[0001] This application is based on Japanese Application No. 2023-167880, filed on September 28, 2023, the contents of which are incorporated herein by reference.

[0002] The present disclosure relates to socks.

[0003] 2. Description of the Related Art Conventionally, socks have been known that have anti-slip portions formed on the bottom surface of the sock to prevent the soles of the feet from slipping.

[0004] For example, the prior art Patent Document 1 discloses a sock having an anti-slip member on the outer surface of the sole, the sock having multiple first anti-slip members on the ball of the foot. In this sock, in order to improve the athletic ability of the wearer, the inner end of each first anti-slip member is closer to the heel than the outer end of the first anti-slip member, and the average angle on the sole of the foot between the line connecting the tip of the big toe and the tip of the heel and the longitudinal direction of each first anti-slip member, which faces outward toward the toes, is between 50 degrees and 100 degrees.

[0005] Japanese Patent Application Laid-Open No. 2019-2080

[0006] In order to improve the athletic ability of the sock wearer, it is important to transmit the force of the ligaments involved in the movement of the foot to the ground with as little loss as possible. However, conventionally known socks lack this perspective, making it difficult for the sock wearer to efficiently transmit the force of the ligaments involved in the movement of the foot to the ground when exercising.

[0007] The present disclosure has been made in consideration of such problems, and aims to provide socks that can efficiently transmit the force of the ligaments involved in the movement of the foot to the ground when the wearer exercises.

[0008] One aspect of the present disclosure relates to a sock having an anti-slip portion on the outer surface of the sock bottom that comes into contact with the sole of the wearer's foot when the sock is worn, and / or on the inner surface, which is the surface opposite the outer surface of the sock bottom, and the anti-slip portion includes a first anti-slip portion formed on the outer surface and / or inner surface of the sock bottom along the course of the plantar fascia on the sole of the foot.

[0009] The sock has the above-described configuration, and therefore, when the wearer exercises, the sock allows the force of the ligaments involved in the movement of the foot to be efficiently transmitted to the ground.

[0011] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. [1] A sock having an anti-slip portion on the outer surface of the sole of the sock that comes into contact with the sole of the wearer's foot when the sock is worn, and / or on the inner surface of the sock that is the surface opposite the outer surface of the sock sole, the anti-slip portion including a first anti-slip portion formed on the outer surface and / or the inner surface of the sock sole along the course of the plantar fascia on the sole of the foot.

[0012] The plantar fascia f1 on the sole of the foot shown in Figure 11(a) is a ligament that spans the entire sole and plays a role in balancing foot movement. The anti-slip portion of the sock described in [1] above includes a first anti-slip portion formed on the outer and / or inner surface of the sock bottom along the course of the plantar fascia on the sole. Therefore, the sock described in [1] above allows the force of the ligaments involved in foot movement to be efficiently transmitted to the ground when the wearer exercises.

[0013] [2] The sock described in [1], wherein the anti-slip portion further includes a second anti-slip portion formed on the outer surface and / or inner surface of the sock bottom along the course of the long plantar ligament on the sole of the foot.

[0014] The long plantar ligament f2 on the sole of the foot, as shown in Figures 11(b) and 12(a), is connected (attached) to the flexor hallucis brevis f3, adductor hallucis (oblique head) f4, flexor digitorum brevis f5, opponens digiti minimi f6, and peroneus brevis f7, all of which are important for transmitting kinetic energy backward when the sole of the foot touches the ground during walking or running (see Figures 12(b) to (f)). These muscles are closely involved in the formation and stability of the longitudinal arch of the foot (plantar arch). The non-slip portion of the sock described in [2] above further includes a second non-slip portion formed on the outer and / or inner surface of the sock bottom along the course of the long plantar ligament on the sole. Therefore, in the sock described in [2] above, the increased thickness provided by the second anti-slip portion formed to overlap the area corresponding to the long plantar ligament on the outer and / or inner side of the sock sole has the effect of lifting the arch of the foot, thereby improving the stability of the longitudinal arch of the foot. Furthermore, in the sock described in [2] above, the improved stability of the longitudinal arch also improves the movement of the anterior arch muscles. Therefore, the sock described in [2] above allows the force of the ligaments involved in the movement of the foot to be more efficiently transmitted to the ground when the wearer exercises.

