Description

Grounding shoes for barefoot walking

[0001] The present invention relates to shoes, and more particularly, to grounding shoes for barefoot walking.

[0002] Barefoot walking is gaining significant attention these days as a healthy and natural form of exercise. Walking barefoot can contribute to improving overall metabolic rate by activating the microscopic muscles in the soles of the feet. Consistent barefoot walking can promote fat burning. Specifically, increased muscle activity can activate the process of converting body fat into energy.

[0003] Walking barefoot can activate a variety of muscles around the feet and ankles. This activates more muscle groups than walking with shoes on. Walking barefoot can induce full muscle activity, including not only the feet but also the legs, hips, lower back, and back muscles. This provides a more integrated workout and can help maintain muscle balance.

[0004] Among the many benefits of walking barefoot, the grounding effect is arguably the most notable. This effect involves free electrons, negatively charged (-), from the ground entering the body and neutralizing positively charged oxygen radicals. These oxygen radicals are byproducts of the process of energy production within cells, called mitochondria, which utilize oxygen to generate energy. If these oxygen radicals are not immediately expelled from the body, they can lead to various diseases.

[0005] As the benefits of barefoot walking become widely known, many people of all ages and genders are practicing barefoot walking. However, because barefoot walking is done outdoors, without shoes, it is inevitably affected by the weather. This is especially true in the cold winter months, making barefoot walking unsuitable. Furthermore, because barefoot walking requires direct contact with the ground, some individuals may avoid it due to psychological concerns about foot contact or injury.

[0006] The present invention is intended to solve the above-described problem, and an object of the present invention is to provide grounding shoes for barefoot walking that can obtain the grounding effect of barefoot walking even in cold weather or when one feels uncomfortable with one's bare feet touching the ground.

[0007] According to an embodiment of the present invention, a grounding shoe for barefoot walking may include a sole portion anchored to the ground; and an upper skin covering an upper surface of the sole portion and forming a space between the sole portion and the upper skin for receiving a foot. The sole portion may include a sole bottom portion made of a conductive material for grounding the foot to the ground and having a plurality of line grooves; a sole front portion connected to the sole bottom portion and having a front line; a sole back portion connected to the sole bottom portion and having a back line; a sole inner side portion connected to the sole bottom portion and having a front side line; and a sole outer side portion connected to the sole bottom portion and having an outer side line. The grounding shoe for barefoot walking may have a thickness of the sole bottom portion such that a voltage value becomes 0 when a voltage is measured between the foot and the ground.

[0008] As an embodiment, the shoe may further include a bottom portion formed on the sole portion between the sole portion and the upper portion and made of conductive fiber.

[0009] As an embodiment, the sole bottom portion may include a plurality of main vein lines having a plurality of line grooves extending toward the front side of the sole or the back side of the sole; a plurality of side vein lines having a plurality of line grooves extending toward the inner side of the sole or the outer side of the sole; and a border line formed at a boundary portion between the sole bottom portion and the inner side of the sole, and at a boundary portion between the sole bottom portion and the outer side of the sole.

[0010] As an example, the thickness of the bottom of the sole so that the voltage value becomes 0 when measuring the voltage between the foot and the ground may be 3 mm or less.

[0011] The grounding shoes for barefoot walking exercise according to an embodiment of the present invention enable continuous exercise even in cold winter or when one is reluctant to walk barefoot, and can obtain the grounding effect of barefoot walking exercise.

[0018] A drawing showing the best mode for carrying out the present invention is FIG. 3.

[0019] Hereinafter, embodiments of the present invention will be described clearly and in detail to the extent that a person having ordinary skill in the art can easily practice the present invention.

[0020] FIG. 1 is a photograph exemplarily showing a grounding shoe for barefoot walking exercise according to an embodiment of the present invention. Referring to FIG. 1, the grounding shoe for barefoot walking exercise (1000) may include a sole (1100), an upper (1200), and a bottom (1300).

[0021] The grounding shoe (1000) for barefoot walking exercise according to one embodiment of the present invention may be provided as various types of shoes. For example, the grounding shoe (1000) for barefoot walking exercise may be provided as a sneaker or sports sandal that can be comfortably worn during barefoot walking exercise.

