Abstract

The characteristics of a footwear for health is that the sole is higher on front, lower on rear, higher on out, lower on enter. When the wearer standing on the ground level, the front of foot is higher than the heel, the outer of the foot is higher than the inner of the foot, so the centre of gravity of the body moves to the inner of the rear of the foot, again adjust the tension of the muscle of the waist and back, the backbone stretch straight. Wearing often the footwear the posture of the standing and walking can be corrected, the muscle of the waist and back can be enhanced, chronic lumbago can be prevented, relaxed, treated and sick of cervial vertebra, curative effect are stable and not recurrent. Slimly effect for an adult can be took, recover the figure for the woman of postpartum and orthopaedic for the youngsters are very good.

Description

Technical field of fitness shoes

The present invention relates to a fitness shoe, and more particularly, to a fitness shoe in which the relative average load-bearing height of a sole and a rear end of a shoe varies.

Background technique

For the convenience of description, the sole part of the shoe is divided into seven parallel sections according to its load bearing degree. The names of the sections from front to back and their front-to-back length to the total front-to-back length of the sole are: front, 12 %; Palm front, 12%; forefoot, 16%; back of palm, 10%; waist back, 25%; hind palm, 13% and back, 12%.

Nowadays, the average height of the rear end of the well-known footwear products is higher than the average height of the forefoot. The average height of the flat shoes is only the same as the average height of the rear end. , Haven't seen footwear products with an average height of the forefoot higher than the average height of the back, and the same is true when people wear (bear). Moreover, there have been no reports of using shoes to correct standing, walking, treating and preventing chronic low back pain and cervical spondylosis.

The object of the present invention is to provide a fitness shoe, which can effectively correct standing and walking postures, treat and prevent chronic low back pain and cervical spondylosis.

In the description of this specification, the following terms are used-The term "average forefoot weight" refers to the upper surface of the forefoot section of the sole when the shoe is placed on a horizontal ground (that is, the contact surface with the feet, socks, or insoles when worn) , Also the bottom surface of the inside of the shoe) in the state of bearing an average weight of 1.5 kg per square centimeter, the average height from the ground, in millimeters;

The term "rear average load-bearing height" means that when the shoe is placed on a horizontal ground, the upper surface of the rear end of the sole (that is, the contact surface with the feet, socks or the last when worn, and also the bottom surface of the shoe) The average number of heights above the ground when a square centimeter bears a weight of 3 kg, in millimeters;

The medial and lateral sides of the forefoot refer to the left and right sides divided by the vertical bisector of the boundary between the forefoot and the palm; According to this division, the right side of the right foot is the outer side and the left side is the inner side, and the left side of the left foot is the outer side and the right side is the inner side. That is, the side where the thumb of the foot is located is inside, and the side where the fifth finger of the foot is located is outside.

The term "average load-bearing height of the inside of the forefoot" refers to the upper surface of the inside part of the forefoot of the sole when the shoe is placed on a horizontal ground (that is, the contact surface with the feet, socks or an insole when worn, which is also the bottom surface of the inside of the shoe). The average number of heights above the ground under a weight of 1.5 kg per square centimeter, in millimeters;

The term "average load-bearing height of the outer side of the forefoot" refers to the upper surface of the outer part of the forefoot of the sole when the shoe is placed on a horizontal ground (that is, the contact surface with the feet, socks, or an insole when worn is the bottom surface of the shoe's interior) The average number of heights above the ground under a weight of 1.5 kg per square centimeter, in millimeters;

The term "average load-bearing height at the inner side of the rear end" refers to the upper surface of the inner portion of the rear end of the sole when the shoe is placed on a horizontal ground (that is, the contact surface with feet, socks, or insoles when worn, and also the inner bottom surface of the shoe). The average number of heights above the ground when a square centimeter bears a weight of 3 kg, in millimeters;

The term "average load-bearing height at the outer side of the rear end" refers to the upper surface of the outer portion of the rear end of the sole (that is, the contact surface with feet, socks, or insoles when worn, and the inner bottom surface of the shoe) when the shoe is placed on a horizontal ground. The average number of heights above the ground when a square centimeter bears a weight of 3 kg, in millimeters.

