comparing and analyzing a force vector when walking shoes and when wearing shoes according to an embodiment of the present invention. Shoes according to the present invention has a greater angle between the heel and front heel than normal shoes. Combining the force vector in the heel and heel of the shoe according to the present invention, the magnitude and direction of the force, such as 'A' of Figure 1 remains. The combined force has the direction of force rising vertically along the Achilles tendon from the heel. This means that wearing the shoe according to the present invention allows the muscles in the back of the leg to be strongly extended. Looking at the synthesis of the force at the tip of the toe on the left side of Figure 1 can be seen that the big tore using the toes.

However, if you combine the forces in the heel and heel when walking barefoot as shown in the right side of Figure 1 it can be seen that each other, such as 'B'. In addition, the synthesized force at the tiptoe can be seen that when the shoes according to the present invention is pulled up with a greater force.

Hereinafter, the experimental results of the mechanism of the shoe according to the present invention effective in posture correction, blood circulation, walking, weight control and experiments on the difference between the existing walking shoes, high-heeled shoes and shoes according to the present invention Explain the results.

1. Effect of shoes according to the present invention on posture correction, gait, weight control, blood circulation

A. Effect of shoes according to the present invention on posture correction

1) Mechanism that brings the center of gravity line to agreement

High-heeled shoes bring the center of gravity back when walking, allowing the center of the hip joint and the center of the spine to be in line so that the centerline of the human body matches. This is the first advantage of high shoes.

2) strengthening abs and back muscles

The correct posture of a person is a line that connects the ear ball, the center of the shoulder joint, the waist, the center of the hip joint, the center of the knee joint, and the peach bone.

Bad postures are usually due to weak abdominal muscles. The muscles needed to maintain a good posture are abs, lumbar muscles, thigh anterior and thigh hind. Therefore, it is necessary to strengthen these muscles for proper posture and walking. However, it is not easy for the young women to do abs and back exercises as well as the elderly who have weakened muscle strength.

The shoe according to the invention brings the center of gravity back because of the high heel (of course the center of gravity is in the human body). At this time, the muscle is controlled autonomously to balance without falling down. In the process of controlling the muscles, the abdominal and lower back muscles located in the very center of the body is contracted, relaxed and controlled. It also regulates muscles to balance autonomously, so you can use them more effortlessly than other muscle strengthening exercises. Therefore, it is possible to strengthen the abdominal muscles and the lower back muscles only by wearing low back pain patients, lowering the pain even by wearing the effect can be easily worn by the elderly as shown in Figures 2a and 2b.

3) Femoral quadriceps contraction and strengthening of the extensor muscle

The muscles necessary to maintain the body's correct posture include the quadriceps (Quadriceps) and the hamstrings in the lower leg, in addition to the abs and back muscles. Shoes according to the present invention with a high front makes the dorsal flexion of the ankle so that the quadriceps muscles contraction than the normal shoes and the swarovski muscles.

Thus, the quadriceps muscles are strengthened, improve the power of the temple. As shown in FIGS. 2A and 2B, the flexibility of the slender muscle in the elderly was compared with before and after 5 weeks of wearing the shoe according to the present invention. It can also be seen that the knee flexibility is also greatly increased.

4) increased flexibility of the elderly

The range of motion of the waist and thigh of a 76-year-old woman with osteoporosis was measured at a university hospital in Seoul. The elderly woman had severe osteoporosis and had spinal surgery and two months later she had a spinal flexibility test. I could hardly bend or turn my back at this time. After another two months, the first time the shoe according to the present invention was worn, but it was possible to walk with a plastic support in the form of a vest from waist to chest by holding a cane.

Starting from this time, three to five times a week, once 30 minutes in the house wearing a shoe according to the invention was carried out walking exercise. After about three months, the degree of flexion of the waist forward increased so far that hands could reach the ground. Spinal flexion, extension, lateral flexion, rotational ability can all be seen that increased. In addition, the increased flexibility in the back of the thigh allows you to lie down and lift your legs more than 90 degrees.

B. Influence of the shoes according to the present invention on walking

1) strengthening the dorsal flexors and toes muscles of the ankle

Correct walking is called 'three-time walking'. That is, when the foot touches the ground, it touches the heel first, then the entire sole of the foot, and finally pushes the ground back toward the heel of the foot. However, immature infants or older muscle-degraded infants walk with only the second stage of these triplets. This is called 'foot sole walking'. This is because the ankle joint is the latest development of the joint used for walking, and the first degeneration is the ankle joint.

