Detailed Embodiments

[0025] [Description of Embodiments of the Present Invention] First, the embodiments of the present invention are listed and described.

[0026] [1]A sock, wherein on the outer side of the sock bottom surface that comes into contact with the plantar surface of the sock wearer when the sock is worn, and / or on the inner side, which is the opposite side of the outer side of the sock bottom surface, there is an anti-slip portion, the anti-slip portion includes a first anti-slip portion that is formed on the outer side and / or the inner side of the sock bottom surface along the direction of the plantar aponeurosis in the sole of the foot.

[0027] Figure 11 The plantar aponeurosis f1 in the sole of the foot shown in (a) among them is a ligament related to the entire sole of the foot and has the function of obtaining the balance of foot movement. The anti-slip portion in the sock described in the above [1] includes a first anti-slip portion that is formed on the outer side and / or the inner side of the sock bottom surface along the direction of the plantar aponeurosis in the sole of the foot. Therefore, according to the sock described in the above [1], the force of the ligament related to the movement of the foot of the sock wearer during movement can be efficiently transmitted to the ground.

[0028] The sock [2] is the sock described in [1], wherein, The anti-slip portion further includes a second anti-slip portion, which is formed on the outer side and / or the inner side of the bottom surface of the sock along the direction of the plantar long ligament in the sole of the foot.

[0029] In Figure 11 in (b) and Figure 12 in (a) shown in the sole of the foot, the plantar long ligament f2 is connected (attached) to the flexor hallucis brevis f3, adductor hallucis (oblique head) f4, flexor digiti minimi brevis f5, opponens digiti minimi f6, peroneus brevis f7, which are important in transmitting kinetic energy backward when the sole of the foot contacts the ground during walking and running (refer to Figure 12 in (b) to Figure 12 in (f)). These are closely related to the composition and stability of the longitudinal arch (arch cover of the sole of the foot) of the foot. The anti-slip portion in the sock described in the above [2] further includes a second anti-slip portion, which is formed on the outer side and / or the inner side of the bottom surface of the sock along the direction of the plantar long ligament in the sole of the foot. Therefore, in the sock described in the above [2], the thickness increase caused by the second anti-slip portion formed on the region corresponding to the plantar long ligament in the outer side and / or the inner side of the bottom surface of the sock can produce the effect of raising the arch of the foot, and thus can improve the stability of the longitudinal arch of the foot. Further, in the sock described in the above [2], by improving the stability of the longitudinal arch, the movement of the prospective muscle group can also be improved. Therefore, according to the sock described in the above [2], the force of the ligament related to the movement of the foot of the sock wearer during movement can be transmitted to the ground more efficiently.

[0030] The sock [3] is the sock described in [2], wherein, The thickness of the second anti-slip portion is thicker than the thickness of the first anti-slip portion, or, The thickness of the portion of the bottom surface of the sock where the second anti-slip portion is formed is thicker than the thickness of the periphery of this portion of the bottom surface of the sock.

[0031] In the sock described in [3] above, when the thickness of the second anti-slip part is configured to be thicker than that of the first anti-slip part, the above-mentioned effect of lifting the arch of the foot by the second anti-slip part with thickness is enhanced, and the stability of the longitudinal arch of the foot can be further improved. On the other hand, in the sock described in [3] above, when the thickness of the part of the sock bottom surface where the second anti-slip part is formed is configured to be thicker than the thickness of the periphery of this part of the sock bottom surface, even when the thickness of the second anti-slip part is formed to be the same as that of the first anti-slip part, the part of the sock bottom surface where the second anti-slip part is formed also has a thickness. Therefore, the above-mentioned effect of lifting the arch of the foot caused by the second anti-slip part is enhanced, and the stability of the longitudinal arch of the foot can be further improved. Therefore, according to the sock described in [3] above, the effect of the sock described in [2] above can be consolidated.

[0032] [4] is the sock according to any one of [1] to [3], wherein, The anti-slip part further includes a third anti-slip part, which is formed on the outer side and / or the inner side of the sock bottom surface along the direction of the superficial transverse metatarsal ligament in the sole of the foot.

[0033] Figure 13 The superficial transverse metatarsal ligament f8 in the sole of the foot shown is connected to the adductor hallucis (transverse head) f9, and has the function of maintaining the transverse arch of the foot that is indispensable for the movement from the big toe to the little toe of the foot. The plurality of anti-slip parts in the sock described in [4] above further includes a third anti-slip part, which is formed on the outer side and / or the inner side of the sock bottom surface along the direction of the superficial transverse metatarsal ligament in the sole of the foot. Therefore, in the sock described in [4] above, a force that pushes the superficial transverse metatarsal ligament upward to the dorsal side of the foot is generated by the reaction force caused by the third anti-slip part. As a result, the transverse arch of the foot is maintained and all the toes can be easily extended, and the toes can firmly grasp the ground. Therefore, according to the sock described in [4] above, the force of the ligament related to the movement of the foot of the sock wearer during exercise can be further efficiently transmitted to the ground.

