The footwear includes: an upper foot fixing section (1) for covering and fixing an upper portion of a foot; and a foot supporting section attached to the upper foot fixing section for supporting a lower portion of the foot. The foot supporting section includes a resilient mat (2) having a soft elastic body, which can be deformed according to the shape of the foot. The footwear has a simple structure and can give a feeling of walking barefoot on a sponge mat or on a lawn like a soft carpet to provide complete comfort to the wearer during walking.

Description

  The present invention relates to a functional footwear based on a new concept. Such footwear conforms to the shape of a foot and gives a soft touch when walking.

Examples of common footwear are shoes and socks.
Various general shoe structures have been developed depending on the application. A typical shoe includes an upper portion for covering a toe of the foot and maintaining the appearance and shape of the shoe, and a sole. On the shoe sole, an outsole in contact with the ground, a midsole disposed between the outsole and the texion, and an insole for hiding unnecessary threads, tacks, and nails are sequentially stacked. . The texion is formed of a hard material in order to maintain the appearance of the shoe and function as a connecting portion between the upper portion and the shoe sole.

A typical sock, particularly a short sock up to the ankle, includes an upper part covering the toes of the foot and a bottom part surrounding the sole.
As for the feel when walking, by inserting an elastic body between the texion and the outsole or by forming a midsole from elastic material, to absorb the impact due to the weight of the wearer during walking or exercise Shoes have been proposed. However, in conventional shoe constructions, texions cannot be formed from a soft or elastic material, functioning as a connection between the top and bottom of the shoe, maintaining the shape of the shoe, and even midsole and mids In order to fix the elastic body inserted into the sole, it was possible to form only from a hard material. Therefore, in terms of the feeling during walking, there is a limit to obtaining a sufficiently soft feeling that the shoe can adapt to the shape of the foot.

  In conventional shoes, the problems associated with hard texions have generally been compensated by using insoles. However, even in such a case, since the shoe has a hard texion at the lower part of the insole, there is a limit in obtaining a sufficiently soft feel in terms of the feel during walking.

  In the case of socks up to the ankle, efforts have been made to reduce partial impact and improve the feeling of wearing by using double woven fibers at the bottom. However, socks have a function of wearing shoes, and there is a limit in obtaining a sufficiently soft feel that allows the shoe to be adapted to the shape of the foot with respect to the feel during walking.

  For functional shoes that are used for orthopedic purposes such as shape correction, improvement or prevention of muscle and skeletal problems, assisting in rehabilitation, and strengthening certain muscles, such as for functional shoes. It is generally achieved by the shoes of the insole.

Furthermore, Patent Literature 1 and Patent Literature 2 disclose functional shoes used for orthopedic purposes and exercise of a predetermined part of the human body.
In these patent documents, a shape including a hard-soft transition portion is formed between the foot and the ground. As a result, depending on the desired type during walking, the rolling process is forced, or other loads are applied to certain muscles during walking, so such shoes are required for the wearer. Corresponds to the purpose of

  Furthermore, although the above shoes have the purpose of simulating the feel when walking on non-flat surfaces such as sand, forest soil, and pasture, for example, asphalt roads, concrete, flat bottoms, etc. Used on flat surfaces.

  However, since the above functional shoes include a hard texion, that is, another hard structure for maintaining the appearance of the shoe, in terms of feel when walking, it is sufficient that the shoe can adapt to the shape of the foot. there is still a limit to get a soft feel.

  In addition, functional shoes function as a forced treatment that asks the wearer for a predetermined walking method and a predetermined posture, so that the wearer maintains balance using the necessary moving organs such as muscles and skeletons. Must. The adjustment of the walking method and the walking posture is determined by using a hard or soft insertion material having a bottom structure with a predetermined shape. The orthopedic surgeon carefully determines how the wearer behaves and what posture the wearer should take, thereby determining the predetermined shape of the bottom structure.

However, the predetermined shape of the bottom structure may not be suitable for each symptom, and there is a risk that an incorrect posture may be required for a long time due to an inappropriate diagnosis of the orthopedic surgeon.
In conventional shoes used for several functions, in order to obtain an excellent effect on the walking method of each person, orthopedic purpose and movement of a predetermined part, the shoes are attached to the structure of each moving organ. Often needs to be adapted. However, in general, if the wearer chooses the wrong structure or the orthopedic surgeon makes an incorrect diagnosis, functional shoes are not comfortable when worn for the first time, are difficult to wear, and in the worst case Is inconvenient. This situation occurs when the wearer needs to match the shoe.

