Description

  The present invention relates to a method for manufacturing a shoe mold, which is a mold for manufacturing shoes, and a method for manufacturing a shoe, and more particularly to a shoe manufacturing mold for a hallux valgus or a club valgus and a method for manufacturing a shoe.

  In recent years, hallux valgus and hallux valgus have become a problem. Hallux valgus is a symptom in which the thumb's thumb bends toward the little finger and the base of the thumb protrudes outwards. Hallux valgus is the symptom of the little toe bent toward the thumb and the little finger's base protrudes outwards. Symptoms. In the case of hallux valgus or hallux valgus, when walking with normal shoes, the protruding part is pressed against the inner surface of the shoes, causing pain.

  Here, conventionally, some shoes for hallux valgus have a larger overall width.

  Conventionally, as a shoe mold for shoes for hallux valgus, a mold for providing a built-up portion on the side of the thumb side of the shoe mold near the maximum width of the mold, and such a shoe mold There is a method of manufacturing shoes using a lip (Patent Document 1). In Patent Document 1, as the size of the build-up portion, the major axis of the seat portion is about 1 to 3 cm, the width is about 0.5 to 2 cm, and the height is about 0.3 to 1 cm. Yes.

  Also, conventionally, a special shoe mold with a deformed protrusion of the foot is made, and using this shoe mold, a hole is made in the portion corresponding to the top of the protruding portion of the foot or the thickness of the portion is reduced. A pad of flexible material is molded into a pad with a thickness determined so that a smooth outer contour is formed when the pad is applied to the deformed protrusion of the foot. There is a method of manufacturing a shoe according to a normal shoe making process by inserting it between an inner doubler and a back skin and temporarily attaching it to a predetermined position (Patent Document 2).

  Moreover, the applicant knows the prior art documents of patent documents 3-5.

JP 2002-209610 A Japanese Utility Model Publication No. 62-131603 Japanese Patent No. 3479019 Japanese Patent No. 4087747 JP 2008-206916 A

  However, the shoes for hallux valgus with the overall width of the shoe responding to the deformed foot width, but because there is too much room around the instep, the foot moves back and forth in the shoe by walking. , There is a problem of causing shoe rubbing.

  Further, in the shoe manufacturing method described in Patent Document 1, since the size of the built-up portion cannot be adjusted, a problem that the mold cannot be manufactured in accordance with the size of the protruding portion due to the deformation. There is. For example, if the mold is selected according to the size of the foot length or instep, the size of the build-up part may not match, and the size of the build-up part that matches the size of the protruding part of the foot deformed If you choose a type, there is a risk that the foot length and instep will not fit.

  In addition, in the shoe manufacturing method disclosed in Patent Document 2, a dedicated shoe mold manufacturing method in which a deformed protrusion of a foot is formed is not clear.

  Therefore, according to the present invention, a shoe can be manufactured according to the size of a protruding portion that is deformed and protruded by a hallux valgus or a valgus, and when the shoe is worn, the protruding portion is not pushed inside the shoe. It is an object of the present invention to provide a method for manufacturing a shoe that is not painful and that is less likely to cause the foot to move back and forth.

  The present invention has been created to solve the above-described problems. First, a method for manufacturing a shoe mold, which is a mold for manufacturing shoes, is a foot on a foot of a user of a shoe to be manufactured. A measurement process for measuring the length, foot circumference and instep, a calculation process for calculating the thickness of the affixed member using the measurement value of the foot circumference and the measurement value of the instep obtained in the measurement process, and calculation in the calculation process In the loop-shaped curve corresponding to the foot circumference in the shoemaking mold according to the measured value of the foot length and the measured value of the instep around the pasted member creating step for creating the pasted member having the measured thickness And a pasting step of pasting the pasting member created in the pasting member creating step on the side including the inner position and / or the side including the outer position.