[0034] [5] is the sock according to any one of [1] to [4], wherein, The anti-slip part further includes a fourth anti-slip part, which is formed on the outer side and / or the inner side of the sock bottom surface in such a way as to sandwich the sesamoid bone position corresponding to the sesamoid bone in the big toe of the sock wearer from the front and back directions of the sock.

[0035] Figure 14 in (a) and Figure 15The sesamoid bone f10 in the big toe shown in (a) in [ ] has the function of a pulley for the tendon, making the activities of joints and ligaments flexible. The multiple anti-slip portions in the sock described in the above [5] further include a fourth anti-slip portion, which is formed on the outer side and / or the inner side of the bottom surface of the sock in such a way as to sandwich the position of the sesamoid bone corresponding to the big toe of the sock wearer in the front-back direction of the sock. Therefore, according to the sock described in the above [5], through the fourth anti-slip portion, the sesamoid bone in the big toe is sandwiched in the front-back direction of the sock and is stabilized, and the function of the sesamoid bone is improved. Therefore, according to the sock described in the above [5], the force of the ligament related to the movement of the foot of the sock wearer can be efficiently transmitted to the ground. In addition, according to the sock described in the above [5], the effect of preventing sesamoiditis and the like can also be expected.

[0036] [6] is the sock described in any one of [1] to [5], wherein, The sock has a non-formed anti-slip area where the anti-slip portion is not formed in the area corresponding to the instep arch cover of the sole on the outer side and / or the inner side of the bottom surface of the sock.

[0037] As Figure 16 shown, the position where the tendons (flexor digitorum longus f12 and flexor hallucis longus f13) of the instep arch cover of the sole cross. When this position is pressed, the movement of the foot is restricted. In the sock described in the above [6], there is a non-formed anti-slip area where the anti-slip portion is not formed in the area corresponding to the instep arch cover of the sole on the outer side and / or the inner side of the bottom surface of the sock. Therefore, in the sock described in the above [6], due to the existence of the non-formed anti-slip area, the position where the tendons cross is difficult to be pressed by the anti-slip portion. Therefore, according to the sock described in the above [6], the force of the ligament related to the movement of the foot of the sock wearer can be efficiently transmitted to the ground.

[0038] [7] is the sock described in any one of [1] to [6], wherein, The area of the sock corresponding to the extensor retinaculum inferior and fibular retinaculum inferior of the foot of the sock wearer has a first woven belt portion formed by a woven belt.

[0039] Figure 17 As shown, the extensor retinaculum inferior f14 and fibular retinaculum inferior f15 of the foot have the function of lifting the longitudinal arch of the foot from above. The area of the sock described in the above [7] corresponding to the extensor retinaculum inferior and fibular retinaculum inferior of the foot of the sock wearer has a first woven belt portion formed by a woven belt. Therefore, according to the sock described in the above [7], the extensor retinaculum inferior and fibular retinaculum inferior of the foot are protected by the first woven belt portion, and the stability of the longitudinal arch of the foot can be improved. Therefore, according to the sock described in the above [7], the force of the ligament related to the movement of the foot of the sock wearer can be transmitted to the ground more efficiently.

[0040] [8] The sock according to [7], wherein, the sock has a second knitted band portion that extends from the first knitted band portion and is formed of a knitted band, the second knitted band portion is formed in a region corresponding to the following path: from the extensor retinaculum of the foot of the sock wearer, passing above the lateral malleolus of the foot of the sock wearer, surrounding the lateral head of the calcaneal tendon of the sock wearer, and returning to the extensor retinaculum through above the medial malleolus of the foot of the sock wearer.

[0041] When a contusion occurs in a human foot joint, it is mostly injured by inversion. The sock described in [8] above has, in addition to the first knitted band portion, the second knitted band portion described above. Therefore, according to the sock described in [8] above, the formation of the longitudinal arch of the foot caused by the first knitted band portion is promoted, and it is easy to inhibit the inversion of the foot joint. On this basis, the second knitted band portion is configured to remove the calcaneal tendon attachment portion that is active during the movement of the sock wearer and keep the end point slightly toward the head side, so it is also difficult to interfere with the movement of the calcaneal tendon itself.