The average load-bearing height mentioned above is the average value calculated by using the weighted average method with a square centimeter as the sampling unit. In addition, the term "average weight-bearing thickness of the hind palm" refers to the average thickness of the hind palm when it bears a weight of 3 kg per square centimeter.

The term "back end average load thickness" refers to the average thickness of the back end when it bears 3 kg per square centimeter. The above average load-bearing thickness is an average value calculated by using a weighted average method with a square centimeter as a sampling unit.

The backward tilt angle of the sole refers to the angle at which the sole is tilted backward when the shoe with the current average load-bearing height higher than the rear-end average load-bearing height is placed on a horizontal ground. The calculation method of this angle is: the midpoint of the former palm inner and outer dividing line and the mid point of the rear inner and outer dividing line are the reference points, and the average load-bearing height of the front palm and the rear end is the height position of these two points. The angle between the extension of the dot line and the horizontal ground is the backward tilt of the sole.

The forefoot inclination angle refers to the angle at which the forefoot is inclined inward when the shoes with the average weight bearing height outside the current palm are higher than the weight bearing height inside the forefoot. The calculation method of this angle is: Make the vertical bisector of the inner and outer boundary line of the forefoot, use the midpoints of the vertical bisector inside and outside as the reference point, and take the average load bearing height of the inside and outside as the height position of these two points. The angle between the extension line connecting the two points and the horizontal ground is the forefoot inclination.

The rear inclination angle refers to the angle at which the rear end inclines inward when shoes with an average load bearing height outside the rear end that is higher than the average load bearing height inside the rear end are placed on a level ground. The calculation method of this angle is: make a vertical bisector of the inner and outer boundary lines at the rear end, take the midpoints of the vertical bisector at the inner and outer sides as reference points, and take the average load bearing height at the inner and outer sides as the height of these two points, The included angle between the two-point extension line and the horizontal ground is the forefoot inclination. A kind of fitness shoes, the average load-bearing height of the forefoot is higher than the average load-bearing height of the rear end by 1-75 mm.

Due to different foot shapes and foot sizes, different walking habits, and different degrees of body defects, to accommodate more people, the difference between the average weight of the forefoot and the average weight of the rear end should be changed within a reasonable range.

When the average weight-bearing height of the front palm is higher than the average weight-bearing height of the back end by 1,125 mm, it is suitable for the relief and treatment of patients with mild chronic low back pain. It also has the health-care effects of correcting standing posture, posture, strengthening waist and abdominal muscles, and preventing chronic low back pain. It can also be used to eliminate excessive waist and hip fat and women's post-natal body shape recovery, which is most suitable for daily wear.

When the average weight-bearing height of the front palm is higher than the average weight-bearing height of the back end by 25-50 mm, it is suitable for the relief and treatment of patients with moderate lumbar muscle strain and has a good consolidation effect. When the average load-bearing height of the front palm is higher than the average weight-bearing height of the back end by 50 to 75 mm, it is suitable for the relief and treatment of patients with severe chronic low back pain, and can play a certain traction treatment effect, but standing or walking needs some assistance and has the best Effect of treatment.

The shoes of the present invention have a front-to-back and low-to-back situation. In addition to the average load-bearing height, the shoe can also be expressed with the backward inclination of the sole. The former varies with the size of the shoe, and the same average load-bearing height difference will have a different situation, so The backward incline angle can be used to express the accurate situation of the shoe more clearly. The sole should be tilted backwards between 2 and 7 degrees. It can be used for the relief and treatment of patients with chronic low back pain. It also has the health effects of correcting standing, walking, strengthening waist and abdomen muscles, and preventing chronic low back pain. The backward tilt of the sole is preferably between 2.5 and 6 degrees, which is most suitable for everyday wear.