[0022] The sole (1100) is the bottom surface of the grounding shoe (1000) for barefoot walking exercise that touches the ground. The upper part (1200) covers the upper surface of the sole part (1100). The upper part (1200) forms a space between the sole part (1100) and the upper part for accommodating the foot. The upper part (1200) may be provided with various materials that can be used as the upper of the shoe (1000) for grounding shoe for barefoot walking exercise, such as leather, natural fiber, or synthetic fiber.

[0023] The sole (1100) may be composed of a flexible conductive material to enhance the grounding effect. For example, the sole (1100) may be composed of conductive rubber. The conductive rubber of the sole (1100) may include a large number of carbon fibers. When the grounding shoe (1000) for barefoot walking is worn, the carbon fibers are pressed, and when pressed, they are grounded and electricity is conducted, thereby achieving a grounding effect.

[0024] The bottom portion (1300) may be formed on the bottom portion (1100) between the sole portion (1100) and the upper portion (1200). The bottom portion (1300) is the part that touches the sole of the foot. The bottom portion (1300) may be composed of thin conductive fibers. The conductive fibers may be fibers in which carbon particles capable of inducing electric charges are mixed into the raw material of synthetic fibers.

[0025] The grounding shoe (1000) for barefoot walking according to an embodiment of the present invention can provide a grounding effect similar to barefoot walking in cases where walking barefoot is uncomfortable due to cold weather or walking on bare ground is averse. Since the grounding shoe (1000) for barefoot walking is manufactured using a conductive material, it can provide a grounding effect when walking on bare ground.

[0026] FIG. 2 is a photograph showing the sole portion illustrated in FIG. 1. Referring to FIG. 2, the sole portion (1100) includes a sole bottom portion (1110), a sole front portion (1120), a sole back portion (1130), a sole inner side portion (1140), and a sole outer side portion (1150). The sole portion (1100) is made of a conductive material and can have a grounding effect during barefoot walking. For example, the conductive material constituting the sole portion (1100) may be conductive rubber or conductive silicone.

[0027] The sole (1110) is shaped like a leaf vein to enhance grounding effectiveness. Leaf veins are a network of tissues found on plant leaves. They include a main vein and a lateral vein. These veins are connected to the stem's vascular bundles and serve as conduits for nutrients and water.

[0028] The sole bottom portion (1110) can act as a passage for air on dry ground and a passage for water when there is water, like the veins of a leaf when it touches the ground. The sole bottom portion (1110) can include a plurality of main vein lines and a plurality of side vein lines. The main vein lines have a shape that extends toward the front portion (1120) of the sole or the side portion (1130) of the sole. The side vein lines have a shape that extends toward the inner side portion (1140) of the sole or the outer side portion (1150) of the sole.

[0029] The sole bottom (1110) includes main vein lines and lateral vein lines, thereby facilitating the movement of air and water and enhancing the grounding effect. In addition, the sole bottom (1110) maximizes the elasticity of the sole and provides walking comfort when wearing the shoes for barefoot walking due to the grooves of the main vein lines and lateral vein lines. The shoes for barefoot walking (1000) can maximize the walking effect due to the leaf-like structure of the sole bottom (1110).

[0030] Fig. 3 is a drawing showing an example of the sole portion illustrated in Fig. 2. Referring to Fig. 3, the sole portion (1100) includes a sole bottom portion (1110), a sole front portion (1120), a sole back portion (1130), a sole inner side portion (1140), and a sole outer side portion (1150).

[0031] The sole (1100) may be composed of a material such as conductive rubber or conductive silicone. The thickness of the sole (1100) may be such that current flows between the foot and the ground and the voltage value becomes 0 when measured. For example, the thickness of the sole bottom may be 3 mm.

[0032] The sole (1100) is shaped like the veins of a leaf to enhance ground contact during walking. The sole bottom (1110) is inspired by the main veins, lateral veins, and surface cells of a leaf. The main veins and lateral veins of a leaf serve as passages for the movement of nutrients and moisture, while the surface cells of the leaf take in air and perform photosynthesis.

[0033] The sole bottom portion (1110) can be divided into three parts, L1, L2, and L3. The width gradually increases from the front portion (1120) of the sole to L1, and can have a maximum length of A1. The present invention makes the length of A1 longer than that of a typical shoe, thereby widening the front portion, allowing the toes to move freely as if walking barefoot.

[0034] From L1 to L2, the width gradually narrows and can have a minimum length of A2. From L2 to L3, the width gradually widens and can have a maximum length of A3. From L3 to the back of the sole (1130), the width gradually narrows again. The lengths of A1 to A3 have a constant ratio but can vary depending on the shoe size.

