Description

Shoes for barefoot walking {SHOES FOR BAREFOOT WALKING EXERCISE}

The present invention relates to shoes for barefoot walking exercise.

Modern people wear shoes to protect their feet from dangerous objects on the ground and to absorb shock from the ground while walking. Recently, shoes with various soles or heels are being released for style. However, such shoes can limit the natural movement or condition of human muscles or joints.

Meanwhile, the feet function throughout human movement and are designed to withstand strong loads and twists and absorb shock. The human body has approximately 206 bones, and approximately 26 bones are located in one human foot alone. And the foot has a very complex structure consisting of 64 muscles and 56 ligaments.

Due to the above ergonomic features, many studies on feet have been conducted for a long time. Many peripheral nerves are gathered in the feet, and in particular, Oriental medicine believes that relieving fatigue in the feet and promoting blood circulation is very beneficial to health, considering that the acupuncture points of the human feet are connected to each organ of the body.

Due to the importance of the feet described above, companies that specialize in foot massage have appeared and interest in barefoot walking is increasing. Barefoot walking exercise is generally performed on safely maintained hiking trails or walking trails. Barefoot walking refers to walking without wearing shoes, that is, with the soles of the feet in contact with the ground. When you walk barefoot, the soles of your feet are naturally stimulated by the dirt or gravel on the ground, and you can feel the cold energy on your skin, allowing you to walk coolly and comfortably.

On the other hand, there are some uncomfortable problems with taking off your shoes completely and doing barefoot walking exercises. First of all, when walking, the tip of your toe may get caught on the edge of a tree root and injure your toe. Also, I have a complex about walking with my feet completely exposed. Even though you want to enjoy a walk with a peaceful mind without worrying about what others think, other people's strange looks at you not wearing shoes are a factor that prevents you from completely resting. Another problem is the possession of shoes. Generally, in order to exercise barefoot walking, you wear shoes to a well-maintained walking trail or hiking trail, then take off your shoes from the trail and go for a walk. At this time, it is quite inconvenient to continue to carry the removed shoes in your hand.

Accordingly, the problem to be solved by the present invention is a barefoot walking exercise shoe with a novel structure that can protect the toes during barefoot walking exercise, provides the appearance of wearing shoes, and does not require separate shoes. is to provide.

The problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

A barefoot walking exercise shoe according to an embodiment for solving the above problem is a shoe including a combined upper and a sole, including a zipper that can separate the sole in the direction of the shoe ball. , It is configured to tilt and fix the first and second parts of the separated window to the instep side.

The first part and the second part may include a 1-1 fixing means and a 1-2 fixing means for mutually fixing each of the first part and the second part in a state in which the foot is tilted toward the instep side.

The 1-1 fastening means includes a first snap button fixed on the insole of the first part, and the 1-2 fastening means includes a strap fixed on the insole of the second part, and disposed at an end of the strap. and may include a second snap button configured to be coupled to the first snap button.

In addition, the first part and the second part may each include fixing means for being fixed to the upper in a state where the foot is tilted toward the instep.

The outsole of the window may have a groove pattern forming irregularities of a predetermined height.

At this time, when the outsole is placed in contact with the ground, the zipper teeth of the zipper may be configured not to contact the ground due to the height of the groove pattern.

The total thickness of the window may be 1.5 cm or less.

Additionally, the window may include a silicone material.

Specific details of other embodiments are included in the detailed description.

According to embodiments of the present invention, for example, you can wear them like regular shoes from home to a walking trail, but if you want to do barefoot walking, open the zipper of the sole, flip the sole over, and fix it on the upper. can do.

This allows the sole of the foot to be exposed and in contact with the ground, while the top and front of the toes are still protected by the upper. In addition, the soles of the feet can be exposed without having to take off the shoes, which solves the complex about the gaze of others and the problem of having removed shoes.

1 is a perspective view of a shoe according to an embodiment of the present invention. Figure 2 is a bottom view showing the position of the outsole of the shoe in Figure 1.

Referring to FIGS. 1 and 2 , the shoe 10 according to this embodiment may include an upper 100 and a sole 200.