The function of the present invention is: when the wearer stands on the horizontal ground, the soles of the feet are higher than the heels, forcing the center of gravity of the human body to move backward. Feet are the foundation of human standing and walking, and the basis of human mechanics. All the activities of the foot can only take effect through the transformation of the sole. The shape of the sole directly affects the transformation of the force and can determine the transformation method to a certain extent. For example, when wearing high heels and flat shoes, people's gait is quite different. Human mechanics is an organic whole. Human gait determines the movement of the human body and directly affects the posture of the human body. If you maintain a certain posture for a long time, a fixed posture will be formed. Poor posture will inevitably lead to bad posture, and waist and leg pain and cervical spondylosis are the consequences of poor posture. The poor posture of the person excessively moves the center of gravity of the human body forward, causing the pelvis to lean forward and the spine Vertebral curvature, lumbar lordosis, unbalanced stress on the articular surface of the lumbar vertebra, causing damage to the cartilage of the joint and accelerating its degenerative process. Lumbar muscle strain and other diseases will inevitably occur over time.

From the perspective of the structure of the soles and heels, the heels are more suitable for bearing weight than the soles. Prolonged load bearing of the soles of the feet will cause damage to the muscles and ligaments. The transverse arch structure of the soles of the feet cannot be maintained. Eventually, the transverse arch collapses and the forefoot becomes flat. The heel does not have the above problem. There is a huge calcaneal tubercle under the calcaneus, which is the most suitable part for bearing weight.

From the perspective of the entire human being, the reason why humans can walk normally depends on the function of the heel. Standing and walking with the heel are the concrete manifestations and characteristics of human evolution. From the perspective of medical practice, the heel is a weight-bearing subject. Once damaged, the walking ability will be seriously affected or even lost, while the disability or loss of the toe and the front of the foot will have a small impact, which basically does not affect normal walking.

At present, a functional exercise for treating lumbar muscle strain and chronic low back pain that is popular in the world—backward walking. With this method, the center of gravity can be moved backward and the back can be forced to stand upright. It can be walked up to 300 meters per day for 3 months. Low back pain will be significantly reduced, and the structure of the moving organs will be changed during the tissue repair process, so it can bring certain curative effects, and the effect is better than other exercise therapies. Both the present invention and the backward walking have the common feature of adjusting the posture of the lower back by controlling the center of gravity of the body, but the present invention has more advantages than this, and the effect is also better and more stable. It is specifically manifested in: (1) that Exercise more safely without falling due to unclear road conditions; (2) You don't need to look back often, and your body can relax effectively. (3) Being able to exercise frequently does not require special time, nor does it need to find a better road. (4) The effect is more stable. Walking backwards can only temporarily and partially relax and exercise the waist, and cannot play a corrective role. Once in the standing or walking forward state, the original abnormal posture is restored, and the effect is difficult to maintain. Because the original abnormal posture was not formed during backward walking, the backward and forward movement mechanisms are completely different. The present invention exercises on the basis of correction, focusing on correction, correcting first and then consolidating. Correction and consolidation are performed at the same time, and there is no difference from daily life. The effect of correcting posture is much more stable. (5) Faster results. After wearing high palm shoes for a little adaptation, the neck and waist will have a clear sense of relaxation and comfort. With the gradual increase in the amount of exercise, the effect will soon be realized, and the ideal relief and treatment effect will gradually be achieved.

The medical community generally believes that the fundamental way to treat chronic low back pain is to correct poor standing and walking postures. Once a bad posture is formed, it is difficult to overcome and change it through its own efforts. This is the essence of chronic low back pain that is difficult to cure. For this reason, they must apply external forces in a targeted manner to urge them to change the compulsory correction. The present invention aims at this, and adjusts fundamentally, improves the spine state through the human body's own adjustment function, has the function of effectively alleviating and treating chronic low back pain, and prevents and protects health, and can correct the bad posture formed in life and labor. . The waist muscles contract and relax rhythmically during walking, which can improve the blood circulation of the waist and help improve the metabolism of the waist tissue. When the muscle strength and ligament strength of the waist are restored and strengthened, the stability of the lumbar spine will It is greatly improved, and the curative effect is not easy to relapse.

