Summary of the Invention

Problems to be Solved by the Invention

[0004] However, Patent Document 1 did not address preventing slippage between the shoe and foot during quick changes of direction in sports. Furthermore, in the case of socks described in Patent Document 2, there is a need to further improve the slippage between the shoe and foot during quick changes of direction in sports.

[0005] To solve the aforementioned conventional problems, the present invention provides sports socks that can prevent slippage between the shoe and the foot during quick changes of direction in sports. [Means for solving the problem]

[0006] The present invention relates to a sports sock comprising a sock body and an anti-slip portion disposed on the outer surface of the sock body, wherein the anti-slip portion includes a first anti-slip portion disposed on the outer surface of the sole of the sock body in a region covering the area from the ball of the big toe to the ball of the little toe of the forefoot, and the first anti-slip portion includes a plurality of first inner anti-slip portions arranged radially in a fan shape from the origin in the region covering the second, third, and fourth metatarsals in the longitudinal direction, and a plurality of first outer anti-slip portions arranged radially in a fan shape from the origin in the longitudinal direction. [Effects of the Invention]

[0007] Wearing the socks of the present invention can prevent slippage between the shoe and the foot during quick changes of direction in sports. [Brief explanation of the drawing]

[Figure 13] This is a schematic diagram showing the sports sock (left foot) used in Comparative Example 1, laid flat, with the top side viewed from the instep. [Modes for carrying out the invention]

[0009] The inventors have repeatedly studied how to prevent slippage between shoes and feet (socks) during turning movements in sports. As a result, based on the magnitude and direction of the shearing force and the position of the center of foot pressure during these movements, a plurality of first inner anti-slip portions and a plurality of first outer anti-slip portions are respectively provided at predetermined positions on the forefoot portion of the sock in a fan-shaped radial arrangement such that the longitudinal direction is in a predetermined direction, and it has been found that slippage between the shoes and feet during turning movements in sports can be prevented.

[0010] During turning movements in sports, specifically, the magnitude and direction of the shearing force and the center of foot pressure during 45-degree and 180-degree turning movements in soccer were examined. Four experienced subjects were used. As shown in FIG. 8, markers 1 to 8 were attached to predetermined positions of the spikes, and the subjects wore spikes with socks that had no anti-slip properties. The magnitude and direction of the shearing force and the center of foot pressure during the above movements were measured with a ground reaction force meter, and the positions of markers 1 to 8 were measured with a motion capture system. The results are shown in FIGS. 9 and 10. FIGS. 9 and 10 are graphs depicting vectors representing the center of foot pressure and the magnitude and direction of the shearing force every 0.01 seconds. In FIGS. 9 and 10, black circles 1 to 8 respectively indicate markers 1 to 8 attached to the spikes, the direction of the arrow indicates the direction of the ground reaction force (shearing force), and the length of the arrow indicates the magnitude of the ground reaction force (shearing force). As can be seen from FIGS. 9 and 10, during 45-degree and 180-degree turning movements, a large force is applied in the lateral direction (width direction) and the diagonal up-and-down direction to the area covering the ball of the thumb to the ball of the little finger, and the center of foot pressure is concentrated in the area covering the second, third, and fourth metatarsal bones.

[0011] In one or more embodiments, based on the above data, on the front side of the sole of the area covering from the ball of the thumb to the ball of the little finger on the front foot part of the sock body, during the turning motion in sports, especially in the area corresponding to the center of foot pressure during the 45-degree turning motion and the 180-degree turning motion, a first anti-slip part is provided, which consists of a plurality of first inner anti-slip parts and a plurality of first outer anti-slip parts that are radially arranged in a fan shape such that the longitudinal direction is along the horizontal direction (width direction), the obliquely upward direction or the obliquely downward direction, respectively, from the starting part in the area corresponding to the center of foot pressure, towards the inside or the outside. This effectively prevents the slippage between the shoe and the foot during the turning motion in sports. When the foot slips inside the shoe and foot slippage occurs during the turning motion in sports, quick turning cannot be performed, causing a decrease in performance. However, by wearing the sports sock of the present invention, the foot slippage inside the shoe during the turning motion in sports such as soccer, badminton, and tennis can be effectively prevented, and the occurrence of performance degradation can be suppressed. Particularly preferably, the foot slippage inside the shoe during the turning motion in soccer can be effectively prevented, and the occurrence of performance degradation can be suppressed.

