The present invention relates to an airbag and a midsole for mounting a specialized walking shoe with a built-in upper and lower tunnel parts. An airbag and an upper and lower tunnel part are formed on an upper pad and a polyurethane support protrusion is formed on an upper pad and a lower pad. It is possible to easily and simply manufacture the midsole for mounting the rolling shoes, and to prevent the polyurethane support protrusions mounted inside from being damaged by hydrolysis, thus preserving the original shape of the sole and shoes, and the frequency of bending during walking. The present invention relates to an airbag and a midsole for mounting a specialized walking shoe with a built-in upper and lower tunnel parts, which have excellent shape recovery of high soles and improve walking stability.

In Korean Patent No. 10-377822, the reference numerals are 1: shoe, 2: upper, 3: shoe sole, 10: insole, 12: midsole, and 13: outsole. Looking at Korean Patent No. 10-377822, there is no heel of the shoe and the sole of the shoe is a Masai walking shoe like the Masai. The active walking walking foorware is a well-rolled walking shoe. 2 to 4 of Korean Patent No. 10-377822 shows a walking method as described below, and is described as "walking by Masai Walking."

The Korean Walking Association, the World Walking Association, the footwear industry, and the general consumer call shoes such as Masai Barefoot Technology shoes walking like the Maasai without the heel of the shoe and the sole of the shoe's sole. Books, newspapers, magazines and television broadcasts are referred to as Masai Walking Shoes or Masai Walking Shoes.

In general, the movement of the foot on the ground during walking is a three-step process, in which the left and right feet repeat the landing step by the heel, the center moving step from the heel to the heel, and the step of the heel pushing off the ground. In conventional shoes, the shape of the heel is formed at a right angle to the ground, and in the case of shoes, a sharp edge is formed on the heel so that this edge touches the ground first during the landing stage. Because of its linear shape, the impact at the time of landing is large, and the movement to the center movement stage, which is the next stage of landing, is performed at once, so that a sudden impact force is transmitted to each joint of the leg and body as well as the ankle joint, resulting in poor landing feeling and walking. It becomes unnatural.

In the case of using a soft sensor material having a hardness of 15 to 30 in a conventional shoe sole, since the soft sensor material having a hardness of 15 to 30 is made of a soft sponge (Soft Sponge, Soft Wedge, Masai sensor), the soft sponge material is wet. Alternatively, when hydrolysis occurs in wet soil and shoes are worn in a wet place or rural paddy field, there is a problem that the sensor is separated in less than one month, and shoes made of soft sensor material having a hardness of 15 to 30 are used. Since it is a soft sponge, the water absorbed and the water absorbed sponge has a problem that the sensor is tattered off the shoe by pressing tens of thousands of times a day for more than one month continuously for a whole day with the hooves applied to the weight of 60kg to 100kg. Furthermore, if you wear a shoe made of soft sensor material with a hardness of 15 to 30, and you run a marathon or run, you can press the sponge with your heels with a weight of 100kg to 300kg and press it tens of thousands of times a day for more than a month. There was a problem that the sensor fell apart. In particular, it was presented to parents in the countryside because it was called filial piety shoes. In the case of wearing shoes made of soft sensor material with hardness of 15 to 30 in rural paddy fields, the sensor fell off in less than a month, causing repair of the shoe sole. There was a problem of performing after-service (recall).

The present invention has been made to improve the above-described problems in the conventional shoe, the air pad and the upper and lower tunnel portion is formed on the upper pad, and the polyurethane support protrusion is formed on the upper pad and the lower pad for the professional wearing of masai walking rolling shoes The midsole can be easily and simply manufactured, and the polyurethane support protrusion mounted inside can be prevented from being damaged by hydrolysis, thus preserving the original shape of the sole and shoes, and the shape of the sole with high frequency of bending during walking.
