Description

Structurally improved footwear

The present invention relates to an article of footwear, such as a shoe or the like. Footwear can be used in hiking, flat or mountain racing, skateboarding, ball sports, cross-country skiing, snowboarding, snowshoeing, bicycles and more.

Footwear products need to meet a variety of functions, sometimes contradictory between functions, such as maintaining foot support and / or sufficient tightness, while providing satisfactory comfort. At the same time, the footwear must have a certain degree of softness. The good softness makes the shoe still able to stick to the foot when the foot is deformed. In other words, the footwear must be in close contact with the foot so that the person can move freely while walking or performing sports activities.

For known ways of making an article of footwear, such as by stitching the upper and the sole to make the shoe. The upper generally comprises a plurality of components: the outer side of the shoe, the inner side of the shoe, the upper, the tongue, the heel, the heel, the front protective toe cap, the elastic mechanism including the lace holes and the laces, the inner lining and other accessories. In addition to this, some of these components may also include several components. A major problem in making such shoes is the assembly of some planar cutting members or assemblies into a three-dimensional shape. The upper and the insole are combined in a known manner to form a shoe body component. According to the first method, the upper is glued to the inner sole with a layer of adhesive. The insole - also known as the midsole - is relatively hard to withstand the assembly process. The combination is accomplished by pulling the upper to fit on the midsole, a mold is known to be inserted into the shoe. Help. This method is called traditional shoemaking. This technique obtains the shoe body part by applying sufficient pressure while heating the adhesive layer. The second method is also well known in which the upper is joined to the midsole by sewing. This method is called a strobel assembly. The midsole is here a soft sole that is suturable and is referred to as a nested sole. For each of the first and second methods, the midsole forms part of the sole. The sole also includes external components, such as one or more layers of cushioning, and a layer of wear for contact with the ground, typically by gluing the components to the midsole and the formed upper. The sole also includes one or more layers of inner layers disposed within the body member of the shoe for maintaining hygiene, shock absorption, arch cushioning, and other protection functions. Finally, the shoe body member and other members of the sole are combined to form a shoe.

It can be seen that prior art shoes have some drawbacks regardless of the above shoemaking methods. First, making shoes requires a large number of parts, usually consisting of 40 to 60 parts. Since the number of parts for making shoes is very large, the process of making shoes takes a long time. It usually takes 40 minutes to 90 minutes to make a pair of shoes. It can be said that the traditional shoe-making technology is not only very complicated, but also requires a large number of components and cumbersome production steps.

Another drawback stems from the discontinuity in the structure of the shoe, especially in the upper. For example, sometimes a small part is superimposed on another slightly larger part, which can seriously affect the bending ability of the upper at the position where the smaller part is set. Such shoes are not only uncomfortable to wear, but the upper is difficult to form, that is, it is difficult to form a three-dimensional shape.

Another drawback stems from the gaps between the foot and the shoe. This means that in some places the foot does not touch the upper or the sole. Especially in certain parts of the joint between the upper and the midsole. Therefore, it is noted that movement sometimes occurs between the foot and the shoe, and these movements may cause discomfort or trauma. Sometimes still at the feet, ankles or There is a gap between the calf and the upper at the shoe opening. Therefore, foreign objects will inadvertently enter the shoe.

In summary, it can be said that shoes made using the prior art are not guaranteed to be provided to the foot for support and/or sufficient tightening, or to provide satisfactory comfort. In addition, such shoes do not always fit the foot to accommodate all deformation of the foot.

Based on this, the applicant has proposed another method of making an article of footwear.

For example, according to the patent document FR 2 999 881, an article of footwear comprises one or two covering bodies, each covering body extending from the rear end to the front end in length and extending between the outer edge and the inner edge in width. Extending from the bottom end to the top end in height, each of the cladding bodies includes wires that are mechanically interwoven.

The covering body is shaped to have a volume, that is, three-dimensional, by being placed on a mold having a geometry very similar to the shape of the foot, and thus is very close to the foot. That is, the foot and the covering are in contact, or at least very close. This structure results in a small sudden movement between the foot and the covering body, even without movement, so that the foot can be evenly supported. The benefit of such an article of footwear is that it can increase the comfort of the shoe as compared to conventionally made shoes.