[0012] In this specification, the outside corresponds to the little finger side of the foot, the inside corresponds to the thumb side of the foot, the upper part corresponds to the toe side, the lower part corresponds to the heel side, the back side corresponds to the side in contact with the foot, and the front side corresponds to the opposite side of the side in contact with the foot.

[0013] The sports sock includes a sock body and an anti-slip part disposed on the front side of the sock body.

[0014] The sock body includes a foot part and a leg part. The foot part may include a front foot part, a middle foot part, and a rear foot part. The length of the leg part (the length of the leg part or the length from the heel) is not particularly limited. For example, a short type that covers up to the ankle may be used, a middle type that is above the ankle and below the knee may be used, or a long type that is above the knee may be used. In the case of the short type or the middle type, it can be worn in combination with a calf stocking (also referred to as a separate type).

[0015] In the forefoot portion of the sock body, the toe area may be a normal type where the toes are not separated, but from the viewpoint of making it easier for the foot to grip during sports activities, it may also be a tabi type where the big toe is separated or a five-toe type where all five toes are separated.

[0016] The sock body is preferably made of fiber yarn containing elastic yarn from the viewpoint of elasticity. The elastic yarn preferably includes at least one selected from the group consisting of polyurethane elastic yarn and polyester elastic yarn, because it has high stretchability and is suitable for socks. The elastic yarn may be used as bare yarn, held together with non-elastic yarn (rigid yarn), or as covered yarn, with polyester fiber, nylon fiber, acrylic fiber, wool, cotton, etc., covering the surface.

[0017] The anti-slip portion includes an anisotropic first anti-slip portion positioned on the upper surface of the sole of the sock body in the area covering the forefoot from the ball of the big toe to the ball of the little toe. In this specification, "anisotropic" means that the anti-slip portion has a longitudinal direction and a width direction perpendicular to the longitudinal direction, rather than an isotropic shape. The planar shape of the anti-slip portion may be anisotropic and is not particularly limited, and examples include quadrilaterals, pentagons, hexagons, and irregular shapes.

[0018] The first anti-slip portion includes a plurality of anisotropic first medial anti-slip portions arranged radially in a fan shape from the origin in the region covering the second, third, and fourth metatarsals in the longitudinal direction. As a result, the first ends of all of the plurality of anisotropic first medial anti-slip portions are located at the origin corresponding to the center of pressure during quick changes of direction in sports, and the longitudinal direction of the plurality of anisotropic first medial anti-slip portions corresponds to the direction of the shear force during quick changes of direction in sports, thereby effectively preventing foot slippage inside the shoe during quick changes of direction in sports.

[0019] The first inner anti-slip section can consist of multiple pieces and is not particularly limited, but may consist of two or more pieces, or three or more pieces. From the viewpoint of suppressing foot slippage inside the shoe during quick changes of direction in sports, effectively preventing foot displacement, and improving wearability, it may consist of 2 to 10 pieces, 2 to 8 pieces, or 3 to 6 pieces.

[0020] Each of the first inner anti-slip sections may branch into two or more or two to four sections midway, from the viewpoint of maintaining the elasticity of the sock body, and each branch may be divided into two or more or two to six sections in the longitudinal direction. Furthermore, each of the first inner anti-slip sections may have a constant width along its entire length, or its width may vary. For example, each of the first inner anti-slip sections may have the smallest width at the first end located at the starting point, and the width may increase towards the inside.