When walking in shoes according to the present invention because the front heel is high because the heel of the ankle joint just be wearing shoes, when the ankle is bent on the back side of the toes naturally come up, so the ankle and toe joint movement Together. This is the third advantage of the shoe according to the present invention.

2) Strengthening Achilles tendon and three calf muscles

Shoes according to the present invention is high in the heel, the shoe is more bend than the normal shoes to balance and prevent the back of the center of gravity to fall back. At this time, the Achilles tendon is pulled more, and the calf muscles attached to the Achilles tendon are pulled together, so that not only the Achilles tendon but also the calf muscles can be strongly stretched together. This is similar to the way athletes squeeze and squeeze the soles of their feet where they have their jaws for Achilles tendon and calf muscle stretching after training.

3) Temple of the knee extension muscles

The hamstring of the leg is the lozenge space just behind the knee. The upper border is bounded by the tendons of the thigh biceps (femoral biceps) on the outside, and the tendons of the apex and half tendon muscles on the inside, and the lower border is the inner branch of the calf muscles on the inside, It is made by the forked branch of the calf muscle, the calf comb, and the penis. The characteristics of the elderly posture and gait are due to the fact that they do not spread.

Shoes according to the present invention is high in the heel, so the ankle joint is flexed to the back of the Achilles tendon from the Achilles tendon to stretch the muscles of the back of the calf so that it is effective in improving the posture and gait of the elderly.

C. Effect of the Shoes on the Blood Circulation of the Present Invention

1) Effect on hillsides-high energy consumption

Shoes according to the present invention with a high heel on the hill road muscles of the lower extremity of the lower extremity, the muscles of the lower extremity of the lower extremity contract more strongly, resulting in an increase in the amount of exercise.

In general, to increase the intensity of the exercise is to increase the speed or add weight. However, there are ways to increase your strength without increasing your speed and weight. That is to climb the sloped hill. Shoes according to the present invention has an effect such as walking on a sloping road with a high heel.

Even with the same walking, the amount of exercise varies depending on the walking speed, ground conditions, and slope. For example, 51 kg of female college students measured energy consumption when they walked for 60 minutes.The result is 107kcal at 1.6km / 20min (4.8km / h), 90kcal at 1.6km / 26min (3.24km / h) and asphalt. It is 146kcal on the road, 90kcal on the downhill, 166kcal on the grass track, 139kcal on the ground and 214kcal on the uphill. At this time, it can be seen that the uphill road has the largest calorie consumption. The energy consumption on the uphill road is similar to jogging at 1.6km / 13min (7.38km / h).

2) Pressure distribution during blood support of the shoe according to the present invention-blood circulation

Figure 3 is a graph comparing the distribution of the pressure applied to the soles when wearing shoes and general sneakers according to an embodiment of the present invention. 3 shows a double limb support. Comparing the two graphs of Figure 3 can be seen that the pressure distribution moves from the heel to the front heel when walking in general sneakers. As the pressure of the right foot moves forward, the pressure does not apply to the heel of the right foot but instead to the heel of the left foot.

However, when walking with shoes according to the present invention, both feet supporters can see that the pressure of the right foot still remains on the heel while the movement of pressure is passed to the left foot, so that the pressure distribution time on the heel is long. These results increase the ankle flexing time because the heel is higher than the general sneakers when walking shoes according to the present invention, it increases the time to support the heel, and as a result, the back of the leg stretches throughout the support The front part will contract.

Stretching for 20 seconds x 2 causes a 1.4-fold increase in blood flow than resting blood flow, and peaks in blood flow are reported to be 3-5 minutes after stretching. This support has a long stretching time. As a result, it is very effective for blood circulation because it stretches and flexes the lower limbs.

3) the effect of shoes according to the invention on venous blood

Muscle is called the second heart. The muscle contraction and stretching will help blood flow. As shown in FIG. 3, the shoe according to the present invention has a high front heel and thus lengthens the time taken for pressure on the heel, thus inducing a long stretch of the ankle.

Muscles after stretching are contracted. When the muscles in the limbs contract, the valve in the vein opens, causing blood to flow to the heart against gravity. In this process, shoes according to the present invention can improve blood circulation even if the same exercise than the general sneakers can be improved vascular diseases such as venous blood.

4) heel meridian long-term stimulation-uterus (menstrual discomfort), large intestine (constipation), bladder function (urinary incontinence)

Compared to other sneakers shoes according to the present invention is to give a continuous stimulus to the heel to continuously stimulate the meridians distributed over the heel for a long time. The heel has a meridians that governs the genitals of the man, the uterus of the woman, the large intestine, the bladder, and wearing shoes according to the present invention can continuously stimulate the heel to improve the health of these parts.