  According to the shoe manufacturing method of the first configuration, the thickness of the affixing member can be adjusted by calculating and determining the thickness of the affixing member based on the measured value of the foot circumference and the measured value of the instep. By manufacturing shoes using a shoemaking mold, shoes can be manufactured according to the size of the protruding part that deforms and protrudes due to hallux valgus or club valgus, and when the shoes are worn, the protruding parts Because it is not pushed inside the shoe, it is not painful. In addition, because the instep uses a shoe-making mold according to the measured value, even if the foot circumference is larger than usual, the instep does not increase, and the shoe tightens the foot at the place around the instep, When wearing shoes, there is little risk that the foot will slip back and forth in the shoe, and there is no risk of scuffing.

  Secondly, in the first configuration, the shoemaking mold before the application member is applied is set so that the length of the foot circumference = the length of the instep + n (n is a positive number), In the calculation step, the thickness of the affixing member is calculated by a calculation formula of (measured value of foot circumference−measured value of instep circumference−n) / 2. Therefore, the thickness of the sticking member can be calculated appropriately.

  Thirdly, in the first configuration, the shoemaking mold before attaching the attaching member is set so that the length of the foot circumference = the length of the instep + n (n is a positive number), In the above-mentioned pasting member creation step, an inclined surface is formed so that the area around the pasting member becomes thinner toward the peripheral edge, the length in the tilting direction on the inclined surface is h1, and the measured value of the foot circumference is In the above calculation step, the thickness of the affixing member is calculated by the formula (A), where V is V and the measured value around the instep is W.

  Therefore, when providing an inclined surface in order to eliminate the level | step difference with the edge part around a sticking member, the thickness of a sticking member is appropriately computable.

  Fourth, in the first configuration, the shoemaking mold before attaching the attaching member is set so that the length of the foot circumference = the length of the instep + n (n is a positive number), In the above-mentioned pasting member creation process, an inclined surface is formed so that the area around the pasting member becomes thinner toward the peripheral edge, and corresponds to the length of the tilted surface on the opposite side of the tilted surface. In the above calculation step, the thickness of the affixing member is calculated by the formula (B), where h2 is the measured length, V is the measured value of the foot circumference, and W is the measured value of the instep. .

  Therefore, when providing an inclined surface in order to eliminate the level | step difference with the edge part around a sticking member, the thickness of a sticking member is appropriately computable.

  In addition, fifthly, in any one of the first to fourth configurations, in the shoemaking mold, the foot length, the foot girth, and the instep circumference are set with predetermined dimensions for each length. In the pasting process, if there is no dimension that matches the measured value for the foot length, select a dimension that is larger than the measured value and closest to the measured value, and if there is a dimension that matches the measured value. Select the dimension, and if there is no dimension that matches the measured value for the instep, select the dimension that is smaller than the measured value and closest to the measured value, and the dimension that matches the measured value is In some cases, by selecting the size, a shoe-making shape corresponding to the value of the foot length and the value of the instep is obtained.

  Sixthly, in any one of the first to fifth configurations, the measurement step measures the foot length of the foot along a front-rear direction linear portion indicating a direction for measuring the foot length. Toe side of the front-rear direction straight line portion at the position of 61.5-71.5% of the foot length measured by the foot length measuring step from the foot end measuring step and the rear end point of the foot heel in plan view The angle between the direction of the foot and the inner direction with respect to the foot placement position of the measure part for measuring the foot circumference is 69.0 to 79.0 degrees for men and 68.0 for women. Measure the foot circumference by placing the measure part so that it is ˜78.0 degrees, and the foot length measured by the foot length measurement process from the rear end point of the foot heel in plan view Measure the toe-side direction and foot circumference of the front-rear direction straight line portion at a position of 51.0-61.0%. The angle formed by the inner direction with respect to the arrangement position of the foot of the measure part is 75.5 to 85.5 degrees for men and 74.5 to 84.5 degrees for women. Thus, it has an instep measurement process which arrange | positions a measure part and measures an instep. Therefore, it is possible to appropriately measure the foot length, the foot circumference, and the instep.

