The present invention relates to a shoe including an insole with lapillus attached thereto and a foot deformity correction outsole that is configured to allow the insole inserted thereinto to have an upper plate with protruding surfaces therefrom at given intervals and to allow the lapillus to be attached to the position of the insole corresponding to the acupressure point “Yongcheonhyeol” of the foot sole, thereby applying acupressure for a wearer's foot to help his or her blood circulation, and configured to allow the outsole to have different elastic forces according to plane positions thereof, thereby preventing obstacles in keeping the wearer's health from occurring due to his or her body weight inclination by leg deformities such as bowlegs, knock knees, and the like and further achieving leg deformity correction.
When a person walks, a pressure applied to his or her feet is three times his or her body weight, and when runs, a pressure is seven times his or her body weight. In specific, a load up to 400 tons a day is applied to the feet, and accordingly, the feet support the body and serve as a body balancer. Further, the feet provide a force needed for walking and lift blood up to the heart, and in view of oriental medicine, the feet is considered as a microcosm of the body, to which energy of the internal organs of the body is collected. In specific, “Yongcheonhyeol”, which means it lifts spring water up, is only one acupressure point on the foot sole. The acupressure point “Yongcheonhyeol” is located on the foot sole, but it is widely used to treat diseases of the head or brain.
In the case of a person having bowlegs or knock knees, further, a distance between the knees is relatively long or short so that a load larger than a normal load is transferred to the insides or outsides of the knees, thereby causing the knee joints to be damaged. Such load is transferred even to the shoes to cause given portions of the outsoles of the shoes to be worn out, and accordingly, leg deformity correction studies have been made through the change in the shape of the insole.
As the feet move continuously, they are difficult to be easily dried from water such as sweat, and through the wet feet, accordingly, bad odor is generated from the feet and the interiors of the shoes. Further, bacteria are produced from keratin of the stratum corneum of the foot sole and undesirably grow in the feet and shoes.
Accordingly, shoes or insoles capable of applying acupressure to the foot sole and gently moving internal sweat and air through the insides thereof have been developed, and one of the conventional insoles is disclosed in Korean Patent No. 10-1857154 (Issued on May 11, 2018) that relates to a bio insole for acupressure for “Yongcheonhyeol” and a method for manufacturing same, the bio insole including a base sheet 110 for covering the bottom surface of a shoe, and a fabric sheet 120 attached to top of the base sheet 110, wherein the base sheet 110 includes a protrusion portion 130 protruding upwardly from a position corresponding to the acupressure point “Yongcheonhyeol” and having an accommodation space 135 open downward therefrom and a buffering blower 150 accommodatedly attached to the accommodation space 135. Further, one of the conventional acupressure insoles is disclosed in Korean Utility Model Application No. 20-2012-0001076 (Issued on Feb. 15, 2012) that relates to an acupressure insole including: an insole; and an attachment plate attached to top of the insole and having acupressure protrusions with acupressure protruding portions protruding upwardly from the center thereof to apply acupressure for a given portion of the foot sole, the number of acupressure protrusions is seven.

If necessary, the explanation will be given with reference to embodiments and drawings. Further, the terms as will be discussed later are defined in accordance with the functions of the present invention, but may be varied under the intention or regulation of a user or operator. Therefore, they should be defined on the basis of the whole scope of the present invention.
According to one aspect of the present invention, as shown, the shoe according to the present invention includes: an insole 10 having an upper plate 12 disposed on top thereof to come into contact with a wearer's sole and a lower plate 18 attached to the underside of the upper plate 12 to support the upper plate 12 thereagainst; and an outsole 20 whose underside coming into contact with the ground, while seating allowing the insole 10 onto top thereof, having a region of a front portion where a foot ball is located larger than that of a rear portion where a foot heel is located when viewed on the plane, and allowing a given position of the front portion, onto which a big toe is seated, to protrude forwardly by a given length from a given position of the front portion, onto which a little toe is seated.
The upper plate 12 has a plurality of flat protruding surfaces and a plurality of tripod-shaped protruding surfaces protruding from top thereof, and the flat protruding surfaces are provided on the foot heel and a portion corresponding to an acupressure point “Yongcheonhyeol” on the foot, while the tripod-shaped protruding surfaces are being provided on the remaining portions of the foot.
Further, a plurality of pieces of lapillus 30 is attached to the protruding surface from the portion of the upper plate 12 corresponding to the acupressure point “Yongcheonhyeol” to perform acupressure for the acupressure point “Yongcheonhyeol” of the foot sole.
The lower plate 18 is made of neoprene foam rubber having the same shape as the upper plate 12 on the plane, and top of the lower plate 18 is fixedly attached to the underside of the upper plate 12.
General shoes sold on the market are configured to allow the centers of the front portions of the insole and the outsole to protrude more forwardly than the remaining portions of the front portions, but according to the present invention, when viewed on the plane, the outsole 20 is configured to allow a region onto which the foot ball is seated to be relatively large and to allow a given position of the end of the front portion thereof, onto which a big toe is seated, to protrude more forwardly by a given length than a given position of the end of the front portion thereof, onto which a little toe is seated, so that the outsole 20 has the same shape as the foot of the human body, thereby providing high wearing comfort for the wearer. Accordingly, the curve on the shape of the outsole in the inward direction of the foot is more reduced than that of the general shoe, and further, the shape of the insole 10 on the plane is the same as of the outsole 20.
