Implementation

[0011] [Description of Embodiments of the Present Disclosure] First, the implementation aspects of the present disclosure are described. [1] A pair of socks having an anti-slip portion on the outer side of the bottom surface of the socks that the sole of the wearer's foot contacts when the wearer wears the socks and / or the inner side surface of the surface opposite to the outer side surface of the bottom surface of the socks, The aforementioned anti-slip portion comprises: The first anti-slip portion is formed on the outer side and / or inner side of the bottom surface of the sock along the direction of the plantar fascia in the sole of the foot.

[0012] As shown in FIG. 11( a ), the plantar fascia f1 in the sole of the foot is a ligament extending to the entire sole of the foot, and has the function of balancing the movement of the foot. The anti-slip portion in the socks described in [1] above further includes: a first anti-slip portion formed on the outer side and / or inner side of the bottom surface of the sock along the direction of the plantar fascia in the sole of the foot. Therefore, with the socks described in [1] above, the force of the ligament related to the movement of the foot of the wearer during exercise can be efficiently transmitted to the ground.

[0013] [2] The socks as described in [1], wherein: The aforementioned anti-slip portion further comprises: A second anti-slip portion is formed on the outer side and / or inner side of the bottom surface of the sock along the direction of the long plantar ligament in the sole of the foot.

[0014] As shown in FIG. 11( b ) and FIG. 12( a ), the long plantar ligament f2 in the sole of the foot is connected (attached) to the flexor hallucis brevis f3, adductor hallucis (oblique head) f4, flexor digiti minimi brevis f5, opponens digiti minimi f6, and peroneus brevis f7, which are important for transmitting kinetic energy backward when the sole of the foot contacts the ground during walking or running (see FIG. 12( b ) to ( f )). These muscles are strongly related to the structure and stability of the longitudinal arch (arch of the foot). The anti-slip portion in the sock described in the above [2] further includes: a second anti-slip portion formed on the outer side and / or inner side of the bottom surface of the sock along the direction of the long plantar ligament in the sole of the foot. Therefore, the sock described in the above [2] can produce an effect of lifting the sole of the foot due to the increase in thickness of the second anti-slip portion formed in a manner overlapping the area corresponding to the long plantar ligament in the outer side and / or inner side of the bottom surface of the sock, thereby improving the stability of the longitudinal arch of the foot. Furthermore, the socks described in [2] can improve the movement of the aforementioned various muscles by improving the stability of the longitudinal arch. Therefore, with the socks described in [2], the force of the ligaments related to the movement of the foot of the wearer during exercise can be efficiently transmitted to the ground.

[0015] [3] The socks as 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 surroundings of the portion of the bottom surface of the sock.

[0016] In the socks described in [3], when the thickness of the second anti-slip portion is formed to be thicker than the thickness of the first anti-slip portion, the above-mentioned effect of lifting the sole of the foot due to the second anti-slip portion having a thickness is improved, and the stability of the longitudinal arch of the foot can be further improved. On the other hand, in the socks described in [3], when the thickness of the portion of the bottom surface of the sock formed with the second anti-slip portion is formed to be thicker than the thickness of the surrounding portion of the bottom surface of the sock, even if the thickness of the second anti-slip portion is formed to be the same as the thickness of the first anti-slip portion, the portion of the bottom surface of the sock formed with the second anti-slip portion has a thickness, and the above-mentioned effect of lifting the sole of the foot due to the second anti-slip portion is improved, and the stability of the longitudinal arch of the foot can be further improved. Therefore, with the socks described in [3], the effect of the socks described in [2] can be made more certain.

[0017] [4] The socks as described in any one of [1] to [3], wherein: The aforementioned anti-slip portion further comprises: The third anti-slip portion is formed on the outer side and / or the inner side of the bottom surface of the sock along the direction of the superficial metatarsal transverse ligament in the sole of the foot.

[0018] As shown in FIG. 13 , the superficial metatarsal transverse ligament f8 in the sole of the foot is connected to the adductor hallucis (lateral head) f9, and has the function of maintaining the transverse arch of the foot, which is indispensable for the movement from the big toe to the little toe of the foot. The plurality of anti-slip parts in the socks described in the above [4] also include a third anti-slip part formed on the outer side and / or the inner side of the bottom surface of the sock along the direction of the superficial metatarsal transverse ligament in the sole of the foot. Therefore, the socks described in the above [4] generate a force that presses the superficial metatarsal transverse ligament to the dorsal side of the foot by the reaction force caused by the third anti-slip part, and as a result, the transverse arch of the foot is maintained, and all toes are easily extended, and the toes can firmly grip the ground. Therefore, with the socks described in the above [4], the force of the ligament related to the movement of the foot of the wearer during exercise can be efficiently transmitted to the ground.