It is also noted that, according to the manufacturing process of the patent document FR 2 999 881, each of the covering bodies has a continuous structure in the direction of its inner and/or outer surface, even if it is not completely regular, at least in a substantially regular manner. In this way, the discomfort of the wearer will be reduced, or even uncomfortable.

The above conclusions show that the covering can maintain the shape of the foot and provide satisfactory comfort to the foot. In addition, each of the coverings can also conform to various deformations of the foot. According to the patent document FR 2 999 881, such an article of footwear can maintain comfort even when it is stationary or moving.

Further, according to the manufacturing process of the patent document FR 2 999 881, it is noted that less articles can be used to make an article of footwear.

Based on this, the present invention is directed to further improving footwear products as a whole. More specifically, the present invention is intended to improve, for example, the transmission of steering forces, the reaction forces of the ground or equipment, or the perception of sensory information. The present invention aims to optimize utilization and reduce fatigue of the wearer. The present invention is also directed to meeting the particular needs of a wearer while retaining essential features such as comfort and footing. For example, in the case of sports, when it is necessary to seek support or strong information transmission, this is a real challenge. Indeed, the optimization of comfort and force transmission effects is the opposite concept.

In order to solve the problems previously presented, the present invention provides an article of footwear comprising a first layer of covering body extending from the rear end to the front end in length and at the outer and inner edges in width Extending therebetween, and extending from the bottom to the top in height, the first layer of cladding includes wires that are mechanically interwoven, and the first layer of cladding defines a size for receiving the foot; such footwear The article further includes a second layer of cladding extending from the rear end to the front end in length, extending between the outer edge and the inner edge in width, and extending from the bottom to the top in height The second layer of cladding includes wires that are mechanically interwoven, and the second layer of cladding also defines a size for receiving the foot, the first layer of cladding and the second layer of coating relative to each other Settings.

The article of footwear of the present invention is characterized in that at least at one subdivision, including an insert member elastically deformable in a reversible manner, the insert member is disposed on the first layer of the cladding and the second layer Between the bodies.

This gives one or more specificities to the article of footwear at a certain location Attributes. For example, on the top end of the covering body, as will be explained in detail later, the insert member may be a tongue. Alternatively, at the bottom level, as will be explained in detail later, the insert member may be part of the sole element. In each of the above cases, the insert member allows a portion of the wrapper to move relatively relative to where it is located. Because this allows the embedded component to be reversibly elastically compressed, the embedded component can bring the relevant portions of the cladding closer together, for example, at a particular stress, and then restore the natural spacing. This spacing corresponds to the thickness of the embedded component. When subjected to an external force, the insert member disperses a part of the pressure in all directions except the direction perpendicular thereto, and thus these external forces can be absorbed. In other words, the embedded component enhances the effect of surface force transmission, different impulses or sensory information of the article. This greatly improves the comfort of the shoe. Surprisingly, the transmission, momentum or information of the force has not changed. Thus, the present invention has succeeded in ensuring that the article clarifies its function while maintaining comfort. This improves the performance of the shoe and reduces the fatigue of the wearer.

In summary, it can be said that the present invention improves the structure and method of making an article of footwear.

Other features and advantages of the present invention will be better understood from the following description, taken in conjunction with the accompanying drawings.

The first embodiment to be described is exemplified by an article of footwear for hiking, leveling or mountain running. However, the first embodiment can also be applied to other fields mentioned above.

The first embodiment will be described below with reference to Figs.

As shown in Figures 1 and 2, the article of footwear 1 is intended to accommodate the wearer's foot. It is suitable for the description below, and although the article of footwear 1 is a shoe, it is unusual to see its structure immediately by detail. Thus, the shoe 1 extends in the longitudinal direction L between the rear end or the heel 4 and the front end or the toe 5 in length, extending in the transverse direction W between the outer edge 6 and the inner edge 7 in width.

As shown, the shoe 1 includes a lower portion 10 for wrapping the foot without including any upper. Alternatively, however, it is also contemplated that the shoe includes both a lower portion and an upper that can wrap around the ankle or even the lower leg.