[0042] [9] The sock according to any one of [1] to [8], wherein, the toe portion at the front end of the sock is formed in a round head shape that covers the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer together, or, the toe portion at the front end of the sock is formed in a sock shape that separately covers the thumb, and the index finger, middle finger, ring finger, and little finger of the foot of the sock wearer, or, the toe portion at the front end of the sock is formed in a four-fork shape that separately covers the thumb, index finger, middle finger, and the ring finger and little finger of the foot of the sock wearer, or, the toe portion at the front end of the sock is formed in a five-finger shape that separately covers the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer.

[0043] In the sock described in [9], when the toe portion at the front end of the sock is formed in a round head shape that covers the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer together, the toes are fully extended. Therefore, in this case, the "walking with the feet grasping the ground" that humans can originally have, which can efficiently transmit the force of the toes to the ground, can be particularly effective during sports such as walking, strolling, and running.

[0044] In the sock described in [9], when the toe part at the front end of the sock is formed in the shape of a foot bag that separately covers the thumb, index finger, middle finger, ring finger, and little finger of the wearer's foot, by freeing the big toe, the adaptability of the foot to fast-paced sports can be improved. In addition, for example, in sports such as table tennis and badminton, as well as in mountain climbing, etc., it is also useful in sports where the ground is uneven, such as skiing, where pressure is exerted on the big toe.

[0045] Especially in forward-charging sports such as rugby, sprinting, and long jumping, when an ordinary sock kicks on the ground, the little toe will protrude outward. In response, in the sock described in [9], when the toe part at the front end of the sock is formed in a four-fork shape that separately covers the thumb, index finger, middle finger, and ring finger (fourth toe) and little finger of the wearer's foot, the little finger and the ring finger are fixed, thereby enabling efficient transmission of longitudinal movement energy to the ground. Therefore, in this case, the adaptability to forward-charging sports such as rugby, sprinting, and long jumping can be particularly improved.

[0046] In the sock described in [9], when the toe part at the front end of the sock is formed in the shape of a five-finger shape that separately covers the thumb, index finger, middle finger, ring finger, and little finger of the wearer's foot, in the case where there are disadvantages such as stuffiness between multiple toes and ingrown toenails for people with hyperhidrosis prevention, it can protect each toe and does not hinder the mechanical conduction of ligaments during sports, and transmits force to the ground.

[0047]

[10] is the sock described in any one of [1] to [8], wherein The toe part at the front end of the sock is formed in a round head shape that covers the thumb, index finger, middle finger, ring finger, and little finger of the wearer's foot together, The anti-slip part further includes an anti-slip part for the round head shape, and the anti-slip part for the round head shape is formed in a single area including all areas corresponding to the belly parts of the thumb, index finger, middle finger, ring finger, and little finger of the wearer's foot on the outer side and / or inner side of the bottom surface of the sock.

[0048] According to the sock described in

[10] , through the anti-slip part for the round head shape, the effect brought by the toe part at the front end of the sock being formed in a round head shape can be improved.

[0049]

[11] is the sock described in any one of [1] to [8], wherein The toe part at the front end of the sock is formed in the shape of a foot bag that separately covers the thumb, index finger, middle finger, ring finger, and little finger of the wearer's foot, The anti-slip part further includes an anti-slip part for the sock form, and the anti-slip part for the sock form is formed in two regions, namely, the region corresponding to the belly part of the thumb of the foot of the sock wearer on the outer side and / or the inner side of the bottom surface of the sock, and a single region including all the regions corresponding to the belly parts of the index finger, middle finger, ring finger and little finger.

[0050] According to the sock described in

[11] , the anti-slip part for the sock form can improve the effect brought by forming the toe part at the front end of the sock into the sock form.

[0051]

[12] is the sock described in any one of [1] to [8], wherein The toe part at the front end of the sock is formed into a four-fork form that separately covers the thumb, index finger, middle finger, and ring finger and little finger of the foot of the sock wearer. The anti-slip part further includes an anti-slip part for the four-fork form, and the anti-slip part for the four-fork form is formed in four regions, namely, the region corresponding to the belly part of the thumb of the foot of the sock wearer on the outer side and / or the inner side of the bottom surface of the sock, the region corresponding to the belly part of the index finger, the region corresponding to the belly part of the middle finger, and a single region including all the regions corresponding to the belly parts of the ring finger and little finger.

[0052] According to the sock described in

[12] , the anti-slip part for the four-fork form can improve the effect brought by forming the toe part at the front end of the sock into the four-fork form.