[0019] [5] The socks as described in any one of [1] to [4], wherein: The aforementioned anti-slip portion further comprises: The fourth anti-slip portion is formed on the outer side and / or inner side of the bottom surface of the sock so as to sandwich the sesamoid bone position corresponding to the sesamoid bone in the thumb of the sock wearer from the front-back direction of the sock.

[0020] As shown in FIG. 14( a) and FIG. 15( a), the sesamoid bone f10 in the thumb has the function of acting as a pulley of the tendon, making the movement of the joint or ligament smooth. The plurality of anti-slip portions in the socks described in the above [5] further include a fourth anti-slip portion formed on the outer side and / or inner side of the bottom surface of the sock in such a manner as to sandwich the sesamoid bone position corresponding to the sesamoid bone in the thumb of the sock wearer from the front-back direction of the sock. Therefore, with the socks described in the above [5], the sesamoid bone in the thumb is sandwiched from the front-back direction of the sock by the fourth anti-slip portion and becomes stable, and the function of the sesamoid bone is improved. Therefore, with the socks described in the above [5], the force of the ligaments related to the movement of the foot of the sock wearer during exercise can be efficiently transmitted to the ground. In addition, with the socks described in the above [5], the effect of preventing sesamoiditis and the like can be expected.

[0021] [6] The socks as described in any one of [1] to [5], wherein: The area corresponding to the arch of the sole of the foot on the outer side and / or the inner side of the bottom surface of the sock has an anti-slip non-formed area where the anti-slip portion is not formed.

[0022] The arch of the sole of the foot, as shown in FIG. 16 , is where the tendons (flexor digitorum longus f12 and flexor hallucis longus f13) cross. If this place is compressed, the movement of the foot will be restricted. The socks described in [6] above have a non-slip non-formed area where the non-slip part is not formed in the area corresponding to the arch of the sole of the foot on the outer side and / or inner side of the bottom surface of the sock. Therefore, the socks described in [6] above, due to the presence of the non-slip non-formed area, the place where the tendons cross is difficult to be compressed by the non-slip part. Therefore, with the socks described in [6] above, the force of the ligaments related to the movement of the foot of the wearer during exercise can be efficiently transmitted to the ground.

[0023] [7] The socks as described in any one of [1] to [6], wherein: The first braided portion is formed by braiding the area corresponding to the lower extensor support band and the lower peroneal support band of the foot of the wearer of the socks.

[0024] As shown in FIG. 17 , the lower extensor support band f14 and the lower peroneal support band f15 of the foot have the function of suspending the longitudinal arch of the foot from above. The socks described in [7] above have a first braided portion formed by braiding in the area corresponding to the lower extensor support band and the lower peroneal support band of the foot of the sock wearer. Therefore, with the socks described in [7] above, the lower extensor support band and the lower peroneal support band of the foot can be protected by the first braided portion, thereby improving the stability of the longitudinal arch of the foot. Therefore, with the socks described in [7] above, the force of the ligaments related to the movement of the foot of the sock wearer during exercise can be efficiently transmitted to the ground.

[0025] [8] The socks as described in [7], wherein: a second braided portion extending from the first braided portion and formed by braiding, The second braided portion is formed at: Corresponding to: the area of ​​the path of the lower extensor support band of the foot of the sock wearer, passing above the lateral ankle of the foot of the sock wearer, around the lateral side of the head of the Achilles tendon of the sock wearer, and returning to the lower extensor support band through above the medial ankle of the foot of the sock wearer.

[0026] When a human foot joint is sprained, it is usually injured by inversion. The socks described in [8] above have the second tape portion in addition to the first tape portion. Therefore, with the socks described in [8] above, since the formation of the longitudinal arch of the foot caused by the first tape portion is promoted, inversion of the foot joint is easily suppressed. In addition, the second tape portion is constructed to avoid the Achilles tendon attachment portion that moves more during the exercise of the wearer of the socks and slightly move the end point to the head side, so that the movement of the Achilles tendon itself is unlikely to be hindered.