[0021] The first inner anti-slip portion preferably includes a first inner lower anti-slip portion, which has one or more longitudinal directions arranged diagonally from the starting portion toward the inner lower portion, and a first inner upper anti-slip portion, which has one or more longitudinal directions arranged diagonally from the starting portion toward the inner upper portion, in order to more effectively suppress foot slippage inside the shoe during quick changes of direction in sports and prevent foot displacement. The first inner anti-slip portion may also include a first inner lateral anti-slip portion, which has one or more longitudinal directions arranged along the width direction toward the inner portion from the starting portion.

[0022] The first anti-slip portion also includes a plurality of anisotropic first outer anti-slip portions arranged radially in a fan shape from the starting portion in the longitudinal direction. As a result, all of the first ends of the plurality of anisotropic first outer anti-slip portions are located at the starting portion corresponding to the center of foot pressure during quick changes of direction in sports, and the longitudinal direction of the plurality of anisotropic first outer anti-slip portions corresponds to the direction of the shear force during quick changes of direction in sports, thereby effectively preventing foot slippage inside the shoe during quick changes of direction in sports.

[0023] The first outer anti-slip section can consist of multiple strips and is not particularly limited; however, it may consist of two or more strips, or three or more strips. From the viewpoint of suppressing foot slippage inside the shoe during quick changes of direction in sports, effectively preventing foot displacement, and improving wearability, it may consist of 2 to 10 strips, 2 to 8 strips, or 3 to 6 strips.

[0024] Each of the first outer anti-slip sections may branch into two or more or two to four sections midway, from the viewpoint of maintaining the elasticity of the sock body, and each branch may be divided into two or more or two to six sections in the longitudinal direction. Furthermore, each of the first outer anti-slip sections may have a constant width along its entire length, or its width may vary. For example, each of the first outer anti-slip sections may have the smallest width at the first end located at the starting point, and the width may increase towards the outside.

[0025] The first outer anti-slip portion preferably includes a first outer lower anti-slip portion, which has one or more longitudinal directions arranged diagonally from the starting portion toward the outer lower part, and a first outer lateral anti-slip portion, which has one or more longitudinal directions arranged along the width direction toward the outside from the starting portion, in order to more effectively suppress foot slippage inside the shoe during quick changes of direction in sports and prevent foot displacement. The first outer anti-slip portion may further include a first outer upper anti-slip portion, which has one or more longitudinal directions arranged diagonally from the starting portion toward the outer upper part.

[0026] When the first inner anti-slip portion is divided into two or three sections by imaginary lines at equal intervals in the longitudinal direction, it is preferable that the area of ​​each section increases from the starting point towards the inner end, and when the first outer anti-slip portion is divided into two or three sections by imaginary lines at equal intervals in the longitudinal direction, it is preferable that the area of ​​each section increases from the starting point towards the outer end. This makes it possible to more effectively suppress foot slippage inside the shoe during quick changes of direction in sports and prevent foot displacement.

[0027] Alternatively, it is preferable that the area of ​​the first medial anti-slip portion in the region covering the first metatarsal bone is larger than the area of ​​the first medial anti-slip portion in the region covering the second metatarsal bone, and that the area of ​​the first lateral anti-slip portion in the region covering the fifth metatarsal bone is larger than the area of ​​the first lateral anti-slip portion in the region covering the fourth metatarsal bone. This makes it possible to more effectively suppress foot slippage inside the shoe during quick changes of direction in sports and prevent foot displacement.

[0028] Specifically, when the origins of the first medial anti-slip portion and the first lateral anti-slip portion are located in the region covering the diaphysis of the third metatarsal bone, it is preferable that the area of ​​the first medial anti-slip portion is larger in the order of the region covering the third metatarsal bone, the second metatarsal bone, and the first metatarsal bone, and that the area of ​​the first lateral anti-slip portion is larger in the order of the region covering the third metatarsal bone, the fourth metatarsal bone, and the fifth metatarsal bone.

[0029] The anti-slip portion further includes one or more anisotropic second anti-slip portions located in the center of the upper surface of the instep side of the area covering from the medial malleolus to the lateral malleolus, and it is preferable that the longitudinal direction of the second anti-slip portion is aligned with the width direction of the foot. By having the second anti-slip portion in a position corresponding to the tongue of the sports shoe in this way, it is possible to prevent the tongue of the sports shoe from shifting during sports play.