In the following, the function of the present invention will be described from the relationship between the support surface of the human body and the balance ability of the human body. In general, the balance of the human body is inversely proportional to the support surface when standing or walking, and the two are opposite to each other and complement each other. The worse the ability to balance, the weaker the body's ability to adjust its own balance, the larger the support surface required, and the more the foot's forces are dispersed; on the contrary, the stronger the balance ability, the smaller the support surface, and the more concentrated the foot's force. The most natural and labor-saving way for a person to stand on a smaller support surface is to keep his body as straight as possible. The smaller support surface can overcome and limit a variety of abnormal standing and walking postures, so that the lumbosacral angle will Reduced, the joint surface stress of the spine joints tends to be balanced, which makes it less strained and plays a role in protecting the spine. When walking, the smaller support surface can promote the function of the cerebellum that is responsible for the human body's balance, forcing the muscle groups around the spine to participate in the adjustment of the body's dynamic balance, to better maintain the normal state of the spine, while ensuring the correct posture of the spine, Related muscle groups have also been exercised to balance It is effectively improved and the spine morphology is corrected. If the support surface is continuously reduced, the balance ability of the person will be improved, and the spine shape will gradually become normal, forming a virtuous circle. The invention can effectively control the supporting surface of the human body, the higher the forefoot, the greater the load on the heel, the more concentrated the force, and the smaller the actual supporting surface, the more obvious the function of forcing the balance of muscles around the spine, and when the cervical and lumbar spine muscles are sufficient After being strong, the correct standing and walking postures will be formed and maintained. The muscle groups around the spine will also be forced to participate in adjusting the balance, and will become active and naturally adjust the balance. From the inevitable kingdom to the free kingdom.

Since the invention can tighten the muscles of the waist and abdomen and the buttocks, so that it can obtain effective exercise and exercise, after a certain period of use, it can reduce the fat of the abdomen and buttocks to achieve weight loss, and also help women to recover their body shape after delivery. Excessive abdominal fat and women's pregnancy are also one of the factors that cause abnormal waist conditions and chronic back pain. They and the occurrence of waist disorders are sometimes caused by each other. The abnormal condition of the waist will become a condition for fat accumulation, which will be gradually eliminated. Conditions can achieve the purpose of improving body shape, the effect is stable without rebound, and there is no need to control diet. Due to long-term bad habits, some adolescents have incorrect spine postures and need to be corrected. The products of the present invention can achieve the purpose well, and there is no discomfort and inconvenience in the correction process, which is better than existing back posture correction products. Due to the short formation time of this abnormal posture, the progress and effect of correction are more obvious than those of chronic low back pain.

Compared with the existing footwear products, the present invention has the following advantages: (1) radically eliminate the cause of the spinal curvature. Because the average load-bearing height of the forefoot is higher than the average load-bearing height of the rear end, the sole of the wearer is higher than the heel when standing and walking, and the center of gravity is forced to move backward, so that the gluteal muscles are in a moderate tension state, and the forward tilt of the pelvis is effectively controlled. It can even make the pelvis upright or lean back. The pelvis is the base of the spine. By reducing the forward leaning of the pelvis, it can correct the bad standing and posture of excessive forward leaning, so that the spine naturally straightens. Strains can relieve and treat patients with lumbar muscle strain, and have health care effects. (2) The long-term effect is good. People get corrected when they wear it, and they are consolidated and tempered when they walk. Relief, correction, treatment, and consolidation proceed simultaneously, with stable results and no relapse. (3) Breaking through the technology bias of the footwear industry.

—A kind of fitness shoes, the average load-bearing height of the forefoot is 1-75 mm higher than the average load-bearing height of the rear end, and the average load-bearing height of the forefoot and / or the rear outer side is less than the average load-bearing height of the inner side by 1-30 mm.

Similar to the situation where the front and back are low, in addition to the average load bearing angle, it can also be expressed by the inclination angle. The former varies with the size of the shoes, and the same average load height difference will be different. The inclination angle is used to represent the accurate situation of the shoe.

