The separation structure of

Referring to Figures 1 to 9, first of the sports running shoe of the present invention is formed in the lower portion of the bottom material consisting of insoles, midsoles and outsoles are rounded in an arc shape in the longitudinal direction, from the shoe inner diameter to the outer diameter in the width direction It is formed to be inclined upward at an angle.

To this end, in the present invention, the lower portion is formed in a shape rounded in the longitudinal direction, and in the width direction in the form of a diagonal of the shoe inner portion 41 to the outer portion 43, that is, in a diagonal form of 3 to 7 degrees upward from the shoe inner diameter to the outer diameter. Midsole body 11 is formed to be inclined and the acupressure protrusions 16 are respectively formed in the upper portion and the central portion.

Specifically, the lower portion of the midsole body 11 of the flooring material is formed round in an arc shape in the longitudinal direction, and the bottom surface is formed in a diagonal form 3 to 7 ° upward from the inner side to the outer side, and all of the upper portion of the midsole body 11 And acupressure protrusions 16 are respectively formed in the center portion, and the outsole 30 having a constant thickness having a round shape matching with the lower surface of the midsole body 11 is attached and formed so that the lower portion is rounded in the longitudinal direction as a whole. It is formed so as to form a flooring material inclined in the form of 3 to 7 degrees upward diagonally from the shoe inner part 41 to the outer part 43.

If the inclination in the width direction of the bottom of the bottom including the midsole 10 and the outsole 30 of such a structure is less than 3 ° in the center of the foot starting from the center of the heel substantially when walking wearing sports running shoes including the bottom, Since landing on the ground in the order of five toes, the effect of inducing a correct walking posture is reduced, and when the inclination in the width direction of the bottom of the floor exceeds 7 °, the ankle joint of the wearer when walking wearing sports running shoes including the flooring Doing so can cause joint damage.

The acupressure projections are respectively formed on the upper and center portions of the upper and middle portions of the midsole body 11, which are formed to be inclined upwardly in a diagonal shape from 3 to 7 degrees from the inner side of the shoe to the outer side in the width direction so as to round the lower portion in an arc shape as described above. 16) is formed. The acupressure protrusions 16 formed on the upper and middle portions of the midsole body 11 respectively stimulate the acupressure points of the sole and the center of the sole of the shoe wearer to reduce fatigue due to walking.

Specifically, the acupressure protrusions 16 of the upper part of the midsole body 11 stimulate the yongcheon blood, the point where the nerve starts at the front of the foot of the shoe wearer to clear the mind, lower the blood pressure, insomnia, hypertension, myocardial system diseases It is configured to facilitate the prophylactic treatment, the acupressure projections 16 in the upper central portion of the midsole body 11 is configured to stimulate blood vessels, which are the major acupressure points in the center of the shoe wearer's foot, to prevent blood flow disorders of the feet and cerebral. .

And a seating portion (not shown) is formed on the big toe portion, the outer diameter front and the outer diameter rear of the upper surface of the midsole body 11 and the buffer pads (13a, 13b, 13c) of the flexible foam polyurethane, respectively In addition, a buffer member 19 inserting portion (not shown) is formed at the rear center portion of the midsole body 11 to insert and seat the buffer material 19 of a gel material.

However, in order to protect the foot of a shoe wearer and to promote walking smoothly, rather than having a buffer pad of a single structure formed in the outer diameter part of the upper surface of the midsole main body 11 of the upper surface of the midsole main body 11, It is preferable that buffer pads 13a, 13b, and 13c each having separate structures are formed at the big toe part, the outer diameter front, and the outer diameter rear, respectively.

That is, each of the buffer pads 13a, 13b, and 13c is individually seated on each of the seating portions (not shown) of the big toe portion of the upper surface of the midsole body 11, the front of the outer diameter, and the rear of the outer diameter. In order to form the midsole body 11, the toe portion of the upper surface, the seating portion of the outer diameter front and the outer diameter rear portion must be shaped to match the respective buffer pads 13a, 13b, 13c.

Among the buffer pads 13a, 13b and 13c of the flexible foamed polyurethane material separately formed as described above, the buffer pad 13a of the big toe portion of the upper portion of the midsole body 11 is applied to the big toe portion. The absorption pad 13b of the outer diameter front effectively absorbs and absorbs the shock applied to the outer diameter front portion of the foot, and the shock absorbing pad 13c of the outer diameter rear effectively absorbs and absorbs the shock applied to the rear portion of the outer diameter of the foot. This is to protect the wearer's feet as a whole.

In addition, the midsole of the sports running shoe of the present invention includes a support plate made of duralumin material or fiber-reinforced plastic material formed on the upper rear portion of the buffer pad.

In general, when the shoe is used for a long time, a phenomenon in which the shape of the midsole 10 of the bottom of the shoe is deformed due to the impact continuously applied from the ground in the landing stage occurs. Therefore, in order to maintain the shape of the midsole 10 of the flooring material while at the same time to hold the shape of the foot of the sports running shoe wearer, the support plate 17 of a predetermined size is formed in the midsole body 11, in the present invention The midsole 10 of the flooring material of a sports running shoe is comprised using the support plate 17 of the material chosen from the group which consists of a duralumin material or a fiber-reinforced plastic material which is small in specific gravity and excellent in durability, strength, and elasticity resilience.

As a material of the support plate 17 formed in the upper rear part of the midsole body 11, a general synthetic resin or a metal other than duralumin may be used, but the general synthetic resin support plate 17 is very poor in durability and strength, and the midsole The function of maintaining the shape of the (10) is greatly reduced, the support plate 17 made of a metal other than duralumin material lacks the elastic force to increase the impact applied to the foot of the shoe wearer and maintain the shape of the midsole 10 Not only is it insufficient to function, but it is also not suitable for use as a shoe material due to its high specific gravity. Accordingly, the midsole 10 of the flooring material of sports running shoes using a support plate 17 having a thickness of 2 to 3 mm made of duralamine or fiber-reinforced plastic, which has a low specific gravity and is excellent in durability and strength and excellent in elastic restoring force.
