Description

[Technical field]

[0001] The present invention relates to foot socks for preventing cramps. [Background technology]

[0002] A cramp is a general term for muscle spasms that occur mainly in the calf muscles, and most often occur during sleep (often in the early morning). Many are accompanied by severe pain.

[0003] It is known that cramps are particularly likely to occur in people with diabetes or liver disease, the elderly, pregnant women, and people who are fatigued from sports. When cramps occur, they cause severe pain in the calves, so people who are prone to cramps worry that they might get a cramp while they are sleeping, which makes it difficult for them to get a good night's sleep.

[0004] For this reason, in order to prevent cramps from occurring while sleeping, some people place a pillow under the soles of their feet and sleep with their legs at an angle of about 90 degrees. Furthermore, the following Patent Document 1 discloses a method for preventing cramps.

[0005] Patent Document 1 describes a cramp prevention supporter that includes a toe insertion section into which the toes and toes including the metatarsals are inserted, belt-shaped band sections provided on both sides of the toe insertion section, and fixing members provided at the tips of each band section for removably fixing the tips of the band sections together, wherein the tips of each band section are pulled toward the ankle so as to draw the toes and toes including the metatarsals and instep inserted into the toe insertion section moderately toward the shin, and the band sections are wrapped around both sides of the ankle so as to cross over the instep, and the tips of the band sections are fixed around the ankle by the fixing members.

[0006] [Patent Document 1] JP 2012-183259 A Summary of the Invention [Problem to be solved by the invention]

[0007] The cramp prevention supporter in Patent Document 1 is a band-like device that has one end wrapped around the ankle, passed over the instep and wrapped around the forefoot (big to little toe) from below, and the other end crossed over the instep and wrapped around the ankle, fixedly connecting to the other end in a figure-eight shape.

[0008] That is, the connection must be fixed manually in an eight-shape, making installation tedious. In order to prevent cramps, it is preferable that the angle between the sole of the foot and the calf be approximately 95 degrees to 115 degrees.

[0009] To provide a pair of socks for preventing cramps, which can be worn as if wearing socks and can provide an appropriate angle for preventing cramps in the soles of the feet by putting the socks on as if wearing socks. [Means for solving the problem]

Furthermore, the leg sock for preventing cramps of the present invention is a sock-type leg sock for preventing cramps, in which the opening of the leg is between the knee and the calf when the leg is put in to the tip, a foot bag whose bottom surface is curved back at a predetermined angle toward the opening portion, and whose opening portion is located between the calf below the knee and the ankle, and has holes provided symmetrically at positions a predetermined distance from the lower surface of the tension portion; an inner bottom plate member connected from the front end to the rear end of the inner bottom surface of the foot bag; a plate-shaped tension part whose lower surface is connected from the predetermined location of the opening to the tip of the foot sole except for the vicinity of the connection hole and the vicinity of the ankle; a side zipper of a predetermined length connected to the instep side of the opening of the foot bag excluding the calf side; a plastic rubber band having a hook-and-loop fastener connected to its back surface, the plastic rubber band being sized to fit the side fastener of the foot bag and being connected to the side fastener of the foot bag; An outer bottom plate member provided on an outer bottom surface of the foot sole from a front end to a rear end thereof; a first length adjustment plate bar having one end connected to one end of the plastic rubber band and the other end connected to a first folded portion folded from one side with a predetermined gap at a location near the arch of the back surface of the outer bottom plate member, and having a first slide hole of a predetermined length formed from a position beyond the thickness of the outer bottom plate member and the gap; a second length adjustment plate bar, one end of which is connected to one end of the plastic rubber band, and the other end of which is connected to a second folded portion folded from the other side surface side facing the first length adjustment plate bar, and a second slide hole of a predetermined length is formed from a position exceeding the thickness of the outer bottom plate member and the gap; A rod provided below the outer member and passed through a first slide hole of the first length adjustment plate bar and a second slide hole of the second length adjustment plate bar; a first female screw that fixes one of the rods through the first slide hole, and a second female screw that fixes the other of the rods through the second slide hole; The present invention is characterized by having the following. Effect of the Invention