According to the first embodiment described, the shoe 1 is extended in height from the bottom 12 Extends to the top end 13, that is, until the free end of the shoe 1 or lower portion 10. The bottom is the subdivision of the shoe for the foot.

The shoe 1 is configured to allow a person to support and receive transmission of sensory information while walking, and to maintain a smooth walking of the foot when subjected to an impact. This is also the reason why shoe 1 or footwear is relatively soft.

As described in detail below, the shoe 1 comprises a first layer of cladding 21 extending lengthwise from the rear end 24 to the front end 25 in the longitudinal direction L and extending in the transverse direction W between the outer edge 26 and the inner edge 27 in width. Extending from the bottom 28 to the top end 29 in height. This allows the first layer of wrap to wrap and support the wearer's foot. In its constitution, the first layer of cladding includes wires that are mechanically interwoven, which will be explained later. Likewise, for the first layer of cladding, at least a portion of the wire comprises at least one molten fiber, as will also be explained below.

According to a non-limiting first embodiment, the line of the first layer of cladding comprising at least one molten fiber is distributed throughout the first layer of cladding 21, the melting of the wire being more or less depending on the amount and density of the wire. It contributes to the maintenance and/or adhesion and/or wear resistance of the first layer of cladding. In fact, the melting can maintain the first layer of cladding 21 in its own shape. It can be said that, on the one hand, the first layer covering body 21 is a single component, and on the other hand, it can form a self-supporting member, and its shape is more or less imparted to the shoe according to the amount/density of the thread. Therefore, the first layer covering body 21 imparts or contributes to the shape of the shoe 1 . In other words, the rear end 24, the front end 25, the outer edge 26, the inner edge 27, the bottom 28 and the top end 29 of the first layer of cladding define the rear end 4, the front end 5, and the outer edge 6 of the article of footwear or footwear 1, respectively. , the inner edge 7, the bottom 12 and the top end 13. The extremely simple construction of the first layer of cladding 21 ensures simplicity, lightness and other advantages, as will be seen later.

For the purpose of limitation, according to a first embodiment of the invention, the shoe 1 further comprises a second layer covering 31 extending lengthwise from the rear end 34 to the front end 35 along the longitudinal direction L, in the outer edge of the width 36 extends in a lateral direction W between the inner edge 37 and extends from the bottom 38 to the top end 39 in height. Like the first layer of cladding 21, the second layer of cladding 31 also wraps the foot. The second layer covering body 31 is located outside the first layer covering body 21, and thus does not directly wrap the foot. Finally, the shape of the shoe 1 is determined by the combination of the first layer covering body 21 and the second layer covering body 31. The first layer covering body 21 and the second layer covering body 31 are disposed opposite to each other.

According to the gist of the present invention, the second layer covering body 31 includes wires that are mechanically interwoven. Also, for the second layer of cladding, at least a portion of the wire includes at least one molten fiber, which will be explained later. Those lines comprising at least one molten fiber are distributed throughout the second layer of cladding 31, and the melting of the wire contributes more or less to the maintenance and/or adhesion of the second layer of coating depending on the amount and density of the wire. And / or wear resistance. Also, the melting can maintain the second layer covering body 31 in its own shape. It can be said that, on the one hand, the second layer covering body 31 is a single member, and on the other hand, it can form a self-supporting member, and its shape is more or less imparted to the shoe depending on the amount/density of the thread. Therefore, the second layer covering body 31 imparts or contributes to the shape of the shoe 1 . In other words, the rear end 34, the front end 35, the outer edge 36, the inner edge 37, the bottom 38 and the top end 39 of the second layer of cladding 31 also define the rear end 4, front end 5, and outer side of the article of footwear or shoe 1, respectively. Edge 6, inner edge 7, bottom 12 and tip 13. The extremely simple structure employed by the second layer of cladding 31 ensures simplicity, lightness and other advantages, as will be seen later.

In order to further highlight the specific features of the present invention, it is necessary to specify how the first layer of cladding 21 and the second layer of cladding 31 are made. The details will be described below with reference to FIGS. 3 to 7.