[0030] The anti-slip portion further includes multiple, for example, two or more, 2 to 6 anisotropic third anti-slip portions arranged on the upper surface of the sole of the toe portion of the sock body, wherein the longitudinal direction of the third anti-slip portion is preferably aligned with the length of the foot. It is even more preferable that multiple, for example, two or more, 2 to 6 anisotropic third anti-slip portions are arranged at locations corresponding to the first, second, third, fourth, and fifth toes, with their longitudinal direction aligned with the length of the foot. In sports activities, a force in the length of the foot is applied to the toe portion during the final push-off phase of acceleration. By providing the third anti-slip portion on the toe portion of the sock body with its longitudinal direction aligned with the length of the foot, it is possible to prevent the foot from slipping inside the shoe during the final push-off phase of acceleration, thereby suppressing a decline in performance.

[0031] The anti-slip portion further includes a plurality of anisotropic fourth anti-slip portions arranged on the upper surface of the sole of the rear foot portion of the sock body, wherein the longitudinal direction of the fourth anti-slip portion is preferably aligned with the length of the foot. The fourth anti-slip portion may include 2 to 4 long fourth central anti-slip portions arranged in the center of the upper surface of the sole of the rear foot portion of the sock body, and 3 to 10 fourth left anti-slip portions and fourth right anti-slip portions arranged on both the left and right sides, respectively. Furthermore, each of the fourth left anti-slip portion and the fourth right anti-slip portion may be divided into two or more in the longitudinal direction. In sports movements, a force in the length of the foot is applied to the heel during the initial ground contact phase of stopping and kicking movements. By providing the fourth anti-slip portion on the rear foot portion of the sock body with its longitudinal direction aligned with the length of the foot, it is possible to prevent the foot from slipping inside the shoe during the initial ground contact phase of stopping and kicking movements, thereby suppressing a decrease in performance.

[0032] In the case of a mid-length sock that extends above the ankle and below the knee, it is preferable that the anti-slip portion includes a fifth anti-slip portion located on the upper surface of the area above the heel, extending from the heel to the upper end of the leg portion. This prevents the calf stockings from slipping down when the sports socks of the present invention are worn as a separate type of sock in combination with calf stockings. From the viewpoint of more effectively preventing the calf stockings from slipping down, it is preferable that the fifth anti-slip portion is located on more than half of the total length of the leg portion. The fifth anti-slip portion may also be located on the upper surface of the central part in the width direction above the heel, extending from the heel to the upper end of the leg portion.

[0033] The anti-slip portion is preferably made of resin. The resin is not particularly limited, and for example, an elastic resin can be used. Examples of elastic resins include polyurethane, silicone resin, polyvinyl chloride, polyamide elastomer, polyester elastomer, rubber elastomer, olefin elastomer, polyethylene, polypropylene, nylon, EVA resin (ethylene-vinyl acetate copolymer), ABS resin (acrylonitrile-butadiene-styrene copolymer), and acrylic resin.

[0034] A non-slip area can be formed on a predetermined area on the upper side of the foot or leg portion of the sock body by, for example, applying these resin materials in a flowable state (e.g., liquid) using a printing method, heating, and curing.

[0035] The thickness of the anti-slip portion is not particularly limited and may be set as appropriate. For example, from the viewpoint of fit and barefoot feel, the thickness of the first anti-slip portion, the third anti-slip portion, and the fourth anti-slip portion may be 100 to 300 μm or 400 to 600 μm.

[0036] When the first anti-slip portion is made of resin, it is preferable that when the first inner anti-slip portion is divided into two or three sections by imaginary lines at equal intervals in the longitudinal direction, the resin area of ​​the section closest to the inner end is larger than the resin area of ​​the section closest to the starting point, and when the first outer anti-slip portion is divided into two or three sections by imaginary lines at equal intervals in the longitudinal direction, the resin area of ​​the section closest to the outer end is larger than the resin area of ​​the section closest to the starting point. This makes it possible to more effectively suppress foot slippage inside the shoe during quick changes of direction in sports and prevent foot displacement.