[0011] As described above, according to the cramp-preventing foot socks of the present invention, when, for example, one is sleeping, opening the connecting member connected to the foot bag and removing the wrapping band at the opening part of the foot bag, the inside of the bag expands, making it easy to insert the socks. When the foot is inserted into the foot bag up to the toes, the bottom plate member of the foot bag bends at a predetermined angle (the angle between the line passing through the calf end and the heel end and the sole of the shoe is 95 degrees to 125 degrees), so the sole of the foot bends at this predetermined angle. Furthermore, when the wrapping band at the opening of the foot bag is tightened, the tension part is pulled, and when the connecting member connected to the foot bag is closed, the tension part is further pulled because the tension part is joined over a predetermined range, so that the angle of the sole of the foot can be maintained at a predetermined angle (the angle of curvature between the horizontal line and the sole is 15 degrees to 25 degrees). Furthermore, with the foot socks for preventing cramps of the present invention, for example, when sleeping, the connecting member connected to the foot bag can be opened and the wrapping band around the opening part of the foot bag can be removed, allowing the inside of the bag to expand, making insertion easy. When the foot is inserted into the foot bag up to the toes, the bottom plate member of the foot bag bends at a predetermined angle (the angle between the line passing through the calf end and the heel end and the sole of the shoe is 95 degrees to 125 degrees), so the sole of the foot bends at this predetermined angle. Furthermore, when the wrapping band at the opening of the foot bag is tightened, the tension part is pulled, and when the connecting member connected to the foot bag is closed, the tension part is further pulled because the tension part is joined over a predetermined range, so that the angle of the sole of the foot can be maintained at a predetermined angle (the angle of curvature between the horizontal line and the sole is 15 degrees to 25 degrees). Furthermore, for example, when sleeping, the connection between the side zipper of the foot bag at the opening part of the foot bag and the plastic rubber band can be detached, and the male button of the first support bar and the female button of the second support bar can be removed from the foot bag, which will expand the inside of the bag and make insertion easier. Then, when the foot is placed up to the toes in the foot pouch and the male button on the first support bar is engaged with the female button on the second support bar through the connection hole of the foot pouch, and the side zipper of the foot pouch is connected to the plastic rubber band, the tension part is pulled and the entrance part does not slip off the calf. Therefore, even during sleep, the angle of the sole of the foot can be maintained at a predetermined angle (the angle of curvature between the horizontal line and the sole of the shoe is 15 degrees to 25 degrees). Furthermore, the cramp-preventing foot socks of the present invention allow height adjustment by an outer bottom plate member provided from the front to the rear end of the bottom surface of the outer side of the foot bag, a first length-adjusting plate bar with a first slide hole, a second length-adjusting plate bar with a second slide hole, a rod provided below the outer member, a first female screw, and a second female screw. Therefore, even if there is an error in the length of the foot, the angle of the sole can be maintained at a specified angle (the angle of curvature between the horizontal line and the sole is 15 degrees to 25 degrees) and the sole will not slip down.

[0013] The following describes an embodiment of the socks for preventing cramps according to the present invention. The embodiment shows the most preferred embodiment of the invention, and the invention is not limited thereto.

[0014] Fig. 1 is a perspective view of the cramp prevention socks of the present embodiment 1. As shown in Fig. 1, the cramp prevention socks 10 of the present embodiment 1 are provided with a tension section 60 extending from the toes of the knee-high socks 24 to the foot opening section 12 (preferably with rubber built-in: also called the rubber section). The knee-high socks 24 (also called the foot pocket) are made of nylon, cotton, silk, a supporter material, or the like.

