Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insole for adjusting shoes to fit a foot and a method of using the insole.

[0002]

BACKGROUND OF THE INVENTION Since shoes are manufactured to the average shape of the foot, it is difficult to obtain a shoe that fits each person. Also, even with custom shoes,
It's not easy to fit your feet exactly. Further, when the foot is deformed or the specific part is painful, it is extremely difficult to obtain shoes that fit the foot.

Therefore, in order to fit the shoe to the foot, it has been practiced to put an insole in the shoe or attach a pad. However, even when using an insole or a pad, it is difficult to accurately match them with the foot, and trial and error are repeated, and sufficient satisfaction is often not obtained.

Therefore, the object of the present invention is to realize a shoe insole and a method of using the shoe insole for easily and accurately adjusting the shoe insole and the pad so that the foot and the shoe are fitted closely. Is.

According to the present invention, a surface layer made of an easily deformable material such as leather is provided on the lower surface of the surface layer, which softens when heated to 60 to 90 ° C and hardens at room temperature. A shoe insole having a resin layer made of a resin having properties.

Further, according to the present invention, a surface layer made of an easily deformable material such as leather is provided on the lower surface of the surface layer.
A resin layer made of a resin having a property of softening when heated to 90 ° C. and hardening at room temperature, and further, this resin layer is provided only in a portion posterior to the metatarsophalangeal joint position. Includes insoles.

Further, in the method of the present invention, each of the insoles is heated and softened, placed on a soft material, and a foot is placed on the soft material, and the foot is deformed according to the foot. , Perform a cutting process to cut this insole according to the shoe, and then, if necessary, heat this insole again to soften it and put it in the shoe, put on this shoe and put on the insole Is subjected to a realignment step of deforming the shoe according to the foot again, and thereafter, if necessary, a pad attaching step of attaching a pad formed by cutting a felt or the like into a desired shape on the insole. How to use the insole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings.

The illustrated insole 10 is formed by laminating a front surface layer 11, a resin layer 12 and a back surface layer 13, and the overall planar shape is set to be slightly larger than the shoe to be used, and the overall thickness is It is about 2 to 5 mm.

The surface layer 11 is made of an easily deformable soft material such as leather, non-woven fabric and cork. Further, as this material, a functional material having functions such as shock absorption, antibacterial, deodorant, and sweat absorption may be used. The surface layer 11 is
Although it is composed of only one layer in the illustrated example, it may be formed by laminating two or more layers.

The resin layer 12 is made of a resin having a property of softening when heated to 60 to 90 ° C. and hardening at room temperature. For example, "Renoflex" manufactured by Bayer in Germany.
(Trademark) can be used, and its thickness is suitably 1 to 2 mm. The resin layer 12 may be provided on the entire surface of the insole, but in the illustrated example, it is provided only on a portion behind the metatarsophalangeal joint (root joint of the toe). In this case, it is preferable that the front end of the resin layer 12, that is, the metatarsophalangeal joint position portion is formed so that the thickness gradually decreases so as not to feel a step.

The back surface layer 13 is formed of the same material as the front surface layer 11. The back surface layer 13 is provided as one layer in this example, but it may be provided as two or more layers. Further, when the resin layer 12 is softened (as will be described later in the usage method), it is possible to omit the back surface layer if it is allowed to adhere to or be soiled with another object.

The insole 10 is used as follows.

First, a matching step is performed. That is, the insole 10 is heated to soften the resin of the resin layer 12. For this heating, for example, an oven toaster or a hair dryer can be used. This insole 10
Is placed on a soft material that has the property of denting according to the shape of the foot when the foot is placed. Cushions, cushions, etc. can be used as this soft material, but it is convenient to prepare a dedicated urethane mat. In particular, as shown in FIG. 3, a foot-shaped recess 1 is formed on the surface of the urethane foam mat 14.
What formed 5,15 is good to use. This insole 1
Put your foot on 0, step on it, wait for a while, and cure the resin. At this time, socks may be worn, but bare feet are preferable because they have a shape that fits the feet better. The insole 10 is heated, but the surface layer 11
Is provided and the heat capacity of the insole is small, so that the heat is not particularly uncomfortable. For curing, air may be blown with a fan, a hair dryer or the like to accelerate the cooling. As a result, the insole 10 is deformed into a shape that fits the foot.

Next, a cutting process is performed. That is, the insole 10 is cut with scissors into a shape that fits the shoe, and the shoe is placed inside the shoe. This makes the shoe fit the foot.

Next, if necessary, a realignment step is performed. In the cutting step, since the inner shape of the shoe is usually smaller than the overall shape of the foot, of the foot shapes formed on the insole,
The fifth finger side portion will be removed, and the insole and the foot will not always match exactly. Normally, this condition does not cause any inconvenience, but if it is desired to more accurately match the foot, this step is performed. That is, the insole 10 is heated again to be softened, put in the shoe, put on the shoe, and wait until it hardens. This allows the insole 1
0 deforms again and becomes a shape that exactly fits the foot. At this time, since the insole is placed on the insole of the shoe, a large deformation cannot be caused unlike the above-mentioned matching step, but in this step, only a small deformation is caused. can get.

Next, if necessary, a pad attaching step is performed. This step is carried out when the fit is insufficient only by the deformation of the insole 10 described above, when the foot is deformed, or when there is a painful part in the foot. That is, a felt, a rubber plate or the like is cut into an appropriate shape to form a pad, and the pad is attached to the front surface or the back surface of the insole 10. At this time, since the insole 10 has a shape having projections and depressions that match the foot, the shape and position of the pad can be easily and accurately adjusted.

[0018]

According to the insole and method of use of the present invention, since the resin layer is softened and the foot is placed and deformed, the insole can be easily and accurately fitted to the foot. Further, even when the pad is used, its position, size, etc. can be adjusted easily and accurately.

If a resin layer is provided on the entire surface of the insole,
Since the entire foot can be integrated with the shoe, it is suitable for ski shoes and the like. If the resin layer is provided only on the part rearward of the metatarsophalangeal joint position of the insole, the fingers will be able to move freely within the shoe, so it is comfortable and almost all shoes other than the above ski shoes Is suitable.