[0053]

[13] is the sock described in any one of [1] to [8], wherein The toe part at the front end of the sock is formed into a five-finger form that separately covers the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer. The anti-slip part further includes an anti-slip part for the five-finger form, and the anti-slip part for the five-finger form is formed in five regions, namely, the region corresponding to the belly part of the thumb of the foot of the sock wearer on the outer side and / or the inner side of the bottom surface of the sock, the region corresponding to the belly part of the index finger, the region corresponding to the belly part of the middle finger, the region corresponding to the belly part of the ring finger, and the region corresponding to the belly part of the little finger.

[0054] According to the sock described in

[13] , the anti-slip part for the five-finger form can improve the effect brought by forming the toe part at the front end of the sock into the five-finger form.

[0055] [Details of the embodiments of the present invention] Next, specific examples of the socks related to the embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited by the following examples. For example, hereinafter, for the sake of simplicity of description, etc., in the examples, socks having all the above configurations are used for description, but the above respective configurations can be arbitrarily combined.

[0056] (Embodiment 1) Use Figures 1 to 17 to describe the socks of Embodiment 1. In addition, in Embodiment 1, the toe side of the sock 1 is described as the front of the sock, the heel side of the sock 1 is described as the rear of the sock, the width direction of the foot of the sock 1 is described as the sock width direction, the dorsal side of the sock 1 is described as the upper side of the sock, the sole side of the sock 1 is described as the lower side of the sock, the arch side of the sock is described as the inner side of the sock, and the opposite side of the inner side of the sock is described as the outer side of the sock. In addition, in the following examples, the sock 1 applicable to the right foot of the sock wearer is used as an example for description. For the configuration of the sock 1 applicable to the left foot of the sock wearer, the configuration of the sock 1 for the right foot may be set to be left-right reversed. In addition, for the sake of easy understanding, etc., Figure 1 and Figure 2 are diagrams obtained by simplifying and projecting the plantar aponeurosis f1, the superficial transverse metatarsal ligament f8, and the sesamoid bone f10 of the right foot of the sock wearer on the sock bottom surface 11. In addition, Figures 1 to 3 For Figures 4 to 10 is shown in an enlarged manner. In addition, Figures 11 to 17 is a diagram schematically showing various ligaments, bones, muscles, etc. in a human right foot, and these can be appropriately considered.

[0057] As Figures 1 to 10 shown, the sock 1 of Embodiment 1 has anti-slip portions 12 on both the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11 that comes into contact with the sole of the sock wearer when the sock is worn.

[0058] Such anti-slip portions 12 can be formed by performing anti-slip processing on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11 with an anti-slip material composed of a known polymer material (rubber, elastomer, resin, etc., more specifically, silicone rubber, silicone elastomer, etc.) for known socks, gloves, etc. Here, as the anti-slip material, for example, silicone rubber can be used, but there is no particular limitation as long as it is an anti-slip material that can exhibit an anti-slip function. In addition, the inner side surface 11i of the sock bottom surface 11 is the surface on the opposite side of the outer side surface 11o of the sock bottom surface 11. In other words, the outer side surface 11o of the sock bottom surface 11 can also be the surface on the opposite side of the inner side surface 11i of the sock bottom surface 11. In addition, the inner side surface 11i of the sock bottom surface 11 can also be the surface that comes into contact with the skin of the sole of the sock wearer.

[0059] AsFigure 1 and Figure 2 As shown in Figure 11 , the anti-slip part 12 includes a first anti-slip part 121 which is formed on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11 along the direction of the plantar aponeurosis f1 in the sole of the foot as shown in (a) of Figure 11 . Figure 11 Specifically, the first anti-slip part 121 can be constituted by applying anti-slip processing on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11 along the direction of the plantar aponeurosis f1. In addition, along the direction of the plantar aponeurosis f1 means overlapping with the plantar aponeurosis f1 projected on the sock bottom surface 11, and it does not require strictly following the shape of the plantar aponeurosis f1 projected on the sock bottom surface 11. The same explanation is made for "along the direction" in the following description. More specifically, the first anti-slip part 121 can be configured to include a plurality of square anti-slip parts 121a for the plantar aponeurosis in a polygonal shape (here a quadrilateral) and a plurality of circular anti-slip parts 121b for the plantar aponeurosis in a circular shape. The square anti-slip part 121a for the plantar aponeurosis is formed in a square shape, so it has the advantage of easily ensuring the overlapping area with the plantar aponeurosis f1. In addition, the circular anti-slip part 121b for the plantar aponeurosis is formed in a circular shape (dot-like), so it has the advantage of easily suppressing the position deviation of the sock 1 during the movement of the sock wearer.