[0027] [9] The socks as described in any one of [1] to [8], wherein: The toe portion at the front end of the sock is formed as follows: The front round shape that covers the thumb, index finger, middle finger, ring finger and little finger of the wearer of the socks, or A foot cover type that covers the thumb, index finger, middle finger, ring finger and little finger of the wearer's foot separately, or A four-pronged pattern that covers the thumb, index finger, middle finger, ring finger, and little finger of the wearer's foot, or The five-finger shape of the wearer's foot, including the thumb, index finger, middle finger, ring finger, and little finger, is separately covered.

[0028] In the socks described in [9], the toe portion at the front end of the socks is formed into a front round shape that covers the thumb, index finger, middle finger, ring finger and little finger of the wearer's foot, so that the toes can be stretched out reliably. Therefore, in this case, since the power of the toes that humans originally have to "grip the ground and walk" can be efficiently transmitted to the ground, it can be particularly effective when walking, strolling, running, etc.

[0029] In the socks described in [9], the toe portion at the front end of the sock is formed into a foot cover type that covers the big toe, index finger, middle finger, ring finger and little finger of the wearer's foot separately, so that the big toe is free, and the adaptability of the foot to fast movements can be improved. In addition, for example, such as table tennis or badminton, and in the case of uneven ground such as mountain climbing, it is also useful for sports that apply pressure to the big toe, such as skiing.

[0030] In particular, in forward-moving sports such as rugby, sprinting, and long jump, if ordinary socks are used, the little toe will escape to the outside when the foot kicks the ground. In response to this, in the socks described in [9], the toe portion of the front end of the sock is formed into a four-pronged shape that covers the big toe, index finger, middle finger, ring finger (ring toe), and little finger of the wearer's foot. By fixing the little finger with the ring finger, the vertical movement energy can be efficiently transmitted to the ground. Therefore, in this case, the adaptability to forward-moving sports such as rugby, sprinting, and long jump can be improved.

[0031] In the socks described in [9], the toe portion at the front end of the socks is formed into a five-finger type that covers the big toe, index finger, middle finger, ring finger, and little finger of the wearer's foot. This can prevent stuffiness between the toes of people with hyperhidrosis or ingrown toenails, while protecting each finger without hindering the mechanical conduction of the ligaments during exercise to the ground.

[0032]

[10] The socks as described in any one of [1] to [8], wherein: The toe portion at the front end of the sock is formed as follows: The socks are formed into a front round shape in such a way as to cover the thumb, index finger, middle finger, ring finger and little finger of the wearer's foot. The aforementioned anti-slip portion further comprises: A circular anti-slip portion is formed in front of a single area on the outer side and / or inner side of the bottom surface of the sock, including all areas corresponding to the thumb, index finger, middle finger, ring finger and little finger webs of the wearer's foot.

[0033] With the socks described in

[10] , the effect of the toe portion at the front end of the socks being formed into a front round shape can be enhanced by using the anti-slip portion for the front round shape.

[0034]

[11] The socks as described in any one of [1] to [8], wherein: The toe portion at the front end of the sock is formed as follows: The foot cover type of the wearer of the above-mentioned socks separately covers the thumb, index finger, middle finger, ring finger and little finger of the foot. The aforementioned anti-slip portion further comprises: The anti-slip parts for the foot cover are respectively formed in two areas: an area corresponding to the web of the toe of the foot of the wearer of the socks, and a single area including all of the areas corresponding to the webs of the index finger, middle finger, ring finger and little finger.

[0035] With the socks described in

[11] , the effect of forming the toe portion of the front end of the socks into a foot cover shape can be improved by using the anti-slip portion of the foot cover shape.

[0036]

[12] The socks as described in any one of [1] to [8], wherein: The toe portion at the front end of the sock is formed as follows: The four-pronged pattern covers the thumb, index finger, middle finger, ring finger and little finger of the wearer's foot. The aforementioned anti-slip portion further comprises: The four-pronged anti-slip portion is respectively formed on the outer side and / or inner side of the bottom surface of the sock, which are the area corresponding to the pulp of the thumb of the wearer's foot, the area corresponding to the pulp of the index finger, the area corresponding to the pulp of the middle finger, and a single area including all the areas corresponding to the pulps of the ring finger and the little finger.