D. Effect of the Footwear According to the Invention on Shock and Pain

1) Load on the ankles and knees downhill

Figure 4 is a photograph comparing the change of the ankle and knee angle when downhill when wearing shoes and general sneakers according to an embodiment of the present invention.

People with knee pain or those with degenerative arthritis especially dislike going down stairs or going downhill. This is because you feel more pain in your knees. However, if you go downhill wearing a shoe according to the present invention, since the front heel of the shoe is already high, there is almost no change in the angle of the ankle and knee actually moving, and the width of the ankle and knee movement is small (upper side of FIG. 4). . On the other hand, when descending downhill wearing normal sneakers, the ankle and knee angles are larger than the shoes according to the present invention, so that the width of the movement is large (lower side of FIG. 4). Therefore, when coming downhill wearing normal sneakers, the range of angular movements of the ankle and knee is greater than the shoes according to the present invention, so the amount of motility may be greater, thereby increasing the pain.

2) impact force, impact load ratio, active force magnitude, active load ratio of shoes according to the present invention

Impact force is the maximum force applied within 50ms of the moment the foot touches the ground. Since the impact force appears at a shorter time than the muscle incubation period, the muscles do not respond to the impact force and are known to be a major cause of acute injury.

The force load factor is the slope of the force exerted by the time it reaches, and can be defined as the magnitude of the force exerted over a period of time. This load rate can be divided into two types: impact load rate and active force load rate. If the impact load rate is large, it means that a large impact has been received for a short time. If the force load rate is large, an active big force is expressed for a short time. The following table compares the load ratio of shoes according to the present invention with general walking and jogging.

Kinds time Load factor General walking jogging invention sneaker invention invention slipper 52ms 44ms 63ms 27ms 9.02bw / sec 43.87bw / sec (Shock Load Rate) 18.58 bw / sec 48.59bw / sec (Muscle Load Rate)

Sneakers according to the present invention is twice the load rate than normal walking. This means that the sneaker according to the present invention can actively exert about twice as much force as the general sneaker.

Slippers according to the present invention shows a similar load rate to jogging. However, while the jogging load rate is an impact load rate, the slipper load rate according to the present invention is an active load rate, and there is no impact, but the active force load rate is large, and thus it can be seen that it is advantageous to make a large force active for a short time.

E. Pressure distribution during walking of shoes according to the present invention-reduces sole fatigue

Figure 5 is a graph showing a comparison of the pressure distribution when walking and wearing shoes and general sneakers according to an embodiment of the present invention. The color indicates the magnitude of the pressure. The pink pressure is the highest (30N / cm ² ) and the black pressure (2N / cm ² ) is the smallest.

When walking in regular sneakers, you can see the greatest pressure on the heels, heel, and big toe. However, when walking in the shoe according to the present invention, the distribution of red color is not seen, and it can be seen that the pressure distribution is low, as seen from the pressure of green (10N / cm ² ). This is because the shoe according to the present invention has a high front heel, and when the foot touches the ground, the entire surface connecting the metatarsal bones from the heel touches. Small pressure on the soles can be said to reduce the fatigue of the soles. Therefore, the shoe according to the present invention can be said to be suitable for people who are overweight or diabetic, so as to reduce the pain of the sole even when walking for a long time.

2. Differences between shoes according to the present invention and conventional heelless shoes, general walking shoes

A. Pressure distribution by plantar site

Figure 6a is a graph showing a comparison of the pressure distribution when walking and wearing shoes (left) and the conventional heelless shoes (right) according to an embodiment of the present invention, Figure 6b is a conventional heelless This is a graph comparing the pressure distribution when walking with shoes (left) and walking shoes (right).

Looking at the distribution of pressure on the sole of the shoe according to the present invention, as shown in Figure 6a is distributed in the pressure of about 15N / cm ² of the yellow on the heel, conventional shoes without the heel is 22N / cm of red on the heel The magnitude of ² appears. In the case of a shoe without a conventional heel as shown in FIG. 6b, the pressure on the heel is not different from that of general sneakers, but rather, the pressure is greater than that of general sneakers.

B. Pressure distribution by plantar part (mountain)

Figure 7a is a graph comparing the pressure distribution for each foot part of the shoe (left) and the conventional heelless shoe (right) according to an embodiment of the present invention in a mountain format, Figure 7b is a general shoe (left) It is a graph comparing the pressure distribution of each foot part of the shoe without the heel and the conventional heel in mountain form.

7A and 7B, the shoes according to the present invention show a large pressure only at the heel of the sole, but the conventional heelless shoes and the general shoe can be seen that the pressure at the front heel of the sole is large. It can be seen that the shoes without conventional heels are not so different from ordinary shoes.