[0015] [3] The sock described in [2], wherein the thickness of the second anti-slip portion is greater than the thickness of the first anti-slip portion, or the thickness of the portion of the sock bottom surface where the second anti-slip portion is formed is greater than the thickness of the surrounding area of ​​that portion of the sock bottom surface.

[0016] In the sock described in [3] above, if the second anti-slip portion is thicker than the first anti-slip portion, the effect of the thicker second anti-slip portion in lifting the arch of the foot is enhanced, further improving the stability of the longitudinal arch of the foot. On the other hand, in the sock described in [3] above, if the thickness of the portion of the sock bottom where the second anti-slip portion is formed is thicker than the thickness of the surrounding area of ​​that portion of the sock bottom, even if the second anti-slip portion is formed to be the same thickness as the first anti-slip portion, the thicker portion of the sock bottom where the second anti-slip portion is formed will enhance the effect of the second anti-slip portion in lifting the arch of the foot, further improving the stability of the longitudinal arch of the foot. Therefore, the sock described in [3] above can ensure the effects of the sock described in [2] above.

[0017] [4] The sock described in any one of [1] to [3], wherein the anti-slip portion further includes a third anti-slip portion formed on the outer surface and / or inner surface of the sock bottom along the course of the superficial transverse metatarsal ligament on the sole of the foot.

[0018] The superficial transverse metatarsal ligament f8 on the sole of the foot, shown in Figure 13, is connected to the adductor hallucis (transverse head) f9 and plays a role in maintaining the transverse arch of the foot, which is essential for the movement of the big toe through the little toe. The multiple anti-slip portions in the sock described in [4] above further include a third anti-slip portion formed on the lateral and / or medial sides of the sock sole along the course of the superficial transverse metatarsal ligament on the sole. Therefore, in the sock described in [4] above, the repulsive force of the third anti-slip portion generates a force that pushes the superficial transverse metatarsal ligament toward the dorsum of the foot, thereby maintaining the transverse arch of the foot and facilitating the extension of all toes, allowing the toes to firmly grip the ground. Therefore, the sock described in [4] above allows the force of the ligaments involved in foot movement to be more efficiently transmitted to the ground when the wearer exercises.

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

[0020] The sesamoid bone f10 of the great toe shown in Figures 14(a) and 15(a) functions as a tendon pulley, facilitating the smooth movement of joints and ligaments. The multiple anti-slip portions in the sock described in [5] above further include a fourth anti-slip portion formed on the outer and / or inner sides of the sock sole to sandwich the sesamoid bone position corresponding to the wearer's great toe from the front-to-back direction of the sock. Therefore, with the sock described in [5] above, the fourth anti-slip portion sandwiches and stabilizes the sesamoid bone of the great toe from the front-to-back direction of the sock, improving the function of the sesamoid bone. Therefore, with the sock described in [5] above, the force of the ligaments involved in foot movement can be more efficiently transmitted to the ground when the sock wearer exercises. Furthermore, the sock described in [5] above is expected to be effective in preventing sesamoiditis and other conditions.

[0021] [6] A sock according to any one of [1] to [5], having an un-slip area where the anti-slip portion is not formed in the area corresponding to the plantar arch of the sole on the outer and / or inner surface of the sock bottom.

[0022] As shown in FIG. 16 , the plantar arch of the sole is where the tendons (flexor digitorum longus f12 and flexor hallucis longus f13) cross. Compression of this area restricts foot movement. The sock described in [6] above has a non-slip area on the outer and / or inner sole of the sock, corresponding to the plantar arch of the sole. Therefore, the presence of the non-slip area in the sock described in [6] above makes it less likely that the non-slip area will compress the area where the tendons cross. Therefore, the sock described in [6] above allows the ligament force involved in foot movement to be more efficiently transmitted to the ground when the sock wearer exercises.

[0023] [7] The sock according to any one of [1] to [6], having a first taping knitting portion formed by taping knitting in an area corresponding to the inferior extensor retinaculum and inferior peroneal retinaculum of the sock wearer's foot.