Upper 100 (or upper) refers to the entire upper part of the shoe 10. Specifically, the upper 100 includes a pronunciation 110 (or vamp) that covers the forefoot of the foot or the top of the toes, a tongue, a heel tab, and a back counter. ) and the like may further be included. The upper 100 may have a top line 100h (or a shoe entrance) where a person can put his or her foot.

The upper 100 may be made of a material that protects a person's feet and has a certain degree of flexibility so as not to cause discomfort in movement, for example, synthetic fiber or leather. Additionally, the proclamation 110 may have a certain level of breathability.

1 and the like illustrate a shoe 10 without shoelaces, but of course the present invention is not limited thereto.

In an exemplary embodiment, second fixing means 292a and 292b, specifically a 2-1 fixing means 292a, may be disposed on the upper 100. The 2-1 fixing means 292a may be disposed approximately near the top line 100h, near the person's ankles, or near the heel tab or back count. The second fixing means 292a and 292b will be described in detail later.

The window 200 (or sole) may be fixed to the upper 100 by adhesive or other methods. The window 200 may refer to the lower portion excluding the upper 100. Specifically, the sole 200 may include an insole 220 (or insole), a midsole 230 (midsole), and an outsole 210 (outsole) (or sole, or outsole). there is.

In some embodiments, the perimeter, or edge line, of the window 200 may not be fully coupled to the upper 100 but may have a partially unattached area. A gap may exist between the bottom of the upper 100 and the window 200 in the non-attached area. The gap can also be understood as an incision line.

For example, a first front gap 251a may be formed along the inner part of the foot near the toe of the foot, and a second front gap 251b may be formed along the outer part of the foot near the toe of the foot. The first front gap 251a and the second front gap 251b may not be connected but may be spaced apart or may be connected. If they continue, they can be combined and referred to as the anterior gap. The first front gap 251a and the second front gap 251b may extend to the widest part of the shoe, but the present invention is not limited thereto.

In some embodiments, a first rear gap 253a may be formed along the medial portion of the foot near the heel or heel tab of the foot, and a second rear gap 253b may be formed along the outer portion of the foot near the heel or heel tab of the foot. You can. The first rear gap 253a and the second rear gap 253b may not be connected but may be spaced apart or may be connected. If they continue, they can be combined and referred to as the posterior gap. The length, that is, the cut length, of the first rear gap 253a and/or the second rear gap 253b may be shorter than the first front gap 251a and the second front gap 251b, respectively.

As will be described later, in the shoe 10 according to this embodiment, the first and second portions of the sole 200 can be flipped and flipped to expose the sole. At this time, a predetermined gap or cut line may be provided between the sole 200 and the upper 100 of the shoe 10 to reduce the deformation force applied to the shoe when the sole 200 is turned over.

The insole 220 is a surface that directly faces the sole of a person's foot when the person wears the shoe 10, and may provide the function of absorbing shock or absorbing sweat.

The outsole 210 is the part where the shoe 10 touches the ground, has an uneven pattern to prevent slipping, and may be made of a material with high friction. In addition, since it is a part that is in continuous contact with the ground, it has a certain level of wear resistance and can be made of a material with excellent strength and rigidity.

The midsole 230 may be interposed between the insole 220 and the outsole 210. The midsole 230 may provide the function of absorbing and distributing the load due to the impact or human weight that occurs when the outsole 210 contacts the ground. The midsole 230 may be made of a material with excellent elasticity.

As described above, the window 200 may be formed by stacking the insole 220, the midsole 230, and the outsole 210. In some embodiments, at least the midsole 230 and the outsole 210 may be provided integrally. Hereinafter, the insole 220 may refer to the uppermost layer of the window 200, or the inner surface of the window 200, that is, the upper surface of the insole 220, or the insole surface. In addition, the outsole 210 may refer to the lowest layer of the window 200, or the outer surface of the window 200, that is, the lower surface of the outsole 210.