First, as seen in the schematic view of Fig. 3, it is shown that each of the covering bodies 21, 31 is formed by forming the sleeve 41, that is, the sleeve is actually obtained by mechanically interlacing the wires. . The sleeve 41 is a semi-finished product for making the article of footwear 1 . By combining the non-limiting first embodiment, the sleeve 41 can simultaneously form the first layer covering body 21 and the second layer covering body 31. The sleeve 41 extends from the first end 42 to the second end 43 in the length direction. The first end 42 herein is stitched by conventional techniques well known to those skilled in the art, such as stitching after folding, adding a top made of mechanically interwoven threads, or the like. The second end 43 is a simple opening.

It has been found that the sleeve 41 can allow the covering bodies 21, 31 to be made in one piece. At this time, the first layer covering body 21 and the second layer covering body 31 are extended to each other. In this way, the production is simplified by reducing the number of parts and reducing the time necessary for installation.

The combination of the wires for forming the sleeve 41, that is, the covering bodies 21 and 31 is as shown in Figs. 5 and 6. In general, it is desirable to mechanically interweave the threads by appropriate textile techniques, such as knitting, weaving, weaving or other techniques. In the case of knitting, it is possible to use a circular single jersey machine or a double jersey machine, a drum loom or a linear loom. Two pieces of woven fabric can be joined together by intarsia techniques or embroidery. Various decorative patterns can be obtained directly in the knitting process by Intarsia, embroidery, Jacquard technology or other means. Figure 5 illustrates a conventional weaving technique in which a first set of lines 44 are oriented in a first direction and a second set of lines 45 are oriented in a second direction, with the first set of lines 44 and the second set of lines 45 intersecting each other to form an elastic mesh. The knitting technique of Fig. 6 is that the three wires 46, 47, 48 are intertwined with each other. Of course, other various patterns can also be applied.

The sleeve 41 is made, for example, of a linear weaving machine that allows changing the cross-section, in fact, the diameter of the sleeve, to obtain different shapes of the heel, openings for the laces and lace holes, and changing the sleeve wall. Density, or especially the tightness of the stitches degree. In fact, linear textile machines offer a wide range of setting options and are suitable for making sleeves of all sizes, regardless of diameter and length. In this regard, linear textile machines are more practical than circular textile machines. In fact, circular textile machines can only work in a small range of sleeve diameters. Therefore, it is necessary to use a plurality of different circular weaving machines in order to make a full range of sleeves 41, that is to say, for all dimensions of the full range of shoes, only one linear weaving machine is sufficient. Finally, the linear textile machine can produce one or more layers of three-dimensional shapes with all the required characteristics and the required dimensions.

In addition, attention should also be paid to the wires used in the present invention.

First, the wire can be a single fiber, for example, extruded from a molten synthetic material such as polyamide, polyurethane, polyethylene or other equivalent or similar material. The production of fibres is continuous, similar to the way silk is spun. Incidentally, the fibers may be a single component, or a single material, the cross section of which is regular. However, the fibers can also be multi-component, such as two components. In the case of two components, the cross section of the fiber shows a core composed of a first material and a sheath encasing the core, and the outer skin is composed of a second material. Each material is meltable or one of them is meltable. If both materials are meltable, the melting temperatures are not the same.

The wire can also be a composite fiber. In this case, it is obtained by twisting several fibers. This twisting is shown in Figure 7. All of the fibers 49 herein are of the same nature, meaning that each fiber has the same melting point. However, it is also possible to provide a combination of fibers of different properties, some of which are meltable, while others are not meltable or have different melting points from each other. The fibers can be twisted to each other by any known technique.

Alternatively, the wire can be realized in the form of a web. This fiber is a finite length of fiber. Fiber by any known technique, in particular, tanning Closely connected to form a net. The fibers are usually held together by friction, in particular, natural fibers, such as cotton. However, for the present invention, the retention between the fibers can be either by friction or by a combination of friction and fusion bonding, or even by all bonding, since the present invention employs a hot melt material.

The general structure of the sleeve 41 is described above, and its use for making the shoe 1 will be described below. However, before that, in order to maintain the gist of the first embodiment, the article of footwear 1 or shoe including the reinforcing member 51 is explained. It can be better seen that the reinforcing member is embedded in the covering bodies 21, 31 when the shoe 1 is made, so that the shoe obtains special properties.

