The plane form and the size of the part 11 are properly selected by the form of the lower tip surface of the inside ball of the foot and not limited in particular but the shape is normally circular or horizontally long egg-like or elliptic and the diameter (or longer diameter) is normally 30 mm to 45 mm.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved shoe insole structure.

[0002]

2. Description of the Related Art An insole is provided on the upper surface of the sole of a shoe,
It plays the role of a platform that supports the foot directly on the sole. The upper surface of the insole is usually flat, but the heel is spoon-shaped, the sponge is attached around the heel, and the edge is raised. Also known are those having a cushion function.

[0003] On the other hand, a condition of a good shoe is that the foot does not shift back and forth and right and left inside the shoe. Misalignment causes hammer toe, octopus at upper toe, and beans. In order to prevent slippage, measures such as changing the shoe type to a string type or increasing the compression force of the upper rubber for the slip-on type have been taken, but satisfactory results have not yet been obtained. Not.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a shoe in which a foot is prevented from shifting forward, backward, left and right.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a shoe having an insole provided on an upper surface of an outsole.
A concave portion is provided on a surface portion corresponding to the metatarsal contact portion. The present invention also relates to the above-mentioned shoe, wherein the vicinity of the middle part between the first phalange and the second phalange is the apex, and the fifth phalange from the middle part of the first phalange ahead of the metatarsal point on the crisp side to the middle part of the metatarsal point on the heel side. A step is provided in a portion of the insole corresponding to a substantially “heavy” shape line reaching the middle part of the phalange, and the entire front portion of the “heavy” shape is a lower portion. In this specification, the term "insole" means an insole and / or an insole provided on the upper surface of the outsole of the shoe, and in this case, the insole includes a bottom (midsole).

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS By providing a concave portion on the surface of the insole corresponding to the first metatarsal contact portion, the foot can be stably supported, and the inside of the shoe is prevented from shifting in the front-rear and left-right directions. can do. In addition, the whole part corresponding to the part from the mid-phalange to the toe of the insole is made the lower part, so that the five toes fit in the lower part, so that you can feel free of pressure and feel like a barefoot Can be refracted.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a shoe having an insole structure according to the present invention. In the following description, leather shoes are taken as an example, but the present invention is not limited to leather shoes, but is also applied to cloth and plastic shoes, and is applied to various shoes for sports, commuting to school, leisure, etc. . Reference numeral 4 denotes the outsole, which is made of a known material such as a synthetic resin such as urethane in addition to natural leather. The insole 1 is provided on the upper surface of the outsole 4. In this example, the insole 1 includes an insole 3 and an insole 2. The insole 3 is formed of a known material such as cork, leather board and pulp board in addition to natural leather, while the insole 2 is formed of a sheet of a known material such as natural leather and synthetic leather. Can be printed and affixed. Reference numeral 5 denotes an upper formed of a known material such as natural leather or synthetic leather.

FIG. 2 is a bottom view of the insole 1 of the shoe according to the present invention, in which the outline of the foot placed on the insole 1 and the bone of the foot are schematically shown. Insole 1 is first
The surface of the metatarsal A1 corresponding to the ground contact portion (the lower end surface of the inside ball) has a concave portion 11. The depth of the recess 11 is appropriately selected depending on the size of the foot, the type of shoe, and the like.
Usually 1 mm to 10 mm, preferably 2 mm to 6 m
m, more preferably 3 mm to 5 mm. Recess 11
The planar shape and size of the foot are appropriately selected depending on the shape of the lower end surface of the inside ball of the foot, and are not particularly limited.
Circular or oval or elliptical in the lateral direction,
The diameter (or long diameter) is usually 30 mm to 45 mm.

In this example, as shown in FIG. 2, the vicinity of the middle part between the first phalange B1 and the second phalange B2 is set as the apex, and A step is provided in a portion of the insole 1 corresponding to a substantially "he" -shaped line extending from the toe to the middle part of the fifth phalange B5 in front of the metatarsal point D on the sole side, so that the entire "heavy" front part 12 is formed. Is the lower part. As a result, each toe can bend and stretch without being stressed because it is located in this lowered front portion.

Next, the assembly of the insole will be described with reference to FIGS. In FIG. 3, the upper surface of the insole 3 lacking the front part and having the opening 31 is formed by a flexible insole 2 having a conventional structure so that the peripheral edge 21 wraps the side surface of the insole 3 and the opening 31 of the insole 3 Cover and paste so that the insole 2 is depressed inside. FIG. 4 and FIG. 5 are a bottom view and a top view of the insole 1 thus configured by being bonded together. The concave portion 11 is formed at a portion corresponding to the opening 31 of the midsole 3, and the low portion 12 is formed at a portion corresponding to the front missing portion of the midsole 3. FIG. 6 shows V in FIG.
FIG. 6 is a cross-sectional view of the insole along I-VI, showing a state in which the insole is adhesively fixed on the outsole and a foot is placed thereon for easy understanding. According to the illustrated embodiment, the recess 1
Reference numeral 1 denotes a structure in which a flexible insole 2 is immersed in an opening 31 in the insole, and the insole 2 also functions as a cushion.
The depth of the concave portion 11 (the concave depth of the insole 2) is 7
It is better to be around 0%.

The above-mentioned insole structure can be variously modified. For example, although the thing which lacked the front part was used as the midsole 3, you may use the thing which is flat over the whole bottom. In this case, the front lower part 12 is not formed. Further, although the opening 31 is provided in the insole 3, an opening may be provided in a location corresponding to the insole 2. Alternatively, the concave portion 11 may be formed by providing an opening only in the insole 2 instead of providing the opening 31 in the insole 3. In any case, it is preferable to adjust the shape of the opening such that the peripheral edge and the bottom surface of the concave portion 11 draw a gentle curve.

[0012]

As described above, since the shift in the front, rear, left and right directions inside the shoe can be prevented, a stable walking can be achieved, and the hammer toe, the octopus and the bean on the upper part of the toes can be prevented. This effect is further enhanced when five fingers can freely bend. In particular, in the case of shoes with high heels, the effect of the present invention is remarkable.