In an example embodiment, window 200 may include a zipper or zipper structure 270. The zipper 270 may include a zipper row 271 (or zipper row) and a slider 272 inserted into the zipper row 271. In addition, although not shown in the drawing, a first stopper (not shown) (or first stopper) and a second stopper (not shown) (or second stopper) that limit the movement range of the slider 272 of the zipper 270 It may further include iron). In a state in which the zipper teeth 271 on both sides of the zipper are engaged by the slider 272, that is, in the closed state of the zipper 270, the handle or pull-tab and crown of the slider 272 are used to hold the shoe ( 10), that is, it may be located on the outsole 210 side. That is, a person may be configured to operate the slider 272 exposed on the bottom of the shoe 10 while wearing the shoe 10.

The zipper 270 according to this embodiment extends in the longitudinal direction of the shoe 10, and the window 200 may be configured to open in the direction of the ball of the shoe. Specifically, the window 200 includes first parts 210a and 220a and second parts 210b and 220b arranged in the width direction, and the ends of the first parts 210a and 220a and the second part ( It may include a zipper 270 forming a coupling structure at the ends of 210b and 220b). In other words, the zipper 270 may be configured to separate the first portions 210a and 220a and the second portions 210b and 220b of the window 200 in the foot width direction. Figure 2 illustrates a case where the extension direction of the zipper 270, specifically the extension direction of the zipper rows 271, is implemented as a straight line. However, in other embodiments, the zipper rows 271 may not be completely straight. The zipper row 271 is meant to include a first zipper row 271a coupled to the first part 210a, 220a and a second zipper row 271b coupled to the second part 210b, 220b. .

As described above, the lower surface of the window 200, that is, the surface of the outsole 210, is the part that contacts the ground when a person walks wearing shoes 10 and must provide a certain amount of friction. Therefore, protruding parts or materials such as metal or plastic may be undesirable.

For this purpose, when a person wears the shoe 10 and the outsole 210 is in contact with the ground, the pull tab and crown of the slider 272 of the zipper 270 are exposed to the surface of the outsole 210, but are spaced apart from the ground. This may be desirable. In an exemplary embodiment, the outsole 210 may include a groove pattern that forms irregularities of a predetermined height to increase friction. At this time, the depth of the groove pattern may be greater than the thickness formed by the pull tab and crown of the zipper 270. In other words, the zipper row 271, slider 272, etc. of the zipper 270 are not formed on the part of the groove pattern of the outsole 210 that protrudes toward the ground, but on the part that is recessed toward the insole 220. It can be. If the above structure is followed, the zipper 270 can be configured so that it does not contact the ground.

Hereinafter, a modified structure for barefoot walking using the shoe 10 according to this embodiment will be described. Figure 3 is a perspective view showing the shoe of Figure 1 in a partially deformed state. Figure 4 is a perspective view showing the shoe of Figure 1 in a completely deformed state, for example, the second state 10b.

Referring further to FIGS. 3 and 4, the shoe 10 according to the present embodiment connects the sole 200 to first portions 210a and 220a and second portions 210b using the zipper 270 of the sole 200. , 220b), and the separated first parts 210a and 220a and the second parts 210b and 220b can be respectively bent in the width direction of the foot and fixed on the instep side of the person's foot, that is, on the upper 100. In order to flip and fix the window, the total thickness of the window 200 according to this embodiment, that is, including the insole 220, midsole 230, and outsole 210, may be about 1.5 cm or less. In addition, while the window 200 has sufficient abrasion strength, etc., it can have high flexibility so that it can be flipped over and fixed on the instep. For example, at least the midsole 230 and the outsole 210 may be made of a silicone material. In some embodiments, the midsole is omitted, and the outsole 210 and the insole 220 may be coupled in direct contact with each other.

As the sole 200 is divided into first parts 210a and 220a and second parts 210b and 220b and is bent toward the upper 100, the sole 200 may not exist in the lower part of the shoe 10. there is. This may expose the soles of a person's feet.