[0037] Alternatively, if the first anti-slip portion is made of resin, it is preferable that the resin area of ​​the first medial anti-slip portion in the region covering the first metatarsal bone is larger than the resin area of ​​the first medial anti-slip portion in the region covering the second metatarsal bone, and that the resin area of ​​the first lateral anti-slip portion in the region covering the fifth metatarsal bone is larger than the resin area of ​​the first lateral anti-slip portion in the region covering the fourth metatarsal bone. This makes it possible to more effectively suppress foot slippage inside the shoe during quick changes of direction in sports and prevent foot displacement.

[0038] Specifically, when the origins of the first medial anti-slip portion and the first lateral anti-slip portion are located in the region covering the diaphysis of the third metatarsal bone, it is preferable that the resin area of ​​the first medial anti-slip portion is larger in the region covering the third metatarsal bone, the second metatarsal bone, and the first metatarsal bone, in that order, and the resin area of ​​the first lateral anti-slip portion is larger in the region covering the third metatarsal bone, the fourth metatarsal bone, and the fifth metatarsal bone, in that order.

[0039] When the anti-slip portion is made of resin, from the viewpoint of suppressing a decrease in the elasticity of the sock body and not hindering the fit, the resin area ratio of the first, second, third, or fourth anti-slip portion is preferably 15 to 85%, more preferably 35 to 65%, and the resin area ratio of the fifth anti-slip portion is preferably 10 to 70%, more preferably 20 to 50%. In this specification, the resin area ratio of the anti-slip portion indicates the ratio of the resin area to the area of ​​the anti-slip portion in the area where the anti-slip portion is located, and the area of ​​the anti-slip portion refers to the area surrounded by the outer circumference of the anti-slip portion located on the sock body.

[0040] From the viewpoint of further enhancing the fit and barefoot feel, it is preferable that the aforementioned sports socks do not have a non-slip part made of resin on the sole of the midfoot portion of the sock body.

[0041] The aforementioned sports socks can be manufactured using a sock knitting machine such as a five-finger sock knitting machine. For example, the knitting structure of the forefoot may be smooth knit, jersey knit, and pile knit, the knitting structure of the midfoot may be rib knit, elastic knit, and jersey knit, the knitting structure of the rearfoot may be smooth knit, jersey knit, and pearl knit, and the knitting structure of the leg may be jersey knit, smooth knit, and elastic knit.

[0042] Embodiments of the present invention will be described in detail below with reference to the drawings. In each drawing, the same reference numerals indicate the same parts. However, the present invention is not limited to the embodiments shown in the drawings below. Also, the drawings below describe a sock for the left foot, and since the sock for the right foot is symmetrical to the sock for the left foot, the description of the sock for the right foot is omitted.

[0044] The sports sock 10 of Embodiment 1 is a five-finger type and includes a sock body 11 and an anti-slip portion 12 located on the outer side of the sock body 11.

[0045] The anti-slip portion 12 includes an anisotropic first anti-slip portion 130 positioned on the upper side of the sole of the sock body in the area covering the forefoot from the ball of the big toe to the ball of the little toe. The first anti-slip portion 130 consists of three first medial anti-slip portions 131 (131a, 131b, 131c) arranged radially in a fan shape from the origin in the area covering the second, third, and fourth metatarsals, and a plurality of first lateral anti-slip portions 132 (132a, 132b, 132c) whose longitudinal direction is arranged radially in a fan shape from the origin outward.

[0047] The first inner lower anti-slip sections 131a, 131b and the first inner upper anti-slip section 131c all branch into two branches midway, and each branch is divided into three in the longitudinal direction. Furthermore, the width of the first inner lower anti-slip sections 131a, 131b and the first inner upper anti-slip section 131c is not constant along its entire length, with the width being smallest at the first end located at the starting point and increasing towards the inside.