[0035] The sole bottom portion (1110) may include a main vein line (1111), a lateral vein line (1112), a border line (1113), and a protrusion (1114). The sole bottom portion (1110) has a plurality of main vein lines and a plurality of lateral vein lines. The main vein line (1111) has a plurality of line grooves extending toward the front side portion (1120) of the sole or the back side portion (1130) of the sole. The lateral vein line (1112) has a plurality of line grooves extending toward the inner side portion (1140) of the sole or the outer side portion (1150) of the sole.

[0036] The sole bottom (1110) can facilitate the movement of air and water through line grooves formed on the main vein line (1111) and the lateral vein line (1112), and can minimize the gap between the sole and the ground to enhance the grounding effect. In addition, the sole bottom (1110) can maximize the elasticity of the sole when walking in shoes, and provide comfort to the movement of the feet when walking.

[0037] The border line (1113) may be formed at the boundary between the sole bottom portion (1110) and the inner side portion (1140) of the sole and at the boundary between the sole bottom portion (1110) and the outer side portion (1150) of the sole. The border line (1113) may be formed to meet the lateral vein line (1112) at the boundary between the inner side portion (1140) of the sole or the outer side portion (1150) of the sole.

[0038] The protrusion (1114) is shaped like a cell on the surface of a leaf and protrudes from the surface of the sole bottom (1110). While the main vein line (1111), lateral vein line (1112), and edge line (1113) have grooves that extend inward from the surface, the protrusion (1114) protrudes outward from the surface. The protrusion (1114) can prevent slipping and enhance the exercise effect by increasing friction with the ground.

[0039] The front part of the sole (1120) is connected to the bottom part of the sole (1110) and may have a front line (1121) that is semicircular when viewed from the front of the shoe. The front line (1121) may be connected to two main vein lines of the bottom part of the sole (1110). The front part of the sole (1120) may have a height B from the bottom part of the sole (1110). For example, the length B may be 26 to 32 mm.

[0040] The rear side of the sole (1130) is connected to the bottom side of the sole (1110) and may have a semicircular rear line (1131) when viewed from the back of the shoe. The rear side of the sole (1130) may have one rear side line (1132) on each side of the rear side line (1131). The rear side line (1131) and the rear side line (1132) may be connected to the main lines of the bottom side of the sole (1110). The rear side of the sole (1130) may have a height C from the bottom side of the sole (1110). For example, the length C may be 26 to 32 mm.

[0041] The inner side portion (1140) of the sole is connected to the sole bottom portion (1110) and may have an inner side line (1141) in a bow shape when viewed from the inside of the shoe. The inner side portion (1140) of the sole may have a plurality of inner side lines (1142) next to the inner side line (1141). The inner side lines (1141) and the inner side lines (1142) may be connected to the main vein line (1111) and / or the lateral vein line (1112) of the sole bottom portion (1110). The inner side portion (1140) of the sole may have a height D1 from the sole bottom portion (1110). For example, the length D1 may be 26 to 32 mm.

[0042] The inner side portion (1140) of the sole can be divided into three parts by L1, L2, and L3. The portion from the front portion (1120) of the sole to L1 can have a first wave shape and can have a maximum height of D2. For example, the length of D2 can be 20 to 23 mm. The portions from L1 to L2 can have a second wave shape and can have a maximum height of D3. For example, the length of D3 can be 15 to 18 mm. The portions from L2 to L3 can have a third wave shape and can have a minimum height of D4 and a maximum height of D5. For example, the length of D4 can be 8 to 10 mm, and the length of D5 can be 19 to 22 mm. The portion from L3 to the rear portion (1130) of the sole can have a fourth wave shape and can have a maximum height of D6 from the bottom portion (1110) of the sole. For example, the length of D6 can be 29 to 31 mm.

[0043] The outer side portion (1145) of the sole is connected to the sole bottom portion (1110) and may have an outer side line (1151) in a bow shape when viewed from the outside of the shoe. The outer side portion (1150) of the sole may have a plurality of outer side lines (1152) next to the outer side line (1151). The outer side lines (1151) and the outer side lines (1152) may be connected to the main vein line (1111) and / or the lateral vein line (1112) of the sole bottom portion (1110). The outer side portion (1150) of the sole may have a height E1 from the sole bottom portion (1110). For example, the length E1 may be 26 to 32 mm.

