Description

Footwear, footwear sales method, and footwear sales system

[0001] The present invention relates to footwear, a footwear sales method, and a footwear sales system.

[0002] The left and right legs of the human body are different lengths. Leg length discrepancies have a significant impact on the human body, such as tilting the pelvis or curvature of the spine, leading to lower back pain and knee pain. One cause of leg length discrepancies is the habit of stepping with one leg or constantly placing weight on one leg in sports. Treating leg length discrepancies is difficult, so measures such as attaching a footboard to the bottom of the footwear or attaching an insole to the heel are often used to raise the foot (see Patent Document 1).

[0003] Japanese Patent Application Laid-Open No. 2007-307378

[0004] However, when attaching a footwear insole to the sole of a footwear, depending on the thickness of the insole, the appearance of the left and right footwear bodies can differ significantly, resulting in an unattractive appearance. When attaching an insole to the heel, partial heightening is required, and the size of the footwear must be slightly increased. Therefore, the object of the present invention is to provide footwear, a footwear sales method, and a footwear sales system that can compensate for leg length discrepancies without significantly differing the appearance of the left and right footwear bodies or increasing the size of the footwear body.

[0005] In the footwear of the present invention, one footwear body has a standard depth, and the other footwear body has a predetermined depth that is deeper than the standard depth, and an insole is arranged on the other footwear body so as to compensate for the difference between the predetermined depth and the standard depth.

[0006] The footwear selling method of the present invention involves one footwear body having a standard depth and being prepared in multiple pieces corresponding to foot sizes, and the other footwear body having a predetermined depth deeper than the standard depth and being prepared in multiple pieces with the predetermined depth varying for each size corresponding to the leg length difference between the feet, measuring the user's foot size and leg length difference, selecting one footwear body corresponding to the size, selecting the other footwear body corresponding to the leg length difference, and selecting an insole that compensates for the difference in depth between the predetermined depth and the standard depth, and selling the footwear.

[0007] The footwear sales system of the present invention comprises a memory unit that stores the types of the plurality of prepared footwear bodies, one of which has a standard depth and is prepared in multiple units corresponding to foot sizes, and the other of which has a predetermined depth deeper than the standard depth and is prepared in multiple units with the predetermined depth changed for each size corresponding to a difference in leg length between the feet, the user's foot size and leg length difference being measured, and a control unit that references data on the type of the footwear body, selects one of the footwear bodies corresponding to the size, selects the other footwear body corresponding to the leg length difference, and selects an insole that compensates for the difference in depth between the predetermined depth and the standard depth.

[0008] According to the present invention, the difference in leg length can be compensated for without making the appearances of the left and right footwear bodies too different and without increasing the size of the footwear body.

[0009] Fig. 1 is a perspective view showing a last according to an embodiment of the present invention. Fig. 2 (A) and (B) are cross-sectional views taken along line II-II in Fig. 1, with Fig. 2 (A) being a cross-sectional view of a last for a left foot and Fig. 2 (B) being a cross-sectional view of a last for a right foot. Fig. 3 (A) is a cross-sectional view of a footwear main body for a left foot and Fig. 3 (B) is a cross-sectional view of a footwear main body for a right foot. Fig. 4 is a diagram showing an example of a type of footwear main body. Fig. 5 is a flowchart showing an embodiment of a method for selling footwear. Fig. 6 is a diagram showing an embodiment of a sales system.

[0010] An embodiment of the present invention will be described below with reference to the drawings. [Footwear Configuration] Fig. 1 shows a footwear last (also called a wooden shoe tree) 11. The last 11 is made of wood, plastic, or the like, and is the base mold on which the footwear is made. When manufacturing footwear, although not shown in the drawings, an upper is placed over the last 11, and the upper is aligned with the last 11 and secured with an adhesive, and the upper is made to fit the last 11 by, for example, tapping it to prevent wrinkles. Finally, the heel is nailed and the sole is attached to complete the product. The size of the footwear is determined by the last 11.

[0011] If the last 11 is the same, even if the design is different, the size and internal space of the footwear will be the same shape during the manufacturing process.