[0037] With the socks described in

[12] , the effect of the toe portion at the front end of the socks being formed into a four-pronged shape can be enhanced by using the four-pronged anti-slip portion.

[0038]

[13] The socks as described in any one of [1] to [8], wherein: The toe portion at the front end of the sock is formed as follows: The five fingers of the wearer's foot, including the thumb, index finger, middle finger, ring finger, and little finger, are covered separately. The aforementioned anti-slip portion further comprises: The five-finger anti-slip parts are respectively formed on the outer side and / or inner side of the bottom surface of the sock, which correspond to the area of ​​the thumb pad of the wearer's foot, the area of ​​the index finger pad, the area of ​​the middle finger pad, the area of ​​the ring finger pad, and the area of ​​the little finger pad.

[0039] With the socks described in

[13] , the effect of forming the toe portion of the front end of the socks into a five-finger shape can be enhanced by using the anti-slip portion for the five-finger shape.

[0040] [Detailed description of embodiments of the present disclosure] Next, a specific example of the socks according to the embodiment of the present disclosure is described in detail using drawings. The present disclosure is not limited to the following examples. For example, in the following, in order to simplify the description, a sock having all the above structures is described as an example, but the above structures can be arbitrarily combined.

[0041] (Implementation Method 1) The socks of the first embodiment are described using FIGS. 1 to 17. In the first embodiment, the toe side of the sock 1 is the front of the sock, the heel side of the sock 1 is the back of the sock, the width direction of the foot of the sock 1 is the width direction of the sock, the toe nail side of the sock 1 is the top of the sock, the sole side of the sock 1 is the bottom of the sock, the arch side of the sock is the inside of the sock, and the opposite side of the inside of the sock is the outside of the sock. In addition, in the following examples, the sock 1 applied to the right foot of the sock wearer is described as an example. For the structure of the sock 1 applied to the left foot of the sock wearer, the structure of the sock 1 for the right foot can be set to be opposite to the left and right. In addition, FIGS. 1 and 2 are simplified and projected onto the bottom surface 11 of the sock to facilitate understanding. In addition, Figures 1 to 3 are enlarged relative to Figures 4 to 10. In addition, Figures 11 to 17 are diagrams schematically showing various ligaments, bones, muscles, etc. in a person's right foot, and these can be appropriately referred to.

[0042] 1 to 10 , the sock 1 of the first embodiment has a non-slip portion 12 on both the outer side 11o of the sock bottom surface 11 which the sole of the sock wearer contacts when the sock wearer wears the sock and the inner side 11i of the sock bottom surface 11.

[0043] Such anti-slip portion 12 can be formed by performing anti-slip processing on the outer side 11o and inner side 11i of the sock bottom surface 11 using an anti-slip material made of a known polyester material (rubber, elastomer, resin, etc., more specifically, silicone, silicone elastomer, etc.) used in known socks or gloves. Here, as the anti-slip material, for example, silicone can be used, but it is not particularly limited as long as it can exert an anti-slip function. Moreover, the inner side 11i of the sock bottom surface 11 is the surface on the opposite side of the outer side 11o of the sock bottom surface 11. That is, the outer side 11o of the sock bottom surface 11 can also be said to be the surface on the opposite side of the inner side 11i of the sock bottom surface 11. In addition, the inner side 11i of the sock bottom surface 11 can also be said to be the surface that contacts the skin of the sole of the sock wearer.

[0044] As shown in Figures 1 and 2, the anti-slip portion 12 includes: a first anti-slip portion 121 formed on the outer side 11o and the inner side 11i of the bottom surface 11 of the sock along the direction of the plantar fascia f1 in the sole of the foot as shown in Figure 11 (a).

[0045] Specifically, the first anti-slip portion 121 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 fascia f1. Moreover, the so-called "along the direction of the plantar fascia f1" means overlapping with the plantar fascia f1 projected on the sock bottom surface 11, and does not strictly require the shape of the plantar fascia f1 projected on the sock bottom surface 11. The same interpretation applies to "along the direction" in the following description. More specifically, the first anti-slip portion 121 can be set to include a plurality of polygonal (here, quadrilateral) polygonal anti-slip portions 121a for plantar fascia and a plurality of circular anti-slip portions 121b for plantar fascia. The polygonal anti-slip portion 121a for plantar fascia has the advantage of being easily overlapped with the plantar fascia f1 because it is formed in a polygonal shape. In addition, the circular anti-slip portion 121b for the plantar fascia is formed in a circular shape (dot shape), which has the advantage of easily suppressing the displacement of the sock 1 when the wearer of the sock exercises.