C. Ground reaction

Active load of the shoe according to the present invention is significantly higher than the bare feet or shoes without a conventional heel is effective to give a large force for a short time, it can also be said that the momentum is also large.

8 is a side view showing a shoe including only the front heel according to the first embodiment of the present invention. Referring to FIG. 8, the sole 100, the front heel portion 110, the inner slope portion 111a, the parallel portion 111b, and the outer end portion 111c are illustrated. This embodiment shows the shoe that the front heel 110 is coupled only to the front portion of the shoe sole 100, when the body of the person wearing the shoe climbs or climbs a steep hill by raising the front heel 110 to the shoe. Will maintain the posture.

In other words, the muscles of the back of the body, such as the calf is relaxed and the abdominal muscles are contracted to achieve the effect of stretch and diet. The front heel portion 110 according to the present embodiment is flattened so that the inner slope portion 111a extends toward the outer end portion 111c to reach the ground, and only the inner slope portion of the front heel is walking when wearing shoes. Since the 111a touches the ground, the walking mechanism is different from that of the existing shoes.

That is, when walking with existing shoes, the heel part touches the ground, the parallel part of the front heel touches the ground, and then the toe falls off the ground from the heel part and finally falls off the ground. On the other hand, in the case of the shoe according to the present invention is to walk in the state of raising the tip of the toe as far as possible so that the heel touches the ground and only the inner inclined portion (111a) of the front heel 110, after contact with the ground,-the front heel ( The parallel portion 111b of 110 does not touch the ground-it is separated from the ground from the heel portion.

Figure 9a is a side view showing a shoe formed with a front heel higher than the heel according to a second embodiment of the present invention, Figure 9b is a front heel portion of a shoe formed with a front heel higher than the heel according to a second embodiment of the present invention Side view showing the inclination angle. Referring to FIG. 9A, the sole 100, the front heel 110, the heel 120, the inner slope 111a, the parallel 111b, and the outer end 111c are illustrated. This embodiment is the same as in the first embodiment by forming the front heel 110 thicker than the heel 120 in the shoe sole 100 is formed both the front heel 110 and the heel 120 Shape shoe structure can be obtained.

The core of the technical idea of the present invention is to increase the height of the front heel 110, but when actually walking when the heel 120 is also used, thus forming the heel 120, but the front heel 110 more than that It is preferable to form thickly. In this embodiment, as in the first embodiment, the inner inclined portion 111a extends toward the outer end portion 111c of the front heel 110 so that only the inner inclined portion 111a touches the ground when walking. The present embodiment is a case where the front heel of the sneaker is formed high, but the present invention is not limited to the type of shoes.

Shoes according to the present invention is characterized in that it comprises only the front heel 110, or the front heel 110 has a sole 100 formed higher than the heel 120, the front heel 110 to the ground The inclined angle is formed at a height such that the tip of the toe is bent at the angle of 35 degrees to 40 degrees with respect to the ground when the shoe according to the present invention is worn upright. As shown in FIG. 9B, theoretical studies and experiments on shoes according to the present invention showed that the inclination angle of the front heel 110 ('A' in FIG. 9B) was 35.76 degrees. Therefore, in consideration of manufacturing error or deviation depending on the human body structure, the angle of the front heel 110 is preferably 35 degrees to 40 degrees.

If the angle of the forefoot portion is less than 35 degrees, the effect of posture correction, diet, etc. according to the present invention is lowered. If the angle of the forefoot portion is greater than 40 degrees, walking is difficult to sufficiently derive the effect according to the present invention.

On the other hand, in the present embodiment, the front heel portion 110 includes the inner slope portion 111a and the outer end portion 111c, and the front heel portion 110 by touching only the inner slope portion 111a on the ground in the front heel portion 110. ) Can be inclined upward, in this case, the angle formed by the front heel 110 with the ground is preferably 35 degrees to 40 degrees as described above.

In addition, according to the anatomical study of the human foot, the sole 100 of the shoe according to the present invention preferably comprises a first inclination and a second inclination to form a double inclination, the first inclined heels The portion 120 is formed to a position corresponding to the metatarsal bone of the wearer, and the second inclined portion may be formed from the first inclined portion to the forefoot portion.

As described above, the first inclined portion is formed at an angle of 20 × 2 degrees with respect to the ground to allow the toe to bend at an angle of 35 degrees to 40 degrees with respect to the ground when the shoe according to the present invention is worn upright. The two inclined portions are preferably formed at an angle of 35 degrees to 40 degrees with respect to the ground.