Not only does the wearer fit the shoe, but the shoe is also adapted to the shape of the wearer's foot and the walking method of the wearer wearing shoes or texions made from leather or cloth by a simple method.
However, although fibers, plastics, and rubber have been recently used as synthetic materials, there are basically limits to adapting a soft material to the wearer's foot due to the characteristics and structure of the shoe described above.

  It has also been researched and empirically proved that comforting the wearer's foot and allowing the maximum degree of freedom has an orthopedic therapeutic effect by the wearer's movement sequence. This has the risk of reporting that rural people walking barefoot on soft natural ground keep their mobile organs much healthier than urban residents wearing standardized shoes.

Therefore, it can fit the wearer and provide perfect comfort while walking, and gives the foot maximum freedom even if part or all of the structure to maintain the appearance of the footwear is discarded There is a need to develop footwear with new concepts that can be done.
European Patent No. 0999964 EP 1124462

  Accordingly, the present invention has been made to solve the above-described problems caused in the prior art, and an object of the present invention is a lawn such as a sponge mat or a soft carpet having a simple structure. It is an object of the present invention to provide footwear that can give a wearer a perfect comfort when walking, by giving a feeling as if he is walking barefoot.

Another object of the present invention is to provide footwear capable of easily changing the comfort and correction function during walking as required.
Another object of the present invention is to provide footwear that gives the wearer perfect comfort while walking and gives the foot maximum freedom.

  To achieve such an object, footwear comprising an upper foot fixing part for covering and fixing the upper part of the foot, and a foot support part attached to the upper foot fixing part for supporting the lower part of the foot. Is provided. The foot support portion includes a resilient mat having a soft elastic body that can be deformed according to the shape of the foot.

  While conventional shoes have a hard texture, i.e., a hard structure to maintain the appearance of the shoe, the present invention provides a hard texture, i.e., the appearance of the shoe to improve the feel during walking. Does not include other structures to maintain.

  In the present invention, although the mode for maintaining the appearance of the shoes is partially abandoned, it has a relatively simple structure and is on a lawn such as a sponge mat or a soft carpet. Not only gives the wearer the feeling of walking barefoot, giving the wearer the perfect comfort when walking, but also by matching the contact area with the shape of the sole of the foot, A degree of freedom can be given.

Preferably, the foot support portion further comprises a shroud that covers a part or the whole of the outer surface of the flexible elastic mat and fixes the elastic mat.
In construction, a resilient mat formed from an elastic body can be protected, easily stored and secured, and a resilient mat (an elastic body received in the chamber when the shroud forms a chamber) is replaceable. Yes, the appearance of the footwear with the upper foot fixing part and the shroud maintains its original shape.

  Preferably, the foot support portion includes a bottom formed on the outer surface of the shroud to prevent slide movement of the footwear when the footwear contacts the ground. This bottom part is formed integrally with the shroud by forming the ground contact part of the shroud thicker than the other parts, or is formed separately and then joined. The bottom portion can also be formed by coating at least a part of the ground contact portion of the shroud.

Preferably, a portion for inserting and retrieving the resilient mat is formed on the surface of the shroud.
With this configuration, it is possible to easily insert and recover only the elastic mat without separating the foot support portion from the upper foot fixing portion.

More preferably, the foot support part can be attached to the foot fixing part by detachably attaching the shroud to the foot fixing part.
With such a configuration, the foot support portion can be attached to the foot support portion in various ways without being limited by the type and shape of the elastic mat, by simply deforming the shroud and the upper foot fixing portion to form the engaging portion. Can be attached to a fixed part. The foot support portion can then be attached or removed and the resilient mat in the shroud can be replaced as needed. Attaching the shroud to the elastic mat is not limited to being detachably attached to the above-mentioned foot fixing portion, and the shroud may be formed integrally with the elastic mat or formed separately. And may be firmly attached to the elastic mat by bonding or the like.

  Further, as noted above, the shroud may have a portion that can be opened and closed and used to insert and retrieve the resilient mat, replacing the resilient mat without separating the entire shroud from the upper foot securing portion. can do.