[0046] The first anti-slip portion 121 may include an anti-slip portion arranged to overlap the plantar fascia f1 or an anti-slip portion protruding from the plantar fascia f1. For example, in FIG. 1 and FIG. 2, at a position closer to the front side of the sock than about halfway in the front-back direction of the sock, there are illustrated a polygonal anti-slip portion 121a for the plantar fascia arranged to overlap the plantar fascia f1 and not protrude from the plantar fascia f1; and a polygonal anti-slip portion 121a for the plantar fascia arranged to overlap the plantar fascia f1 and protrude from the plantar fascia f1.

[0047] In addition, in FIG. 1 and FIG. 2, a circular anti-slip portion 121b for plantar fascia is illustrated as being arranged to overlap with the plantar fascia f1 and not protrude from the plantar fascia f1 at a position closer to the rear side of the sock than about halfway in the front-back direction of the sock. In FIG. 1 and FIG. 2, in addition to the circular anti-slip portion 121b for plantar fascia, in the area on the heel side of the sock 1, from the viewpoint of improving the anti-slip effect, etc., an example is shown in which a plurality of plantar fascia outer circular anti-slip portions 121c that do not overlap with the plantar fascia f1 are arranged to surround the outer periphery of the plurality of plantar fascia outer circular anti-slip portions 121b. Moreover, the plantar fascia outer circular anti-slip portion 121c may be arranged, for example, to extend from the rear of the heel portion of the sock 1 to the upper side of the sock, in addition to the sock bottom surface 11.

[0048] As shown in Figures 1 and 2, the anti-slip portion 12 may also include: a second anti-slip portion 122 formed on the outer side 11o and the inner side 11i of the sock bottom 11 along the direction of the long plantar ligament f2 in the sole of the foot as shown in Figures 11(b) and 12(a).

[0049] The second anti-slip portion 122 can be formed by applying anti-slip processing to the outer side 11o and the inner side 11i of the sock bottom surface 11 along the direction of the long plantar ligament f2. More specifically, the second anti-slip portion 122 can be formed into a shape similar to the outer shape of the long plantar ligament f2 in a manner overlapping with the area corresponding to the long plantar ligament f2. In the first embodiment, the second anti-slip portion 122 is formed by a single anti-slip portion.

[0050] As shown in FIG. 12 , the long plantar ligament f2 is connected (attached) to the flexor hallucis brevis f3, the adductor hallucis (oblique head) f4, the flexor digiti minimi brevis f5, the palmar toe anteroposterior f6, and the peroneus brevis f7, which are strongly related to the structure and stability of the longitudinal arch (arch of the foot) of the foot. The thickness of the second anti-slip portion 122 is preferably thicker than the thickness of the first anti-slip portion 121 from the viewpoint of increasing the effect of lifting the sole of the foot by the second anti-slip portion 122 having a thickness and improving the stability of the longitudinal arch of the foot. Furthermore, the thickness of the second anti-slip portion 122 may be the same as the thickness of the first anti-slip portion 121. In this case, the thickness of the portion of the sock bottom surface 11 formed with the second anti-slip portion 122 is preferably thicker than the thickness of the surrounding portion of the sock bottom surface 11. According to this structure, in addition to the thickness due to the formation of the second anti-slip part 122, the thickness of the portion of the sock bottom surface 11 formed with the second anti-slip part 122 is increased, and even if the thickness of the second anti-slip part 122 is set to be the same as the thickness of the first anti-slip part 121, the effect of lifting the sole of the foot can be improved, and the stability of the longitudinal arch of the foot can be improved. In this case, if the thickness of the second anti-slip part 122 is further formed to be thicker than the thickness of the first anti-slip part 121, the above-mentioned effect can be further improved.

[0051] Furthermore, if the plantar fascia f1 and the long plantar ligament f2 are projected onto the sock bottom surface 11, the two overlap. In the sock 1 of the first embodiment, in the area of ​​the sock bottom surface 11 corresponding to the plantar fascia f1, the first anti-slip portion 121 is not formed in the portion where the second anti-slip portion 122 along the direction of the long plantar ligament f2 should be formed, and the second anti-slip portion 122 is formed preferentially.