10A is a perspective view of a shoe including a fixing protrusion and a detachable fixing means according to a third preferred embodiment of the present invention, and FIG. 10B includes a fixing protrusion and a detachable fixing means according to a fourth preferred embodiment of the present invention. Side view showing a shoe. 10A and 10B, the sole 100, the front heel 110, the detachable fixing means 112, and the fixing protrusion 113 are illustrated. This embodiment is configured so that the front heel 110 is attached to the front heel 110 when used for the purpose of exercise or the like, usually by using a normal shoe by constructing a removable. Removable fastening means is preferably a velcro that is widely used in sneakers, sandals, etc., but is not necessarily limited thereto.

Meanwhile, a fixing protrusion 113 is formed on a surface corresponding to the sole 100 in the detachable front sole 110 to prevent the front sole 110 from moving integrally with the sole 100. have. The fixing protrusion 113 is preferably a shape such as a nail or a needle when it is intended to be used in general shoes, but in the case of a dedicated shoe on the premise of detachment of the front heel 110, the corresponding unevenness (凹凸) in the front heel What is necessary is just to form in the part 110 and the sole 100 of shoes, respectively.

Figure 11 is a side view showing a shoe formed with a groove and a protrusion in the front heel according to the fifth embodiment of the present invention. Referring to FIG. 11, the front heel 110, the front heel groove 114, and the front heel protrusion 115 are illustrated. Since the front heel 110 of the shoe of the present invention is to be made to walk or cantilever in a fixed state with the toe upwards, the front heel 110 is not necessarily formed tightly. Therefore, in order to increase the elasticity of the forefoot portion and to save material, the present embodiment includes the forefoot portion 110 having a plurality of protrusions 115 and grooves 114. However, the number and shape of the protrusions 115 and the grooves 114 is not necessarily limited to this embodiment.

12 is a side view showing a shoe including an air cushion in the front sole according to a sixth preferred embodiment of the present invention, Figure 13 is a side view showing a shoe formed with a gap in the front sole according to a seventh preferred embodiment of the present invention to be. 12 and 13, the front heel 110, the air cushion 116, and the void 118 are shown. In order to increase the elasticity of the forefoot portion, it is preferable to include the air cushion 116 which is commonly found in conventional sneakers. Even without the air cushion, the corresponding space 118 may increase the elasticity of the forefoot portion.

As such, the element for increasing elasticity can be said to be a very important component for shock absorption in a shoe that induces walking without moving the ankle as in the present invention. However, the method of increasing the elasticity of the front heel is not necessarily limited to the present embodiment, and shock absorbing methods through all known types of elasticity may be applied.

Figure 14 is a use state diagram showing the state wearing a shoe in accordance with a preferred embodiment of the present invention. As shown in FIG. 14, the shoe according to the present invention maintains a state in which the ankle is rotated upward when upright, thereby inducing a body posture such as climbing a mountain or climbing a steep hill.

15 is a perspective view showing a shoe insole formed so that the front portion of the foot is higher than the rear portion according to a preferred embodiment of the present invention, Figure 16 is a side view showing the shoe using the insole shown in FIG. As shown in FIG. 15, the insole of the shoe is formed to be higher than the rear part, and the same effect as that of the shoe of the present invention can be obtained by attaching it to various shoes as shown in FIG. In this case, the angle of the foot is directed upward only in the inside of the shoe, and since the outside of the shoe looks similar to a normal shoe, it is possible to fully enjoy the effects of the present invention even when going out without a feeling of rejection of the design.

The shoe of the present invention comes from pain in the calf, even walking about 10 minutes, the force is entered into the belly. Therefore, even if you walk only 10 minutes to 30 minutes a day wearing the present invention can achieve an exercise effect equivalent to running for about 1 hour to 2 hours. The above examples illustrate preferred embodiments of the present invention and are not intended to limit the present invention. Shoes of the present invention can be applied to all kinds of shoes, such as shoes, sneakers, slippers, sandals.

According to the present invention having the configuration as described above, because a posture similar to climbing a high hill or climbing a steep hill just by wearing shoes is maintained, muscles are formed in the calf and the thighs and hips are forced into the waist. Balance and lower belly obesity is effective. In addition, because the power is concentrated on the tip of the foot when walking to form a posture, such as ergonomically exercise naturally, the waist is slim, elasticity in the hips, and can also provide a diet effect.

In addition, because the front heel is formed higher than the heel, the movement of joints and muscles when walking is similar to that of walking backwards, leading to the use of less-used muscles, thereby promoting balanced development of the body, promoting blood circulation, and posture. There is an effect such as correction.