As shown in Figures 1, 2 and 8, the stiffener 51 is a member that extends in length from the rear end 54 to the front end 55 and extends between the outer edge 56 and the inner edge 57 in width, and It extends from the bottom 58 to the top end 59 in height. The length and width of the reinforcing member 51 are similar to those of the covering bodies 21 and 31. More specifically, the stiffener 51 extends relative to the first layer of cladding 21 from the rear end 24 to the front end 25 in length, between the outer edge 26 and the inner edge 27 in width, from the bottom in height 28 extends to the top end 29. Such a structure can reinforce the first layer of cladding 21, thereby reinforcing the article of footwear 1 , particularly at the bottom 12 and around the bottom.

Optionally, the stiffener 51 is provided with a slack mechanism 61. This elastic mechanism includes, for example, a lace hole 62 (located at the top end 59), as well as a lace 63 and a locking mechanism 64 as are known to those skilled in the art. Therefore, the reinforcing member 51 can be tightened or loosened, so that the shoe 1 can be tightened or relaxed, and then will be better presented. The lace aperture 62 represents any mechanism for passing through, adjustable laces. The locking mechanism is optional and can be replaced by a simple shoelace knot.

More specifically, with regard to the first embodiment, the stiffener 51 comprises: a bottom portion 58; at least one outer branch portion 65 extending from the bottom portion in a direction away from the bottom portion thereof a free end 66 having a lace hole 62; at least one inner branch portion 67 extending from the bottom portion away from the bottom portion to a free end 68 thereof, the free end 68 being provided with a lace hole 62 At least one lace 63 passes through the lace holes. Without limitation, the stiffener 51 includes four outer branch portions 65 and four inner branch portions 67. However, these numbers can be different. It will be apparent that each of the branches 65, 67 is provided with a lace hole which can be realized according to techniques well known to those skilled in the art. Finally, the combination of the reinforcing member and the elastic mechanism can uniformly clamp the covering bodies 21, 31, thereby also ensuring the clamping of the foot.

In particular, in order to optimize the comfort of the article of footwear 1, as shown in Figures 1 and 2, the outer branch portion 65 and the inner branch portion 67 are at least partially disposed in the first layer of the cladding 21 and the second layer. Between the bodies 31, and the lace holes 62 are provided outside the first layer covering body 21 and the second layer covering body 31.

According to the invention, it can be understood by means of the elements of Figures 1 to 10 that, at least at the subdivided portion, such an article of footwear comprises an insert member 71 which is resiliently deformable in a reversible manner, the insert member 71 being arranged in a first layer The body 21 is between the second layer covering body 31. As shown, this can generally provide for the two subdivided portions of the cladding bodies 21, 31 to be substantially opposite each other, even if the inlay members partially separate them. The embedded component can be compressed in proportion to the external force when the component is used. When the external force disappears, the embedded component will return to its original thickness. As such, the insert member absorbs a portion of the pressing force applied to itself and then releases a portion of the force toward each direction except for the direction perpendicular thereto. This reduces the unit pressure of the wrap and helps increase comfort.

With regard to the first embodiment, the insert member 71 has a long shape that can be extended with the elastic mechanism/shoe belt to protect the wearer's instep, thus Meaning for the tongue. The tongue 71 is located at the tips 29, 39 of the first layer of cladding 21 and the second layer of cladding 31, the tongue 71 extending in length from the rear end 74 to the front end 75, and in the width at the outer edge 76 and the inside The edges 77 extend between and extend from the lower 78 to the upper surface 79 in thickness. The comfort of the article of footwear is improved by such a top end of the covering body. For the wearer, the upper part of the foot, that is, the instep and/or the foot bend, is better protected.

In this example, the rear end 74 of the tongue is slightly wider and generally forms a T-shape. The tongue can also be a regular rectangle, the main part of which extends under the strap, and has an adjustment function, is lightweight, and is aesthetically pleasing depending on the situation.

The tongue also has other functions than those mentioned above, such as aesthetics. The tongue can also extend only under the lace portion (outside the lace hole) so that the instep can be protected at all times.

