DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0044] Hereinafter, example embodiments will be described in detail with reference to the accompanying drawings so that inventive concept may be readily implemented by those skilled in the art. However, it is to be noted that the present disclosure is not limited to the example embodiments but can be realized in various other ways.

[0045] In the drawings, certain parts not directly relevant to the description are omitted to enhance the clarity of the drawings, and like reference numerals denote like parts throughout the whole document.

[0046] Throughout the whole specification, unless explicitly stated to the contrary, the word comprise, comprises or comprising used throughout the specification will not be understood as the exclusion of the other elements but to imply the inclusion of the other elements.

[0047] First, a bottom part 30 of a corrective insole 10 according to a first preferred embodiment of the present invention has a skinned part 80 formed from the calcaneus to the head of the fifth metatarsal bone so that the weight of a human body can be easily transferred to the most lateral side 90 and can be scattered along the most lateral side 90.

[0048] Here, the bottom part 30 of the corrective insole 10 includes a posterior molded part 60 formed at the position corresponding to the calcaneus, and an anterior height part 50 formed at the position corresponding to the head of the fifth metatarsal bone.

[0049] Here, the skinned part 80 having a boundary protrusion part 70 is formed between the posterior molded part 60 and the anterior height part 50.

[0050] Moreover, the skinned part 80 makes weight shifted to the outside to scatter the weight along the most lateral side 90 of the corrective insole.

[0051] Furthermore, a difference in height between the tip (a) and the heel (b) is made such that 60% to 80& of the weight of the body is scattered to the heel and 20% to 40% is scattered to the tip while the line of gravity passes between the calcaneus and the cuboid bone.

[0052] Here, if a person wears shoes having the corrective insoles of which the difference in height between the tip (a) and the heel (b) is 1 cm to 3 cm, because the tip (a) is slightly higher than the heel (b), it makes the center of gravity located between the calcaneus and the cuboid bone when the wearer stands up.

[0053] In the meantime, the bottom part 30 of the corrective insole 10 includes a plurality of protrusions 40 at the front side thereof for prevention of slipperiness, so that the insole does not slip inside the shoe.

[0054] Additionally, the corrective insole includes an arch part 100 rising on a surface part 20 so as to give a stimulus to a flat foot and to prevent a normal foot becomes a flat foot.

[0055] Now, actions of the corrective insole according to the present invention will be described as follows.

[0056] First, FIG. 1 is a view showing the structure of bones of the foot.

[0057] Here, the sole of a human body consists of two important arches: one being a lateral plantar arch for supporting the weight of the body; and the other being a medial plantar arch functioning as a spring during an exercise.

[0058] The lateral plantar arch includes the calcaneus which is the heel, the cuboid bone which is the most lateral of the bones, and the fifth metatarsal.

[0059] The medial plantar arch includes the calcaneus, the talus, the navicular, the cuneiform which is an arch part, and the first metatarsal bone.

[0060] However, the feet of the human body become flat feet due to exercises on a hard ground, sudden exercises, lack of flexibility in crural muscles, and so on.

[0061] In the meantime, because weight does not move to the lateral plantar arch while the weight moves from the outside to the inside in an arch form, load of the medial plantar arch cumulates, hence the arch form of the medial plantar arch is collapsed and the feet become flat feet.

[0062] FIG. 2 is a perspective view showing a base side of a corrective insole according to a first preferred embodiment of the present invention.

[0063] Here, a bottom part 30 of the corrective insole 10 includes a posterior molded part 60 formed at the position corresponding to the calcaneus, an anterior height part 50 formed at the position corresponding to the head of the fifth metatarsal bone, and a skinned part 80 having a boundary protrusion part 70 formed between the posterior molded part 60 and the anterior height part 50.

[0064] Here, there is little difference in height between the tip (a) and the heel (b) or the tip (a) is slightly higher than the heel (b).

[0065] The corrective insole 10 of the present invention may be made through pressing or injection-molding using a mold.

[0066] FIG. 3 is a front view showing the base side of the corrective insole according to the first preferred embodiment of the present invention

[0067] Here, the skinned part 80 makes weight shifted to the outside to scatter the weight along the most lateral side 90 of the corrective insole.