[0024] The inferior extensor retinaculum f14 and inferior peroneal retinaculum f15 shown in Figure 17 serve to suspend the longitudinal arch of the foot from above. The sock described in [7] above has a first knitted taping portion formed by knitting taping in areas corresponding to the inferior extensor retinaculum and inferior peroneal retinaculum of the sock wearer's foot. Therefore, with the sock described in [7] above, the first knitted taping portion can protect the inferior extensor retinaculum and inferior peroneal retinaculum of the foot and increase the stability of the longitudinal arch of the foot. Therefore, with the sock described in [7] above, the force of the ligaments involved in foot movement can be more efficiently transmitted to the ground when the sock wearer exercises.

[0025] [8] A sock as described in [7], further comprising a second taping knitting portion extending from the first taping knitting portion and formed by taping knitting, the second taping knitting portion being formed in a region corresponding to a route that runs from the inferior extensor retinaculum of the sock wearer's foot, passes above the lateral malleolus of the sock wearer's foot, surrounds the lateral side of the head of the sock wearer's Achilles tendon, passes above the medial malleolus of the sock wearer's foot, and returns to the inferior extensor retinaculum.

[0026] When a human ankle sprains, it is usually injured by inversion. The sock described in [8] above has the second knitted taping portion described above in addition to the first knitted taping portion. Therefore, with the sock described in [8] above, the first knitted taping portion promotes the formation of the longitudinal arch of the foot, making it easier to suppress inversion of the ankle. In addition, the second knitted taping portion is configured to end slightly toward the head, away from the insertion point of the Achilles tendon, which moves frequently during exercise, so it is less likely to interfere with the movement of the Achilles tendon itself.

[0027] [9] The sock according to any one of [1] to [8], wherein the toe portion of the sock tip is formed in a rounded shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer all at once, or in a tabi shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer separately, or in a four-finger shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer separately, or in a five-finger shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer separately.

[0028] In the sock described in [9], if the toe section at the end of the sock is formed in a rounded shape that covers the big toe, index finger, middle finger, ring finger, and little toe of the wearer, the toes can be fully extended. Therefore, in this case, the force of the toes, which is a natural human ability to "grip the ground while walking," can be efficiently transmitted to the ground, which is particularly effective when walking, strolling, running, and other sports.

[0029] In the sock described in [9], if the toe section at the end of the sock is formed in the shape of a tabi sock that separately covers the big toe and the index, middle, ring, and little toes of the wearer's foot, this allows the big toe to move freely, making it more suitable for sports that require fast foot movement. It is also useful for sports where the ground is uneven, such as table tennis and badminton, or sports that put pressure on the big toe, such as skiing.

[0030] In particular, in sports that involve lunging forward, such as rugby, sprinting, and the long jump, regular socks cause the little toe to move outward when striking the ground. In contrast, the sock described in [9] has a four-pronged toe that covers the wearer's big toe, index finger, middle finger, ring finger, and little toe separately. This secures the little toe to the ring finger, allowing for efficient transfer of vertical kinetic energy to the ground. This enhances the sock's suitability for sports that involve lunging forward, such as rugby, sprinting, and the long jump.

[0031] In the socks described in [9], if the toe part at the tip of the sock is formed in a five-finger shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the wearer's foot separately, it can protect each toe while preventing stuffiness between the toes, which is common in people with hyperhidrosis, and in cases where there are problems such as ingrown toenails, and can transmit mechanical force to the ground without interfering with the mechanical conduction of ligaments during sports.

[0032]

[10] A sock as described in any one of [1] to [8], wherein the toe portion of the sock tip is formed in a rounded shape so as to cover the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer all at once, and the non-slip portion further includes a rounded non-slip portion formed in a single area that includes all of the areas corresponding to the pads of the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer on the outer and / or inner surfaces of the sock bottom.

[0033] According to the sock described in

[10] , the rounded toe anti-slip part can enhance the effect of the rounded toe at the tip of the sock.

[0034]

[11] A sock as described in any one of [1] to [8], wherein the toe portion of the sock tip is formed in the form of tabi socks that separately cover the big toe and the index, middle, ring, and little toes of the sock wearer, and the non-slip portion further includes tabi-style non-slip portions formed in two areas on the outer and / or inner sides of the sock bottom: an area corresponding to the pad of the big toe of the sock wearer, and a single area including all of the areas corresponding to the pads of the index, middle, ring, and little toes.