As explained earlier, barefoot walking exercise can provide beneficial effects on a person's health, but there are some inconvenient problems with barefoot walking exercise. First, the problem is that the top and front of the toes are not protected when the shoes are completely taken off. There may occasionally be tree roots or stones protruding from hiking trails. In this case, if the front part of a person's toes gets caught on a tree root or stone while walking, it can cause injury. However, according to this embodiment, even though the sole of the foot is exposed by flipping the sole 200, the front and upper parts of the toes can still be protected using the upper 100.

The second problem is the problem of other people's perspectives. Although it is widely known that barefoot walking is useful, other people's curious looks at a person walking without shoes can be a factor that prevents complete rest. However, according to this embodiment, only the sole of the foot is exposed, and the visible upper part of the shoe 10 is still surrounded by the upper 100 and the sole 200, so it may not attract the attention of others.

The last problem is the issue of possession of shoes. In the past, it was common to wear shoes when going to a well-maintained hiking trail, take off your shoes only to do barefoot walking on the trail, and walk with your shoes in your hand or in your bag. Therefore, there are inconveniences such as having to carry the shoes in hand or carrying a bag to store the shoes. However, according to this embodiment, if you want to walk barefoot, you have the advantage of being able to open the window 200 using the zipper 270 and do barefoot walking anytime, anywhere.

Meanwhile, the first parts 210a and 220a and the second parts 210b and 220b of the window 200, which are bent and fixed on the upper surface of the upper 100, may be fixed on the upper 100. For this purpose, one or more fixing means may be provided.

In an exemplary embodiment, first fixing means 291a and 291b may be provided on the inner surface of the window 200, that is, the insole surface on the insole 220 side. Specifically, the 1-1 fixing means (291a) is disposed on the insole surface of the first portion (210a, 220a), and the 1-2 fixing means (291b) is disposed on the insole surface of the second portion (210b, 220b). can be placed. And the 1-1st fixing means 291a and the 1-2nd fixing means 291b may be reversibly coupled to each other on the upper 100. The type of the 1-1 fixing means 291a and the 1-2 fixing means 291b is not particularly limited as long as they can be firmly coupled to each other, but a small area is used so as not to cause discomfort when a person wears the shoes 10. In terms of being configured to occupy, the 1-1st fixing means 291a and the 1-2nd fixing means 291b may include snap buttons.

As a non-limiting example, the 1-1 fixing means 291a may include a female snap button or a male snap button (or a first snap button). In addition, the 1-2 fixing means 291b includes a corresponding male-snap button or female-snap button (or a second snap button) to form a connection with the 1-1 fixing means 291a, and the strap More may be included. When the first parts (210a, 220a) and the second parts (210b, 220b) are turned over and tilted to the instep side, when the first parts (210a, 220a) and the second parts (210b, 220b) are made of a material with high flexibility. However, the first portions 210a and 220a and the second portions 210b and 220b may be spaced apart from each other on the upper 100 due to the curvature of the shoe 10, the height and shape of the instep, etc. Therefore, at least one of the 1-1 fixing means 291a and the 1-2 fixing means 291b is high so as to overcome the separation distance between the first parts 210a and 220a and the second parts 210b and 220b. It may include an elastic strap. Also, by placing a snap button at the end of the strap, the 1-1 fixing means 291a and the 1-2 fixing means 291b can be fixedly coupled. Specifically, the strap of the 1-2 fixing means 291b may be fixed on the insole surface of the insole 220, and the snap button of the 1-2 fixing means 291b may be disposed at the end of the strap.

In another embodiment, instead of being a snap button, the 1-1st fixing means 291a and the 1-2nd fixing means 291b may be configured to be fitted with protrusions and grooves that engage with each other. In addition, Figures 3 and 4 show that the 1-1st fixing means (291a) and the 1-2nd fixing means (291b) are arranged adjacent to the first zipper row (271a) and the second zipper row (271b), respectively. Illustrate the case. In this case, in the first state 10a where the window 200 covers the sole of the person's foot, the 1-1 fixing means 291a and the 1-2 fixing means 291b are located approximately near the center in the width direction of the person's foot. can be located In another embodiment, the 1-1 fixing means and the 1-2 fixing means are located at the width direction edge on the insole 220 in the first state 10a, and the 1-2 fixing means in the second state 10b. The strap of (291b) may be shaped to completely cross the shoe.