[0048] Specifically, the first lateral anti-slip portion 132 consists of two first lateral inferior anti-slip portions 132a and 132b, whose longitudinal directions are arranged diagonally from the origin corresponding to the shaft of the third metatarsal bone toward the lateral inferior part, and a first lateral lateral anti-slip portion 132c, whose longitudinal direction is arranged along the width direction toward the lateral part toward the lateral part.

[0049] The first outer lower anti-slip sections 132a and 132b both branch into two branches midway, and each branch is divided into three in the longitudinal direction. The first outer lateral anti-slip section 132c is divided into two in the longitudinal direction. The width of the first outer lower anti-slip sections 132a, 132b, and the first outer lateral anti-slip section 132c is not constant along its entire length, with the width being smallest at the first end located at the starting point and increasing towards the outside.

[0050] The anti-slip portion 12 includes a single anisotropic second anti-slip portion 140 positioned in the center of the upper surface on the instep side of the area covering from the medial malleolus to the lateral malleolus. The longitudinal direction of the second anti-slip portion 140 is aligned with the width direction of the foot. The second anti-slip portion 140 only needs to have an anisotropic shape, and its shape is not particularly limited.

[0052] The sports sock 20 of Embodiment 2 is a five-finger type and, like the sports sock 10 of Embodiment 1, includes a sock body 11 and an anti-slip portion 12 located on the outer side of the sock body 11. The anti-slip portion 12 includes a first anti-slip portion 130 and a second anti-slip portion 140. A redundant explanation of the same configuration as the sports sock 10 of Embodiment 1 will be omitted.

[0060] Figures 5 and 6 are schematic diagrams of the forefoot portion of the sports sock of the present invention, viewed from the sole side with the upper side facing outwards, when the sock is laid flat. As shown in Figure 5, when the first inner anti-slip portion 131 is divided into two sections 210 and 220 by dotted lines at equal intervals in the longitudinal direction, the area of ​​the sections increases in the order of 220 and 210 as you move inward from the starting point. Specifically, the area of ​​section 210, which is closer to the inside, is larger than the area of ​​section 220, which is closer to the starting point. Similarly, when the first outer anti-slip portion 132 is divided into two sections 310 and 320 by dotted lines at equal intervals in the longitudinal direction, the area of ​​the sections increases in the order of 320 and 310 as you move outward from the starting point. Specifically, the area of ​​section 310, which is closer to the outside, is larger than the area of ​​section 320, which is closer to the starting point. As shown in Figure 6, when the first inner anti-slip portion 131 is divided into three sections 410, 420, and 430 by dotted lines at equal intervals in the longitudinal direction, the area of ​​each section increases in the order of 430, 420, and 410 as you move inward from the starting point. Specifically, section 410 has the largest area, and section 430 has the smallest area. Similarly, when the first outer anti-slip portion 132 is divided into three sections 510, 520, and 530 by dotted lines at equal intervals in the longitudinal direction, the area of ​​each section increases in the order of 530, 520, and 510 as you move outward from the starting point. Specifically, section 510 has the largest area, and section 530 has the smallest area.

[0061] In Figures 5 and 6, the first inner anti-slip portion 131 and the first outer anti-slip portion 132 are made of resin. As shown in Figures 5 and 6, when the first inner anti-slip portion is divided into two or three sections by dotted lines at equal intervals in the longitudinal direction, the resin area of ​​section 210 or 410 closest to the inner end is larger than the resin area of ​​section 220 or 430 closest to the starting point. Also, as shown in Figures 5 and 6, when the first outer anti-slip portion 132 is divided into two or three sections by dotted lines at equal intervals in the longitudinal direction, the resin area of ​​section 310 or 510 closest to the outer end is larger than the resin area of ​​section 320 or 530 closest to the starting point.