[0015] The opening 12 of these knee-high socks 24 is located near the calf when the foot is inserted (the opening is between the foot and the calf below the knee). A strap-like band 15 (also called an opening wrap-around band) is connected to the opening 12, and a band joint 16 (also called simply a part) is connected to this strap-like band 15. The strap-like band 15 is located slightly above the calf.

[0016] In FIG. 1, the portion of the opening 12 extending above the band 15 is described as the upper opening 12a of the sock, and the portion of the opening extending below the band 15 is described as the lower opening 12b of the sock.

[0017] On the other hand, the tension part 60 is plate-shaped, and one end of the lower side is connected to the band joint part 16 of the belt-like band 15, and the other side of the lower side is connected to the tip of the knee socks 24 (long socks) (connected across the front part of the foot except for the vicinity of the button part and the vicinity of the ankle).

[0018] The tensioning part 60 (preferably made of cloth, hard rubber, or the like) is roughly crescent-shaped and is integrated with the knee-high socks 24 by a joining part 40 (adhesive or sewn with thread: adhesive in this embodiment) and tensioning part joining parts 13 (13a, 13b). In FIG. 1, the outside of the foot (the side of the fifth metatarsal bone) is described as the left side.

[0019] The tension portion 60 is connected to the knee-high socks 24 at the left tension portion joint 13a on the outside of the foot and at the right tension portion joint 13b on the inside of the foot (first metatarsal bone side). The left tensile portion joint 13a and the right tensile portion joint 13b are approximately 1 to 2 cm wide and are sewn to the knee socks 24 with thread or the like (which could be adhesive: in this embodiment, they will be described as thread) (the seams are referred to as 14a and 14b).

[0020] The upper side of the joint 40 of the tension part 60 is made strong (like a rope) with adhesive or thread, and this upper side is called tension wire part 42 in this embodiment (it is assumed that the thread is sewn together to make it like a rope). In Fig. 1, the contour line passing through the center of the instep is written as AK (hereinafter, referred to as the front side line AK of the foot).

[0021] Furthermore, buttons 20 (male button 20b, female button 20a: connecting member) are provided at a location near the center of the instep of the knee socks 24 between the tension part joint 13 (left tension part joint 13a, right tension part joint 13b) and the front lateral line AK of the foot. The joint 40 may be one piece, but in this embodiment it is made by attaching two pieces of cloth (nylon material, cotton, etc.) or plastic rubber with a certain degree of hardness. The left side is referred to as the left joint 40a, and the right side is referred to as the right joint 40b.

[0022] 1 shows the button 20 in a closed state. When the button 20 is in a closed state, the knee socks 24 are joined by the tension portion joining portion 13 (left tension portion joining portion 13a, right tension portion joining portion 13b), so there is almost no space in the forefoot portion (first metatarsal to fifth metatarsal) and the opening portion 12, but the knee socks 24 are pulled by the tension portion joining portion 13 (left tension portion joining portion 13a, right tension portion joining portion 13b) and the joining portion 40 of the tension portion 60 and the tension wire portion 42, so a gap is created.

[0023] A bottom plate member 30 is provided on the bottom surface (inside) of the knee-high socks 24. The material of this bottom plate member 30 (also called the inner bottom plate member) is preferably wood, hard rubber, plastic, hardened cork rubber, leather, etc. The bottom plate member 30 may be on the outside of the knee-high socks.

[0024] The bottom plate member 30 is designed so that the angle θp between a straight line LK1 passing through the "calf" edge of the knee socks 24 and the heel tip of the foot, and a straight line LK3 passing near the center of the foot, is 95 degrees to 125 degrees (preferably 110 degrees). Note that in the first embodiment, the knee socks 24 encase the bottom plate member 30, but the knee socks 24 are not shown below the bottom plate member 30 in FIG.

[0025] Next, the belt-like band 15 will be described with reference to Fig. 2. In Fig. 2, the knee socks 24 and the tensioning portion 60 are shown. 2 is a cross-sectional view of the anti-cramp sock 10 as seen from above, with the band 15 in an open state. FIG. 3 is a detailed perspective view of the band joint portion 16 of FIG.