The forefoot and reduced rear inclination should be between 2 and 7 degrees, which can effectively affect the posture of the foot. There are fat pads on the soles of the feet and the bottom of the heel, and the fat pads on the heels are particularly thick. The slight inward tilt of the rear end of the sole has little effect on the calcaneus. It cannot change the tilt of the heel and it is impossible to correct the O-shape. The role of the legs.

The inclination of the forefoot and the reduced rear end is preferably between 2.5 and 5 degrees, which can prevent and correct O-legs without causing discomfort and has no effect on normal standing and walking.

The sole of a person's foot, especially the outside of the foot, is relatively soft, and the inclination of the sole will have a smaller effect on the heel than the heel, so in general, the forefoot inclination should be greater than the rear inclination.

The inclination of the forefoot and the rear end of the fitness shoes in the foregoing form may be the same or different according to actual conditions. When the degree of tilt is the same, it is suitable for normal people with relatively healthy feet. When the forefoot is tilted inward more than the back end, it is suitable for people with heel problems. When the forefoot is tilted inward smaller than the back end, it is suitable for people with foot problems.

When raising the forefoot, the forefoot and / or the rear side of the back should be appropriately raised, which is necessary for remission and treatment. Means. That is, the load-bearing height of the sole and / or the back of the sole gradually decreases from the outside to the inside, and the load-bearing surface of the forefoot is inclined from the outside to the inside, so that when the wearer stands on a horizontal ground, the lower surface of the outside of the forefoot (the fifth toe position) Above the lower surface of the inner side (the first toe is the position of the thumb), the rear end can also be made into the above-mentioned form, so that the upper surface of the sole is in the trend of front high back low, outer high inner low. Forcing the human body to focus on the inner and rear ends of the feet when standing or walking, so that the center of gravity of the human body falls between the two feet when standing and walking, which is beneficial to the equal distribution of human body weight between the legs and the left and right sides of the waist The force is balanced as much as possible to avoid strain on one side due to excessive load, which can effectively prevent the poor state of the muscles of the neck and waist caused by lame feet and unbalanced forces on the legs. This is important because the muscle groups on both sides of the lumbar spine in most patients with chronic low back pain are in an unbalanced state, and the back and lateral sides of the heel are very stressed. It can be clearly seen from the wear of the soles that most people ’s heels, The posterolateral wear is most severe. If the outside of the forefoot (or rear end) is not raised, it will not only achieve the desired effect but will exacerbate the left and right imbalance. For example, the abnormal walking posture of the large outer figure will damage the ankle joint. In the past, it will even form a 0-shaped leg. The result is more serious damage to the waist.

The advantages of making the load-bearing part of the sole into a high outside and a low inside position are very prominent. (A) ^^ tend to avoid harm. If the above design is not available, people with high-back and low-back soles and o-legs will be more dangerous to wear. This danger may be greater than its positive effect. A design that is too large will not be accepted. The load-bearing part is high outside and low inside, that is to say, the design of the sole inclined from the outside to the inside can avoid the above situation. (2) O-legs can be corrected. The biggest difference between people with o-legs and ordinary people is the load-bearing of the outside of the foot. Most o-legs are habitual. If the outside of the shoe is raised, the sole is inclined from the outside to the inside, and the load-bearing part of the foot will move inward, thereby changing With the weight-bearing method of the o-shaped leg, after long-term use, after the habit is formed, the o-shaped leg will be corrected. (3) Ability to correct scoliosis. The high-back and low-back soles can control the forward tilt of the pelvis, but cannot control the tilt of the pelvis in the left-right direction. If the legs of the person are o-shaped, the results are likely to produce unequal legs. Tilt the pelvis and cause scoliosis. If o-legs are corrected, scoliosis will also be fundamentally improved and corrected. (4) The forces on the legs and feet can be made more even. Many people have inconsistent load on their legs, one of which is o-shaped, so that the load is not balanced, which will eventually cause the pelvis to tilt. The tilt of the sole from the outside to the inside can change this situation and make the forces on the legs more uniform. . (5) The stress on the feet can be made more concentrated, the load-bearing surface of the person can be further reduced, the exercise of the human body's balance ability will be strengthened, and the correction of the bad posture will be more obvious. (6) Strengthened the control of the body's center of gravity in the left and right directions, and enhanced the body's ability to maintain balance.