[0062] Furthermore, as shown in Figures 5 and 6, the area of ​​the first medial anti-slip portion in the region covering the first metatarsal bone is larger than the area of ​​the first medial anti-slip portion in the region covering the second metatarsal bone, and the area of ​​the first lateral anti-slip portion in the region covering the fifth metatarsal bone is larger than the area of ​​the first lateral anti-slip portion in the region covering the fourth metatarsal bone. Specifically, the origins of the first medial anti-slip portion 131 and the first lateral anti-slip portion 132 are located in the region covering the shaft of the third metatarsal bone. The area of ​​the first medial anti-slip portion 131 is larger in the region covering the third metatarsal bone, the second metatarsal bone, and the first metatarsal bone, in that order, while the area of ​​the first lateral anti-slip portion 132 is larger in the region covering the third metatarsal bone, the fourth metatarsal bone, and the fifth metatarsal bone. This makes it possible to more effectively suppress foot slippage inside the shoe during quick changes of direction in sports and prevent foot displacement.

[0063] Specifically, it is preferable that the first anti-slip portion is made of resin, the resin area of ​​the first medial anti-slip portion 131 in the region covering the first metatarsal bone is larger than the resin area of ​​the first medial anti-slip portion 131 in the region covering the second metatarsal bone, and the resin area of ​​the first lateral anti-slip portion 132 in the region covering the fifth metatarsal bone is larger than the resin area of ​​the first lateral anti-slip portion 132 in the region covering the fourth metatarsal bone. More specifically, the origins of the first medial anti-slip portion 131 and the first lateral anti-slip portion 132 are located in the region covering the shaft of the third metatarsal bone. The resin area of ​​the first medial anti-slip portion is largest in the region covering the third metatarsal bone, the second metatarsal bone, and the first metatarsal bone, in that order. The resin area of ​​the first lateral anti-slip portion 132 is largest in the region covering the third metatarsal bone, the fourth metatarsal bone, and the fifth metatarsal bone, in that order.

[0064] Figure 7 is a schematic perspective view of a sports sock (left foot) wearing one embodiment of the present invention (Embodiment 3). When playing sports such as soccer while wearing the sports sock 30 of Embodiment 3, the first anti-slip portion 130 consists of three first inner anti-slip portions 131 (131a, 131b, and 131c) arranged radially in a fan shape from the origin in the region covering the shaft of the third metatarsal bone in the longitudinal direction, and three first outer anti-slip portions 132 (132a, 132b, and 132c) arranged radially in a fan shape from the origin in the longitudinal direction, which effectively prevents the foot from slipping inside the shoe during quick changes of direction in sports such as soccer. In addition, the presence of a second anti-slip portion 140 prevents the tongue of sports shoes such as cleats from slipping when playing sports such as soccer. Furthermore, the presence of the third anti-slip portion 150 prevents the foot from slipping inside the shoe during the final push-off phase of acceleration in sports such as soccer, thereby suppressing a decline in performance. Additionally, the presence of the fourth anti-slip portion 160 prevents the foot from slipping inside the shoe during the initial ground contact phase of stopping and kicking movements in sports such as soccer, thereby suppressing a decline in performance. Furthermore, by having the fifth anti-slip portion 170, when the sports sock 30 is worn as a separate type of sock in combination with a calf stocking (not shown), it is possible to prevent the calf stocking from slipping down. [Examples]

[0065] The following describes embodiments of the present invention, but the present invention is not limited to these embodiments.

