Description

Sole of Masai walking shoes {A sole of Masai Walking shoes}

The present invention relates to a sole of a masai walking shoe, and more specifically, a waist shank is embedded in a professional shoe midsole for a masai walking and a front and rear shank is built in an insole, so that the movement of the foot on the ground during walking is a landing step and a center moving step. In the case of the three-time walking divided into two stages and the breakaway stage, the three-time rolling movement, which is operated by the elasticity of the double shank, occurs smoothly and presses the shank during walking. It relates to the sole of the through tunnel of the shoe.

The present invention relates to a sole structure of professional shoes for masa walking that can reproduce the masai walking, and in the Korean Patent No. 10-377822, the name of the reference numeral 1: shoes, 2: upper, 3: shoe sole, 10: insole (insole: insole), 12: midsole, 13: outsole, and Korean Patent No. 10-377822 shows that there is no heel of the shoe and that the sole of the shoe is curved like a Masai, the sole of which is curved. Masai Walking Specialized rolling walking shoes (active rolling walking shoes) is called a walking method as shown in Figures 2 to 4 of the Korean Patent No. 10-377822, "Masai Walking (Masai Walking) 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 TV broadcasts are referred to as Masai Walking or Masai Walking Specialized Shoes, Masai Walking Specialized Shoes, Masai Walking Patent Shoes or Masai Walking Patent 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.

Conventional massaging walking shoes midsole has a high elastic shank built-in, such a shank is built into the upper rear side, and the front part is divided into several parts by forming a plurality of slits open to the front end at a certain position of the front. In the central waist portion, bead-shaped ribs for reinforcement are formed in the front-rear direction. The shank embedded in the conventional midsole walking shoes midsole has a problem that the midsole itself does not fall smoothly when walking three beats, and the three beats walking is unnatural due to the feeling of splashing midsole itself.

The present invention is to improve the problems appearing in the above-described conventional shoes, as the sole structure of the professional shoes for Masai walking that can reproduce the Masai walking, the waist shank is built in the midsole and the front and rear shank is built in the insole when walking In the case of a three-time walking where the foot movement is divided into landing, centering, and disengagement phases, the three-beat rolling movement, which is activated by the elasticity of the double shank, occurs smoothly, The purpose of the present invention is to provide a sole for mounting a rolling shoe for masai walking, which can cause an arching pressure effect.

The present invention has a built-in spring shank in which the front shank and the back shank is combined with one or several springs in a professional shoe midsole for masa walking.

According to the present invention, the waist shank is embedded in the midsole, and the front and rear shanks are embedded in the insole, and the bottom of the heel of the sole is formed in a curved shape in the front and rear direction according to the shape of the heel and the motion trajectory of the heel relative to the ankle joint during walking. Three-time rolling movement that is operated by elasticity of double shank when three-time walking is divided into landing stage, center movement stage and departure stage. It is very useful in the shoe industry because it can produce a professional shoe for masai walking that can make the arch effect acupressure because it presses the shank and the shank when walking smoothly.

The present invention is made of any one selected from polyester and polyurethane having a hardness of 40 to 60 in the sole of the masai walking shoe that can reproduce the masai walking consisting of upper, insole, insole, midsole and convex curved outsole. A plurality of through tunnels 22 are formed in the shape of a convex curved shape from the front part to the rear part, the inclination angle of the heel is 25 to 45 degrees, and penetrated from one side of the rear part to the other side. A midsole 20 formed integrally with a plurality of upper protrusions 24 and lower protrusions 26 integrally formed with the midsole between the through tunnels 22; A waist shank (29) embedded in a waist portion corresponding to a rear portion at a central portion of the upper portion of the midsole (20), and having slits and ribs formed therein; An insole 10 mounted on an upper portion of the midsole 20 and composed of a nonwoven fabric having a hardness of 25 to 30, and having a front and rear shank 29-1 having slit and rib formed therein; It is mounted on the lower part of the midsole 20, made of any one selected from polyester and polyurethane with a hardness of 70 to 80, is formed in the arc shape of the curved surface convex from the front to the rear, the inclination angle of the heel It relates to a sole of a masai walking shoe, characterized in that consisting of an outsole 30 formed to be 25 to 45 degrees.

Masai walking shoes of the present invention is a normal shoe composed of upper, outsole and insole and the sole of the shoe consists of insole 10, midsole 20 and outsole 30, there is no heel of the shoe and the sole bottom of the shoe is curved Masai Barefoot Technology shoes, Masai walking shoes, Masai walking shoes, Masai walking shoes, Masai walking patents, Masai walking patents It's about shoes.