[0035] According to the sock described in

[11] , the tabi-style non-slip portion enhances the effect of the toe portion of the sock being formed in the tabi style.

[0036]

[12] A sock as described in any one of [1] to [8], wherein the toe portion of the sock tip is formed in a four-pronged shape to separately cover the big toe, index finger, middle finger, ring finger and little finger of the sock wearer, and the anti-slip portion further includes four-pronged anti-slip portions formed in four areas on the outer and / or inner surface of the sock sole: an area corresponding to the pad of the big toe of the sock wearer, an area corresponding to the pad of the index finger, an area corresponding to the pad of the middle finger, and a single area including all of the areas corresponding to the pads of the ring finger and little finger.

[0037] According to the sock described in

[12] , the four-pronged anti-slip part can enhance the effect of the toe part at the tip of the sock being formed in a four-pronged shape.

[0038]

[13] A sock as described in any one of [1] to [8], wherein the toe portion of the sock tip is formed in a five-finger shape that separately covers the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer, and the anti-slip portion further includes five five-finger anti-slip portions formed in five areas on the outer and / or inner surface of the sock sole: an area corresponding to the pad of the big toe, an area corresponding to the pad of the index finger, an area corresponding to the pad of the middle finger, an area corresponding to the pad of the ring finger, and an area corresponding to the pad of the little finger.

[0039] According to the sock described in

[13] , the five-fingered anti-slip portion enhances the effect of the toe portion at the tip of the sock being formed in a five-fingered shape.

[0040] [Details of the embodiment of the present disclosure] Next, specific examples of socks according to the embodiment of the present disclosure will be described in detail with reference to the drawings. The present disclosure is not limited to the following examples. For example, in the following, for the sake of simplicity, a sock having all of the above-described configurations will be used as an example, but the above-described configurations can be combined in any desired manner.

[0041] (Embodiment 1) A sock according to embodiment 1 will be described with reference to Figures 1 to 17. In embodiment 1, the toe side of the sock 1 is referred to as the front of the sock, the heel side of the sock 1 as the rear, the width direction of the sock 1 as the sock width direction, the instep side of the sock 1 as the upper side, the sole side of the sock 1 as the lower side, the arch side of the sock as the inner side, and the side opposite the inner side of the sock as the outer side. The following examples will be described using a sock 1 to be worn on the right foot of a sock wearer. The configuration of the sock 1 to be worn on the left foot of a sock wearer can be achieved by simply reversing the configuration of the sock 1 for the right foot. For ease of understanding, Figures 1 and 2 show simplified projections of the plantar fascia f1, superficial transverse metatarsal ligament f8, and sesamoid bone f10 of the big toe of the sock wearer's right foot onto the sock sole 11. 1 to 3 are enlarged views of Fig. 4 to 10. Fig. 11 to 17 are diagrams that schematically show various ligaments, bones, muscles, etc. in a person's right foot, and these can be used as appropriate for reference.

[0042] As illustrated in Figures 1 to 10, the sock 1 of embodiment 1 has anti-slip portions 12 on both the outer surface 11o of the sock bottom 11 that comes into contact with the sole of the wearer's foot when the sock is worn, and the inner surface 11i of the sock bottom 11.

[0043] This type of non-slip portion 12 can be formed by applying a non-slip material made of a known polymer material (such as rubber, elastomer, or resin, more specifically, silicone rubber or silicone elastomer) used in known socks and gloves to the outer surface 11o and inner surface 11i of the sock sole 11. Here, silicone rubber, for example, can be used as the non-slip material, but any non-slip material that can provide non-slip functionality can be used. The inner surface 11i of the sock sole 11 is the surface opposite the outer surface 11o of the sock sole 11. In other words, the outer surface 11o of the sock sole 11 can also be said to be the surface opposite the inner surface 11i of the sock sole 11. The inner surface 11i of the sock sole 11 can also be said to be the surface that comes into contact with the skin of the sole of the wearer's foot.