[0066] (Example 1) (1) Making the sock <Yarn used> The yarn used in the socks of this embodiment consists of three types: Caliculo® Eco (100% polyester, Teijin Frontier Co., Ltd.) as the outer yarn, Filament Twist Yarn (FTY) (polyurethane: 30 denier, polyester 75 denier) as the inner yarn, and Double Covered Yarn (DCY) (polyurethane: 360 denier, polyester 75 denier) as the elastic yarn. The outer and inner yarns make up the entire sock, while the elastic yarn makes up the midfoot and leg portions. <Organization method> The knitting structure consisted of smooth knit for the forefoot, rib knit for the midfoot, smooth knit for the rearfoot, and jersey knit for the leg, and a five-finger type sock body 11 (size: for 26cm, weight per sock: 27.8g) was produced as shown in Figure 4. (2) Formation of anti-slip section Silicone resin was applied to the upper surface of predetermined areas of the sock body 11 by printing, heated, and cured to form a first anti-slip section 130 consisting of a first inner anti-slip section 131 (131a, 131b, and 131c) and a first outer anti-slip section 132 (132a, 132b, and 132c), a third anti-slip section 150, and a fourth anti-slip section 160, as shown in Figure 3. A second anti-slip section was formed as shown in Figure 2, and a fifth anti-slip section 170 was formed as shown in Figure 4, thereby obtaining the sock 10. The thickness of the first inner anti-slip section 131 is 400 μm, and its area is 8 cm². 2 The resin area ratio is 50.4%, the thickness of the first outer anti-slip portion 132 is 400 μm, and the area is 6.1 cm². 2 The resin area ratio is 52.2%, the thickness of the second anti-slip section 140 is 200 μm, and the area is 3.7 cm². 2 The resin area ratio is 95.3%, the thickness of the third anti-slip part 150 is 400 μm, and the area is 5.1 cm². 2 The resin area ratio is 64.2%, the thickness of the fourth anti-slip section 160 is 400 μm, and the area is 10.2 cm². 2 The resin area ratio is 50%, the thickness of the fifth anti-slip part 170 is 400 μm, and the area is 20 cm². 2 The resin area ratio was 35.2%. In the sock 10, the origins of the first medial anti-slip portion 131 and the first lateral anti-slip portion 132 are located in the region covering the shaft of the third metatarsal bone. The resin area of ​​the first medial anti-slip portion is largest in the region covering the third metatarsal bone, the second metatarsal bone, and the first metatarsal bone, in that order. The resin area of ​​the first lateral anti-slip portion 132 is largest in the region covering the third metatarsal bone, the fourth metatarsal bone, and the fifth metatarsal bone, in that order. The sock for the right foot was made in the same way. The sock for the right foot is symmetrical to the sock for the left foot.

[0067] (Comparative Example 1) ZeroGlide short socks (five-finger type) manufactured by Mizuno Corporation were used. As shown in Figures 12 and 13, the ZeroGlide short socks include an anti-slip section 410 that is positioned so that the longitudinal direction is diagonally downward along the entire upper surface of the sole covering the area from the ball of the big toe to the little toe of the forefoot of the sock body, multiple anti-slip sections 420 that are positioned so that the longitudinal direction is diagonally downward along the upper surface of the sole of the toes, multiple anti-slip sections 430 that are positioned so that the longitudinal direction is diagonally upward along the upper surface of the sole of the rearfoot, an anti-slip section 440 that is positioned so that the longitudinal direction is diagonally downward along the upper surface of the instep of the forefoot, and a single anisotropic anti-slip section 450 positioned in the center of the upper surface of the instep covering the area from the medial malleolus to the lateral malleolus.

[0068] Four healthy male subjects wore the socks of Example 1 and Comparative Example 1, respectively, and performed 45-degree turns (turning direction by 45 degrees) and 180-degree turns (turning direction by 180 degrees) five times each. The foot slippage inside the spikes during the 45-degree and 180-degree turns was measured as follows. The results are shown in Table 1 below.

[0069] (Foot slippage) As shown in Figure 11, a marker 600 that follows the spike was attached to the toe of the spike, and a hole was made in the outer part of the forefoot of the spike corresponding to the MP joint, and a marker 700 was attached to the sock through this hole. Foot slippage was calculated as the difference between the minimum and maximum distances between marker 600 and marker 700 in the contact zone. The change in distance between marker 600 and marker 700 during a 45-degree change of direction movement in soccer was measured. Five measurements were taken for each subject, and the average of these five measurements was used as the foot displacement during the 45-degree change of direction movement. The change in distance between markers 600 and 700 after a 180-degree change of direction in soccer was measured. Five measurements were taken, and the average of these five measurements was used as the foot displacement during the 180-degree change of direction.

[0070] [Table 1]

[0071] As can be seen from the results in Table 1 above, when wearing the socks of Example 1, foot slippage inside the spikes is suppressed during quick changes of direction in sports, specifically during both 45-degree and 180-degree changes of direction, compared to when wearing the socks of Comparative Example 1.
