Definitions
- the present invention relates to a shoe sole and a shoe having the same, and more particularly, to a shoe sole for losing weight and a shoe having the same, which can simultaneously provide a kinetic effect to the same extent as a wearer lifts dumbbells with the legs and a correction of knee joint deformities.
- gait of a human being is divided into a stance phase and a swing phase.
- the stance phase means the instant the foot contacts the ground, and accounts for approximately 60 percent of a normal gait cycle.
- the stance phase is subdivided into five phases: initial contact, loading response, midstance, terminal stance, and preswing.
- the Initial contact represents the beginning of the stance phase, and occurs the instant the heel of the foot touches the ground first.
- the hip joint is bent, the knee joint is straightened, and ankle joint moves the top of the foot a little upward (dorsiflexion).
- the opposite foot is in the terminal stance phase. That is, it means a simultaneous stance phase.
- Loading response which is the second phase of the stance phase, occurs directly after the heel of the foot touches the ground.
- the foot comes in full contact with the floor, and body weight is transferred onto the stance limb.
- the knee joint is bent a little in order to absorb impact to the transferred weight, so that the body weight does not transferred excessively.
- the ankle joint moves down the foot (plantarflexion) and the opposite foot is in the preswing phase.
- Mid stance which is the third phase of the stance phase, occurs when the center of gravity of the body goes over the center of the sole of the foot. During this phase, the body weight is supported by only one foot, and the hip joint is straightened. In this instance, the ankle joint moves the top of the foot upward (dorsiflexion), and the opposite foot is in a midswing phase of the swing phase.
- Terminal stance which is the fourth phase of the stance phase, occurs when the hip joint and the knee joint are gradually straightened and the ankle joint carries out the movement to gradually move down the top of the foot to thereby prevent that the center of gravity of the body is excessively transferred to the front.
- the opposite foot is in a terminal swing phase of the swing phase and prepares for the initial contact phase.
- Preswing which is the fifth phase of the stance phase, occurs when the contralateral foot contacts the ground and ends with ipsilateral toe off. In this instance, the hip joint and the knee joint are gradually bent, and the ankle joint carries out the plantarflexion. The opposite foot is in the loading response phase.
- the swing phase means the period that the foot leaves the ground, and accounts for approximately 40 percent of a normal gait cycle.
- the swing phase is subdivided into three phases: initial swing, mid swing, and terminal swing.
- the initial swing phase occurs after toe-off, and in this instance, a swing speed gradually increases through a motion that the foot swings in the air, and the hip joint and the knee joint carries out flexion. Additionally, the ankle joint carries out dorsiflexion, and the opposite foot is an early stage of the mid stance phase.
- Mid swing which is the second phase of the swing phase, is the final stage of the initial swing and the early stage of the terminal swing.
- the hip joint and the knee joint are gradually straightened while going through the central line of the body.
- the ankle joint keeps the dorsiflexion state of the mid swing phase, and the opposite foot is in the final stage of the mid stance.
- Terminal swing which is the final phase of the swing phase, is a phase that the knee fully extends in preparation for heel contact.
- the hip joint keeps a slightly bent state but the knee joint is fully straightened, and the ankle joint keeps the dorsiflexion state.
- the opposite foot is in the terminal stance phase.
- a human being walks while moving the center of body weight forward by moving weight of a part of his or her body forward.
- the shoes have a problem in that they do not provide a posture correction effect because they have been invented to induce the bouncy gait by concentrating body weight on the toe portion of the foot in order to provide a marathon race effect or a run race effect even while walking.
- the conventional shoes have another problem in that they do little to lose weight due to a poor kinetic effect.
- the present invention has been made to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a shoe sole for losing weight and a shoe having the same, which can simultaneously provide a kinetic effect to the same extent as a wearer lifts dumbbells with the legs and a correction of knee joint deformities.
- a shoe sole for losing weight comprising: a shoe sole having a joining recess formed on an upper face or a lower face thereof; and a joining member having a form corresponding to the form of the joining recess and joined to the joining recess, the joining member being made of a material, which is higher in density than that of the shoe sole.
- the joining member has a front portion heavier than a rear portion.
- the joining recess is formed at a toe area of the shoe sole.
- the joining recess is formed on an inner side of the shoe sole for a wearer with O-shaped legs.
- joining recess is formed on an outer side of the shoe sole for a wearer with X-shaped legs.
- the plural joining recesses are respectively formed at the toe area and the central area in a longitudinal direction of the shoe sole, and at least one of the joining recess of the toe area and the joining recess of the central area has an inclined surface.
- the joining recess formed at the toe area of the shoe sole is formed within a range of 0% to 40% in a forward longitudinal direction of the shoe sole, and the joining recess formed at the central area of the shoe sole is formed within a range of 41% to 80% in the forward longitudinal direction of the shoe sole.