A fitness shoe with an average weight-bearing height of the forefoot that is 1-75 mm higher than the average weight-bearing height of the rear end, and an average weight-bearing height of the outer side of the forefoot and / or the rear end is higher than the average weight-bearing height of the inner side by 1-30 mm, and thereafter The average load-bearing thickness at the end is higher than the average load-bearing thickness of the hind palm by 1 to 15 mm.

When the average load-bearing thickness of the back end is higher than the average load-bearing thickness of the back palm by 1-3 mm, it is suitable for various sports shoes, casual shoes and heelless shoes.

When the average load-bearing thickness of the rear end is higher than the average load-bearing thickness of the back palm by 3 to 8 mm, it is suitable for various shoes with a lower heel.

When the average load-bearing thickness of the back end is higher than the average load-bearing thickness of the back palm by 8-15 mm, it is suitable for all kinds of shoes with medium-height heels.

In the existing footwear products, the heel is relatively large, and it is unnecessary to raise both the rear end and the back of the palm. This is not necessary, because the back of the palm is generally not load-bearing. The waste of a material will also increase the weight of the shoe and the burden on the foot without any benefit. In some cases, it is still very harmful. If the material of the sole is not good or the sole is excessively worn, the thickness of the rear end will be reduced, so that the originally unbearable rear palm part will also be Began to bear weight. The damage to the arch of the foot by the heel load of the shoe is serious. In this state, instead of bearing the lower end of the arch, the weight at the lower end should be transferred to the inside and back of the arch. This change has fundamentally changed the mechanical state of the arch. When the two ends of the arch are on the ground, the arch is subjected to a kind of elastic pressure, and the arch is subjected to a force on the inside and the back, and the arch is subjected to an outward top force, which directly makes the arch longer. Becomes lower, its destructive force is far greater than the state where the two lower ends are stressed. According to the above hazards, it is necessary to make the average load-bearing thickness of the rear end of the sole higher than the average load-bearing thickness of the sole, and the sole may have no heel or a slightly lower heel. This can avoid damage to the arch of the foot, can also reduce the weight of the shoe, and reduce manufacturing costs. The transition between the rear end portion of the sole and other parts of the sole may be a continuous transition or an intermittent transition.

All the above-mentioned fitness shoes have at least two raised structures on the forefoot and / or rear end portion of the outsole. This raised structure is similar to the studs of sneakers or running shoes. It can be made of metal or rubber, plastic or rubber and plastic. The shape of the raised structure is not limited, and may be cylindrical, square cylindrical, prismatic, conical, square pyramidal, or pyramidal. The raised structure may be integrated with the outsole of the shoe or may be mounted together. The diameter and height of the spikes can be selected according to different types. The sole with such a raised structure can greatly reduce the weight of the sole, is very comfortable to wear, and can also reduce manufacturing costs. When the forefoot has this structure alone, the structure is similar to that of running shoes, which is not only lightweight, but also suitable for sports, and is convenient for active and adolescents to use. The plane formed by the lowermost ends of three or more raised structures may be parallel to the insole or may have a certain angle. When the plane is parallel to the insole plane, it is particularly suitable for running.

The raised structure described above is movably mounted. The installation method can imitate the structure of football boots. When the present invention is used for the treatment and correction of body posture, as the correction proceeds, the relative heights of the front and rear and the relative heights of the inner and outer sides of the sole are frequently adjusted. This raised movable installation structure can be installed on the forefoot and / or the rear end. A pair of shoes can be equipped with a plurality of raised structures of different heights. Each adjustment and replacement of the studs is equivalent to changing a kind of shoes. It is economical and affordable, and can be used for multiple purposes. It is especially suitable for posture correction and shaping. This structure is best installed on the forefoot, which can make the shoe lighter.