[0068] Furthermore, because there is little difference in height between the tip (a) and the heel (b) or the tip (a) is slightly higher than the heel (b), the skinned part 80 is made such that 60% to 80& of the weight of the body is scattered to the heel and 20% to 40% is scattered to the tip while the line of gravity passes between the calcaneus and the cuboid bone.

[0069] FIG. 4 is a schematic perspective view showing a used state of the corrective insole according to the first preferred embodiment of the present invention.

[0070] Here, if a person wears shoes (not shown) having the corrective insoles 10, the skinned part 80 makes the weight shifted onto the outside so as to scatter the weight along the most lateral side 90 of the corrective insole.

[0071] Moreover, if a person wears shoes (not shown) having the corrective insoles of which the difference in height between the tip (a) and the heel (b) is 1 cm to 3 cm, because the tip (a) is slightly higher than the heel (b), it makes the center of gravity located between the calcaneus and the cuboid bone when the wearer stands up.

[0072] FIG. 5 is a perspective view showing a base side of a corrective insole according to a second preferred embodiment of the present invention.

[0073] Here, a bottom part 30 of the corrective insole 10 includes a posterior molded part 60 formed at the position corresponding to the calcaneus, an anterior height part 50 formed at the position corresponding to the head of the fifth metatarsal bone, and a skinned part 80 having a boundary protrusion part 70 formed between the posterior molded part 60 and the anterior height part 50.

[0074] The corrective insole 10 according to the present invention may be made through injection-molding using a mold.

[0075] FIG. 6 is a front view showing the base side of the corrective insole according to the second preferred embodiment of the present invention.

[0076] Here, the skinned part 80 makes weight shifted to the outside to scatter the weight along the most lateral side 90 of the corrective insole.

[0077] FIG. 7 is a schematic perspective view showing a used state of the corrective insole according to the second preferred embodiment of the present invention.

[0078] Furthermore, because there is little difference in height between the tip (a) and the heel (b) or the tip (a) is slightly higher than the heel (b), the skinned part 80 is made such that 60% to 80& of the weight of the body is scattered to the heel and 20% to 40% is scattered to the tip while the line of gravity passes between the calcaneus and the cuboid bone.

[0079] Here, the bottom part 30 of the corrective insole 10 includes a plurality of protrusions 40 at the front side thereof for prevention of slipperiness.

[0080] FIG. 8 is a perspective view showing a used state of the corrective insole of the present invention.

[0081] Here, a bottom part 30 of a corrective insole 10 according to a first preferred embodiment of the present invention has a skinned part 80 formed from the calcaneus to the head of the fifth metatarsal bone so that the weight of a human body can be easily transferred to the most lateral side 90 and can be scattered along the most lateral side 90.

[0082] In addition, the corrective insole includes an arch part 100 rising on a surface part 20 so as to give a stimulus to a flat foot and to prevent a normal foot becomes a flat foot.

[0083] In the meantime, in this specification, the corrective insole 10 which is configured as the lowermost component of a shoe is described, but if necessary, the present invention is applicable not only to an outsole but also to a midsole.

[0084] Moreover, of course, the corrective insole 10 is made of a buffering material with excellent strength and hardness.

[0085] FIG. 9 is a front view showing a difference in height of the tip and the heel of the corrective insole according to the present invention.

[0086] As described above, the corrective insole according to the present invention makes a load by weight of the body and a load by an exercise shifted on the heel of the foot when the wearer stands up, and receives a load transferred from the calcaneus which is the heel of the foot and transfers the received load to the cuboid bone which is the most lateral of the bones of the foot, so as to optimally scatter the loads transferred to the foot.

[0087] Therefore, the corrective insole according to the present invention can prevent foot diseases and pronation, such as knock-kneed legs or bowed legs, and makes the load of the knee transferred from the anterior cartilage to the posterior cartilage through correction so that the pelvis, the back and the neck are straightened naturally.

[0088] The above description of the present disclosure is just for illustration, and a person skilled in the art will understand that the present disclosure can be easily modified in different ways without changing essential techniques or features of the present disclosure. Therefore, the above embodiments should be understood as being descriptive, not limitative.