[0044] The outer side surface (1150) of the sole can be divided into three parts by L1, L2, and L3. The sole front surface (1120) to L1 can have a first wave shape and can have a minimum height E2. For example, the E2 length can be 13 to 16 mm. The soles from L1 to L2 can have a second wave shape and can have a maximum height E3. For example, the E3 length can be 18 to 22 mm. The soles from L2 to L3 can have a third wave shape and can have a minimum height E4 and a maximum height E5. For example, the E4 length can be 8 to 10 mm, and the E5 length can be 19 to 22 mm. The sole back surface (1130) from L3 can have a fourth wave shape and can have a maximum height E6 from the sole bottom surface (1110). For example, the E6 length can be 29 to 31 mm.

[0045] Fig. 4 is a cross-sectional side view illustrating the grounding principle of the barefoot walking grounding shoe of Fig. 1. Referring to Fig. 4, the sole (1100) of the barefoot walking grounding shoe (1000) may be formed of conductive rubber. Additionally, the bottom (1300) may be formed of conductive fiber.

[0046] Conductive rubber has a certain resistance (R) and can conduct current. When a metal plate (2100) is placed under a grounding shoe (1000) for barefoot walking and the resistance is measured while in contact with the foot (10) under the upper part (1200), a certain resistance value can be displayed on the resistance meter (2000). In the case of general rubber, the resistance is infinite and therefore current does not flow, but conductive rubber has a certain resistance and can conduct current (I).

[0047] The conductive rubber of the sole (1100) may include a large number of conductive carbons. When the grounding shoes (1000) for barefoot walking are worn, the conductive carbons are pressed, and when the conductive carbons are pressed, they are grounded and current flows through them, thereby achieving a grounding effect.

[0048] Figures 5 and 6 are photographs showing the grounding effect of grounding shoes for barefoot walking exercise according to an embodiment of the present invention. Figures 5 and 6 show the results of an electrical resistance test of grounding shoes for barefoot walking exercise.

[0049] Referring to Figure 5, (A) shows the results of testing the electrical resistance of the ground, (B) shows the results of testing the electrical resistance in a barefoot state without wearing shoes, (C) shows the results of testing the electrical resistance in a state where grounding shoes for barefoot walking exercise are worn, and (D) shows the results of testing the electrical resistance in a state where regular shoes are worn.

[0050] In cases (A) to (C) of Fig. 5, the electrical resistance is displayed, whereas in case (D) where normal shoes are worn, OL, an abbreviation for Over the Limit, is displayed. As in case (D), if the electrical resistance is infinite and current does not flow, OL is displayed.

[0051] Referring to Fig. 6, in the case of (C) wearing grounding shoes for barefoot walking, it can be confirmed that the electrical resistance is displayed just as in the case of bare feet. Therefore, the grounding shoes (1000) for barefoot walking according to an embodiment of the present invention can achieve a grounding effect, unlike general shoes.

[0052] Figure 7 is a photograph showing the results of a voltage test on grounding shoes for barefoot walking. Referring to Figure 7, (A) shows the results of voltage measurement with bare feet and no shoes on, (B) shows the results of voltage measurement with grounding shoes for barefoot walking on, and (C) shows the results of voltage measurement with regular shoes on.

[0053] In the case of (B) wearing grounding shoes for barefoot walking, it can be confirmed that the voltage is displayed as 0, just like in the case of barefoot (A). In the case of (C) wearing regular shoes, it can be confirmed that the voltage value is displayed as a number. If the voltage is 0, it means that the voltage difference between the two ends is 0, so electricity flows well, and if a specific number is displayed, it means that there is a voltage difference, so electricity does not flow. Therefore, the grounding shoes (1000) for barefoot walking according to an embodiment of the present invention can obtain a grounding effect, unlike regular shoes.

[0054] The grounding shoe (1000) for barefoot walking according to an embodiment of the present invention is manufactured using conductive rubber and / or conductive synthetic fibers, thereby achieving a grounding effect when walking on bare ground. The present invention can achieve a grounding effect similar to barefoot walking in cases where walking barefoot is uncomfortable or one is reluctant to walk on bare ground due to cold weather.

[0055] The above description provides specific examples for implementing the present invention. In addition to the above-described embodiments, the present invention may also include embodiments that are simply designed or easily modified. Furthermore, the present invention may also encompass techniques that can be easily modified and implemented using the embodiments. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be defined not only by the claims set forth below but also by equivalents of the claims of the present invention.