  Seventhly, in any one of the first to sixth configurations, a shoe manufacturing method, wherein the shoe manufacturing method is the first, second, third, fourth, fifth or sixth method. A shoe is manufactured using the manufactured shoe mold.

  Therefore, since the thickness of the affixing member can be adjusted by calculating the thickness of the affixing member based on the measured value of the foot circumference and the measured value of the instep, the thickness of the affixing member can be adjusted. A shoe can be manufactured according to the size, and when the shoe is worn, the protruding portion is not pushed into the inside of the shoe, so that there is no pain. In addition, because the instep uses a shoe-making mold according to the measured value, even if the foot circumference is larger than usual, the instep does not increase, and the shoe tightens the foot at the place around the instep, When wearing shoes, there is little risk that the foot will slip back and forth in the shoe, and there is no risk of scuffing.

  Eighth, a method for manufacturing a shoe mold, which is a mold for manufacturing shoes, measures the foot length and instep around the user's foot of the shoe to be manufactured, and measures the length of the foot obtained by the measurement. By manufacturing shoes using a shoe mold according to the measured value and the measured value of the instep, even if the foot of the shoe user is deformed due to disease etc., the foot is fixed at the position of the instep It is characterized by preventing the foot from moving back and forth in the shoe.

  According to the shoe mold manufacturing method and shoe manufacturing method according to the present invention, the thickness of the affixing member can be adjusted by calculating and determining the thickness of the affixing member based on the measured value of the foot circumference and the measured value of the instep. , Shoes can be manufactured according to the size of the protruding part which is deformed and protruded by hallux valgus or club valgus, and it is painful because the protruding part is not pushed inside the shoe when wearing shoes There is no. In addition, because the instep uses a shoe-making mold according to the measured value, even if the foot circumference is larger than usual, the instep does not increase, and the shoe tightens the foot at the place around the instep, When wearing shoes, there is little risk that the foot will slip back and forth in the shoe, and there is no risk of scuffing.

  In the present invention, a shoe can be manufactured according to the size of the protruding portion that is deformed and protruded by the hallux valgus or the varus valgus, and when the shoe is worn, the protruding portion is not pushed into the inside of the shoe. The object of providing a method for manufacturing a shoe that does not accompany the foot and is less likely to cause the foot to move back and forth is realized as follows.

  The method for manufacturing a shoe in the present invention measures a foot size, selects a wooden model as a shoe-making mold (a shoe-making mold or a shoe mold. The same applies to others) based on the measured foot size, and a hallux valgus or Calculate the thickness of the affixing member to be applied to the location corresponding to the protruding part that is deformed and protruded by the inner mallet, affix the affixing member of the thickness to the wooden mold, and paste the affixing member to the tree Manufacture shoes using the mold.

  The shoe mold manufacturing method and shoe manufacturing method of the present embodiment will be described more specifically with reference to FIG. 1 and the like. First, the foot length, foot circumference and instep circumference of the user of the shoe to be manufactured are measured. (S1, measurement process).

  First, for the foot length A, as shown in FIG. 2, the length from the position of the vertical line (rear end point) dropped from the rear end of the heel to the position of the vertical line dropped from the tip of the foot is measured. The tip of the foot is the longest part of the foot. In other words, the human foot usually has either the thumb or the second finger protruding most at the tip of the foot, but the most protruding portion is the tip of the foot. For example, as shown in FIG. 2, the foot length A is measured by aligning the rear end of the heel and the tip of the foot with a straight portion (center line) a in the front-rear direction. Note that the foot length may be measured using the tip of the second finger as the tip of the foot.

  For the foot circumference, the circumference of the foot connecting the widest part of the foot, that is, the base of the thumb (thumb) and the base of the little finger is measured.

