Description

  The present invention relates to a shoe in which a part of an insole is cushioned.

  2. Description of the Related Art Conventionally, various shoes with a sole (sole) shape have been devised in order to improve comfort and reduce foot fatigue.

For example, Patent Document 1 discloses a shoe in which an insole of a sole (sole) including an outsole (outside sole) and an insole (insole) is provided with unevenness along the shape of a foot.
In this way, when the shoe is worn, the foot fits on the insole. Therefore, compared with the case where the insole is flat, the comfort is improved and the fatigue of the foot is reduced.

However, since the insole is a foundation for shoes, it is made of a hard material such as genuine leather in consideration of its durability and shape retention.
For this reason, it has poor cushioning properties, is tired when walking for a long time, and there is still room for improvement in terms of comfort.

On the other hand, Patent Document 2 discloses a shoe in which a cushioned insole is laid on an insole.
In this way, the insole on which the foot is placed when the shoe is worn becomes a cushion, and compared with the shoe of Patent Document 1, it is comfortable to wear and the foot does not get tired much even when walking for a long time.

However, if the insole is formed separately from the insole in this way, the number of parts of the shoe increases and the cost increases.
Insole that can give a unique aesthetic and texture using genuine leather, especially tanned leather, is hidden in the insole, resulting in poor design.
JP 2002-65311 A JP-A-10-234417

  Therefore, the present invention has an object to provide shoes at a low cost that have both design and comfort.

  In order to solve the above-described problems, in the shoe according to the present invention, the insole includes a heel placing portion for placing the heel of the foot, an arch placing portion for placing the arch of the foot, and a middle foot corresponding to the back side of the instep. Only the metatarsal bone placement portion on which the bone portion is placed is formed from a resin foam having cushioning properties.

Since this shoe has a cushioning property in particular when it is walking, it absorbs shock during walking, is comfortable to wear, and does not get tired even when walking for a long time.
Moreover, since the structure which puts a leg directly on an insole is employ | adopted and it is not necessary to form an insole separately, a number of parts can be reduced and the manufacturing cost of shoes can be reduced.
In addition, an insole that can give a unique aesthetic appearance and texture without using an insole is visible directly to the outside, so that the design can be improved.
Moreover, since it does not have a cushioning property except a part which requires especially weight, it does not wobble excessively at the time of a walk, and it is easy to walk.

  When the metatarsal bone placement part is raised from the insole surface so as to follow the foot arch, the foot arch is supported in a natural state, which increases the fit and further reduces foot fatigue. At the same time, it also prevents hallux valgus.

  When the arch is placed in a shape that is raised from the insole surface along the arch of the foot, the arch of the foot is supported in a natural state, which increases the fit and further reduces foot fatigue. It also prevents flat feet.

If the part of the insole other than the cushion part is made of genuine leather, it will look very nice due to its natural luster and hue.
In addition, since genuine leather is relatively hard, the durability and shape retention of the shoes are also good, and furthermore, because the soles are firmly held, wobble during walking can be suppressed.
As such genuine leather, tanned leather tanned with tannin is particularly excellent in aesthetics.

  A resin foam having cushioning properties is inexpensive when formed by foaming any one of ethylene vinyl acetate polymer (EVA), latex (LATEX) and styrene butadiene rubber (SBR) or a mixture of two or more. In addition, the cushioning property is particularly good.

  If the upper (shoe table), which is the part where the instep hits, is a strap with both ends connected to one side edge and the other side edge of the insole, the insole can be seen well from the outside, so the design is fully demonstrated. Is done.

  A shoe that uses a structure that puts your feet directly on the insole without using an insole, and uses a resin foam that has cushioning properties in areas where the weight of the insole is particularly heavy. Can be provided at low cost.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the high heel sandal 1 according to the embodiment includes a sole 10 on which a sole is placed and a strap 20 made of a synthetic leather that holds an instep.
An imitation flower 21 serving as a decoration is attached to the strap 20.

  The sole 10 has a double structure including an upper insole 11 on which a sole is directly placed and a lower outsole 12 in direct contact with the ground. The outsole 12 includes a rubber bottom portion, It consists of a hard plastic heel that lifts the heel.

Further, as shown in FIGS. 1 and 2, the insole 11 includes an insole main body 11a, a heel placement portion 11b, an arch placement portion 11c, and a metatarsal bone placement portion 11d.
The insole main body 11a which forms most of the insole 11 is made of ume leather, which is a genuine leather tanned with tannin having a unique luster and hue.
Here, in the case of the high heel sandals 1, the insole 11 is exposed, and the state of the insole 11 greatly affects the overall design. It looks very nice.
Nume leather is relatively hard, so it has excellent durability and shape retention, and when the high heel sandals 1 are worn, the soles are firmly held and hardly wobbled during walking.

Further, as shown in FIGS. 2 and 3, the heel portion, the arch portion, and the metatarsal portion of the leather that forms the insole main body 11a are hollowed out, and a cushion material is fitted in each of the pads. The outer surface is covered, and a heel placement portion 11b, an arch placement portion 11c, and a metatarsal placement portion 11d are formed.
In this way, cushioning is applied to the part of the foot where the weight is applied so as to absorb the impact during walking, so that the high heel sandal 1 is comfortable to wear and does not get tired even when walking for a long time. Yes.

  Here, as shown in FIG. 3, the heel placement portion 11b is formed to be substantially flat, and is substantially flush with the surface of the insole body 11a.

Further, as shown in FIG. 3, the arch placing portion 11c rises from the surface of the insole body 11a along the longitudinal arch of the sole so that the outer edge of the high heel sandal 1 is arcuate in the length direction. ing.
By doing in this way, when the high heel sandal 1 is put on, the vertical arch of the foot is supported in a natural state, so that a feeling of fitting is increased and flat feet are prevented.

As shown in FIG. 3, the metatarsal bone placing portion 11d includes a flat portion 11e and a bulging portion 11f.
The flat part 11e is substantially flat and is substantially flush with the surface of the insole body 11a.
The bulging portion 11f swells from the surface of the insole body 11a along the lateral arch of the sole so that the outer edge is arcuate in the width direction of the high heel sandal 1.
By doing in this way, when the high heel sandals 1 are worn, the lateral arch of the foot is supported in a natural state, so that the fit is increased and the hallux valgus is prevented.

Here, a synthetic leather that is resistant to dirt and wear is used for the pad that directly touches the sole.
Further, as the cushion material, a material having a good cushioning property is appropriately selected and used according to each part.
For example, the arch placement part 11c is particularly expensive, and a foam of a mixture of latex and styrene butadiene rubber, which is somewhat expensive but more excellent in cushioning, is used because it requires a particularly heavy weight and particularly requires cushioning. .
On the other hand, for the heel placement portion 11b, an ethylene vinyl acetate polymer foam is used which is less expensive but slightly inferior in cushioning because it does not take as much weight as the arch placement portion 11c.
For the same reason, a foam of ethylene vinyl acetate polymer is used for the flat portion 11e of the metatarsal bone mounting portion 11d, and a foam of a mixture of latex and styrene butadiene rubber is used for the bulging portion 11f. .

  In this embodiment, the upper is the strap 20, the sole 10 is the high heel, and the cushion shoe according to the invention is the high heel sandal 1. However, the present invention is not limited to this, and sneakers, boots and the like may be used.