[0060] If the first anti-slip part 121 includes an anti-slip part configured to overlap with the plantar aponeurosis f1, it may include an anti-slip part that extends beyond the plantar aponeurosis f1. For example, in Figure 1 and Figure 2 , a square anti-slip part 121a for the plantar aponeurosis configured to overlap with the plantar aponeurosis f1 on the front side of the sock and not extending beyond the plantar aponeurosis f1, a square anti-slip part 121a for the plantar aponeurosis configured to overlap with the plantar aponeurosis f1 and extending beyond the plantar aponeurosis f1, etc. are illustrated.

[0061] In addition, in Figure 1 and Figure 2 , a circular anti-slip part 121b for the plantar aponeurosis configured to overlap with the plantar aponeurosis f1 on the rear side of the sock and not extending beyond the plantar aponeurosis f1 is illustrated. In Figure 1 and Figure 2 , in addition to the circular anti-slip part 121b for the plantar aponeurosis, in the heel side area of the sock 1, from the viewpoint of improving the anti-slip effect, etc., a plurality of circular anti-slip parts 121c outside the plantar aponeurosis that do not overlap with the plantar aponeurosis f1 are shown to be arranged in a manner surrounding the outer periphery of the plurality of circular anti-slip parts 121b for the plantar aponeurosis. In addition, the circular anti-slip part 121c outside the plantar aponeurosis can be arranged not only on the sock bottom surface 11, but also, for example, extended upward to the sock in the rear direction of the heel part of the sock 1. Figure 1 and Figure 2

[0062] Figure 1 In addition, in Figure 1 and Figure 2 Figure 1 Figure 1 and Figure 2 Figure 2

[0063] As Figure 1 and Figure 2 shown, the anti-slip part 12 may further include a second anti-slip part 122, and the second anti-slip part 122 is formed on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11 along the direction of the plantar long ligament f2 in the sole of the foot as shown in (b) in Figure 11 and (a) in Figure 12 .

[0064] Specifically, the second anti-slip part 122 can be formed by applying anti-slip processing to the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11 along the direction of the plantar long ligament f2. More specifically, in order to overlap with the area corresponding to the plantar long ligament f2, the second anti-slip part 122 can be formed into a shape similar to the outer shape of the plantar long ligament f2. In Embodiment 1, the second anti-slip part 122 is composed of a single anti-slip part.

[0065] As Figure 12 shown, the abductor hallucis brevis f3, the adductor hallucis (oblique head) f4, the flexor digiti minimi brevis f5, the opponens digiti minimi f6, and the peroneus brevis f7 are connected (attached) to the plantar long ligament f2, and these are closely related to the constitution and stability of the longitudinal arch (plantar arch cover) of the foot. From the viewpoints of improving the effect of lifting the arch of the foot brought by the second anti-slip part 122 with a thickness and improving the stability of the longitudinal arch of the foot, etc., the thickness of the second anti-slip part 122 is preferably configured to be thicker than the thickness of the first anti-slip part 121. However, the thickness of the second anti-slip part 122 can also be equal to the thickness of the first anti-slip part 121. In this case, the thickness of the part of the sock bottom surface 11 where the second anti-slip part 122 is formed is preferably formed to be thicker than the thickness of the periphery of this part of the sock bottom surface 11. According to this constitution, in addition to the thickness caused by the formation of the second anti-slip part 122, the effect of increasing the thickness of the part of the sock bottom surface 11 where the second anti-slip part 122 is formed is also utilized. In the case where the thickness of the second anti-slip part 122 is set to be equal to the thickness of the first anti-slip part 121, the effect of lifting the arch of the foot can also be enhanced, and the stability of the longitudinal arch of the foot can be improved. In this case, further, in the case where the thickness of the second anti-slip part 122 is formed to be thicker than the thickness of the first anti-slip part 121, the above effects can be further enhanced.

[0066] In addition, when the plantar aponeurosis f1 and the plantar long ligament f2 are projected onto the sock bottom surface 11, the two overlap. In the sock 1 of Embodiment 1, for the part where the second anti-slip part 122 should be formed along the direction of the plantar long ligament f2 in the area corresponding to the plantar aponeurosis f1 on the sock bottom surface 11, the first anti-slip part 121 is not formed, and the second anti-slip part 122 is preferentially formed.

[0067] As Figure 1 andFigure 2 As shown, the anti-slip portion 12 can further include a third anti-slip portion 123, and this third anti-slip portion 123 is formed on the outer side surface 11o and the inner side surface 11i of the bottom surface 11 of the sock along Figure 13 the direction of the superficial transverse metatarsal ligament f8 in the sole of the foot as shown.