Preferably, the shroud includes at least one chamber for receiving the elastic body.
Therefore, by accommodating a plurality of elastic bodies having different elasticity in the chamber, such an elastic body gives a feel desired by the wearer during walking, and is further exchanged according to the contact portion of the foot. The elasticity can be easily changed.

Preferably, the resilient mat is divided into a plurality of sections, each section comprising an elastic body.
With such a configuration, the shape and / or material of the sections can be adjusted to change the wearing feeling and the correction function during walking according to the wearer's request.
Further, the elastic body may be an open elastic body, a closed elastic body, or both.

  Here, the open elastic body means, for example, an elastic body made of foamed material or foam structure formed from sponge, rubber, or natural / synthetic resin containing air in its inside or structure, and is elastic by applying pressure. Air is exhausted by pressing the body, and air is reabsorbed by reducing pressure.

  When forming a resilient mat that includes an open elastic body, compressing the elastic body allows air in the interior space of the material or structure to move into the upper foot anchoring section, and the wearer's foot can compress air. In addition, the air flow generated at the time of expansion becomes a ventilation state, and the elastic body can provide a soft touch when walking.

  The closed elastic body refers to an elastic body having a shape of a closed bag filled with a filling material such as air, fluid, gel, or rubber, for example. It can be varied by applying, but no air or filling material is introduced or exhausted. Since a valve (not shown) is formed in the bag-like filling body, the elasticity can be changed by discharging or refilling the filling material inside as needed.

Preferably, the resilient mat is divided into an upper part including at least one open elastic body and a lower part including a closed elastic body.
Due to such a double structure of the elastic mat, the lower part provides a relatively stable elasticity, and the upper part uses an open elastic body, and the air generated by the elastic mat relaxing and contracting causes the footwear during walking. Breathability can be improved.

More preferably, the elastic body forming the elastic mat includes hard elastic particles inside.
With this configuration, the elastic particles inside the soft elastic body reduce the phenomenon that the soft elastic body is abruptly pressed when footwear is worn, and the soft ground feels hard when the soft elastic body is most compressed. It can function as a buffer that prevents it from reaching the foot. Furthermore, the feeling when wearing footwear and the feeling when walking can be adjusted by changing the number, size, and type of hard elastic particles inserted when manufacturing the elastic body. And adjust the maximum compression thickness.

Preferably, the present invention comprises a bottom attached to the outer surface of the foot support portion to protect the foot support portion including the resilient mat and prevent sliding movement when in contact with the ground.
The bottom portion is formed only at the ground contact portion, but is not limited to this. The bottom further covers and extends to at least one of the front, back, right and left sides of the foot to further engage the foot support portion with the upper foot fixing portion, or to further secure a part or the whole of the foot Extend.

  The upper foot fixing portion is formed of a soft material and has a sock shape. Soft materials include natural or synthetic fibers, as in normal socks, and any material that is flexible enough to attach and detach footwear such as natural or synthetic latex or synthetic resin.

Since the upper foot fixing portion has a general sock shape, the upper foot fixing portion can be easily attached and detached, and the wearing feeling and the soft feeling during walking can be maximized as compared with conventional shoes.
Preferably, the upper foot fixing portion has a sock shape made of a textile material and is attached to the shroud at the upper end portion of the foot and is integrally formed with the shroud. In this case, the shroud can be attached by various methods such as sewing and adhesion. In particular, if the material of the shroud is the same as the material of the upper foot fixing part, the shroud may be formed integrally with the upper foot fixing part by weaving, or may be separately manufactured and then accommodated at the lower end. It may be attached to the upper foot fixing part by stitching or the like so as to have a double sock shape.

  More preferably, a portion of the engaging portion between the upper foot fixing portion and the shroud may be openable and closable in order to collect and replace the resilient mat. Furthermore, the shape of the upper foot fixing portion is not limited to the shape of the socks, and can be adapted to different shapes such as shoes and sandals.

