DETAILED DESCRIPTION OF THE EMBODIMENTS

(8) Hereinafter, with reference to the accompanying drawings, embodiments of the present disclosure will be described in detail so that those of ordinary skill in the art can easily carry out the present disclosure. However, the present disclosure may be embodied in many different forms and is not limited to the embodiments described herein. In addition, in order to clearly explain the present disclosure in the drawings, portions irrelevant to the description are omitted, and similar reference numerals are attached to similar portions throughout the specification.

(9) Throughout the specification, when a portion is said to be “connected” to another portion, it includes not only a case where it is “directly connected” but also a case where it is “electrically connected” with another element interposed therebetween. In addition, when a portion “includes” a certain component, this means that other components may be further included, rather than excluding the other components, unless otherwise stated.

(10) Hereinafter, an ergonomic shoe insole according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. Meanwhile, the shoe insole will be mainly described below, but an embodiment of the present disclosure may be applied to a bottom surface of the shoe as well as the insole.

(11) FIG. 1 is a perspective view illustrating a lower surface 20 of a pair of shoe insoles 1 according to an embodiment of the present disclosure. FIG. 2 is a perspective view illustrating an upper surface 10 of the pair of shoe insoles 1 according to an embodiment of the present disclosure. FIG. 3 is a perspective view illustrating the lower surface 20 of the shoe insole 1 according to an embodiment of the present disclosure.

(12) Referring to FIGS. 1 to 3, an overall shape of the shoe insole 1 according to an embodiment of the present disclosure is that a rear portion disposed adjacent to the heel of a user has a round shape, and a front portion that is disposed adjacent to an intermediate portion of the foot of the user may have a rectangular shape with rounded corners. Accordingly, the shape of the lower surface 20 of the insole may be similar to a shape (similar to a horseshoe shape) in which a horizontal straight line is drawn on an upper portion of the letter U.

(13) FIG. 4 is a perspective view illustrating a pressure distribution portion 30 of the shoe insole 1 according to an embodiment of the present disclosure. FIG. 5 is a bottom view illustrating the pressure distribution portion 30 of the shoe insole 1 according to an embodiment of the present disclosure.

(14) Further referring to FIGS. 4 and 5, the shoe insole 1 according to an embodiment of the present disclosure may include a first polygonal groove 21, a first wall portion 22, the pressure distribution portion 30, a second polygonal groove 31, a second wall portion 32, and a third wall portion 33.

(15) The first polygonal grooves 21 may be a plurality of hexagonal grooves that are formed to be arranged in hexagonal shapes on the lower surface 20 of the insole. Five first polygonal grooves 21 may be laterally arranged side by side in the insole. The plurality of first polygonal grooves 21 may be arranged adjacent to each other on the lower surface 20 of the insole to have an overall honeycomb structure. In addition, the first polygonal groove 21 may have various shapes such as a pentagon, a heptagon, and an octagon, as well as the hexagonal shape. In addition, adjacent polygonal shapes may be the same shape, or may be different polygonal shapes.

(16) Hereinafter, the first polygonal groove 21 will be described as an example having the hexagonal shape.

(17) The first wall portion 22 may be a partition member forming a rim of the first polygonal groove 21. The plurality of first polygonal grooves 21 may be formed with one first wall portion 22 interposed therebetween. That is, the first polygonal grooves 21 may have a structure in which the first wall portion 22 is shared as one side of the hexagon.

(18) In general, when a person walks, his/her weight is concentrated on the back and the outside of his/her foot. The pressure distribution portion 30 is a portion located on the inside of the foot and the concentration of the weight of the person is directed toward the pressure distribution portion 30, so that the load is distributed over the entire foot during walking. The pressure distribution portion 30 may be disposed on a part of the lower surface 20, which is formed on the inside of the insole. For example, the pressure distribution portion 30 may be formed in an inner center portion of the lower surface 20 of the insole. Referring to FIG. 5, a portion where the heel of the foot is disposed may be the back of the insole, the opposite side may be the front, and a portion where an outer edge (edge in a direction adjacent to the little toe) of the foot is disposed may be the outside of the insole, and a portion where an inside edge (edge in a direction adjacent to the big toe) of the foot may be the inside of the insole. That is, the pressure distribution portion 30 is disposed at a position slightly moved from the center of the insole in a lateral direction corresponding to the inner edge of the foot. According to the position and structure of the pressure distribution portion, the center of gravity of the foot may be moved toward the pressure distribution portion when the user walks. Accordingly, a force may be applied to the inner portion of the foot of the user, or the center of gravity may be moved to the inner portion of the foot during walking. Although many people have poor gait, it is often quite difficult to correct the gait. As an example, in a case where the gait is incorrect and the outside of the foot mainly come into contact the ground during walking, the surface corresponding to the outside of the bottom surface of the shoe may be quickly worn. In a case of providing these people with the structure of the insole or the bottom surface of the shoe of the present disclosure, it is possible to correct the bottom surface of the shoe coming into contact with the ground, thereby correcting the gait.