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

[0045] Specifically, the first anti-slip portion 121 can be formed by applying an anti-slip treatment to the outer surface 11o and inner surface 11i of the sock bottom 11 along the path of the plantar fascia f1. Following the path of the plantar fascia f1 means overlapping with the plantar fascia f1 projected onto the sock bottom 11, but does not necessarily mean strictly following the shape of the plantar fascia f1 projected onto the sock bottom 11. The same interpretation applies to "following the path" in the following description. More specifically, the first anti-slip portion 121 can be configured to include multiple polygonal (here, rectangular) anti-slip portions for the plantar fascia 121a and multiple round anti-slip portions for the plantar fascia 121b. The angular shape of the plantar fascia anti-slip portions 121a has the advantage of making it easier to ensure an area that overlaps with the plantar fascia f1. Furthermore, the round anti-slip portion 121b for the plantar fascia is formed in a round shape (dot-like), which has the advantage of making it easier to prevent the sock 1 from slipping out of position when the wearer is exercising.

[0046] As long as the first anti-slip portion 121 includes an anti-slip portion arranged to overlap the plantar fascia f1, it may also include an anti-slip portion that protrudes from the plantar fascia f1. For example, Figures 1 and 2 show examples of angular plantar fascia anti-slip portion 121a that is arranged at a position closer to the front of the sock than approximately halfway in the front-to-back direction, overlapping with the plantar fascia f1 but not protruding from the plantar fascia f1, and angular plantar fascia anti-slip portion 121a that is arranged to overlap with the plantar fascia f1 but protrude from the plantar fascia f1.

[0047] 1 and 2 also illustrate an example of a round anti-slip portion for plantar fascia 121b positioned rearward of the sock from approximately halfway in the front-to-rear direction, overlapping the plantar fascia f1 but not extending beyond the plantar fascia f1. In addition to the round anti-slip portion for plantar fascia 121b, Figures 1 and 2 also illustrate an example in which, in the heel region of the sock 1, multiple round anti-slip portions for plantar fascia 121c are positioned around the periphery of the multiple round anti-slip portions for plantar fascia 121b, but not overlapping the plantar fascia f1, in order to enhance the anti-slip effect. The round anti-slip portion for plantar fascia 121c can also be positioned outside the sock sole 11, for example, behind the heel of the sock 1, so as to extend upward.

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

[0049] Specifically, the second anti-slip portion 122 can be formed by applying an anti-slip treatment to the outer surface 11o and inner surface 11i of the sock sole 11 along the path of the long plantar ligament f2. More specifically, the second anti-slip portion 122 can be formed in a shape similar to the outline of the long plantar ligament f2 so as to overlap the area corresponding to the long plantar ligament f2. In the first embodiment, the second anti-slip portion 122 is formed from a single anti-slip portion.

[0050] As shown in Figure 12, the flexor hallucis brevis f3, adductor hallucis (oblique head) f4, flexor digitorum minimi brevis f5, opponens digiti minimi f6, and peroneus brevis f7 are connected (attached) to the long plantar ligament f2, and these muscles are closely involved in the formation and stability of the longitudinal arch of the foot (plantar arch). The thickness of the second non-slip portion 122 is preferably greater than that of the first non-slip portion 121, from the viewpoint of enhancing the effect of the thicker second non-slip portion 122 in lifting the arch of the foot and improving the stability of the longitudinal arch. However, the thickness of the second non-slip portion 122 can also be made equal to that of the first non-slip portion 121. In this case, the thickness of the portion of the sock bottom 11 where the second non-slip portion 122 is formed is preferably greater than the thickness of the surrounding area of ​​the sock bottom 11. With this configuration, in addition to the thickness provided by the formation of the second anti-slip portion 122, the increased thickness of the portion of the sock sole 11 where the second anti-slip portion 122 is formed enhances the effect of lifting the arch of the foot and improves the stability of the longitudinal arch of the foot, even if the thickness of the second anti-slip portion 122 is the same as that of the first anti-slip portion 121. In this case, if the thickness of the second anti-slip portion 122 is further formed to be thicker than the thickness of the first anti-slip portion 121, the above-mentioned effect can be further enhanced.

[0051] It should be noted that the plantar fascia f1 and the long plantar ligament f2 overlap when projected onto the sock sole surface 11. In the sock 1 of embodiment 1, in the region of the sock sole surface 11 corresponding to the plantar fascia f1 where the second anti-slip portion 122 that runs along the course of the long plantar ligament f2 should be formed, the first anti-slip portion 121 is not formed, and the second anti-slip portion 122 is formed preferentially.

