{SOLES OF SHOES} A shoe sole having a shock-

The present invention relates to a shoe sole, and more particularly, to a shoe sole having a height of a forefoot of a soles of shoes is higher than a height of a heel, and a cushion layer for absorbing shocks to mitigate heel impact, Shoe soles.

In general, shoes are indispensable necessities in everyday life. There are dozens of kinds of shoes, and they are divided into sneakers, shoes, slippers, basketball shoes, soccer shoes, and hiking shoes according to their functions and functions.

In recent years, as a result of interest in exercise, shoes have been recently produced and sold in a variety of designs to provide a variety of functions or to complete the fashion, and to take advantage of the style and personality of the wearer. Choose footwear to threaten foot health.

Among the various diseases associated with foot disease, plantar fasciitis and arthralgia are the most common. Plantar fasciitis has greatly increased in recent 5 years, and in 2014, 176,868 patients were treated. The treatment was concentrated from July to October It is presumed that the number of people who are aware of the symptoms with increasing outdoor activity is also increasing.

Although it is known that the hallux valgus is mainly caused by women wearing high heels, the number of male patients has also increased sharply due to the increase in Yummy, which means young urban men who are interested in fashion and appearance recently. The National Health Insurance Corporation According to an analysis of the number of patients with hallux valgus for 10 years from 2005, the number of female patients increased from 23,000 in 2005 to 55,000 in 2014, while the number of male patients increased from 3,200 in 2005 to 8,800 in 2014 2.7 times.

Plantar fasciitis is a disease of the plantar fascia, a muscle that absorbs shocks that are transmitted to the soles of the foot by wearing too hard or inappropriate shoes.

In recent years, as interest in health has increased, there are 959 travel routes nationwide including diverse roads, olegil, and old road along with "walking fever", which are currently being supported by national and local governments. The number of patients is increasing as the number of people enjoying exercise through life increases.

Particularly, plantar fasciitis is prone to be caused by wearing flat shoes that are not even 1cm in height, which is applied to the heel of the paddle with the ground due to weight.

If left untreated for a long time, the plantar fasciitis may be limited to daily life with chronic heel pain. If the walking habit changes due to pain, it may cause pain in the forefoot, knee, hip, and back.

The hallux valgus is prone to develop when the hoop is too high or too low, such as high heels, plan shoes, sneakers, etc., when the football is narrower than the foot shape,

The foot movements on the ground during walking are largely composed of three steps: the landing phase by the heel, the center shift from the heel to the forefoot, and the forefoot pushing away from the ground.

During such walking, the landing impact caused by the load including the weight of the wearer is transmitted to the heel during the landing stage, and when the forefoot pushes the ground, the force that pushes the load including the weight of the wearer to the forefoot As a result, there is a problem that it causes pain caused by walking to a patient suffering from foot related diseases such as plantar fasciitis and hallux valgus.

Conventional shoes have been made to have a higher heel height than the heel so as to alleviate the impact on the heel, but this has limitations in reducing the pain of patients suffering from foot related diseases.

The floor window 110 is composed of a bottom portion 112 in the form of a shoe soles and a curved portion 114 formed to extend upward from the rear of the bottom portion 112.

The floor window (110) is landed on the heel when walking, and the center of gravity moves from the heel to the forefoot so that the forefoot portion is in direct contact with the ground in a walking process that pushes away the ground.

The bottom portion 112 is in contact with the ground in a process of moving the center of gravity from the heel to the forefoot portion and pushing the forefoot portion away from the ground, and the curved portion 114 is formed in a manner that the center of gravity moves from the heel to the forefoot Lt; / RTI >

The bottom portion 112 and the curved portion 114 of the bottom window 110 are provided in the lowest layer and the middle window 120 provided at the upper portion of the bottom window 110, The window 130 and the upper window 140 are prevented from being in direct contact with the ground, thereby preventing the window 130 and the upper window 140 from being worn.

Therefore, it is preferable that the bottom window 110 is made of a material which is excellent in abrasion resistance and is slid so as not to slip when the ground is slippery.

Further, it is preferable that an emboss preventing slip is formed on the lower surface 116 of the bottom window 100 which is in contact with the ground.

The first middle window 122 is provided on the upper surface of the bottom window 110 and has the same shape as the bottom portion 112 of the bottom window 110 and one side of the rear portion of the heel is wrapped around the curved portion 114.

Preferably, the first midsole 122 is made of an elastic hard material having excellent elastic repulsive force so as to absorb a part of the impact transmitted to the wearer's foot when walking.

The cushion window 130 is provided between the middle windows 120 and absorbs impact applied to the feet during walking. The cushion window 130 has the same shape as the bottom portion 112 of the bottom window 110, 114).

The cushion window 130 primarily absorbs the landing impact transmitted to the feet during walking, and the cushion window 130 is compressed in the landing stage where the greatest impact is applied, and the weight is moved and restored to its original state Relieves the impact on the foot.

Therefore, it is preferable that the cushion window 130 is made of a flexible elastic soft material having excellent elastic repulsive force.

Since the entire thickness of the cushion window 130 is constant, it is difficult to maintain the shape of the cushion window 130 alone. Therefore, the cushion window 130 is preferably provided between the first and second middle windows 122 and 124 to maintain the shape of the shoe sole.

The second middle window 124 is provided on the upper surface of the cushion window 130 and has the same shape as the bottom portion 112 of the bottom window 110 and one side of the rear portion of the heel is wrapped around the curved portion 114.

It is preferable that the second middle 124 is an elastic hard material having excellent elastic repulsive force so as to absorb a part of the impact transmitted to the feet of the wearer during walking, and to maintain the shape.

The upper portion 140 of the shoe sole 100 is provided on the upper surface of the second middle portion 124.

The upper portion 140 is formed with an inclined portion 142 whose height decreases toward the rear of the forefoot in front of the forefoot portion and the inclined portion 142 is lowered toward the rear to be curved with one side of the upper surface of the heel of the middle 120, But is not in contact with the curved portion 114 of the bottom window 110.