- the inclined surface of the joining recess is an upward inclination, which is inclined upwardly from the inner side of the shoe sole.
- the inclined surface of the joining recess is a downward inclination, which is inclined downwardly from the inner side of the shoe sole.
- the joining recess is formed on the upper face of the shoe sole, an insole is disposed on the shoe sole, and the joining member and the insole are formed integrally with each other.
- the joining recess is formed on a lower face of a midsole of the shoe sole, and the joining member is formed integrally with an upper face of an outsole of the shoe sole.
- the shoe sole further includes a groove formed on a side of the bottom surface of a rearfoot portion of the shoe sole in order to reduce weight of the rearfoot portion.
- the above object can be achieved by a shoe having the shoe sole for losing weight, which is described above.
- the shoe having the shoe sole for losing weight can provide the wearer with the kinetic effect to the same extent as a wearer lifts dumbbells with the legs because the forefoot portion is heavier than the rearfoot portion, whereby it helps to lose weight.
- the present invention can increase a kinetic effect by making plantarflexion quicker and smoother during a limb support because the center of gravity of the shoe sole is transferred forward.
- the present invention can control the inside and outside balance of load applied to the foot and the knee because the central point of the ground reaction force moves toward the center of the foot and it shows an ideal trajectory of the central point of the ground reaction force, so that the O-shaped legs or the X-shaped legs can be corrected into the straight legs.

Abstract
Description
- 1. Field of the Invention
- The present invention relates to a shoe sole and a shoe having the same, and more particularly, to a shoe sole for losing weight and a shoe having the same, which can simultaneously provide a kinetic effect to the same extent as a wearer lifts dumbbells with the legs and a correction of knee joint deformities.
- 2. Background Art
- In general, gait of a human being is divided into a stance phase and a swing phase. The stance phase means the instant the foot contacts the ground, and accounts for approximately 60 percent of a normal gait cycle. The stance phase is subdivided into five phases: initial contact, loading response, midstance, terminal stance, and preswing.
- Here, the Initial contact represents the beginning of the stance phase, and occurs the instant the heel of the foot touches the ground first. In this instance, the hip joint is bent, the knee joint is straightened, and ankle joint moves the top of the foot a little upward (dorsiflexion). Furthermore, the opposite foot is in the terminal stance phase. That is, it means a simultaneous stance phase.
- Loading response, which is the second phase of the stance phase, occurs directly after the heel of the foot touches the ground. During loading response, the foot comes in full contact with the floor, and body weight is transferred onto the stance limb. The knee joint is bent a little in order to absorb impact to the transferred weight, so that the body weight does not transferred excessively. At the same time, the ankle joint moves down the foot (plantarflexion) and the opposite foot is in the preswing phase.
- Mid stance, which is the third phase of the stance phase, occurs when the center of gravity of the body goes over the center of the sole of the foot. During this phase, the body weight is supported by only one foot, and the hip joint is straightened. In this instance, the ankle joint moves the top of the foot upward (dorsiflexion), and the opposite foot is in a midswing phase of the swing phase.
- Terminal stance, which is the fourth phase of the stance phase, occurs when the hip joint and the knee joint are gradually straightened and the ankle joint carries out the movement to gradually move down the top of the foot to thereby prevent that the center of gravity of the body is excessively transferred to the front. In this instance, the opposite foot is in a terminal swing phase of the swing phase and prepares for the initial contact phase.
- Preswing, which is the fifth phase of the stance phase, occurs when the contralateral foot contacts the ground and ends with ipsilateral toe off. In this instance, the hip joint and the knee joint are gradually bent, and the ankle joint carries out the plantarflexion. The opposite foot is in the loading response phase.
- The swing phase means the period that the foot leaves the ground, and accounts for approximately 40 percent of a normal gait cycle. The swing phase is subdivided into three phases: initial swing, mid swing, and terminal swing. Here, the initial swing phase occurs after toe-off, and in this instance, a swing speed gradually increases through a motion that the foot swings in the air, and the hip joint and the knee joint carries out flexion. Additionally, the ankle joint carries out dorsiflexion, and the opposite foot is an early stage of the mid stance phase.
- Mid swing, which is the second phase of the swing phase, is the final stage of the initial swing and the early stage of the terminal swing. The hip joint and the knee joint are gradually straightened while going through the central line of the body. In this instance, the ankle joint keeps the dorsiflexion state of the mid swing phase, and the opposite foot is in the final stage of the mid stance.
- Terminal swing, which is the final phase of the swing phase, is a phase that the knee fully extends in preparation for heel contact. In this instance, the hip joint keeps a slightly bent state but the knee joint is fully straightened, and the ankle joint keeps the dorsiflexion state. The opposite foot is in the terminal stance phase.