The first parts (210a, 220a) and the second parts (210b, 220b) of the window 200, which is tilted toward the instep, can be fixed to the instep using the first fixing means (291a, 291b) described above. It is obvious that the surface of the window 200 exposed at this time may be the inner surface of the window 200, that is, the insole surfaces 220a and 220b.

Meanwhile, in some embodiments, the shoe 10 may further include second fixing means 292a and 292b. The second fixing means 292a and 292b may include a 2-1 fixing means 292a and a 2-2 fixing means 292b that can be reversibly coupled to each other.

The 2-1 fixing means 292a may be attached to the upper 100. Specifically, it may be placed near the top line 100h of the upper 100, near the person's ankles, or near the heel tab or back count. Additionally, the 2-2 fixing means 292b may be disposed on the insole surfaces of the first parts 210a and 220a and the second parts 210b and 220b of the window 200, respectively. That is, the 2-2 fixing means 292b may include the 2-2 fixing means (not shown) of the first part and the 2-2 fixing means 292b of the second part.

The types of the 2-1 fixing means (292a) and the 2-2 fixing means (292b) are not particularly limited, but the 2-1 fixing means (292a) and the 2-2 fixing means (292b) are snap buttons. may include.

As a non-limiting example, the 2-1 fixing means 292a may include a male snap button or a female snap button. In addition, the 2-2 fixing means 292b may include a corresponding female-snap button or male-snap button to form a connection with the 2-1 fixing means 292a, and may further include a strap. That is, the 2-2 fixing means 292b may include a strap with high elasticity as well as a snap button. A strap of the 2-2 fixing means 292b may be fixed on the insole surface of the insole 220, and a snap button of the 2-2 fixing means 292b may be disposed at an end of the strap.

The first fixing means (291a, 291b) and the second fixing means (292a, 292b) of the shoe 10 according to this embodiment use snap buttons so that the size for fixed combination can be small, but the first fixing means ( Any one of the coupling elements of 291a, 291b) (for example, the 1-2 fixing means 291b) and any one of the coupling elements of the second fixing means 292a, 292b (for example, the 2-2 fixing means 292b) may include a strap with high elasticity.

If, unlike the present embodiment, there is no strap, for example, a snap button disposed on the upper is selected as the 2-1 fixing means and a snap button disposed on the insole surface is selected as the 2-2 fixing means, so that they are immediately attached. When combined, the impact applied to the shoe can be directly applied to the second fixing means. In other words, in the process of walking in shoes in the second state, twisting forces in various directions act on the shoes, and if the connection is formed immediately without a strap that cannot relieve the impact, the connection structure can be easily released. However, by arranging a strap with a certain amount of elasticity between elements forming a bond as in the present embodiment, even when a force such as twisting is applied to the shoe 10, the elastic strap absorbs and disperses the force, It can alleviate the release of bonded structures.

In addition, the shoe 10 according to the present embodiment includes most coupling structures, for example, the 1-1 fixing means 291a, the 1-2 fixing means 291b, the 2-1 fixing means 292a, and Among the 2-2 fixing means 292b, the remaining fixing means except for the 2-1 fixing means 292a may be disposed on the inner surface of the window 200, that is, on the insole surface of the insole 220. Therefore, in the first state 10a, the exterior design of the shoe 10 can be provided neatly and not messy, and the 2-1 fixing means 292a is a snap button and can function as a design element in itself. .

Although the above description focuses on the embodiments of the present invention, this is only an example and does not limit the present invention, and those skilled in the art will understand the present invention without departing from the essential characteristics of the embodiments of the present invention. It will be apparent that various modifications and applications not exemplified above are possible.

Therefore, the scope of the present invention should be understood to include changes, equivalents, or substitutes of the technical ideas exemplified above. For example, each component specifically shown in the embodiments of the present invention can be modified and implemented. And these variations and differences in application should be construed as being included in the scope of the present invention as defined in the appended claims.