In particular, with the aid of Figures 3 and 4, in this embodiment, the rear end 74 of the tongue 71 engages the first layer of cladding 21 and/or the second layer of cladding 31 with the remaining tongue Most of it is detached from the first layer of cladding 21 and/or the second layer of cladding 31. Thus, the rear end 74 of the tongue is at least immovable relative to the wrap, while the remainder of the tongue, i.e., the intermediate portion and the front end 75, are slidable relative to the wrap. This can facilitate longitudinal flexibility of the article of footwear for better movement of the foot. In addition, the joining of the back end can be by any suitable means, such as bonding or other similar or additional techniques. Bonding can be done in any other way.

In an exemplary embodiment, the rear end 74 of the tongue engages the two layers of cladding 21, 31, which results in an aesthetically pleasing appearance.

According to Figures 1 and 2, it can be seen that at least one lace aperture 62 is located above the tongue 71. In fact, according to the first embodiment, but not limiting, all of the lace holes are located above the tongue. This optimizes comfort. Actually, when passed When the elastic mechanism 61 is tightened, the lace hole 62 is pressed against the foot by the tongue provided in the middle. Of course, the elastic system can also be achieved in different ways, such as through the eye of the eye.

In order to achieve its function in the best conditions, the tongue 71 comprises an elastically deformable layer of synthetic material. This material layer can be made of ethylene vinyl acetate foam (EVA), polyurethane foam, polyethylene foam, or any other material capable of achieving the same function. The tongue may comprise a plurality of sections, such as a plurality of layers disposed in a mutually overlapping manner in a suitable manner, and may also comprise a natural material such as cork or the like.

Still not for the purpose of limitation, according to the first embodiment, at least one of the first layer covering body 21 and the second layer covering body 31 is provided at the outer edge 76 and/or the inner edge 77 of the tongue 71. There are pleats 81, 82, 83, 84. Specifically, the first layer covering body 21 has an outer pleating layer 81 and an inner pleating layer 82, and the second layer covering body 31 has an outer pleating layer 83 and an inner pleating layer 84. Due to these pleats, the geometry of the first layer of cladding 21 and the second layer of cladding 31 is varied, thereby changing the volume of the article of footwear. In other words, these pleats are easy to wear and take off, but they hide when the foot is worn into the shoe.

How to use the sleeve 41 to make the shoe 1 will now be described with reference to Figs. 9 and 10. In fact, the assembly of the components of the shoe 1 is done by hand, without the use of complicated and expensive machines as in the prior art.

As shown in Figures 9 and 10, the sleeve 41 is placed over a member 86, referred to as a foot mold, which is formed according to the shape of the wearer's foot. The sleeve is placed over the foot mold 86 in the form of a sock on the foot. Since the sleeve 41 is made of a woven material having elasticity, it conforms to the shape of the foot mold 86. Subsequently, the reinforcing member 51 is embedded in a subdivided portion of the sleeve 41 as the first layer covering body 21. Next, the subdivided portion of the sleeve 41 as the second layer covering body 31 is folded over the reinforcing member 51, and the reinforcing member 51 and the first layer covering body are used. The subdivision is partially covered. Thus, a semi-finished product of the shoe 1 which can cover the foot is formed, which finally comprises the first layer covering body 21, the reinforcing member 51, the second layer covering body 31 and the tongue 71. It should be noted that the second layer covering body 31 has a plurality of holes 87 for passing the free ends 66, 68 on the outer side branching portion 65 and the inner side branching portion 67 of the reinforcing member 51. Through all applicable techniques, the semi-finished product shapes the shoe 1 at a high temperature sufficient for the molten fibers used to melt the cladding. After heating, the foot mold 86 is withdrawn from the semi-finished product. The shoe 1 is basically completed. According to the first embodiment, an additional outer sole 88 is required.