[0068] Specifically, the third anti-slip portion 123 can be constituted by applying anti-slip processing on the outer side surface 11o and the inner side surface 11i of the bottom surface 11 of the sock along the direction of the superficial transverse metatarsal ligament f8. In addition, as Figure 13 shown, the superficial transverse metatarsal ligament f8 is connected to the adductor hallucis (transverse head) f9, and these are closely related to the constitution and stability of the transverse arch of the foot. More specifically, the third anti-slip portion 123 can be configured to include a plurality of circular anti-slip portions 123b for the superficial transverse metatarsal ligament in a circular shape. There are the following advantages: In the third anti-slip portion 123, when the direction and angle of the circular anti-slip portion 123b for the superficial transverse metatarsal ligament change in the direction of pressing the third anti-slip portion 123 through the sole of the foot, the reaction force acts to easily lift the superficial transverse metatarsal ligament f8 and maintain the transverse arch.

[0069] The circular anti-slip portion 123b for the superficial transverse metatarsal ligament can be configured such that the outer diameter gradually or stepwise decreases from the inner side of the sock 1 toward the outer side of the sock 1. According to this configuration, there is an advantage of being easily along the direction of the superficial transverse metatarsal ligament f8. In Figure 1 and Figure 2 specifically, an example is shown in which, taking the portion corresponding to each root of the middle finger of the foot in the bottom surface 11 of the sock as a boundary, the outer side of the sock 1 is formed to have a smaller outer diameter than the inner side of the sock 1. In other words, in Figure 1 and Figure 2 the circular anti-slip portion 123b for the superficial transverse metatarsal ligament is configured such that the outer diameter decreases stepwise (here, at the first step) from the inner side of the sock 1 toward the outer side of the sock 1. In Figure 1 and Figure 2 an example is shown in which, compared with the above boundary, the outer diameter of the circular anti-slip portion 123b for the superficial transverse metatarsal ligament disposed on the inner side of the sock 1 is formed to be equal to the outer diameter of the circular anti-slip portion 121b for the plantar aponeurosis in the first anti-slip portion 121, but it is not limited thereto.

[0070] In addition, when the plantar aponeurosis f1 and the superficial transverse metatarsal ligament f8 are projected onto the bottom surface 11 of the sock, the two overlap. In the sock 1 of Embodiment 1, for the portion in the region of the bottom surface 11 of the sock corresponding to the plantar aponeurosis f1 and along the direction of the superficial transverse metatarsal ligament f8 where the third anti-slip portion 123 should be formed, the first anti-slip portion 121 is not formed, and the third anti-slip portion 123 is preferentially formed.

[0071] As Figure 1 and Figure 2As shown, the anti-slip portion 12 can further include a fourth anti-slip portion 124, which sandwiches the sesamoid bone f10 in the big toe of the sock wearer from the front-back direction of the sock (refer to Figure 14 in (a) and Figure 15 in (b)), and is formed on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11 in a manner that sandwiches the sesamoid bone position P corresponding thereto.

[0072] Specifically, the fourth anti-slip portion 124 can be composed of a pair of anti-slip portions 124o for the outer sesamoid bone that sandwich the outer sesamoid bone position Po corresponding to the outer sesamoid bone f10o in the big toe shown in (a) of Figure 14 from the front-back direction of the sock, and a pair of anti-slip portions 124i for the inner sesamoid bone that sandwich the inner sesamoid bone position Pi corresponding to the inner sesamoid bone f10i in the big toe shown in (a) of Figure 15 from the front-back direction of the sock. The anti-slip portion 124o for the outer sesamoid bone can be arranged to overlap with the regions corresponding to the lateral phalangeal sesamoid ligament f11o1 and the lateral metatarsal sesamoid ligament f11o2 shown in (b) and Figure 14 in (c) of Figure 14 on the sock bottom surface 11. Similarly, the anti-slip portion 124i for the inner sesamoid bone can be arranged to overlap with the regions corresponding to the medial phalangeal sesamoid ligament f11i1 and the medial metatarsal sesamoid ligament f11i2 shown in (b) and Figure 15 in (c) of Figure 15 on the sock bottom surface 11.

[0073] In addition, when the plantar aponeurosis f1, the lateral phalangeal sesamoid ligament f11o1, the lateral metatarsal sesamoid ligament f11o2, the medial phalangeal sesamoid ligament f11i1, and the medial metatarsal sesamoid ligament f11i2 are projected onto the sock bottom surface 11, they overlap. In the sock 1 of Embodiment 1, in the part of the fourth anti-slip portion 124 that should be formed to sandwich the sesamoid bone position P in the region corresponding to the plantar aponeurosis f1 on the sock bottom surface 11 from the front-back direction of the sock, the first anti-slip portion 121 is not formed, and the fourth anti-slip portion 124 is preferentially formed.