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

[0053] Specifically, the third anti-slip portion 123 can be formed by applying an anti-slip treatment to the lateral surface 11o and medial surface 11i of the sock sole 11 along the course of the superficial transverse metatarsal ligament (f8). As shown in FIG. 13 , the superficial transverse metatarsal ligament (f8) is connected to the adductor hallucis (transverse head) (f9), which is closely related to the formation and stability of the transverse arch of the foot. More specifically, the third anti-slip portion 123 can be configured to include multiple rounded anti-slip portions 123b for the superficial transverse metatarsal ligament. The rounded anti-slip portions 123b for the superficial transverse metatarsal ligament have the advantage of exerting a repulsive force to easily lift the superficial transverse metatarsal ligament (f8) and maintain the transverse arch, even when the direction or angle of pressure applied to the third anti-slip portion 123 by the sole of the foot changes.

[0054] The round anti-slip portion 123b for the superficial metatarsal ligament can be configured so that its outer diameter gradually or stepwise decreases from the inside of the sock 1 toward the outside of the sock 1. This configuration has the advantage of making it easier to follow the path of the superficial metatarsal ligament f8. Specifically, Figures 1 and 2 show an example in which the outer diameter of the outer side of the sock 1 is smaller than that of the inner side, with the boundary being the part of the sock sole 11 that corresponds to the base of the middle toe. In other words, in Figures 1 and 2, the round anti-slip portion 123b for the superficial metatarsal ligament is configured so that its outer diameter gradually (in one step, in this case) decreases from the inside of the sock 1 toward the outside of the sock 1. Figures 1 and 2 show an example in which the outer diameter of the round anti-slip portion 123b for the superficial metatarsal ligament, which is located inside the sock 1 from the above-mentioned border, is formed to be equal to the outer diameter of the round anti-slip portion 121b for the plantar fascia in the first anti-slip portion 121, but this is not limited to this.

[0055] It should be noted that the plantar fascia f1 and the superficial transverse metatarsal ligament f8 overlap when projected onto the sock bottom surface 11. In the sock 1 of embodiment 1, in the region of the sock bottom surface 11 corresponding to the plantar fascia f1, where the third anti-slip portion 123 that runs along the course of the superficial transverse metatarsal 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 illustrated in Figures 1 and 2, the anti-slip portion 12 may further include a fourth anti-slip portion 124 formed on the outer surface 11o and inner surface 11i of the sock bottom 11 so as to sandwich the sesamoid position P corresponding to the sesamoid bone f10 of the sock wearer's big toe (see Figures 14(a) and 15(b)) from the front-to-back direction of the sock.

[0057] Specifically, the fourth anti-slip portion 124 can be composed of a pair of lateral sesamoid anti-slip portions 124o that sandwich the lateral sesamoid position Po corresponding to the lateral sesamoid bone f10o of the big toe shown in Fig. 14(a) from the front-to-back direction of the sock, and a pair of medial sesamoid anti-slip portions 124i that sandwich the medial sesamoid position Pi corresponding to the medial sesamoid bone f10i of the big toe from the front-to-back direction of the sock. The lateral sesamoid anti-slip portions 124o can be positioned so as to overlap areas of the sock sole 11 that correspond to the lateral phalangeal sesamoid ligament f11o1 and the lateral metatarsal sesamoid ligament f11o2 shown in Fig. 14(b) and Fig. 14(c). Similarly, the anti-slip portion 124i for the medial sesamoid can be positioned to overlap the area on the sock bottom 11 corresponding to the medial phalangeal sesamoid ligament f11i1 and the medial metatarsal sesamoid ligament f11i2 shown in Figures 15(b) and 15(c).

[0058] It should be noted that the plantar fascia 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 overlap when projected onto the sock sole 11. In the sock 1 of embodiment 1, in the region of the sock sole 11 corresponding to the plantar fascia f1 where the fourth anti-slip portion 124 that sandwiches the sesamoid position P from the front-to-back direction of the sock should be formed, the first anti-slip portion 121 is not formed, and the fourth anti-slip portion 124 is formed first.