[0026] As shown in Fig. 2, a "calf" side zipper 16d (either one-sided or two-sided: one-sided is preferred) is connected to the knee-high socks 24 above the central part of the "calf". The vertical width is preferably 1cm to 3cm, and the horizontal width is preferably 2cm to 3cm. The "calf" side zipper 16d is also known as Velcro (registered trademark).

[0027] A band-like band 15 is connected to the front side (on the Y axis in Figure 2) of the high socks 24 opposite this "calf" side zipper 16d via band joints 16 (left tension portion joint 13a, right tension portion joint 13b) (see Figure 3). In addition, the left tensile portion joint 13a, the right tensile portion joint 13b, and the lower side surface (approximately 3 mm to 8 mm) of the tensile portion 60 connected to the belt-like band 15 are described as a band joint 16.

[0028] The band 15 shows a cross section of a joint 40 (a left joint 40a, and a right joint 40b on the right side) (connected with adhesive and thread). However, as shown in FIG. 3, the joints 40 (left joint 40a, and the right side thereof, right joint 40b) are coated on the top with a (soft) adhesive or thread (tensile wire portion 42).

[0029] The width of the belt-like band 15 (opening wrap band) is longer than the length that goes around the calf, and is composed of a belt-like band main body 51e, a left back side zipper 51a, a right back side zipper 51b, and a right front side zipper 51c, etc. The side of the belt-like band main body 51e that faces the knee-high socks 24 is called the back side, and the side that faces the tension part 60 is called the front side.

[0030] The left rear side zipper 51a is 3-5cm wide and 1-3cm long, and is sewn to the belt-like band main body 51e from the left end of the rear side of the belt-like band main body 51e with thread (or adhesive).

[0031] The right front side fastener 51c (Magic Tape (registered trademark)) is 3.5 to 7 cm wide and 1 to 3 cm long and is sewn to the right end of the belt-like band main body 51e with thread (or adhesive).

[0032] The right back side zipper 51b is 2.5-3.5cm wide and 1-3cm long, and is sewn to the right end of the back side of the band body 51e with thread (or adhesive).

[0033] (How to wrap) The right back side zipper 51b is connected to the "calf" side zipper 16d, and the left back side zipper 51a is connected to the right front side zipper 51c. This fixes the opening 12 of the knee-high socks 24 to the "calf" of the foot. Therefore, the knee-high socks 24 will not slip down.

[0034] In addition, the "calf" side zipper 16d is 1-3 cm in vertical width and 2-3 cm in horizontal width, so when the left back side zipper 51a, the right back side zipper 51b, and the right front side zipper 51c are removed from the "calf" side zipper 16d, most of the belt-like band 15 comes out of the opening 12 of the knee-high socks 24 as shown in Fig. 2, so that the opening 12 can be easily widened. This makes it easy to put on the socks.

[0035] (size) 4 is a side view of the cramp prevention sock 10 of the present embodiment 1. However, although the knee-high socks 24 are designed to encase the base plate member 30, the knee-high socks 24 are not shown on the back surface of the base plate member 30 in FIG. Furthermore, since the tension portion 60 has the joint portion 40, it supports the tension line portion 42 and pulls it toward the instep when the button 20 is closed.

[0036] 4 shows the line 17 on the instep of the knee-high socks 24 (the distance from the foot is drawn slightly larger). The gap between the line 17 and the button 20 is about 1 cm to 2 cm when closed. In addition, in FIG. 4, the line of the knee-high socks 24 is indicated as M, and the distance between the line 17 and M is indicated as H (no joint).