[0074] As Figure 1 and Figure 2 shown, in the regions of the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11 corresponding to the plantar arch cover (arch) of the sole, the sock 1 of Embodiment 1 can be configured to have a non-slip non-formation region 13 where the anti-slip portion 12 is not formed.

[0075] The sock 1 can have the non-slip non-formation region 13 in a part of the region of the sock bottom surface 11 corresponding to the plantar arch cover, or can have the non-slip non-formation region 13 in the whole region of the sock bottom surface 11 corresponding to the plantar arch cover.

[0076] AsFigures 4 to 10 As shown in, the area of the sock 1 of Embodiment 1 corresponding to the inferior extensor retinaculum f14 and the inferior peroneal retinaculum f15 of the foot of the sock wearer can be configured to have a first braided band portion 141 formed by a braided band. In addition, being formed by a braided band means that the sock fabric is woven to form and can play the role of a braided band. The same applies hereinafter. The first braided band portion 141 can be formed only on the instep portion of the sock, or can be formed not only on the instep portion of the sock, but also such that its end portion is disposed on the bottom surface 11 of the sock. Figure 17 As shown in, the area of the sock 1 of Embodiment 1 corresponding to the inferior extensor retinaculum f14 and the inferior peroneal retinaculum f15 of the foot of the sock wearer can be configured to have a first braided band portion 141 formed by a braided band. In addition, being formed by a braided band means that the sock fabric is woven to form and can play the role of a braided band. The same applies hereinafter. The first braided band portion 141 can be formed only on the instep portion of the sock, or can be formed not only on the instep portion of the sock, but also such that its end portion is disposed on the bottom surface 11 of the sock.

[0077] As Figures 4 to 10 shown in, the sock 1 of Embodiment 1 can also be configured to have a second braided band portion 142 formed by a braided band and extending from the first braided band portion 141. Specifically, the second braided band portion 142 is formed in a region corresponding to the following path: from Figure 17 the inferior extensor retinaculum f14 of the foot of the sock wearer shown in, passing above the lateral malleolus f16o of the foot of the sock wearer, surrounding the lateral head of the Achilles tendon f17 of the sock wearer, and returning to the inferior extensor retinaculum f14 after passing above the medial malleolus f16i of the foot of the sock wearer. In addition, Figure 7 the star mark Si in Figure 8 is a mark showing the position corresponding to the medial malleolus f16i of the foot of the sock wearer,

[0078] As Figures 4 to 10 shown in, the sock 1 of Embodiment 1 can be configured as follows: a third braided band portion 143 formed by a braided band in a region surrounding the corresponding area in the sock width direction of the sock 1, that is, from the dorsal side of the foot of the sock 1 to the inner side of the sock 1, and then from the inner side of the sock 1 to the dorsal side of the foot of the sock 1 in a loop. According to this configuration, there is an advantage that the braiding effect brought by the first braided band portion 141 can be improved.

[0079] In the sock 1 of Embodiment 1, as Figure 1 and Figure 2 shown in, the toe portion 15 at the front end of the sock 1 is formed to cover the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer together. Hereinafter, this form will be referred to as a round toe form. The toe portion 15 at the front end of the sock 1 is not limited to the round toe form. For example, as shown in (a) in Figure 3 , it can be formed to separately cover the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer. Hereinafter, this form will be referred to as a foot bag form. For example, as Figure 3As shown in (b) thereof, the toe portion 15 at the front end of the sock 1 can be formed to separately cover the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer. Hereinafter, this form will be referred to as a four-fork form. For example, as shown in Figure 3 in (c) thereof, the toe portion 15 at the front end of the sock 1 can be formed to separately cover the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer. Hereinafter, this form will be referred to as a five-finger form.

[0080] In Figure 1 and Figure 2 in the case of the round toe form shown, from the viewpoint of enhancing the effects brought by the above round toe form, the anti-slip portion 12 preferably includes an anti-slip portion 125 for the round toe form, and the anti-slip portion 125 for the round toe form is formed as a single region including all of the regions corresponding to the belly parts of the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11.

[0081] In addition, in Figure 3 in the case of the sock form shown in (a) thereof, from the viewpoint of enhancing the effects brought by the above sock form, the anti-slip portion 12 preferably has an anti-slip portion 125a for the sock form, and the anti-slip portion 125a for the sock form is formed in two regions, namely, the region corresponding to the belly part of the thumb of the foot of the sock wearer and the single region including all of the regions corresponding to the belly parts of the index finger, middle finger, ring finger, and little finger on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11, respectively.