[0059] As illustrated in Figures 1 and 2, the sock 1 of embodiment 1 can be configured to have non-slip areas 13, where no non-slip portion 12 is formed, in the areas corresponding to the plantar arch (arch) of the sole of the foot on the outer surface 11o and inner surface 11i of the sock bottom 11.

[0060] The sock 1 may have a non-slip area 13 in a part of the area on the sock bottom surface 11 corresponding to the plantar arch lid, or may have a non-slip area 13 in the entire area on the sock bottom surface 11 corresponding to the plantar arch lid.

[0061] As illustrated in Figures 4 to 10, the sock 1 of embodiment 1 can be configured to have a first knitted taping portion 141 formed by knitting taping in an area corresponding to the inferior extensor retinaculum f14 and inferior peroneal retinaculum f15 of the sock wearer's foot as shown in Figure 17. "Formed by knitting taping" means that the sock fabric is knitted to provide a taping effect. The same applies below. The first knitted taping portion 141 may be formed only on the sock upper, or may be formed not only on the sock upper but also with its end positioned on the sock sole 11.

[0062] 4 to 10 , the sock 1 of embodiment 1 can further include a second knitted taping portion 142 extending from the first knitted taping portion 141 and formed by knitting taping. Specifically, the second knitted taping portion 142 is formed in a region corresponding to the route that runs from the inferior extensor retinaculum f14 of the sock wearer's foot, passes above the lateral malleolus f16o of the sock wearer's foot, circumnavigates the lateral side of the head of the sock wearer's Achilles tendon f17, passes above the medial malleolus f16i of the sock wearer's foot, and returns to the inferior extensor retinaculum f14, as shown in FIG. 17 . The star symbol Si in FIG. 7 indicates the position corresponding to the medial malleolus f16i of the sock wearer's foot, and the star symbol So in FIG. 8 indicates the position corresponding to the lateral malleolus f16o of the sock wearer's foot.

[0063] 4 to 10, the sock 1 of embodiment 1 can be configured to have a third knitted taping portion 143 formed by taping in an area corresponding to the periphery of the sock 1 in the sock width direction, that is, an area that goes all the way around from the instep side of the sock 1 to the sock back side and from the sock back side to the instep side of the sock 1. This configuration has the advantage of enhancing the taping effect of the first knitted taping portion 141.

[0064] In the sock 1 of the first embodiment, the toe portion 15 at the tip of the sock 1 is formed to cover the big toe, index finger, middle finger, ring finger, and little toe of the sock wearer all at once, as illustrated in FIGS. 1 and 2 . Hereinafter, this configuration will be referred to as the round-toe configuration. The toe portion 15 at the tip of the sock 1 is not limited to the round-toe configuration, and may alternatively be formed to cover the big toe, index finger, middle finger, ring finger, and little toe separately, as illustrated in FIG. 3( a). Hereinafter, this configuration will be referred to as the tabi configuration. The toe portion 15 at the tip of the sock 1 may alternatively be formed to cover the big toe, index finger, middle finger, ring finger, and little toe separately, as illustrated in FIG. 3( b). Hereinafter, this configuration will be referred to as the four-prong configuration. Alternatively, the toe portion 15 at the tip of the sock 1 may be formed to cover the big toe, index finger, middle finger, ring finger, and little finger of the wearer separately, as shown in Fig. 3(c) . Hereinafter, this configuration will be referred to as a five-toe configuration.

[0065] In the case of the rounded toe shape exemplified in Figures 1 and 2, from the viewpoint of enhancing the effect of the rounded toe shape described above, the non-slip portion 12 preferably includes a rounded toe non-slip portion 125 formed in a single region that includes all of the regions corresponding to the pads of the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer on the outer surface 11o and inner surface 11i of the sock bottom 11.

[0066] Furthermore, in the case of the tabi style illustrated in FIG. 3( a), from the viewpoint of enhancing the effect of the tabi style described above, the anti-slip portion 12 preferably has anti-slip portions 125a for tabi style formed in two areas: an area corresponding to the pad of the big toe of the sock wearer on the outer surface 11o and inner surface 11i of the sock bottom 11, and a single area including all of the areas corresponding to the pads of the index finger, middle finger, ring finger, and little finger.