  The above as well as other objects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

Reference will now be made in detail to the presently preferred embodiments, examples of which are illustrated in the accompanying drawings. The same elements are denoted by the same reference numerals in the drawings.
FIG. 1 is a view showing a preferred embodiment of the footwear of the present invention. Basically, the footwear of the present invention comprises an upper foot fixing part 1 for covering and fixing the upper part of the foot, and a foot supporting part for supporting the lower part of the foot attached to the upper foot fixing part. Prepare. In a preferred embodiment, the foot support portion is formed of a soft elastic mat 2 that can be deformed according to the shape of the sole of the foot, and is formed integrally with the elastic mat 2 or fixed to the elastic mat 2 to fix the elastic mat 2. A shroud 3 attached separately and a bottom (not shown) formed on a contact surface with the ground to prevent the sliding movement of the footwear.

  As can be seen in this preferred embodiment, the present invention does not include hard texions or other parts for maintaining the appearance of footwear, unlike ordinary shoes, so that the feel of the elastic mat 2 is not walking. It is transmitted to the foot, so the wearer feels comfortable walking barefoot on a soft sponge, carpet or lawn.

  Furthermore, a bottom portion (not shown) for preventing the sliding motion of the contact surface with the ground of the foot support portion can be selectively formed. The bottom portion can be omitted if not necessary depending on the material and shape of the elastic mat 2 or the place where the footwear is used. When the bottom is omitted, only the resilient mat 2 forms the foot support part. Further, when the shroud 3 is used for footwear, the bottom portion can be formed integrally with the shroud when the shroud is formed, or the bottom portion can be attached to the contact surface of the shroud with the ground.

  In addition, as will be described below, the bottom (not shown) can extend upward to secure the foot support part to the upper foot fixation part or to fix the foot to the footwear during walking. It is.

  In the preferred embodiment, the resilient mat 2 is attached to the upper foot by one of the well-known engagement methods such as adhesive bonding, stitching, Velcro ™ fastener, slide fastener (ie, zipper) or snap fastener engagement. You may fix to a fixed part. When the shroud 3 is used for a resilient mat, it is also possible to attach the resilient mat 2 using the engaging portion of the shroud 3 by a known method. Further, in some cases, the bottom (not shown) may be extended and attached.

  The upper foot fixing portion 1 is made of a soft material, and can take various shapes such as socks, rubber boots, sports shoes, sandals, slippers, etc., depending on the application. The material of the upper foot fixing part 1 can also include different materials such as soft rubber, woven fabric, mesh fabric (net), leather and the like.

Further, a plurality of ventilation holes can be formed in the upper foot fixing portion, and the design of the foot fixing portion can be changed by forming a transparent window, for example.
The elastic mat 2 is formed of a soft elastic body or includes a shroud. The elastic material is classified into an open elastic body and a closed elastic body. The open elastic body is, for example, a sponge containing air in its inside or structure, or a foamed material or foam formed from a natural resin / synthetic resin. It refers to an elastic body made of a structure, which discharges air by applying pressure or pressing the elastic body, and reabsorbs air by decreasing the pressure. The closed elastic body refers to an elastic body having a shape of a closed bag filled with a filling material such as air, fluid, gel, or rubber, for example. It can be varied by applying, but no air or filling material is introduced or exhausted. In various embodiments of the resilient mat 2, one or both of such elastic bodies can be used.

The material and structure of the soft elastic body is selected so that the compression ratio of the elastic mat is 50% to 90% when the footwear is worn.
Moreover, since a valve (not shown) is formed in the bag-like closure elastic body, the elasticity can be changed by discharging or refilling the internal filling material as necessary.

  The planar shape of the elastic mat 2 substantially follows the shape of the bottom surface of the footwear. The thickness of the elastic mat 2 (the thickness of the elastic mat itself when the bottom is not formed) is changed depending on the weight of the wearer and the elasticity of the elastic body. As described above, the soft elastic body of the present invention has a compression rate of 50% to 90% when the footwear is worn. Therefore, according to the present invention, it is desirable that the thickness of the elastic body is at least 1 cm from the contact surface with the ground, and at least 0.5 cm for children.

  The shroud 3 is made of the same material as that of the upper foot fixing portion, or is made of a material different from that of the upper foot fixing portion. The shroud 3 can be formed from a soft elastic material, and it is also possible to use different materials such as synthetic or natural fiber material, synthetic or natural latex, polyurethane and the like.