  Specifically, as described below, it is preferable to measure the foot circumference by arranging a measure portion at a predetermined angle with respect to the front-rear direction linear portion at a position of a predetermined length from the rear end point of the foot. That is, as shown in FIG. 2, the front-rear direction straight line at a position P1 at a ratio of 61.5 to 71.5% (preferably 66.5%) from the rear end point of the foot in plan view to the foot length. The angle α1 formed by the direction of the toe side of the part a and the inner direction with respect to the foot placement position of the measure part (tape measure) for measuring the foot circumference is 69.0 to 79.0 degrees in the case of males (preferably Measure the foot circumference by placing the measure part at 74.0 degrees. That is, in FIG. 2, the ratio of the length b to the foot length A is 61.5 to 71.5% (preferably 66.5%), and a curve (loop-like curve) B representing the foot circumference is When viewed in plan, the curve B (straight line in plan view) passes through the position P1 of b from the rear end point of the heel, and the angle between the toe side of the front-rear direction straight line portion a and the curve B (placement of the foot) The inner angle of the position) α1 is 69.0 to 79.0 degrees (preferably 74.0 degrees). Then, the measure portion is arranged along the curve B in a state where the measure portion is linearly extended under the foot, and 61.5 to 71.5% (preferably from the rear end point of the foot to the foot length). 66.5%) passing through the position P1, and the direction of the toe side of the front-rear direction straight line part a and the inner direction of the measure part (tape measure) for measuring the foot circumference with respect to the foot placement position. The measure portion is arranged so that the formed angle α1 is 69.0 to 79.0 degrees, and then the measure portion is wound around the foot to measure the foot circumference. In addition, when viewed from the side of the foot, the angle α2 formed by the curve representing the foot circumference and the horizontal plane is substantially perpendicular (or may be a right angle). In a side view from the inside, the angle of the measure part with respect to the horizontal plane is set to be substantially right angle (or right angle).

  In the case of a woman, the angle α1 is set to 68.0 to 78.0 degrees (preferably 73.0 degrees), and the others are the same.

  For the instep, measure the circumference of the foot of the highest part of the foot at a position above the arch.

  Specifically, as described below, it is preferable to measure the instep by placing a measure portion at a predetermined angle with respect to the front-rear direction linear portion at a predetermined length from the rear end point of the foot. That is, as shown in FIG. 2, at a position P2 at a ratio of 51.0 to 61.0% (preferably 56.0%) with respect to the foot length from the rear end point of the foot heel in plan view, The angle β1 formed by the direction of the toe side of the direction straight line part a and the inner direction with respect to the foot placement position of the measure part for measuring the foot circumference is 75.5 to 85.5 degrees for men (preferably Measure the foot circumference by placing the measure portion so that the angle is 80.5 degrees. That is, in FIG. 2, the ratio of the length c to the foot length A is 51.0 to 61.0% (preferably 56.0%), and a curve (loop-like curve) C representing the instep is represented. When viewed in plan, the curve C (straight line in plan view) passes through the position P2 of the c from the rear end point of the heel, and the angle between the toe side of the front-rear direction straight line portion a and the curve C (placement of the foot) The angle on the inner side of the position) β1 is 75.5 to 85.5 degrees (preferably 80.5 degrees). Then, the measure portion is arranged along the curve C in a state where the measure portion is linearly extended under the foot, and 51.0 to 61.0% (preferably from the rear end point of the foot to the foot length). 56.0%) through the position P2, and the direction of the toe side of the front-rear direction straight line portion a and the inner direction of the foot portion of the measure portion (tape measure) for measuring the foot circumference. The major part is arranged so that the formed angle β1 is 75.5 to 85.5 degrees (preferably 80.5 degrees), and then the instep is measured by winding the major part around the foot. When viewed from the side of the foot, the curve representing the instep is such that the angle β2 made with the toe side of the horizontal plane is 71.0 to 81.0 degrees (preferably 76.0 degrees). As for the measure for measuring the instep, when the side is viewed from the inside of the foot, the measure portion is 71.0-81.0 degrees (preferably 76.0 degrees) with respect to the toe side of the horizontal plane. To be.