As shown in Figures 1 and 2, the article of footwear 1 or shoe includes an outer sole 88. In addition, the sole is mainly used to support on the ground so that it is constructed to resist frictional wear and slow down the impact. Therefore, it includes, for example, the wear layer 89 and the buffer layer 90. 2 is a cross-sectional view of a region of the shoe designed to accommodate the arch of the foot, noting that the geometry of the base 12 is not planar, generally the same shape as the arch described above. According to the invention, the shoe 1 is actually fitted as described. Therefore, it is not necessary to add an inner sole in the shoe 1, although the increase can satisfy the need to fit the arch of the foot or other parts of the sole. The invention thus simplifies the manufacture of the shoe 1 as compared to prior art shoes. The weight of the shoe 1 is also reduced, thus reducing mechanical inertia. One advantage is improved athletic performance. For example, shoes made in accordance with the present invention are well suited for long distance runners.

Figure 2 also shows that almost the entire reinforcement 51 is located between the first layer of cladding 21 and the second layer of cladding 31.

Still referring to Fig. 2, while referring to Fig. 1, it is observed that the first layer of cladding 21 and the second layer of cladding 31 are continuous in cross section. Even with the pleats, the coverings can extend to their tips 29, 39, respectively, in a continuous manner, and thus extend to the top end 13 of the shoe to completely and permanently wrap the foot.

Referring to FIG. 1, while referring to FIG. 3 and FIG. 4, the first layer of the covering body 21 and The boundary between the second layer of cladding bodies 31 has a pleated layer 93 that defines a shoe opening 94. The periphery of the shoe opening 94 is defined by folding the two layers of the covering bodies 21, 31 to each other. This means that the perimeter may not require sewing or patching as in the prior art, and therefore, the shoe 1 does not impart a discomfort to the wearer including the shoe opening 94.

Other embodiments of the present invention will be briefly described below with reference to FIGS. 11 and 12. For the sake of convenience, only the differences from the first embodiment will be specifically described. In addition, the same element symbols are used for the same or similar components as in the first embodiment.

According to a second embodiment, as shown in Figure 11, the article of footwear or shoe 1 comprises an outer edge 6 and an inner edge 7, or a bottom 12 and a top end 13. Also included is a first layer of cladding 21, a second layer of cladding 31, a stiffener 51, a lace aperture 62 or a tongue 71.

The second embodiment is unique in that it further includes an insert member 101 between the two layers of cladding bodies 21, 31. The insert member 101 is part of a sole 102 that is on the bottoms 28, 38 of the first layer of cladding 21 and the second layer of cladding 31, and the embedded component 101 of the sole 102 extends from the rear end 104 in length To the front end 105, extending between the outer edge 106 and the inner edge 107 in width, and extending from the lower surface 108 to the upper surface 109 in height. The insert member 101 allows it to move relative to the portion of the wrap it is in. This case involves all or part of the bottoms 28, 38 of the cladding bodies 21, 31. Because this allows it to be reversibly elastically compressed, for example, at special stresses, the embedded parts can bring the relevant parts of the cladding closer together and then restore the natural spacing. This spacing corresponds to the thickness of the embedded component. This allows the foot to absorb impact or shock buffer. Another attendant benefit is that, for example, the wearer's joints can be protected.

For purposes of limitation, in accordance with a second embodiment of the present invention, the insert member, i.e., portion 101 of the sole 102, is relative to the first layer of cladding 21 and the second layer. The entire bottom 28, 38 of the cladding 31 extends. This allows a cushioning effect to be obtained at the entire bottom 12 of the article of footwear.

The insert member 101 can be identical to the previous description of the tongue 71, for example, with the first layer of cladding 21 and/or the second layer of cladding 31. The joining may be in any suitable manner, such as bonding, or other equivalent or additional techniques. This optimizes the engagement between the bottoms 28, 38 of the claddings 21, 31 to more accurately transmit shock or sensory information. Alternatively, it may be provided that the insert part is not joined to the bottom.

In order to achieve its function under the best conditions, the insert member 101 comprises an elastically deformable layer of synthetic material. This material layer can be made of ethylene vinyl acetate foam (EVA), polyurethane foam, polyethylene foam, or any other material that achieves the same function. The embedded component or portion 101 can include multiple portions, such as multiple layers disposed in a mutually overlapping manner in a suitable manner, and can also include natural materials such as cork or the like.

In addition, it can be observed that the article of footwear 1 comprises a wear layer 111 and at least one intermediate layer 112 disposed between the bottoms 28, 38 of the cladding bodies 21, 31 and the wear layer 111, and is resistant to wear. Layer 111 and intermediate layer 112 form the outer sole. This results in a certain buffering capacity directly at the wear layer.