In the sole of the fitness shoe of the present invention, the forefoot and / or the rear end of the outsole are provided with thick objects that are movably mounted. This thickened object can be any solid material with a certain thickness, preferably rubber or plastic products. The movable installation method can adopt slot, bayonet structure, buckle structure such as dragon buckle (tooth fur), and nut and bolt structure. The purpose is the same as the raised structure of the movable installation, but it is more stable than the raised structure, and is particularly suitable for installation at the rear end of the sole.

In the sole of the fitness shoe of the present invention, the insole and / or midsole is movably mounted. The outsole or the part above the outsole is not fixed, that is, the insole and midsole are not bonded, stitched and stapled, so that the outsole or outsole and the upper form a shoe cavity, the insole or midsole It can be easily replaced. The relative height of the midsole and the insole is different, and the condition of the sole is different. A pair of shoes can be equipped with multiple insoles and midsoles of different heights and postures.

The insole and midsole can be replaced as a whole or partly. Replacing the load-bearing parts, namely the forefoot and the rear end, can effectively adjust the relative height of the sole before and after. By replacing the inside and outside of the forefoot and / or the back, you can adjust the relative height of the inside and outside and tilt inward. For the sake of convenience, only the rear end of the sole can be replaced. The front-rear height of the sole and the inside and outside tilt of the sole can be adjusted at any time. Therefore, it is also possible to make only the back-end part as a structure for active installation. The movable installation of the insole and the outsole can play the same role as the movable installed studs. The adjustment is more convenient, but the range of change is slightly smaller.

The rear end of the sole of the fitness shoe of the present invention is solid. In footwear products, there is generally some space at the rear end of the sole in order to reduce weight. In the solution of the present invention, since the stress of the sole is concentrated on the heel, a hollow one is used. The heel is not suitable. It is best to choose a solid body to prevent the heel from deforming.

Sole can be mounted on the sole. For shoes with a large difference in height between the forefoot and the back end, a hook should be installed, which can strengthen the connection between the forefoot and the back end, so that the shoe becomes a whole, and the burden on the foot is lighter during use. The sole can also be mounted without a hook. For shoes with a small difference in height between the forefoot and the back end, it is not necessary to install a hook. Such soles are easier to bend, which is convenient for sports and long-distance walking.

In the fitness shoes of the present invention, the sole height and posture of the left and right shoes of the same pair of shoes may be different. A pair of shoes with different leaning postures has a special correction function. Some people have very different forces on their left and right feet or the overall length of their legs is inconsistent. This requires correction in this regard. The method is to raise the forefoot or rear end of the shoe on the side where the force is greater, so that The height of the other shoe, when standing or walking, the load on the side with a larger height naturally decreases, which plays a role of artificially adjusting the balance. It is suitable for the relief and treatment of patients with severe chronic low back pain and scoliosis. Good treatment effect can also make up for some physiological defects.

In order to wear more comfortably, the technical solutions of Chinese patents 94110290.4 and 96225238.7 can be adopted. Raise the midsole of the shoe so that there is a small amount of space between the midsole and the outsole. There are vent holes on both sides to exclude sweat and turbid gas. The gas outlet is more than 5 mm from the ground. Made of impervious material. The midsole can also be divided into two parts, the lower part is made of materials that are not easily permeable to water, and the upper part is made of materials that are highly absorbent, so that the lower layer is waterproof and the upper layer absorbs sweat, so that the feet can stay dry for a long time. The role of sweat.

In order to better play the role of health care, the soles can be equipped with magnets, infrared emitting devices or medicines, and can be installed and placed at the acupoints of the soles of the feet. The medicines can be made into smaller medicine packs, or the midsole can be directly absorbed for easy use. There may also be some small, raised particles on the upper surface of the sole to massage the feet. These particles can be molded with the sole at one time, or they can be installed after the sole is molded.

In order to protect the crossbow of the foot, the forefoot can also have an upwardly protruding arc shape, so that the crossbow will not completely disappear when the foot is stressed, which can effectively avoid damage to the crossbow.