FIG. 2 is a perspective view showing the configuration of another preferred embodiment of the present invention.
In the preferred embodiment of FIG. 2, the basic technical spirit is the same as that of the preferred embodiment of FIG.
The footwear in the preferred embodiment has the shape of a typical shoe or athletic shoe. The elastic mat that forms the foot support portion has the shape of a sole of a general shoe or athletic shoe in a state where pressure before wearing the footwear is not applied. Moreover, when pressure is applied while wearing footwear, the compression ratio of the footwear becomes 50% to 90%, so that the shape of the footwear is deformed.

The upper foot fixing portion 1 has a general shape of an athletic shoe. The material of the upper foot fixing part 1 includes different materials such as soft rubber, woven fabric, mesh woven fabric, and leather.
FIG. 3 is a perspective view showing a configuration of another preferred embodiment of the present invention, and shows a case where the shape of the sandal is applied to the upper foot fixing portion 1. Since the basic technical spirit of the preferred embodiment of FIG. 3 is the same as that of the preferred embodiment of FIG. 1, repeated description will be omitted.

  The upper foot fixing part 1 forming the shape of the sandal may be attached to the foot support part by different methods such as joining and sewing. The elastic mat 2 forming the foot supporting portion has a sole shape of a general shoe or athletic shoe in a state where pressure before wearing the footwear is not applied.

  When the shroud is used for footwear, the elastic mat 2 is firmly fixed to the surface of the shroud. The upper foot fixing part 1 having the shape of a sandal and the elastic mat 2 forming the foot support part can be exchanged as necessary and are detachably attached to each other.

FIG. 4a is a perspective view showing the configuration of another preferred embodiment of the present invention, showing a preferred example in which the technical spirit of the present invention is applied to a sock form.
FIG. 4 b is a view showing a method for exchanging the elastic mat 2.
In a preferred embodiment, the upper foot fixing part 1 and the foot support part form a sock shape in appearance. Since the receiving space for accommodating the elastic mat 2 is formed between the upper foot fixing portion 1 and the foot support portion, the elastic mat 2 is accommodated in the receiving space.

  In a preferred embodiment, the upper foot anchoring portion is formed from a synthetic or natural fiber material, and may be formed from a soft rubber if desired. The upper foot fixing portion and the foot supporting portion are formed integrally or are formed separately and attached to each other by stitching.

  Furthermore, a part or the whole of the upper foot fixing part and the foot supporting part can be detachably attached by an engaging tool such as a Velcro (trademark) fastener, a slide fastener (zipper) or a snap fastener. When the foot fixing portion and the foot support portion are separated, the elastic mat 2 can be inserted or recovered. In the preferred embodiment, the entire footwear is attached by stitching and the slide fastener is attached to the heel portion of the foot so that when the slide fastener is opened as shown in FIG. 4b, the resilient mat 2 is inserted into the receiving space or It can be recovered from the receiving space.

  5a to 5f are views for explaining the engaging structure of the upper foot fixing portion and the foot supporting portion according to the present invention. In a preferred embodiment of the invention, the foot support part covers a part of the outer surface of the soft elastic mat 2 and further comprises a shroud 3 for receiving and fixing the soft elastic mat 2. In this case, the upper foot fixing portion and the foot support portion are attached to each other from a part of the shroud 3. The shroud 3 can be formed integrally with or separately from the resilient mat 2.

For reference, in the engaging structure, the engaging portion is shown as an extended portion of the shroud 3, but may be an extended portion of the bottom portion (not shown).
In the present specification, the engagement structure of the upper foot fixing portion and the foot support portion will be described in detail with reference to the drawings.

  In FIG. 5a, the shroud 3 of the elastic mat of the foot support part is fixed and attached to the foot fixing part by bonding or stitching in order to attach the foot support part including the elastic mat to the foot fixing part. By inserting and retrieving the resilient mat without separating the entire shroud from the upper foot securing portion, a portion that can be opened and closed to replace the resilient mat is formed on the outer surface of the shroud 3.

  In the preferred embodiment of the present invention, the portion that can be opened and closed by using the slide fastener 4 is formed in the heel portion of the shroud 3, but can be attached to any surface depending on the use or design of the footwear.

  In the preferred embodiment, the use of such an openable and closable portion protects the resilient mat 2 formed from an elastic body and, in addition, can be easily accommodated and fixed. Furthermore, it is possible to replace only the elastic mat, but the appearance of the footwear maintains its original shape.