[0082] In addition, in Figure 3 in the case of the four-fork form shown in (b) thereof, from the viewpoint of enhancing the effects brought by the above four-fork form, the anti-slip portion 12 preferably has an anti-slip portion 125b for the four-fork form, and the anti-slip portion 125b for the four-fork form is formed in four regions, namely, the region corresponding to the belly part of the thumb of the foot of the sock wearer, the region corresponding to the belly part of the index finger, the region corresponding to the belly part of the middle finger, and the single region including all of the regions corresponding to the belly parts of the ring finger and the little finger on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11, respectively.

[0083] In addition, in Figure 3In the case of the five-finger shape shown in (c) above, from the viewpoint of enhancing the effect brought about by the above five-finger shape, the anti-slip part 12 preferably has an anti-slip part 125c for the five-finger shape, and the anti-slip part 125c for the five-finger shape is formed in the regions corresponding to the belly parts of the thumb, index finger, middle finger, ring finger, and little finger of the foot of the sock wearer on the outer side surface 11o and the inner side surface 11i of the bottom surface 11 of the sock, respectively.

[0084] In addition, the sock 1 related to the above design and specifications can be manufactured by appropriately combining known manufacturing methods.

[0085] (Embodiment 2) The sock of Embodiment 2 will be described. In addition, among the reference numerals used in Embodiment 2 and below, the reference numerals that are the same as those used in the existing embodiments represent the same constituent elements and the like as those in the existing embodiments, unless otherwise specified.

[0086] The sock 1 of Embodiment 2 is different from the sock 1 of Embodiment 1 in that the outer side surface 11o of the bottom surface 11 of the sock that comes into contact with the sole of the sock wearer when the sock wearer is wearing the sock has an anti-slip part 12, and the inner side surface 11i of the bottom surface 11 of the sock does not have an anti-slip part 12. That is, the sock 1 of the above Embodiment 1 is an example in which the anti-slip part 12 is provided on both the outer side surface 11o and the inner side surface 11i of the bottom surface 11 of the sock, while the sock 1 of Embodiment 2 is an example in which the anti-slip part 12 is provided only on the outer side surface 11o of the bottom surface 11 of the sock. Other configurations are the same as those of Embodiment 1.

[0087] Compared with the sock 1 of Embodiment 1, the sock 1 of Embodiment 2 has a smaller effect, but can efficiently transmit the force of the ligaments related to the movement of the foot of the sock wearer during movement to the ground. In addition, since the sock 1 of Embodiment 2 does not have an anti-slip part 12 on the inner side surface 11i of the bottom surface 11 of the sock, correspondingly, the sock manufacturability is improved compared with the sock 1 of Embodiment 1. Therefore, the sock 1 of Embodiment 2 can be made into a sock 1 with high productivity and lower cost. In addition, the sock 1 of Embodiment 2 has an anti-slip part 12 only on the outer side surface 11o of the bottom surface 11 of the sock, and has an excellent advantage in the anti-slip processability of the anti-slip part 12 compared with the sock 1 of Embodiment 3 described later. Other effects are the same as those of Embodiment 1.

[0088] (Embodiment 3) The sock of Embodiment 3 will be described.

[0089] From the perspective that the inner side surface 11i of the sock bottom surface 11, which comes into contact with the sole of the sock wearer when the sock 1 of Embodiment 3 is worn, has the anti-slip portion 12 and the outer side surface 11o of the sock bottom surface 11 does not have the anti-slip portion 12, it is different from the sock 1 of Embodiment 1. That is, the sock 1 of the above-mentioned Embodiment 1 is an example in which the anti-slip portion 12 is provided on both the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11. In contrast, the sock 1 of Embodiment 3 is an example in which the above-mentioned anti-slip portion 12 is provided only on the inner side surface 11i of the sock bottom surface 11. Other configurations are the same as those of Embodiment 1.

[0090] Compared with the sock 1 of Embodiment 1, the sock 1 of Embodiment 3 has a smaller effect, but can efficiently transmit the force of the ligament related to the movement of the foot of the sock wearer during exercise to the ground. In addition, since the sock 1 of Embodiment 3 does not have the anti-slip portion 12 on the outer side surface 11o of the sock bottom surface 11, the appearance of the outer side surface 11o of the sock bottom surface 11 can be made the same as that of a general sock. Other effects are the same as those of Embodiment 1.

[0091] The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist thereof. In addition, the respective configurations shown in the above-described embodiments can be arbitrarily combined.