[0037] Fig. 5 is a cross-sectional view taken along line AA in Fig. 4. Fig. 6 is a front view of the cramp prevention sock 10 when the foot is placed inside and viewed from the front (toe side). In these figures, explanations of the same reference numerals as in Fig. 1 will be omitted. In Fig. 4, 17 is a line on the front side (instep) of the knee-high socks 24. As they are pulled by the tensioning part 60, there is a gap between the foot and the sock (see Fig. 6). However, portions 42 and 13 of the bottom plate member 30 are not shown in FIG.

[0038] The length from the sole of the knee socks 24 to the opening 12 is, for example, 45 cm to 47 cm (for a person with a height of about 170 cm and a foot size of about 26 cm). The button 20 is positioned a little away from the top of the foot.

[0039] Moreover, the angle θp between the straight lines LK1 and LK3 is 95 degrees to 125 degrees (preferably 110 degrees), and the angle θb between the horizontal line LK2 and the straight line LK3 is 15 degrees to 25 degrees.

[0040] As shown in FIG. 5, the distance between the button 20 and the line 17 is about 1 cm to 3 cm.

[0041] (Button Released) Next, the cases where the button 20 is in the open state and the closed state will be described with reference to FIG. 7(a) is an explanatory diagram of the button 20 in an open state, and FIG 7(b) is an explanatory diagram of the button 20 in a closed state, both of which are shown in cross section taken along the line AA in FIG 4. In addition, the button 20 will be described larger than it actually is.

[0042] When the cramp prevention sock 10 is put on and the male button 20b and the female button 20a are mated as shown in FIG. 7(b), the foot is tightened as shown in FIG. 7(b).

[0043] On the other hand, when the male button 20b and the female button 20a are removed, the knee-high socks 24 come apart from the feet, as shown in Fig. 7(a). This makes it easy to put on and take off the knee-high socks.

[0044] (The soles of high socks) Fig. 8 is an explanatory diagram of the sole side of the knee socks. As shown in Fig. 8, the tension part joint 13 (left tension part joint 13a, right tension part joint 13b) is formed around the toes and up to the front of the arch of the foot, and is sewn in with thread (14a, 14b) and bonded with adhesive. Therefore, the tension part 60 will not come off.

[0045] (Explanation of parts A and B in Fig. 1) Fig. 9 is an explanatory diagram of parts A and B in Fig. 1. As shown in Fig. 9(a), the left joint part 40a and the right joint part 40b are bonded with an adhesive. 9(b), the tip of the knee socks 24 is wrapped around the tension part joining parts 13 (left tension part joining part 13a, right tension part joining part 13b) and 42 (however, 43 is omitted). In other words, even if pulled strongly, it will not break.

[0046] (Effect of tension portion 60 and button 20) Fig. 10 is an explanatory diagram of the effect of the pulling portion 60 and the button 20. In Fig. 10, the tip (the other side) of 42 is written as P2, and the other side is written as P1. As shown in Figure 10, when button 20 is closed, 42 is taut, and when button 20 is closed, since joint 40 is somewhat stiff, it is pulled toward the button as indicated by arrow F. This causes 42 to be pulled even further. This causes the sole of the foot to be pulled even further toward the instep.

[0047] When the button 20 is undone, the strap 42 hangs down as shown in Fig. 10(b), making it easy to put on and take off the socks.

[0048] <Embodiment 2> Fig. 11 is a side view of a cramp prevention sock 50 according to embodiment 2. In Fig. 11, the same reference numerals as those described above will not be described. Also, although 30 is wrapped in knee-high socks, this is not shown in Fig. 11. The cramp prevention socks 50 of the second embodiment are bent from near the base of the toes (first metatarsal to fifth metatarsal) of the knee socks 24. The material of this portion 36 is preferably plastic, rubber, or cowhide.

[0049] Therefore, when you put your foot in and close the button 20, the toes are bent from the base, which creates an even greater effect. <Embodiment 3> In the above embodiment, the strap-like band is used to prevent the socks from falling down, but a further reinforcing tool (called a cramp prevention aid) will be described in embodiment 3. Fig. 12 is a side view of the socks for preventing cramps according to the third embodiment. Explanations of the same reference numerals as above will be omitted. Also, 30 is wrapped in knee-high socks, but is not shown wrapped in Fig. 12.