  FIG. 5b shows the foot support part being removably attached in the form of an overshoe by extending the upper part of the shroud 3 of the foot support part to cover and fix the tip of the foot support part. .

  In a preferred embodiment, the upper foot fixation portion can be separated from the foot support portion by removing the shroud in the form of an overshoe. During the separation, the elastic mat 2 can be replaced, and only the foot support portion can be replaced with another one or washed.

FIG. 5 c is a cross-sectional view showing a state in which the shroud 3 extends from the toe of the foot to be fixed to the ankle portion and the foot support portion is fixed in the form of a double sock.
In a preferred embodiment, the upper foot anchoring portion can be separated from the foot support portion by removing the shroud from the upper foot anchoring portion, as in the form of overshoes. In addition, the elastic mat 2 can be replaced at the time of separation, and only the upper foot fixing portion can be replaced with another one or washed.

Further, in such a case, as shown in the figure, a space for ventilation can be formed in the heel portion of the foot.
FIG. 5d shows a configuration in which the foot support portion is secured in the form of a double sock by extending the shroud over the toes of the foot to the ankle portion at the front of the foot to secure the shroud. The rear part of the shroud extends to the heel part of the foot and is attached by stitching. In such a configuration, the elastic mat 2 can be exchanged by attaching a slide fastener at the rear end of the shroud and opening and closing only the flange portion.

This engagement structure is particularly suitable when the foot fixing portion and the foot supporting portion are formed from a fiber material or soft rubber and are shaped like a sock.
In FIG. 5e, the slide fastener 4 is attached to the upper end portion of the shroud 3 as an engaging portion, and the shroud 3 is connected to the slide fastener attached to the lower end portion of the corresponding upper foot fixing portion. It shows the state.

  In this engagement structure, when the slide fastener is opened, the foot support portion is separated, so that the elastic mat 2 can be replaced. In the preferred embodiment, if the shroud is not applied to the resilient mat, the slide fastener 4 is formed on the resilient mat.

In FIG. 5f, the bottom, the upper end of the shroud, or the resilient mat is attached to the upper foot securing part 1 using a Velcro ™ fastener.
In a preferred embodiment, the Velcro ™ fastener 5a is attached only to the upper outer peripheral surface of the foot support portion and connected to the Velcro ™ fastener 5b attached to the lower end of the upper foot fixing portion. Therefore, it is possible to prevent the feeling of wearing of the footwear from being lowered by the engagement with the Velcro (trademark) fastener. In addition, the Velcro ™ fastener portion extends not only to the engagement surfaces of the foot fixing portion and the foot support portion, but also to the periphery of the side surfaces of these portions. The combined state can be strengthened.

In practical embodiments, these two engagement methods can be used separately or together.
6a to 6g are views for explaining a method of forming a foot support portion by the configuration of the elastic mat 2, the shroud 3, and the bottom portion 4 of the present invention.

  FIG. 6 a shows a preferred embodiment including only the resilient mat 2. The elastic mat that is an elastic body may have a portion that functions as a shroud integrally formed on the outer surface in the manufacturing process. In this case, depending on the manufacturing method used, the shroud or the portion functioning as the shroud may be formed of the same material as the elastic body, thereby increasing the mechanical frictional force of the outer surface of the elastic body. The elastic mat can be directly attached to the upper foot fixing portion, or can be used as an insert according to the embodiment. Further, a bottom (not shown) for preventing the sliding movement of the footwear may be selectively formed on the contact surface with the ground.

  When a shroud described later is applied, the shroud may be formed integrally with the elastic mat when the elastic mat is manufactured. When the shroud is manufactured separately, the shroud can be detachably attached to the elastic mat or can be firmly attached to the elastic mat by adhesion or the like.

  FIG. 6b shows a preferred embodiment in which the shroud 3 covers the entire elastic body. In this case, for example, the shroud needs to be made of an essentially soft elastic membrane, or a film material such as thin rubber or elastic fiber. In this preferred embodiment, when manufacturing the shroud, the surface in contact with the ground functions as the bottom by making the contacting surface portion thicker than the other portions.