[0067] Furthermore, in the case of the four-pronged shape illustrated in FIG. 3( b), in order to enhance the effect of the four-pronged shape described above, the anti-slip portion 12 preferably has four-pronged anti-slip portions 125b formed in four regions on the outer surface 11o and inner surface 11i of the sock bottom 11: a region corresponding to the pad of the big toe of the sock wearer; a region corresponding to the pad of the index finger; a region corresponding to the pad of the middle finger; and a single region including all of the regions corresponding to the pads of the ring finger and little finger.

[0068] Furthermore, in the case of the five-finger configuration exemplified in FIG. 3( c), from the viewpoint of enhancing the effect of the five-finger configuration described above, the anti-slip portion 12 may have five-finger configuration anti-slip portions 125c formed in five regions on the outer surface 11o and inner surface 11i of the sock bottom 11, namely, a region corresponding to the pad of the big toe of the sock wearer, a region corresponding to the pad of the index finger, a region corresponding to the pad of the middle finger, a region corresponding to the pad of the ring finger, and a region corresponding to the pad of the little finger.

[0069] The sock 1 according to the above-described design and specifications can be manufactured by appropriately combining known manufacturing methods.

[0070] (Embodiment 2) A sock according to embodiment 2 will be described. Note that, of the symbols used in embodiment 2 and subsequent embodiments, the same symbols as those used in the previous embodiments represent the same components as those in the previous embodiments, unless otherwise specified.

[0071] The sock 1 of embodiment 2 differs from the sock 1 of embodiment 1 in that it has an anti-slip portion 12 on the outer surface 11o of the sock bottom 11, which comes into contact with the sole of the wearer's foot when the sock is worn, but does not have an anti-slip portion 12 on the inner surface 11i of the sock bottom 11. In other words, while the sock 1 of embodiment 1 described above is an example in which the anti-slip portion 12 is provided on both the outer surface 11o and the inner surface 11i of the sock bottom 11, the sock 1 of embodiment 2 is an example in which the above-mentioned anti-slip portion 12 is provided only on the outer surface 11o of the sock bottom 11. The rest of the configuration is the same as embodiment 1.

[0072] Although the sock 1 of embodiment 2 is less effective than the sock 1 of embodiment 1, it can efficiently transmit the force of the ligaments involved in the movement of the sock wearer's foot to the ground when the wearer exercises. Furthermore, the sock 1 of embodiment 2 does not have the anti-slip portion 12 on the inner surface 11i of the sock bottom 11, which improves sock manufacturability compared to the sock 1 of embodiment 1. Therefore, the sock 1 of embodiment 2 can be made more productive and less expensive. Furthermore, the sock 1 of embodiment 2 has the anti-slip portion 12 only on the outer surface 11o of the sock bottom 11, which has the advantage of providing better slip processing properties for the anti-slip portion 12 compared to the sock 1 of embodiment 3 described below. Other effects are the same as those of embodiment 1.

[0073] Third Embodiment A sock according to a third embodiment will be described.

[0074] The sock 1 of embodiment 3 differs from the sock 1 of embodiment 1 in that it has an anti-slip portion 12 on the inner surface 11i of the sock bottom 11, which comes into contact with the sole of the wearer's foot when the sock is worn, but does not have an anti-slip portion 12 on the outer surface 11o of the sock bottom 11. In other words, while the sock 1 of embodiment 1 described above is an example in which the anti-slip portion 12 is provided on both the outer surface 11o and the inner surface 11i of the sock bottom 11, the sock 1 of embodiment 3 is an example in which the above-mentioned anti-slip portion 12 is provided only on the inner surface 11i of the sock bottom 11. The rest of the configuration is the same as embodiment 1.

[0075] Although the sock 1 of embodiment 3 is less effective than the sock 1 of embodiment 1, it can efficiently transmit the force of the ligaments involved in the movement of the sock wearer's foot to the ground when the wearer exercises. Also, because the sock 1 of embodiment 3 does not have the anti-slip portion 12 on the outer surface 11o of the sock sole 11, the appearance of the outer surface 11o of the sock sole 11 can be made similar to that of a regular sock. Other effects are the same as those of embodiment 1.

[0076] The present disclosure is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present disclosure. Furthermore, the configurations shown in the above-described embodiments can be combined in any manner.