A third embodiment of the invention will now be described. According to Fig. 12, an article of footwear or shoe 1 has an outer edge 6 and an inner edge 7, or a bottom 12 and a top end 13. Also included is a first layer of cladding 21, a second layer of cladding 31, a stiffener 51, a lace aperture 62 or a tongue 71. As shown in the second embodiment, the article of footwear of the third embodiment further has an insert member 121 between the two layers of covering bodies 21, 31. The insert member 121 is a portion of the sole 122 that is located on the bottoms 28, 38 of the first layer of cladding 21 and the second layer of cladding 31. The embedded component 121 of the sole 122 extends in length from the rear end 124. Extending to the front end 125, extending between the outer edge 126 and the inner edge 127 in width, extending from the lower surface 128 to the upper surface 129 in thickness. The insert member 121 allows it to move relative to the portion of the wrap it is in. This situation involves all or part of the bottoms 28, 38 of the cladding bodies 21, 31. Because this allows it to be reversibly elastically compressed, such as in special stresses, the embedded parts can bring the relevant parts of the cladding closer together and then restore the natural spacing. This spacing corresponds to the thickness of the embedded component. This allows the foot to achieve impact absorption or shock cushioning. Another benefit that comes with it is that it protects the wearer's joints, for example.

For purposes of limitation, in accordance with a third embodiment of the present invention, the insert member, i.e., portion 121 of the sole 122, is relative to the entire bottom portion 28, 38 of the first layer of cladding 21 and the second layer of cladding 31. extend. This allows a cushioning effect to be obtained at the entire bottom 12 of the article of footwear.

The insert member 121 is joined to, for example, the first layer covering body 21 and/or the second layer covering body 31. The joining may be in any suitable manner, such as bonding, or other equivalent or additional techniques. This optimizes the engagement between the bottoms 28, 38 of the claddings 21, 31 to more accurately transmit shock or sensory information. Alternatively, it may be provided that the insert part is not joined to the bottom.

In order to achieve its function under the best conditions, the insert member 121 comprises an elastically deformable layer of synthetic material. This material layer can be made of ethylene vinyl acetate foam (EVA), polyurethane foam, polyethylene foam, or any other material capable of achieving the same function. The embedded component or portion 121 can include multiple portions, such as multiple layers disposed in a mutually overlapping manner in a suitable manner, and can also include natural materials such as cork or the like.

A special feature of the third embodiment of the present invention is that the article of footwear 1 comprises A wear layer 131 is bonded directly to the bottom 38 of the cladding. As such, the bottom 38 of the second layer of cladding 31 defines the exterior of the article of footwear. This structure facilitates a more direct transmission of impulse and sensory information.

In other words, the sole cushioning portion 121 is fully engaged with the upper, which provides the shoe with an appearance that only the sole is visible. Therefore, with a simple structure and reasonable production cost, an aesthetic effect that requires double or more costs can be obtained. It is also possible to combine the two embodiments of Fig. 11 and Fig. 12, that is, the insert member 101 is located between the two layers of the covering bodies 21, 31, or between a layer of the covering body and the reinforcing member 51 as an inner sole, and, for example, As shown in Fig. 12, the insert member 121 is interposed between the two layers of covering bodies 21, 31 as an outer sole.

In both cases, in fact, the cladding of the sole cushioning embedded members 101, 121 makes it possible to selectively use a wider range of materials because the abrasion resistance stress can be provided by the covering bodies 21, 31. In addition, since the embedded components are invisible, they do not affect the aesthetic requirements, and the embedded components can be manufactured by cutting instead of molding, thereby reducing the manufacturing cost and, moreover, making a wider selection of materials. These embedded parts.

The present invention is not limited to the embodiments described above, and includes all equivalent techniques falling within the scope of the subsequent claims.

In particular, it is conceivable to incorporate one or more insert parts in other parts of the article of footwear, for example, a toe that protects the toes at the front end, an auxiliary support for the heel at the rear end, or a side protection ankle.

It is also conceivable to add one or more layers of covering to the article of footwear 1 .