[0012] Generally, the left and right legs of a human body are different in length. Since it is difficult to correct the leg length discrepancy itself, in this embodiment, footwear is raised. In particular, this embodiment is suitable for spiked shoes (not shown) used in golf, soccer, and other sports.

[0013] 2(A) and 2(B) are cross-sectional views taken along line II-II in FIG. 1. FIG. 2(A) shows a last 11 for a left foot, which has a reference height H1. FIG. 2(B) shows a last 21 for a right foot, which has a predetermined height H2 that is higher than the reference height H1. The two lasts 11, 21 have the same shape except for the heights H1 and H2. In this embodiment, the difference between the reference height H1 and the predetermined height H2 is a height H3, and the difference in height H3 corresponds to the difference in leg length. The height H3 is uniform throughout the entire area of ​​the bottoms 11A, 21A of the lasts 11, 21, including in the longitudinal and lateral directions.

[0014] FIG. 3(A) is a cross-sectional view of a footwear body (one footwear body) 31 for, for example, a left foot. The footwear body 31 is manufactured using a last 11. The footwear body 31 has a reference depth D1 corresponding to a reference height H1. 15 denotes a glued or nailed heel. FIG. 3(B) is a cross-sectional view of a footwear body (the other footwear body) 41 for, for example, a right foot. The footwear body 41 is manufactured using a last 21. The footwear body 41 has a reference depth D2 corresponding to a reference height H2. 15 denotes a glued or nailed heel. Here, the difference between the reference depth D1 and the reference depth D2 is a depth D3, and the difference in depth D3 corresponds to the difference in leg length between the left and right feet.

[0015] An insole 51 is placed on the other footwear body 41. The insole 51 has a uniform thickness T, which corresponds to a depth D3 that is the difference between the reference depth D1 and a predetermined depth D2. The insole 51 of the uniform thickness T is placed on the other footwear body 41 to compensate for the difference in depth D3.

[0016] In this embodiment, two lasts 11, 21 are produced that differ in height by H3 to accommodate the difference in leg length between the user, as shown in Fig. 2, and left and right footwear bodies 31, 41 are manufactured using the lasts 11, 21 as shown in Fig. 3, with an insole 51 placed in the other footwear body 41 to compensate for the difference in depth D3. With this configuration, even if there is a difference in leg length between the user's left and right feet, as shown in Figs. 3(A) and 3(B), the left foot rests on the bottom of the footwear body 31 and the right foot rests on the insole 51, thereby compensating for the difference in leg length between the user.

[0017] In this embodiment, the footwear bodies 31, 41 are manufactured using lasts 11, 21 that differ only in height, so that the shapes, such as size, except for the depths D1, D2, are approximately the same, and the difference in leg length can be compensated for without significantly changing the appearance of the footwear bodies 31, 41 or increasing the size of the footwear bodies 31, 41.

[0018] [Configuration of sales method] In this embodiment, when selling footwear, first, the difference in leg length between the user's feet is measured, and then one footwear body 31 and the other footwear body 41 that correspond to the difference in leg length between the user's feet are selected from multiple prepared footwear bodies 31, 41 and sold.

[0019] 4 shows examples of the types of footwear bodies 31 and 41. The footwear body 31 is prepared in four sizes, slim, medium, wide, and super wide, with the same depth D1. These are manufactured using the last 11 shown in FIG. 2(A).

[0020] The other footwear body 41 is manufactured to correspond to the difference in leg length between users, with the depth D2 being varied to 5 mm, 10 mm, and 15 mm, and 12 types are prepared. These are manufactured using each last 21 with the height H3 of the last 21 shown in FIG. 2(B) varied to 5 mm, 10 mm, and 15 mm.

[0021] On the other hand, the footwear bodies 41 with a depth D2 difference of 5 mm are prepared in four sizes: slim 5 mm, medium 5 mm, wide 5 mm, and super wide 5 mm. The footwear bodies 41 with a depth D2 difference of 10 mm are prepared in four sizes: slim 10 mm, medium 10 mm, wide 10 mm, and super wide 10 mm. The footwear bodies 41 with a depth D2 difference of 15 mm are prepared in four sizes: slim 15 mm, medium 15 mm, wide 15 mm, and super wide 15 mm.