[0052] As shown in Figures 1 and 2, the anti-slip portion 12 may further include: a third anti-slip portion 123 formed on the outer side 11o and the inner side 11i of the sock bottom surface 11 along the direction of the superficial metatarsal transverse ligament f8 in the sole of the foot as shown in Figure 13.

[0053] The third anti-slip portion 123 can be formed by applying anti-slip processing to the outer side 11o and the inner side 11i of the bottom surface 11 of the sock along the direction of the long plantar ligament f8. Moreover, as shown in FIG13, the superficial metatarsal transverse ligament f8 is connected to the adductor hallucis (lateral head) f9, which is strongly related to the structure and stability of the transverse arch of the foot. The third anti-slip portion 123 can be more specifically configured to include a plurality of circular anti-slip portions 123b for the superficial metatarsal transverse ligament. In the third anti-slip portion 123, the circular anti-slip portion 123b for the superficial metatarsal transverse ligament has the advantages of being able to easily lift the superficial metatarsal transverse ligament f8 and easily maintain the transverse arch even when the direction or angle of the third anti-slip portion 123 is changed by the sole of the foot.

[0054] The circular anti-slip portion 123b for the superficial metatarsal transverse ligament can be configured to have a structure in which the outer diameter is gradually or stagedly reduced from the inside of the sock 1 toward the outside of the sock 1. With this structure, there is an advantage that it is easy to follow the direction of the superficial metatarsal transverse ligament f8. In FIG. 1 and FIG. 2, specifically, an example is shown in which the outer diameter of the outside of the sock 1 is formed smaller than the inside of the sock 1, with the portion corresponding to the base of the middle toe of the foot in the bottom surface 11 of the sock as a border. That is, in FIG. 1 and FIG. 2, the circular anti-slip portion 123b for the superficial metatarsal transverse ligament is configured to have a structure in which the outer diameter is gradually (here, one stage) reduced from the inside of the sock 1 toward the outside of the sock 1. In Figures 1 and 2, it is shown that the outer diameter of the circular anti-slip portion 123b for the superficial metatarsal transverse ligament arranged on the inner side of the sock 1 closer to the above-mentioned border is formed to be the same as the outer diameter of the circular anti-slip portion 121b for the plantar fascia in the first anti-slip portion 121, but it is not limited to this.

[0055] Furthermore, if the plantar fascia f1 and the superficial metatarsal transverse ligament f8 are projected onto the sock bottom surface 11, the two overlap. In the sock 1 of the first embodiment, in the area of ​​the sock bottom surface 11 corresponding to the plantar fascia f1, the portion where the third anti-slip portion 123 along the direction of the superficial metatarsal transverse ligament f8 should be formed, the first anti-slip portion 121 is not formed, and the third anti-slip portion 123 is formed preferentially.

[0056] As shown in Figures 1 and 2, the anti-slip portion 12 may further include a fourth anti-slip portion 124 formed on the outer side surface 11o and the inner side surface 11i of the aforementioned sock bottom surface 11 in a manner that the sesamoid bone position P corresponding to the sesamoid bone f10 (refer to Figures 14(a) and 15(b)) in the thumb of the sock wearer is sandwiched from the front-to-back direction of the sock.

[0057] Specifically, the fourth anti-slip portion 124 may be composed of a pair of anti-slip portions 124o for the lateral sesamoid bones corresponding to the lateral sesamoid bone position Po of the lateral sesamoid bone f10o in the thumb as shown in FIG. 14(a) and a pair of anti-slip portions 124i for the medial sesamoid bones corresponding to the medial sesamoid bone position Pi of the medial sesamoid bone f10i in the thumb as shown in FIG. 15(a) . The anti-slip portions 124o for the lateral sesamoid bones may be arranged to overlap with the regions of the sock bottom surface 11 corresponding to the lateral phalangeal sesamoid bone ligament f11o1 and the lateral metatarsal sesamoid bone ligament f11o2 as shown in FIG. 14(b) and FIG. 14(c) . Similarly, the anti-slip portion 124i for the medial sesamoid bone can be configured to overlap with the area of ​​the sock bottom surface 11 corresponding to the medial phalangeal sesamoid bone ligament f11i1 and the medial metatarsal sesamoid bone ligament f11i2 as shown in Figures 15(b) and 15(c).