[0050] Moreover, in the third embodiment, knee-high socks are used that have a longer vertical width 12 (rubber part) than the knee-high socks described above. In the embodiment, these knee-high socks are designated as 25. The opening for the foot is designated as 49. The vertical width L10c of the opening 49 is about 8 cm to 10 cm.

[0051] Furthermore, instead of the belt-like band 15 (made of cloth or nylon material), a plastic rubber band 54 (preferably with a vertical width of about 3 cm) is connected to the opening 49. As shown in FIG. 12, one end of the first support bar 52a (there is also a second support bar 52b on the back side) made of plastic rubber is connected to a plastic rubber band 54, and the other end is connected to a button 57a ​​(there is also a button 57b on the back side) at the instep.

[0052] In this embodiment 3, this plastic rubber band 54 (which can also be made of cloth or nylon material), first support bar 52a (there is also a second support bar 52b on the back side), and knee-high socks 25 are collectively referred to as anti-cramp socks 80.

[0053] The first support bar 52a (there is also a second support bar 52b on the reverse side) and the plastic rubber band 54 are collectively referred to as a sagging prevention aid 70. It is preferable that 52a and 52b have a certain degree of hardness.

[0054] Fig. 13 is a perspective view of the sagging prevention aid 70. Fig. 14 is a side view of the knee-high socks 25. Fig. 15 is a cross-sectional view seen from the direction D in Fig. 13.

[0055] As shown in Fig. 14, buttonhole 41 is formed near the instep of knee-high socks 25. The diameter of this buttonhole is about 3mm to 6mm. Additionally, buttonhole seat 45a (with 45b on the back side as well) is attached (with adhesive or sewn with thread) to knee-high socks 25 around buttonhole 41. Additionally, Velcro (registered trademark) 56b, which will be described later, is attached to opening 49.

[0056] As shown in FIG. 15, the plastic rubber band 54 has a length of about half the circumference of the knee-high socks 25, and a Velcro tape (registered trademark) 56a is attached (by thread sewing or adhesive) to the back side of the plastic rubber band 54.

[0057] Also, a Velcro tape (registered trademark) 54 is connected (by thread or adhesive) to the knee socks 25. The adhesive surface of the Velcro tape (registered trademark) 56b is connected to the adhesive surface of the Velcro tape (registered trademark) 56a.

[0058] That is, the plastic rubber band 54 can be removed from the knee socks 25. Also, since the knee socks 25 do not have the plastic rubber band 54 on the "calf" side, even if the user wears the cramp prevention socks 50 and sleeps on their back, there is no discomfort on the calf side. Therefore, sleep is not disturbed.

[0059] On the other hand, as shown in FIG. 13, the sagging prevention aid 70 is formed by sewing one end of the first support bar 52a to one end of the plastic rubber band 54 with thread and then fixing the same with an adhesive. Also, one side of the second support bar 52b is sewn to the other end of the plastic rubber band 54 with thread and fixed with an adhesive.

[0060] Furthermore, the other end of the first support bar 52a is fixed by thread or adhesive to one end of a left button base 58a (made of rubber). This left button base 58a is elliptical, and has a female button 57b fixed to the other end.

[0061] The other end of the second support bar 52b is fixed to one end of a right button base 58b (made of rubber) by thread or adhesive. The right button base 58b is an elongated oval, and has a male button 57a ​​fixed to the other end.

[0062] Therefore, the male button 57a ​​and the female button 57b can be fitted into the connection holes 44 (opened symmetrically on the left and right) shown in FIG. As a result, the knee-high socks 25 do not fall down from the calves, and because they are made of rubber, the rubber plates do not disturb sleep. 54 and 13 of 40 are connected as shown in FIG.

