[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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 (SiO.sub.2), 26% feldspar (Al.sub.2O.sub.3), 1% biotite (Fe.sub.2O.sub.3), 2% garnet (CaO), 0.5% apatite (MgO), 2.58% calcite (NaddO), 13% chlorite (TiO.sub.2), 2% sericite (P.sub.2O.sub.5), 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/cm.sup.2, an elastic wave velocity of 4.685 m/sec, and shore hardness of 83, and besides, the lapillus performs far-infrared radiation.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.