  In the case of a woman, the angle β1 is 74.5 to 84.5 degrees (preferably 79.5 degrees), and the others are the same.

  In addition, in order to measure a foot length, a foot circumference, and an instep circumference, it is preferable to use the foot size measuring tool of the said patent documents 3-5.

  The foot size measuring tool A described in Patent Documents 3 and 4 is configured as shown in FIG. 3, and a substantially rectangular sheet-like member 5 includes a foot display unit 10, a foot length measuring unit 20, It has a foot circumference measurement unit 30, an instep measurement unit 40, and the like.

  Further, a foot size measuring tool 1 described in Patent Document 5 is configured as shown in FIGS. 4 and 5 and has a measuring tool main body 1A. The measuring tool main body 1A includes a main body region 5. 4 and a foot rest measuring unit 40 on the front side surface of the main body region 5 as shown in FIG. And an instep measurement unit 50 and an entry field 68. On the back surface of the main body region unit 5, as shown in FIG. 5, a foot type display unit 110, a foot length measurement unit 120, and a foot It has a surrounding measurement unit 140, an instep measurement unit 150, and an entry field 168. In particular, when measuring the foot circumference by placing the measure part at a predetermined angle from the rear end point of the foot and at a predetermined angle with respect to the linear part in the front-rear direction, or at the position of the predetermined length from the rear end point of the foot In the case of measuring the instep by placing the measure portion at a predetermined angle with respect to the front-rear direction straight portion, it is preferable to use the foot size measuring tool shown in Patent Document 5.

  As described above, when the foot length, the foot circumference, and the instep of the foot are measured, the measurement of the foot length obtained by the measurement and the wooden pattern (shoemaking type) 1010 corresponding to the measurement value of the instep are selected ( S2). In addition, as a premise, since the standard is prepared according to the length of the foot length, the instep, and the foot circumference, the wooden shape having a size close to the measured value is selected. That is, for the foot length, if there is no dimension that matches the measured value, select the dimension that is larger than the measured value and is closest to the measured value, and if there is a dimension that matches the measured value, Select dimensions. For the instep, if there is no dimension that matches the measured value, select the dimension that is smaller than the measured value and closest to the measured value, and if there is a dimension that matches the measured value, Select dimensions. That is, for the instep, the dimensions are selected as described above in order to fix the foot at the position around the instep.

  That is, the foot length is prepared for each predetermined length (for example, every 5 mm), and the instep and foot circumference are prepared for each predetermined length (for example, every 4 mm). The instep and foot circumference are set such that a value obtained by adding a predetermined length to the instep circumference is the foot circumference. For example, the length of the foot circumference = the length around the instep + n (n is a positive number) is set, and the value of n is, for example, 2 mm. The length may be other than 2 mm.

  For example, for the foot length, the next of 250 mm at a pitch of 5 mm is set to a size of 255 mm, and for the instep, the next of 246 mm at a pitch of 4 mm is set to a size of 250 mm. If the measured foot length is 253 mm and the instep is 249 mm, a wooden pattern with a foot length of 255 mm and an instep of 246 mm is selected. Since the instep is 246 mm, the wooden foot circumference is 248 mm (246 mm + 2 mm).

  In the above example, if the measured value of the instep is 250 mm, a wooden pattern with an instep of 250 mm is selected. Since the instep is 250 mm, the wooden foot circumference is 252 mm (250 mm + 2 mm).

  Although the tree pattern is selected from a plurality of types prepared in advance, a tree pattern with the selected dimensions may be created.