The lapillus 30 used in the present invention is Yeoungyang lapillus as a conglomerate that is produced from Nugun fault of Gyeongsang basin of Mesozoic era at a depth of 100 meters from the ground surface of the mountain Ilwol and consists of sedimentary rocks, volcanic rocks, granitic rocks, metamorphic rocks, limestone, and the like, and through the analysis of physical and chemical properties of the lapillus 30, the lapillus 30 contains 25% quartz (SiO2), 26% feldspar (Al2O3), 1% biotite (Fe2O3), 2% garnet (CaO), 0.5% apatite (MgO), 2.58% calcite (NaddO), 13% chlorite (TiO2), 2% sericite (P2O5), and 0.05% other minerals (MnO). As the result of the test for physical properties of the lapillus, further, the lapillus has a specific gravity of 2.63, an absorption rate of 0.254%, a porosity rate of 0.74%, a compressive strength of 1.11 kg/cm2, an elastic wave velocity of 4.685 m/sec, and shore hardness of 83, and besides, the lapillus performs far-infrared radiation.
The “Yongcheonhyeol”, which is a concave portion in the middle of the foot sole, is an acupressure point in the oriental medicine that is a well point in meridians located in the middle of the foot sole, through which qi energy flows. If the best acupressure point on the foot, “Yongcheonhyeol” is used in case of an emergency, it opens a blocked blood hole to help mental health stabilized.
The upper plate 12 of the insole 10 is made of a synthetic resin or rubber and has a plurality of fine through holes (not shown) formed thereon, through which air flows to the inside of the shoe.
Further, each flat protruding surface has a height of 1 to 3 mm from the top of the upper plate 12, each tripod-shaped protruding surface has a height of 6 to 8 mm therefrom, and each piece of lapillus 30 has a height of 2 to 3 mm therefrom (In this case, the height of the lapillus 30 attached to the flat protruding surface is greater or less than the height of each tripod-shaped protruding surface by a given height so as to minimize the pain of the foot sole caused by the lapillus 30). However, their height may be set as desired by a wearer or a manufacturer.
Accordingly, the heights of the flat protruding surfaces, the tripod-shaped protruding surfaces, and the lapillus 30 are adjusted through the selection of the wearer, thereby reducing the pain caused by the acupressure obtained from the flat protruding surfaces, the tripod-shaped protruding surfaces, and the lapillus 30.
Further, a fabric material 16 is attached to top of the upper plate 12 to provide water absorption and ventilation, and the fabric material 16 is one selected from a fabric and leather and has through holes formed correspondingly to the lapillus 30 to pass the lapillus 30 therethrough.
The lower plate 18 is used as neoprene foam rubber and may be replaced with silicone or rubber foam. Accordingly, the lower plate 18 has a given elastic force and allows the air applied from the upper plate 12 to pass therethrough.
The lower plate 18 has a lattice or honeycomb structure capable of gently moving air inside the shoe and reducing degrees of impacts applied to the foot, such as an impact generated by the wearer's body weight, an impact caused by the acupressure, and the like, while the wearer is walking or running.
The outsole 20 is made of one or more materials selected from leather, rubber, urethane, synthetic polymer, and jute, and when viewed on the plane, the outsole 20 is divided into six regions corresponding to the forefoot, midfoot, hindfoot, left side foot, right side foot, and the like. Next, each of the six regions is divided into three sub-regions, and accordingly, some of the divided regions are selected according to body weight inclination of the wearer due to his or her bowlegs or knock knees. Further, the elastic force of the material for the selected regions is relatively lower than that for the regions not selected.
In the case of the bowlegs, in specific, the wearer's load is collected to the outer side of the foot, and accordingly, the material for the regions located on the outer side of the outsole has relatively high strength. In the case of the knock knees, contrarily, the wearer's load is collected to the inner side of the foot, and accordingly, the material for the regions located on the inner side of the outsole has relatively high strength. In the case where the wearer's load is collected to the front or back side of the body according to his or her body characteristics, some of the 18 regions, which are selected according to his or her body characteristics, are made of a material with relatively high strength, thereby enabling his or her weight center to be positioned at the center of his or her body.
The tripod-shaped protruding surfaces of the upper plate 12 of the insole 10 may be replaced with flat or semicircular protruding surfaces.
A foot deformity corrector 14 is detachably coupled to the region on which toes are located on the upper plate 12 with the flat protruding surfaces, and the foot deformity corrector 14 has a flat surface and a horizontal plate. The horizontal plate has a protrusion located between the big toe and the second toe.
Further, the horizontal plate of the foot deformity corrector 14 may have the shape of the tripod-shaped protruding surface or the semicircular protruding surface of the upper plate 12 according to the protruding surfaces of the upper plate 12.
The foot deformity corrector 14 as well as the shape of the outsole 20 serves to protect the wearer from hallux valgus that is a foot deformity in which a toe bone is inclined outward from a first metatarsophalangeal joint of the big toe and a heel bone is inclined inward.
The outsole 20 is separated from the insole 10, but the outsole 20 may be formed integrally with one or both of the upper plate 12 and the lower plate 18 on top thereof. In specific, the upper plate 12 or both of the upper plate 12 and the lower plate 18 of the insole 10 may be provided on top of the outsole 20.
According to another aspect of the present invention, a super-absorbent resin 40 is disposed between the fiber material 16 and the upper plate 12 and is made of powder obtained by drying and pulverizing bio cellulose produced from bacteria and edible seagrasses.
In specific, the super-absorbent resin 40 is made through a method including the steps of agitating bio cellulose of fine fiber in the form of power, which is produced from bacteria, and the powder obtained by drying and pulverizing rhodophyta, edible seagrasses with heated pulverized water; dissolving the agitated mixture with potassium chloride (KCl), cooling the dissolved mixture at a room temperature to a state of a gel, injecting the gel into a pulverizer, together with ethanol to pulverize the gel, agitating the pulverized gel with ethanol additionally injected, and dewatering and drying the agitated gel.