[0022] 5 shows a flowchart. In step S1, at least four types of one footwear body 31 and 12 types of the other footwear body 41 are prepared. These footwear bodies 31, 41 are preferably prepared in a store that sells footwear. The number of footwear bodies is not limited to four or 12. More types of footwear may be prepared by subdividing the footwear bodies.

[0023] In step S2, the user's foot size and the leg length difference between the left and right legs are measured. The leg length difference is measured by a doctor. For example, a visual target line is drawn on the user's lower back as it appears on an X-ray, and the leg length difference is calculated from the inclination angle of the visual target line.

[0024] In step S3, based on the user's foot size, one footwear body 31 is selected from one of the four types of footwear bodies 31. If the user's foot size is slim, slim is selected; if it is medium, medium is selected; if it is wide, wide is selected; if it is super wide, super wide is selected.

[0025] In step S4, based on the difference in leg length between the user's feet, one footwear body 41 is selected from 12 types of other footwear bodies 41. If the user's foot is slim, one is selected from slim 5 mm, slim 10 mm, and slim 15 mm; if the user's foot is medium, one is selected from medium 5 mm, medium 10 mm, and medium 15 mm; if the user's foot is wide, one is selected from wide 5 mm, wide 10 mm, and wide 15 mm; and if the user's foot is superwide, one is selected from superwide 5 mm, superwide 10 mm, and superwide 15 mm.

[0026] In step S5, an insole 51 is selected to be placed on the bottom of the other footwear body 41. Here, three types of insoles 51 with different thicknesses T, 5 mm, 10 mm, and 15 mm, are prepared in advance.

[0027] In step S6, the leg length discrepancy of the user is eliminated, and the footwear that compensates for the leg length discrepancy of the user's legs is sold.

[0028] In this embodiment, one footwear body 31 is selected according to the foot size, the other footwear body 41 is selected according to the leg length difference, and the insole 51 is selected for the other footwear body 41 according to the leg length difference, and then sold. With this configuration, even if there is a leg length difference between the user's left and right feet, the footwear purchased will compensate for the leg length difference, improving convenience. In this case, the left and right footwear bodies 31, 41 do not differ much in appearance, and there is no noticeable difference in size between the left and right.

[0029] [Configuration of Sales System] Fig. 6 is a diagram showing the sales system. The sales system 70 includes an input unit 71, a storage unit 72, a control unit 73, and an output unit 75. The storage unit 72 stores, for example, an example of the types of footwear bodies 31, 41 shown in Fig. 4. The input unit 71 receives input of the user's foot size and the difference in leg length between the left and right feet. A doctor measures the difference in leg length between the user's feet.

[0030] The control unit 73 references the data on the types of footwear bodies 31, 41 stored in the memory unit 72, selects one footwear body 31 based on the user's foot size input from the input unit 71, and selects the other footwear body 41 based on the difference in leg length between the users. The control unit 73 also selects an insole 51 of one thickness T from three thicknesses T of 5 mm, 10 mm, and 15 mm.

[0031] The output unit 75 outputs sales data for the selected footwear body 31 , the other footwear body 41 , and the selected insole 51 .

[0032] In this embodiment, one footwear body 31, the other footwear body 41, and the insole 51 are sold as a set in accordance with the sales data output from the output unit 75. With this configuration, even if a user has a leg length discrepancy, the footwear they purchase will compensate for the leg length discrepancy, improving convenience. In this case, the left and right footwear bodies 31, 41 do not differ significantly in appearance, and there is no noticeable difference in size between the left and right.

[0033] As explained above, the footwear, footwear sales method and sales system of this embodiment are all completely different in configuration from conventional footwear, footwear sales method and sales system. Even if there is a difference in leg length between the user's feet, the footwear purchased by the user is sold with the difference in leg length compensated for, thereby improving convenience, and the footwear bodies 31, 41 purchased do not differ much in appearance between the left and right, and there is no noticeable difference in size between the left and right.