  Next, the thickness of the affixing member 1020 is calculated from the measured foot circumference and instep value (S3, calculation step). Here, since the thickness h of the affixing member 1020 is as shown in Expression (1), it is calculated according to Expression (1).

h = (Measured value of foot circumference-Measured value of instep-n) / 2 Formula (1)
That is, according to the schematic diagram shown in FIG. 6, when the plate-like pasting member 1020 is pasted on the wooden mold 1010, the foot circumference becomes longer by the length corresponding to two of the thickness of the pasting member. Foot circumference (= measured value of foot circumference) = measured value of instep circumference + n + 2 × h, and the above formula is derived from this formula. That is, the thickness of the affixing member can be calculated from the measured value of the foot circumference, the measured value of the instep and the preset value of n. For example, in the case of a wooden pattern, when the value of n in the length of the foot circumference = the length of the instep + n is set to 2 mm, n in the formula (1) is calculated as 2 mm. In the schematic diagram of FIG. 6, a dotted line represents a foot circumference line. In addition, when the value obtained by subtracting the measured value of the instep from the measured value of the foot circumference is n or less, the pasting of the pasting member is not necessary.

  Next, a pasting member is created according to the calculated thickness of the pasting member (S4, pasting member creating step). When creating the affixing member, for example, a plate-like member made of synthetic resin (for example, synthetic leather or synthetic rubber) is used, and the plate-like member is shown in the elliptical shape shown in FIG. 7 (a) or in FIG. 8 (a). It is formed in a shape in which both ends of the rectangular shape are formed in an arc shape. In addition, as a planar shape of FIG. 8, you may form a rectangular corner | angular part in circular arc shape besides forming rectangular both ends in circular arc shape.

  If the thickness of the plate member is insufficient, a plurality of plate members are stacked and bonded together. Further, when the thickness of one plate-like member or a plate-like member obtained by bonding a plurality of plates is larger than a desired thickness, the plate-like member is scraped with a sharpening tool (for example, a file). Moreover, the edge part (or circumference | surroundings) of a plate-shaped member is the area | region of the periphery of the affixing member 1020, as shown in FIG.7 (b) and FIG.8 (b) so that the level | step difference with the wooden surface may not arise. It is preferable that the inclined surface 1020a is formed by cutting. That is, the area around the pasting member 1020 is inclined obliquely.

  In addition, when the edge part of a plate-shaped member is inclined diagonally so that a level | step difference with a wooden surface may not arise, you may be as follows. That is, as shown in FIG. 9, the length of the inclined portion of the inclined portion in the inclined direction is h1, the length of the horizontal portion with respect to the inclined surface (the length of the inclined surface on the opposite side of the inclined surface (in the inclined direction) The length corresponding to the length) is h2 (h2 = h1 cos γ), the thickness of the affixing member is h3, the length of the foot circumference that becomes longer for one inclined portion by pasting the affixing member is U, If the measured value of V is V and the measured value of the instep is W, the foot circumference of the shoe to be manufactured (= measured value of the foot circumference: V) = W + n + 2 × U (this equation is expressed as equation (2)), U Is represented by equation (3) from the schematic diagram of FIG. In the schematic diagram of FIG. 9, a dotted line represents a foot circumference line.

  Then, since Expression (4) is derived from Expression (3) and Expression (2), the length of the inclined surface (length in the inclination direction) h1 is determined by Expression (4), and the measured value of the foot circumference By putting the measured value of the instep, the length of the thickness of the pasting member can be determined. That is, the thickness of the affixing member can be calculated from the measured value of the foot circumference, the measured value of the instep, the length of the inclined surface (length in the inclined direction) h1, and a preset value of n. In the case of a tree pattern, for example, when the value of n in the length of the foot circumference = the length of the instep + n is set to 2 mm, n in the equation (4) is calculated as 2 mm.

  U can also be expressed as in equation (5).

  Then, since Expression (6) is derived from Expression (5) and Expression (2), the length h2 (the length corresponding to the length of the inclined surface on the surface opposite to the inclined surface is obtained by Expression (6). The length of the thickness of the affixing member can be determined by setting the measured value of the foot circumference and the measured value of the instep. That is, the thickness of the affixing member can be calculated from the measured value of the foot circumference, the measured value of the instep, the length h2, and the preset value n. In the case of a tree pattern, for example, when the value of n in the length of the foot circumference = the length of the instep + n is set to 2 mm, n in the equation (6) is calculated as 2 mm.