[0058] Furthermore, the plantar fascia f1 and 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, and these are repeated. In the sock 1 of the first embodiment, in the area corresponding to the plantar fascia f1 in the sock bottom surface 11, the fourth anti-slip portion 124 should be formed to sandwich the sesamoid position P from the front-back direction of the sock, but the first anti-slip portion 121 is not formed, and the fourth anti-slip portion 124 is formed first.

[0059] As shown in FIGS. 1 and 2 , the sock 1 of Embodiment 1 has a non-slip region 13 where the non-slip portion 12 is not formed, in the area corresponding to the arch (sole) of the sole of the foot on the lateral side 11o and / or medial side 11i of the sock bottom 11.

[0060] The sock 1 may have the non-slip area 13 partially in the area corresponding to the arch of the foot on the sock bottom surface 11, or may have the non-slip area 13 entirely in the area corresponding to the arch of the foot on the sock bottom surface 11.

[0061] As shown in FIGS. 4 to 10 , the sock 1 of the first embodiment may be configured to have a first braided portion 141 formed by braiding in the region corresponding to the lower extensor support band f14 and the lower peroneus support band f15 of the foot of the sock wearer as shown in FIG. 17 . Moreover, the term “formed by braiding” means that the sock fabric is knitted in a manner that can exert a taping effect. The same applies to the following. The first braided portion 141 may be formed only on the nail portion of the sock, or may be formed so that its end is arranged on the bottom surface 11 of the sock instead of the nail portion of the sock.

[0062] As shown in FIGS. 4 to 10 , the sock 1 of the first embodiment may be further provided with a second braided portion 142 extending from the first braided portion 141 and formed of braided tape. Specifically, the second braided portion 142 corresponds to a region of a path from the lower extensor support band f14 of the foot of the sock wearer as shown in FIG. 17 , passing above the lateral malleolus f16o of the foot of the sock wearer, surrounding the head lateral side of the Achilles tendon f17 of the sock wearer, and returning to the lower extensor support band f14 through above the medial malleolus f16i of the foot of the sock wearer. In addition, the asterisk Si in FIG. 7 is a mark indicating a position corresponding to the medial malleolus f16i of the foot of the sock wearer, and the asterisk So in FIG. 8 is a mark indicating a position corresponding to the lateral malleolus f16o of the foot of the sock wearer.

[0063] As shown in FIGS. 4 to 10 , the sock 1 of the first embodiment may be provided with a third braided tape portion 143, which is formed by braided tape and corresponds to the area around the sock 1 in the width direction of the sock, that is, the area from the toe nail side of the sock 1 to the inside of the sock 1 and then from the inside of the sock 1 to the toe nail side of the sock 1. With this structure, there is an advantage that the sticking effect of the first braided tape portion 141 can be enhanced.

[0064] The toe portion 15 of the sock 1 of the first embodiment is formed to cover the big toe, index finger, middle finger, ring finger and little finger of the wearer's foot as shown in Figures 1 and 2. Hereinafter, this shape is referred to as the front round shape. The toe portion 15 of the front end of the sock 1 is not limited to the front round shape, and may be formed to cover the big toe, index finger, middle finger, ring finger and little finger of the wearer's foot separately, for example, as shown in Figure 3 (a). Hereinafter, this shape is referred to as the foot cover shape. The toe portion 15 of the front end of the sock 1 may be formed to cover the big toe, index finger, middle finger, ring finger and little finger of the wearer's foot separately, for example, as shown in Figure 3 (b). Hereinafter, this shape is referred to as the four-pronged shape. The toe portion 15 at the front end of the sock 1 may be formed to cover the thumb, index finger, middle finger, ring finger, and little finger of the wearer's foot separately, as shown in FIG3(c). Hereinafter, this configuration is referred to as a five-finger configuration.

[0065] In the case of the front round shape illustrated in Figures 1 and 2, the anti-slip portion 12, from the perspective of improving the effect of the above-mentioned front round shape, can be formed on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11, including all the areas corresponding to the thumb, index finger, middle finger, ring finger and little finger webs of the sock wearer's foot. The front round shape anti-slip portion 125 is sufficient.