- Walking starts as the center of body weight is transferred forward. A human being walks while moving the center of body weight forward by moving weight of a part of his or her body forward.
- It is the most idealistic to lift up the leg and straighten up the upper body when weight of a part of the body is put forward for walking. However, persons with a rapid pace or persons with weak muscle strength at the lower limbs put their heads forward. When the head is put forward, the back is naturally bent to thereby cause musculoskeletal disorders. Such a symptom increases while the wearer wears high-heeled shoes. The reason is that the high-heeled shoes cause an instable posture due to a forward movement of the center of gravity. In this instance, the upper body is bent forward and the hips are pulled back in order to prevent that the wearer falls forward due to the forward bending of the upper body. Accordingly, the human body has two centers of the upper body and the lower body: one being a hip joint-centered line; and the other being a spine-centered line. Then, impact to the waist grows up and it may cause backache.
- As the level of income has increased with the development of industries, the basic food, clothing and shelter problems have been solved, but health-related problems, such as stress, adult diseases, obesity, and so on, have become serious social problems. In the meantime, recently, the whole nation is growing more and more interested in health due to the advent of the well-being era. In such a context, exercise, orthotherapy, diet, and so on has recently become the main interest among not only women but also men. With the trend of society, heelless shoes for losing weight have been invented. When a wearer wears the heelless shoes, because the center of the foot naturally moves toward to the tiptoe and the wearer walks in a bouncy gait, power is concentrated on the abdomen and the legs and muscles of the calves and the femoral muscle are repeatedly relaxed, whereby it improves muscular strength and endurance to thereby provide a weight loss effect.
- However, the shoes have a problem in that they do not provide a posture correction effect because they have been invented to induce the bouncy gait by concentrating body weight on the toe portion of the foot in order to provide a marathon race effect or a run race effect even while walking. Moreover, the conventional shoes have another problem in that they do little to lose weight due to a poor kinetic effect.
- Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a shoe sole for losing weight and a shoe having the same, which can simultaneously provide a kinetic effect to the same extent as a wearer lifts dumbbells with the legs and a correction of knee joint deformities.
- To accomplish the above object, according to the present invention, there is provided a shoe sole for losing weight comprising: a shoe sole having a joining recess formed on an upper face or a lower face thereof; and a joining member having a form corresponding to the form of the joining recess and joined to the joining recess, the joining member being made of a material, which is higher in density than that of the shoe sole.
- In this instance, the joining member has a front portion heavier than a rear portion.
- Furthermore, the joining recess is formed at a toe area of the shoe sole.
- Moreover, the joining recess is formed on an inner side of the shoe sole for a wearer with O-shaped legs.
- Additionally, the joining recess is formed on an outer side of the shoe sole for a wearer with X-shaped legs.
- In addition, a plurality of the joining recesses is formed.
- Furthermore, the plural joining recesses are respectively formed at the toe area and the central area in a longitudinal direction of the shoe sole, and at least one of the joining recess of the toe area and the joining recess of the central area has an inclined surface.
- Additionally, the joining recess formed at the toe area of the shoe sole is formed within a range of 0% to 40% in a forward longitudinal direction of the shoe sole, and the joining recess formed at the central area of the shoe sole is formed within a range of 41% to 80% in the forward longitudinal direction of the shoe sole.
- Moreover, the inclined surface of the joining recess is an upward inclination, which is inclined upwardly from the inner side of the shoe sole.
- In addition, the inclined surface of the joining recess is a downward inclination, which is inclined downwardly from the inner side of the shoe sole.
- Furthermore, the joining recess is formed on the upper face of the shoe sole, an insole is disposed on the shoe sole, and the joining member and the insole are formed integrally with each other.
- Additionally, the joining recess is formed on a lower face of a midsole of the shoe sole, and the joining member is formed integrally with an upper face of an outsole of the shoe sole.
- Moreover, the shoe sole further includes a groove formed on a side of the bottom surface of a rearfoot portion of the shoe sole in order to reduce weight of the rearfoot portion.
- In another aspect of the present invention, the above object can be achieved by a shoe having the shoe sole for losing weight, which is described above.
- According to the present invention, the shoe having the shoe sole for losing weight can provide the wearer with the kinetic effect to the same extent as a wearer lifts dumbbells with the legs because the forefoot portion is heavier than the rearfoot portion, whereby it helps to lose weight.
- Furthermore, the present invention can increase a kinetic effect by making plantarflexion quicker and smoother during a limb support because the center of gravity of the shoe sole is transferred forward.
- Moreover, by controlling the position of the joining member, the present invention can control the inside and outside balance of load applied to the foot and the knee because the central point of the ground reaction force moves toward the center of the foot and it shows an ideal trajectory of the central point of the ground reaction force, so that the O-shaped legs or the X-shaped legs can be corrected into the straight legs.