  Therefore, it is possible to manufacture the affixing member by manufacturing the plate-like member constituting the affixing member to the calculated thickness and further providing an inclined portion (a linear inclined portion) for a predetermined length h2. it can.

  As described above, when the affixing member 1020 is manufactured, it is affixed to the wooden pattern 1010 to create a corrected wooden pattern (corrected shoe mold) 1005 (S5, affixing step). That is, the correction wooden mold is obtained by pasting the pasting member 1020 on the side face (inner side face) including the inner position and / or the side face (outer side face) including the outer position in the loop-shaped curve corresponding to the foot circumference in the wooden pattern 1010. 1005 is created. That is, the position of the inner side surface corresponds to the position of the base of the thumb, and the position of the outer side surface corresponds to the base of the little finger. In other words, the correction wooden mold 1005 is created by pasting the affixing member 1020 on the position corresponding to the protruding portion of the foot of the shoe user (that is, the portion that is deformed and protruded by the hallux valgus or hallux valgus). .

  For example, in the case of hallux valgus, as shown in FIG. 10 and FIG. 11, the sticking member 1020 is pasted at a position corresponding to the base of the thumb in the wooden mold 1010. As shown in FIG. 13, a pasting member 1020 is pasted at a position corresponding to the base of the little finger in the wooden mold 1010. It should be noted that the length of the foot circumference in the manufactured corrected wooden mold 1005 is measured to check whether or not it matches the measured value of the foot circumference. If it is long, the affixing member 1020 is shaved, and if it is shorter than the measured value of the foot circumference, adjustments such as adhering another affixing member on the affixing member 1020 are performed.

  As described above, the corrected wooden mold 1005 as a shoemaking mold is manufactured. That is, the process from step S1 to step S5 corresponds to a shoemaking manufacturing method.

  Then, shoes are manufactured using the correction | amendment wooden mold | type 1005, ie, the wooden mold | type 1010 which affixed the affixing member 1020 (S6). The shoe manufacturing method using the corrected wooden mold 1005 is the same as the conventional method, and is a known cement type (cemented type) method, goodyear welt type method, McKay type method, stitch-down type method, California type (platform type) method. Etc.

  As an example of the cement type, an insole is fixed to the back side of the correction wooden mold 1005 and an upper (upper) is inserted. That is, the upper is put on the correction wooden mold 1005 and pressed against the correction wooden mold 5 so as not to cause wrinkles, and the upper fishing margin is bonded to the insole. The upper is previously prepared by sewing, bonding, injection molding or the like. Next, a shoe is manufactured by bonding the outsole to the bottom of the insole. Step S6 corresponds to the shoe manufacturing method.

  The above shoe manufacturing method measures the foot size (especially the foot length and instep) on the foot of the user of the shoe to be manufactured, and measures the length of the foot and the measurement of the instep. By manufacturing shoes using a shoe mold according to the value, even if the foot of the shoe user is deformed due to illness etc., the foot is fixed back and forth in the shoe by fixing the foot at the position of the instep It can be said that it is prevented from moving to.

  As described above, according to the shoe mold manufacturing method and shoe manufacturing method of the present embodiment, the thickness of the affixing member is calculated and determined based on the measured value of the foot circumference and the measured value of the instep, and Since the thickness can be adjusted, shoes can be manufactured according to the size of the protruding part that deforms and protrudes due to diseases such as hallux valgus and club folds. It will not be painful because it will not be pressed. In addition, because the instep uses a wooden shape according to the measured value, even if the foot circumference is larger than usual, the instep does not become large, and the shoe tightens the foot at the place around the instep, When wearing shoes, there is little risk that the foot will slip back and forth in the shoe, and there is no risk of scuffing.

  In addition, although the wooden shape was taken as an example as a shoemaking type | mold, it is not restricted to a wooden shape, A synthetic resin shoemaking type | mold may be sufficient.