In the shoe of the present invention, the midsole 20 is formed in the shape of a plate, modeling the shape of the sole and the surface of the sole, and the waist shank (29) inside the waist portion extending from the upper center portion to the rear portion of the midsole 20. Since the bottom of the heel of the sole is formed in a curved shape in the front and rear direction according to the shape of the heel and the motion trajectory of the heel relative to the ankle joint during walking, a rolling motion is performed with respect to the ground during walking.

The waist shank 29 and the front and rear shank 29-1 built in the insole are the landing phase, the center movement step, and the separation step of the foot during walking. In the case of three-time walking, which is divided into two, elasticity is doubled and rolling is naturally performed due to elasticity of the double shank. In addition, the waist shank (29) and the front and rear shank (29-1), which is built in the insole and the masai walking shoe midsole 20 of the present invention is elastic in walking from the heel to the heel without the feeling of splashing shoe sole when walking. In this form, the roll occurs naturally. In addition, the waist shank (29) and the front and rear shank (29-1), which is built in the insole is the landing step, the center movement step and In the case of three-time walking divided into two stages, the three-time rolling movement, which is operated by the double elasticity, occurs smoothly, and the double-shank is pressed during walking, which can cause the arch-type acupressure effect.

Midsole 20 in the masai walking shoe of the present invention is formed in the form of a plate modeled after the outer shape and curved shape of the sole and the waist shank (shank) (29) from the upper back portion to the rear portion of the midsole 20 Is built-in, the front and rear shank (29-1) is built from the inner front of the insole to the rear portion is the two shanks are supported on the ground during walking while the synergistic action and the rolling movement is made. The waist shank 29 embedded in the midsole of the present invention is formed with one or a plurality of slits 29a. The slit allows the molding liquid to flow smoothly during the production of the midsole, and when the fluid is solidified, the shank itself is firmly fixed and supported within the midsole. The slit is divided into slits in which a plurality of slits with open ends are formed or closed are preferably selected according to the viscosity of the fluid. The shank is formed with one or a plurality of ribs (29b) to prevent the shank itself is bent to strengthen the strength of the shank, it is preferable to form a through hole with a small slit size to strengthen the adhesive strength. .

In the shoe of the present invention, the midsole 20 has a waist shank 29 inserted therein, and the front and rear shanks 29-1 are embedded in the insole, which preserves the sole of the sole and the shoe and flexes during walking. The sole with high frequency of deformation is restored smoothly to its original shape, and it improves the stability of walking when walking and adds a repulsive force during the step of departure to promote light walking. In the shoe of the present invention, the shank may be formed in any shape and material, but it is preferable to form the shape of the plate by shaping the shape of the midsole and insole and the shape of the surface using synthetic resin (PVC) material, and the bending angle is relatively high when walking. The large shank forms a number of slits that open to the front end at a certain position in the front and divides into several equal parts to facilitate the bending of the anterior gingiva area, and the center waist of the shank is bead-shaped rib for reinforcement. (29b) is formed in the front and rear direction so that the molding liquid can be smoothly flow during the production of the midsole (20).

In the shoe of the present invention, the rear axle of the outsole 30 is formed in an arc of an inclined curved shape having a main inclination angle of 25 to 45 degrees of the shoe squeeze to the ground, and when the main inclination angle is 25 degrees or less, the rolling action of the professional shoe for masai walking If this is not done and the main inclination angle is 45 degrees or more, the inclination may be too steep, resulting in an unstable and unstable posture when wearing shoes or standing.

In the shoe of the present invention, the midsole 20 is made of any one selected from polyester and polyurethane having a hardness of 40 to 60. If the hardness of the midsole is 40 or less, the softness of the midsole does not serve as a support and the hardness of the midsole is not sufficient. If it is more than 60 there is a problem that the midsole does not act as an elastic body so hard.

In the shoe of the present invention, the midsole 20 has a plurality of through tunnels 22 formed integrally with the midsole at a rear portion thereof, and a plurality of upper protrusions 24 and lower protrusions 26 between the through tunnels 22. ) Is integrally formed with the midsole, and integral tunnels and protrusions are formed in the front portion of the midsole, which are integrally formed with the midsole, thereby shortening the manufacturing process and reducing the manufacturing cost of the midsole. In the shoe of the present invention, a plurality of through tunnels 22 are integrally formed with the midsole at the rear portion, and a plurality of upper protrusions 24 and lower protrusions 26 are disposed at the rear portion between the through tunnels 22. It is formed integrally with the midsole, and integral tunnels and protrusions are formed integrally with the midsole, thereby preventing the soft sensor from being damaged by hydrolysis and generating strong repulsion by the cushion.