  FIG. 6c shows the case where the shroud 3 covers only the periphery of the upper surface of the elastic mat in order to minimize the change in the wearing feeling of the footwear. Similarly, when manufacturing the shroud, the surface portion that contacts the ground is formed thicker than the other portions.

  The portion of the shroud covering the resilient mat functions as an engaging portion when the upper foot fixing portion is attached to the shroud by adhesion, stitching, Velcro (trademark) fastener or the like.

  In FIG. 6d, the shroud extends to the upper side of the resilient mat. A connecting portion, such as a slide fastener, a Velcro ™ fastener, or a snap fastener, is attached to the extension portion of the shroud and connected to a corresponding portion of the upper foot securing portion. The shroud may further extend to the upper foot securing portion in the form of overshoes or double socks. Similarly, the surface portion that contacts the ground is formed thicker than the other portions when the shroud is manufactured.

6e-6g, the bottom 6 is formed separately on the contact surface of the shroud with the ground.
Figures 7a and 7b show a preferred embodiment in which the resilient mat has sections.
In FIG. 7a, the resilient mat is divided on the left and right of the foot. In FIG. 7b, the elastic mat is divided into left and right and front and back of the foot, and thus has a matrix shape.

  In this case, the shroud (not shown) may have the same shape as the outer shape of the elastic mat 2 in order to accommodate the elastic mat 2, or may accommodate the elastic mat regardless of the shape of the elastic mat. Is possible.

  Further, in this case, the shroud or the portion functioning as the shroud is formed of the same material as the elastic body, so that it is possible to reinforce the mechanical frictional force on the outer surface of the elastic body according to the manufacturing method. is there. The resilient mat may be directly attached to the upper foot fixing part, or may be used as an insert depending on the embodiment. Further, a bottom (not shown) for preventing the sliding movement of the footwear may be selectively formed on the contact surface with the ground. Furthermore, the wearing feeling and the correction function during walking can be changed according to the wearer's request by adjusting the shape and / or material of the elastic mat section.

  FIGS. 8 a and 8 b show the configuration of the shroud 3, and the elastic mat is manufactured by inserting an elastic body into a chamber formed in the divided shroud 3. The shroud forms a plurality of chambers for receiving elastic bodies, and the elastic mat 2 is formed by inserting the plurality of elastic bodies into the chambers. In this case, a shroud cover (not shown) covering the open portion of the elastic mat is selectively used. If a shroud cover is used, the shroud cover is formed from a soft and breathable material.

9 and 10 are diagrams for explaining the compression ratio before and after inserting the insert into the elastic body of the elastic mat when wearing the footwear.
For example, when the elastic mat body is formed of a foamed material made of a synthetic resin such as polyurethane, the elastic body including the insertion material inserts polyurethane particles or granules in the foaming process for creating the shape of the foamed material. It is possible to manufacture. Furthermore, in the case of a closed elastic body that fills a bag with fluid or gel, elastic particles such as polyurethane granules can be added before filling the bag with fluid or gel.

  FIG. 9c shows a change in the difference Δd between the thickness d1 of the elastic mat before wearing the footwear and the thickness d2 of the elastic mat after wearing the footwear when a general elastic body is applied to the elastic mat. 5 is a graph showing a resilient repulsive force F as a function of.

  FIG. 10c shows the thickness d1 of the elastic mat before wearing the footwear and the thickness of the elastic mat after wearing the footwear when granules harder than a general elastic body are inserted into the inside of the elastic mat. It is a graph which shows the elastic repulsive force F as a function of the change of difference (DELTA) d with d2.

FIG. 9a shows that the elastic repulsion changes to near the elastic mat critical thickness d1 in a given line shape.
On the other hand, the elastic mat shown in FIG. 10a includes granules that are harder than the elastic material, and the elastic repulsion curve can be adjusted according to the number and type of granules as shown in the graph. is there.

Although the drawings show only a cross section for convenience, the present invention is applied to an elastic body that forms elastic mats having various shapes.
The footwear according to the present invention has a simple structure and gives a feeling of walking barefoot on a lawn such as a sponge mat or a soft carpet, so that it is perfect for the wearer during walking. Can be provided.

Moreover, this invention can change a feeling of wear and a correction | amendment function easily at the time of a walk as needed.
Furthermore, the present invention can provide the wearer with a perfect comfort while walking and can give the maximum degree of freedom to the foot.