[0066] In addition, in the case of the foot cover type illustrated in FIG. 3( a), the anti-slip portion 12, from the viewpoint of improving the effect caused by the above-mentioned foot cover type, has two areas, namely, an area corresponding to the web of the big toe of the foot of the wearer of the sock formed on the outer side surface 11o and the inner side surface 11i of the bottom surface 11 of the sock; and a single area including all of the areas corresponding to the webs of the index finger, middle finger, ring finger and little finger. Anti-slip portion 125a for foot cover type

[0067] In addition, in the case of the four-pronged shape illustrated in FIG. 3( b), the anti-slip portion 12, from the perspective of improving the effect of the above-mentioned four-pronged shape, has a four-pronged anti-slip portion 125 b that is respectively formed on the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11, which correspond to the area of ​​the thumb web of the foot of the sock wearer, the area corresponding to the index finger web, the area corresponding to the middle finger web, and a single area including all of the areas corresponding to the ring finger and the little finger web.

[0068] In addition, in the case of the five-finger type illustrated in FIG. 3( c ), the anti-slip portion 12, from the viewpoint of improving the effect caused by the above-mentioned five-finger type, has: a five-finger type anti-slip portion 125 c formed in five areas of the outer side surface 11o and the inner side surface 11i of the sock bottom surface 11, which correspond to the area of ​​the thumb web portion of the sock wearer's foot, the area of ​​the index finger web portion, the area of ​​the middle finger web portion, the area of ​​the ring finger web portion, and the area of ​​the little finger web portion.

[0069] Moreover, the socks 1 of the above-mentioned design and specifications can be manufactured by appropriately combining known manufacturing methods.

[0070] (Implementation Method 2) The socks according to Embodiment 2 will be described. In addition, among the reference numerals used in Embodiment 2 and thereafter, those which are the same as those used in the previous embodiments represent the same components and the like as those in the previous embodiments unless otherwise indicated.

[0071] The socks 1 of the second embodiment differs from the socks 1 of the first embodiment in that the outer side surface 11o of the sock bottom surface 11 that the sole of the sock wearer contacts when the sock wearer wears the socks has the anti-slip portion 12, and the inner side surface 11i of the sock bottom surface 11 does not have the anti-slip portion 12. That is, the socks 1 of the first embodiment described above 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, whereas the socks 1 of the second embodiment is an example in which the anti-slip portion 12 is provided only on the outer side surface 11o of the sock bottom surface 11. The other structures are the same as those of the first embodiment.

[0072] Although the effect of the socks 1 of the second embodiment is smaller than that of the socks 1 of the first embodiment, the force of the ligaments related to the movement of the foot of the wearer of the socks during exercise can be transmitted to the ground with the best efficiency. In addition, since the socks 1 of the second embodiment do not have the anti-slip portion 12 on the inner side 11i of the sock bottom surface 11, the socks manufacturability can be improved compared with the socks 1 of the first embodiment. Therefore, the socks 1 of the second embodiment can be set as a sock 1 with high productivity and lower cost. In addition, since the socks 1 of the second embodiment have the anti-slip portion 12 only on the outer side 11o of the sock bottom surface 11, the anti-slip processability of the anti-slip portion 12 is excellent compared with the socks 1 of the third embodiment described later. The other effects are the same as those of the first embodiment.

[0073] (Implementation method 3) The socks according to the third embodiment will be described.

[0074] The socks 1 of the third embodiment are different from the socks 1 of the first embodiment in that the inner side 11i of the sock bottom surface 11 that the sole of the sock wearer contacts when the sock wearer wears the socks has the anti-slip portion 12, and the outer side 11o of the sock bottom surface 11 does not have the anti-slip portion 12. That is, the socks 1 of the first embodiment described above are examples of having the anti-slip portion 12 on both the outer side 11o and the inner side 11i of the sock bottom surface 11, whereas the socks 1 of the third embodiment are examples of having the anti-slip portion 12 only on the inner side 11i of the sock bottom surface 11. The other structures are the same as those of the first embodiment.

[0075] Although the socks 1 of the third embodiment have a smaller effect than the socks 1 of the first embodiment, the force of the ligaments related to the movement of the foot of the wearer during exercise can be efficiently transmitted to the ground. In addition, since the socks 1 of the third embodiment do 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 normal sock. The other effects are the same as those of the first embodiment.

[0076] The present disclosure is not limited to the above-mentioned embodiments, and various changes can be made as long as they do not deviate from the scope of the gist. In addition, the various structures shown in the above-mentioned embodiments can be combined arbitrarily.
