(13) First, made of synthetic resins such as urethane, the insole(10) is equipped with columns(13), which are embedded with a plurality of springs(11), injection molded on the bottom, and massaging protrusions(15) which are protruded on the upper side of the columns(13). Here, as shown in FIGS. 2 and 3, it is desirable that the columns(13) and massaging protrusions(15) of the insole(10) are arranged in positions of pancreas and stomach in plantar reflex among forefoot, rearfoot, and arches; first air holes(17) are formed in the center for discharging compressed air when compressing springs(11); and second air holes(19) are formed at the side of the columns(13) and massaging protrusions(15) for discharging compressed air when compressing insoles(10). Further, it is desirable to make the springs'(11) stiffness of forefoot and rearfoot different each other, i.e., setting the forefoot, less stiff, and the rearfoot, stiffer, thereby making the springs(11) roll smoothy while walking; and to reinforce the rearfoot which gets more weight.

(14) Further, made of synthetic resins such as urethane, the sole(20) comprises a space(21) for fixing the insole(10) on the top, and a plurality of insertion grooves(23) for inserting the columns(11) to the bottom of the space(21).

(15) Further, formed as the same shape of the sole with any one of materials such as plastic, rubber and metal, for having elastic restoring force upon deformation, the deformation prevention frame(30) is injection molded with the sole(20) and attached to the side edge. Here, it is desirable that the deformation prevention frame(30) is equipped with a plurality of penetrating holes(31) for being combined to urethane, inserted inside, when injection molded with the sole(20), and may be colored differently as compared to the sole(20), thereby making highly colored. Further, colors of the deformation prevention frame(30) may be set up differently in accordance with types of patients of diabetes and high blood pressure so that patients may select depending on his disease's type; and upon emergency, ambulance workers or doctors may administer first aid by easily checking diabetes and high blood pressure of patients, i.e., indicating red, Type I diabetes, blue, Type II diabetes, and yellow, both diabetes and high blood pressure.

(16) Further, made of shock absorbing materials such as blowing urethane foam or blowing sponge foam, the inner sole(40) is installed on the top of the insole(10).

(17) Continuously, the sock lining(50) is made of low-density absorbing materials such as low-density urethane foam, which has relatively low density as compared to the inner sole(40), for preventing microdamage of muscles due to sharply declining elasticity depending on weight, thereby being arranged on the top of the inner sole(40). Here, the sock lining(50) is wrapped and attached to felt or fabric on the top and the bottom for preventing sharply declining elasticity depending on weight.

(18) Continuously, the upper(60) is bonded to the lower edge of the inner sole(40) and the inner side of the upper edge of the sole(20). Here, the upper(60) may be manufactured by any one of Moccasin Construction, California Vulcanize Construction, and Bolognese Construction, for arranging the inner sole(40) and the sock lining(50).

(19) Meanwhile, as shown in FIGS. 5 to 7, the custom shoes for preventing diabetes, preventing diabetic foot caused by diabetic complications and easing ulcer pain of diabetic necrosis(100) according to other embodiments of the present invention further comprise a custom insert(70), made of EVA material, for forming holes(71) in injuries of a user and for being installed to the top of the sock lining(50) in order to prevent injuries of a user from directly touching the sock lining(50). Here, as shown in FIG. 8, the custom insert(70) may be arranged on the bottom of the sock lining(50).

(20) Hereinafter, manufacturing processes for the custom shoes for preventing diabetes, preventing diabetic foot caused by diabetic complications and easing ulcer pain of diabetic necrosis according to the present invention will be described in detail with the accompanying drawing.

(21) First, the pre-manufactured deformation prevention frame(30) is fixedly inserted into a metal mold, and urethane is put inside the metal mold to manufacture the sole(20).

(22) Then, the external surface of the deformation prevention frame(30), exposed to the side edge of the sole(20), is combined to the sole(20), thereby preventing the sole(20) from being twisted without an additional midsole.

(23) Then, the insole(10) sticks to the pre-manufactured sole(20) using adhesive: columns(11) of the insole(10) are inserted and adhere to insertion grooves(23) of the sole(20).