[0063] <Fourth embodiment> In the above embodiments, the leg length from below the knee is described as the standard length, but the leg length from below the knee may vary depending on the person. The fourth embodiment is directed to socks for preventing cramps that can be used for people with different leg lengths from the knee down.

[0064] 16 is a side view of the anti-cramp socks according to embodiment 4. Explanation of the same reference numerals as those mentioned above will be omitted.

[0065] In the fourth embodiment, the sock for preventing cramps is based on the knee socks 24 of the first embodiment, the tensioning portion 60 (jointing portions 40, 42, 13), the bottom plate member 30, and the buttons 20. However, the rubber portion is the opening portion 49 of the third embodiment, and the band is 54. Further, a flat plate 76 (outer bottom plate member) is connected (by thread sewing or adhesive) to the bottom of the bottom plate member 30 (inner bottom plate member).

[0066] And, a right support bar 70a (also on the back side), one end of which is connected to one end of the plastic rubber band 54 and the other end to the flat plate 76, prevents the insertion opening 49 from dropping and allows the height to be adjusted. These support bars (right support bar 70a, left support bar 70b), the flat plate 76, and the plastic rubber band 54 are collectively referred to as the height-adjustable auxiliary tool 90.

[0067] In addition, in this embodiment, a combination of the height-adjustable support device 90, the knee-high socks 24, the tensioning portion 60 (joints 40, 42, 13), the base plate member 30, the buttons 20, etc. is referred to as a height-adjustable cramp prevention sock 80.

[0068] Fig. 17 is a perspective view of a height-adjustable assisting device 90. As shown in Fig. 17, one end of a right support bar 70a (also called the first length-adjusting plate bar) of the height-adjustable assisting device 70 is connected (by thread or adhesive) to the right end of the plastic rubber band 54. Also, one end of a left support bar 70b (also called the second length-adjusting plate bar) is connected to the left end of the plastic rubber band 54.

[0069] The other ends of the right support bar 70a and the left support bar 70b wrap around the rear surface of the flat plate 76 and are connected to the rear surface of the flat plate 76 (by thread or adhesive).

[0070] Furthermore, slide holes 78 (right slide hole 78a, left slide hole 78b) are formed below the right support bar 70a and the left support bar 70b. Note that a scale (in 1 mm units) may be written around the slide holes 78.

[0071] A long rod 80c (preferably made of aluminum) is passed under the flat plate 76, and both ends of the long rod 80c are male-threaded.

[0072] The long rod 80c is fixed via 70a, 70b by a right female screw 80a (the knob portion has a wider width than the right slide hole 78a) and a left female screw 80b (the knob portion has a wider width than the left slide hole 78b).

[0073] In addition, the right side support bar 70a is folded in from one side with a predetermined gap (5 mm to 1 cm: a gap that can at least accommodate 80c and 76) at a location where the other end is near the arch (from the heel side) on the back surface of the outer bottom plate member 76.

[0074] In addition, the left side support bar 70b is folded in from the other side at a location where the other end is near the arch (from the heel side) on the back surface of the outer bottom plate member 76, with a predetermined gap (5 mm to 1 cm: a gap that can at least accommodate 80c and 76). Therefore, even if the leg length from the knee down differs from the standard, adjustment is possible.

[0075] (Other embodiments) Although the button and 40 are not bonded to each other, as shown in FIG. 18, a button base 29 (compressed pulp) may be provided and 40 (40a in FIG. 18) may be connected to this button base 29 (24a in FIG. 18).

[0076] In this way, the open area is reduced, but since the joint 40 (40a, 40b) and the button base 29 are connected, when the button 20 (20a, 20b) is closed, 42 is pulled toward the instep. Furthermore, in the above embodiment, the socks have been described, but the shoes may be formed as cleats made entirely of rubber, with the angle between LK3 and LK1 being 95 degrees to 120 degrees (preferably 110 degrees).