(19) The second polygonal groove 31 is disposed in the pressure distribution portion 30 and may be a groove formed with a rim including the second wall portion 32 having a height lower than that of the first wall portion 22. The second polygonal groove 31 has a hexagonal shape and may be formed in the same pattern as the first polygonal groove 21. In addition, the second polygonal groove 31 may have various shapes, such as a pentagon, a heptagon, and an octagon, as well as the hexagonal shape.

(20) Hereinafter, the second polygonal groove 31 will be described as an example having the hexagonal shape.

(21) The second polygonal groove 31 may include the second wall portion 32 having the height lower than that of the first wall portion 22 to form a rim. In addition, the second polygonal groove 31 may be configured to include the third wall portion 33 that connects the first wall portion 22 and the second wall portion 32 to each other, and has an inclination decreasing from the height of the first wall portion 22 to the height of the second wall portion 32. For example, the second polygonal groove 31 may be formed by being surrounded by three first wall portions 22 and two second wall portions 32, and including the third wall portion 33 that connects the first wall portion 22 and the second wall portion 32. In addition, all six sides of the second polygonal groove 31 may be formed of the second wall portions 32.

(22) In addition, in the pressure distribution portion 30, any one of the plurality of wall portions forming the rim of the plurality of second polygonal grooves 31 is omitted so that the open-type second polygonal groove 34, which is open with another adjacent second polygonal groove 31, may be formed. For example, the second wall portion 32 blocking two second polygonal grooves 31 may be omitted to form the open-type second polygonal groove 34 having a decagonal shape. As the wall portion is omitted, the hardness of the pressure distribution portion 30 is weakened, and when the weight of the wearer of the shoe is applied to the pressure distribution portion 30, the pressure distribution portion 30 may be more flexibly deformed.

(23) In addition, the pressure distribution portion 30 may have a shape in which a number of the second polygonal grooves 31 and the open-type second polygonal grooves 34 are gathered as a whole. For example, two second polygonal grooves 31 may be disposed adjacent to each other in the center of the pressure distribution portion 30, and a plurality of the open-type second polygonal grooves 34 may be disposed adjacent to the two second polygonal grooves 31. In addition, the pressure distribution portion 30 may be formed by a combination of a total of four second polygonal grooves 31 and three open-type second polygonal grooves 34.

(24) FIG. 6 is a plan view illustrating the upper surface 10 of the shoe insole 1 according to an embodiment of the present disclosure. FIG. 7 is a side view illustrating a side surface of the shoe insole 1 according to an embodiment of the present disclosure.

(25) A heel support portion 11 may be formed on the upper surface 10 of the shoe insole 1 according to an embodiment of the present disclosure.

(26) The heel support portion 11 may be formed to protrude from a back rim of the upper surface 10 of the insole to support the heel of the foot. The heel support portion 11 may include an inclination portion 111 that is inclined downward toward the front from the back of the insole.

(27) The inclination portion 111 may be provided to mount the shoe insole 1 on the inner side of the shoe without any discomfort. In addition, an inclination degree of the inclination portion 111 may be formed to be steep toward the front from the back of the insole.

(28) The upper surface 10 of the insole may be inclined downward toward the front from the back. Accordingly, the height of the insole decreases from the back to the front of the shoe, and the front of the insole has almost no difference in height with the inner bottom of the shoe, thereby improving the fit of the shoe.

(29) As described above, the shoe insole 1 according to an embodiment of the present disclosure includes the pressure distribution portion 30 to distribute the pressure applied locally to the foot of the wearer to increase the fit of the shoe.

(30) The shoe insole 1 according to an embodiment of the present disclosure includes the plurality of first polygonal grooves 21 and second polygonal grooves 31 on the lower surface 20 to form the honeycomb structure, so that a strong and comfortable shoe insole can be provided.