(24) Further, the inner sole(40), the sock lining(50) and the upper(60) may be combined by using any one of Moccasin Construction, California Vulcanize Construction, and Bolognese Construction.

(25) Under this condition, by applying adhesive to the top edge of the sole(20) and the bottom edge of the inner sole(40) of the upper(60), wherein the inner sole(40) and the sock lining(50) are combined to the bottom, for combination, the sole(20) is attached to the upper(60), thereby manufacturing shoes.

(26) Meanwhile, as for the custom insert(70), holes(71) are arranged to an area corresponding to injuries of a user in the custom insert(70) which fits in a size of shoes and then, the custom insert(70), manufactured, may be arranged on the bottom of the sock lining(50).

(27) Accordingly, the custom shoes for preventing diabetes, preventing diabetic foot caused by diabetic complications and easing ulcer pain of diabetic necrosis(1) according to the present invention disperse plantar pressure by springs(11) and columns(13) of the insole(10); protect weakened bones and muscles by avoiding impact; prevent dead skin cells, calluses, and corns by continuously massaging footpad during shock absorption and recovery of the insole to which the springs(11) are inserted, and by naturally keeping warm and moisturized; and get over dead skin cells, corns, and calluses by softness and moisturizing due to impact alleviation on the bottom.

(28) Further, midsoles are generally sticked to shoe lasts to prevent shoes from creasing according to the present invention. According to the present invention, it enables to resolve walking with a waddle due to bent or creased shoes by combining the deformation prevention frame(30), which acts as midsoles, and the sole(20) integrally without using midsoles; express unique styles by exposing the deformation prevention frame(30) outside and forming patterns in the middle of the sole(20); indicate a status of a patient with diabetes for helping ambulance workers or doctors easily check the status of the patient with diabetes upon emergency; and expand foot muscles due to increase of shoes' weights using the deformation prevention frame and prevent sugar, broken down in digestive systems, from discharging in a form of urine for storing sugar to muscles fast, thereby preventing diabetes.

(29) Further, according to the present invention, by keeping on rolling smoothly while walking with using strong springs, which is to be inserted and shot out, at the rear and less stronger in the front as springs, which disperse pressure; reinforcing the rear which applies more weight; and wrapping an upper with shoe liners, shot out with fabric such as foaming sponge or urethane instead of midsoles, for manufacturing shoes, springs and columns disperse plantar pressure naturally for alleviating more impact, thereby simultaneously implementing pressure dispersion and impact alleviation, which are the essential requirements for preventing diabetic foot.

(30) Further, according to the present invention, the bottom of shoes gets soft since shoes are manufactured without using hard midsoles; columns and projected massaging protrusions of insoles massage footpad smoothly, thereby promoting blood circulation, increasing temperature of footpad, and functioning well in warmth and moisturizing; and sock lining is made of low density urethane foam for not applying weights rapidly, thereby preventing microdamage of muscles due to sharply decreased elasticity.

(31) Further, according to the present invention, springs are equally spread on footpad for becoming the bottom evenly; postures may be corrected, such as straightening back, to avoid leaning in a particular direction in footpad; bad postures, dead skin cells, corns, or calluses may be prevented by absorbing impact of walking softly and spreading weights of footpad equally for the even footpad; under no hard midsoles and no high plantar pressure, dead skin cells or calluses are naturally recovered by walking with shoes, thereby outstandingly serving to prevention of diabetic foot; and especially, in winter, due to insoles, in which springs are embedded, foot does not directly reach cold ground and air layers in embedded spaces of spring columns prevent cold air so that foot does not directly reach cold air, thereby keeping feet warm.

(32) Further, according to the present invention, pressure may be dispersed by making the heights of springs a little bit different; plantar reflex is stimulated while walking with massaging protrusions in pancreas and stomach in plantar reflex, thereby helping pancreas and stomach; and for alleviating pain in case of necrosis or ulcer in diabetic foot, custom shoe insert, made of EVA material, is recorded with necrosis areas and pierced with holes, thereby reducing pain which comes from direct touch to foot and lessening stimulation.

(33) Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
