Description

CROSS-REFERENCE TO RELATED APPLICATIONS

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

The present disclosure relates to socks.

Conventionally, socks have been known that have anti-slip sections formed on the bottom surface to prevent the soles of the feet from slipping.

For example, the prior 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 the 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 outer side opening toward the toes 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 on the sole is 50 degrees or more and less than 100 degrees.

JP 2019-2080 A

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, conventional socks lack this perspective, making it difficult for them to efficiently transmit the force of the ligaments involved in the movement of the foot when the sock wearer is exercising.

This 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 when the wearer exercises to the ground.

One aspect of the present disclosure is
The sock has an anti-slip portion on an outer surface of the sock bottom that contacts the sole of the wearer's foot when the sock is worn and/or on an inner surface that is the surface opposite to the outer surface of the sock bottom,
The anti-slip portion is
A first anti-slip portion is formed on the outer surface and/or the inner surface of the sock bottom along the course of the plantar fascia on the sole of the foot.
It's in the stockings.

The sock has the above-mentioned configuration. Therefore, the sock enables the force of the ligaments involved in the movement of the foot when the wearer of the sock exercises to be efficiently transmitted to the ground.

[Description of the embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
[1]
The sock has an anti-slip portion on an 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 an inner surface that is the surface opposite to the outer surface of the sock bottom,
The anti-slip portion is
A first anti-slip portion is formed on the outer surface and/or the inner surface of the sock bottom along the course of the plantar fascia on the sole of the foot.
socks.

The plantar fascia f1 on the sole 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 in the sock described in [1] above includes a first anti-slip portion formed on the outer and/or inner side of the sole of the sock along the course of the plantar fascia on the sole. Therefore, the sock described in [1] above makes it possible to efficiently transmit the force of the ligaments involved in the movement of the foot when the sock wearer exercises to the ground.

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

The long plantar ligament f2 in the sole shown in Figures 11(b) and 12(a) is connected (attached) to the flexor hallucis brevis f3, adductor hallucis (clini) f4, flexor digitorum brevis f5, opponens digiti minimi f6, and peroneus brevis f7, 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 are strongly involved in the structure and stability of the longitudinal arch of the foot. The anti-slip portion in the sock described in [2] above further includes a second anti-slip portion formed on the outer and/or inner side of the sock bottom along the course of the long plantar ligament in the sole. Therefore, in the sock described in [2] above, the increased thickness due to 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 bottom can have the effect of lifting the arch of the foot, thereby improving the stability of the longitudinal arch of the foot. Furthermore, the sock described in [2] above can improve the movement of the anterior cruciate ligaments by improving the stability of the longitudinal arch. Therefore, the sock described in [2] above can more efficiently transmit the force of the ligaments involved in the movement of the foot to the ground when the wearer exercises.

[3]
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 the portion of the sock bottom surface.
The socks described in [2].

In the sock described in [3] above, if the thickness of the second anti-slip portion is configured to be thicker than the thickness of the first anti-slip portion, the above-mentioned effect of lifting the arch of the foot by the thickened second anti-slip portion 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, if the thickness of the part of the sock bottom surface where the second anti-slip portion is formed is configured to be thicker than the thickness of the surrounding part of the sock bottom surface, even if the thickness of the second anti-slip portion is formed to be equal to the thickness of the first anti-slip portion, the above-mentioned effect of lifting the arch of the foot by the second anti-slip portion is enhanced because the part of the sock bottom surface where the second anti-slip portion is formed is thick, 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 ensured.

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

The superficial transverse metatarsal ligament f8 on the sole shown in FIG. 13 is connected to the adductor hallucis muscle (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 to the little toe. The multiple anti-slip parts in the sock described in [4] above further include a third anti-slip part formed on the outer surface and/or inner surface of the sole of the sock 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 part generates a force that pushes the superficial transverse metatarsal ligament toward the dorsum of the foot, so that the transverse arch of the foot is maintained and all the toes are easily stretched, allowing the toes to firmly grip the ground. Therefore, according to the sock described in [4] above, the force of the ligaments involved in the movement of the foot when the sock wearer exercises can be transmitted to the ground more efficiently.

[5]
The anti-slip portion is
The sock further includes a fourth anti-slip portion formed on the outer side and/or the inner side of the sock bottom so as to sandwich a sesamoid bone position corresponding to the sesamoid bone of the first toe of the sock wearer from the front-rear direction of the sock.
A sock according to any one of [1] to [4].

The sesamoid bone f10 in the big toe shown in FIG. 14(a) and FIG. 15(a) acts as a pulley for the tendons, facilitating the movement of the joints and ligaments. The multiple anti-slip parts in the sock described in [5] above further include a fourth anti-slip part formed on the outer surface and/or inner surface of the sock bottom so as to sandwich the sesamoid bone position corresponding to the sesamoid bone in the big toe of the sock wearer from the front-rear direction of the sock. Therefore, according to the sock described in [5] above, the fourth anti-slip part sandwiches the sesamoid bone in the big toe from the front-rear direction of the sock, stabilizing it, and improving the role of the sesamoid bone. Therefore, according to the sock described in [5] above, it is possible to more efficiently transmit the force of the ligaments involved in the movement of the foot when the sock wearer exercises to the ground. In addition, according to the sock described in [5] above, it is expected that the effect of preventing sesamoiditis and the like can be achieved.

[6]
The sock has an unformed non-slip area in which the non-slip portion is not formed in an area on the outer side and/or the inner side of the sole of the sole of the foot corresponding to the plantar arch of the sole of the foot.
A sock according to any one of [1] to [5].

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. When this area is compressed, the movement of the foot is restricted. In the sock described in [6] above, a non-slip area where no anti-slip portion is formed is provided in the area corresponding to the plantar arch of the sole on the outer and/or inner sides of the sock bottom. Therefore, in the sock described in [6] above, the presence of the non-slip area makes it difficult for the anti-slip portion to compress the area where the tendons cross. Therefore, the sock described in [6] above makes it possible to more efficiently transmit the force of the ligaments involved in the movement of the foot when the sock wearer exercises to the ground.

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

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

[8]
A second taping knit portion extends from the first taping knit portion and is formed by taping knitting,
The second taping knitting portion is
The sock wearer's foot is 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, goes around the lateral side of the head of the Achilles tendon of the sock wearer, passes above the medial malleolus of the sock wearer's foot, and returns to the inferior extensor retinaculum.
The socks described in [7].

When a human ankle joint is sprained, it is often injured by inversion. The sock described in [8] above has the above-mentioned second taping knitting part in addition to the first taping knitting part. Therefore, according to the sock described in [8] above, the first taping knitting part promotes the formation of the longitudinal arch of the foot, making it easier to suppress inversion of the ankle joint. In addition, since the second taping knitting part is configured to end slightly toward the head away from the attachment part of the Achilles tendon, which moves a lot when the wearer exercises, it is less likely to interfere with the movement of the Achilles tendon itself.

[9]
The toe part of the sock tip is
The sock is formed in a rounded shape that collectively covers the big toe, index finger, middle finger, ring finger, and little toe of the wearer's foot, or
The socks are formed in a tabi style that covers the big toe, index finger, middle finger, ring finger, and little toe of the wearer's foot separately, or
The sock is formed in a four-pronged shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the wearer's foot separately, or
The sock is formed in a five-toed shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the wearer's foot separately.
A sock according to any one of [1] to [8].

In the sock described in [9], if the toe part at the tip 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 stretched. 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, making it particularly effective when playing sports such as walking, strolling, and running.

In the socks described in [9], if the toe part at the tip of the sock is formed in the form of a tabi that covers the big toe, index finger, middle finger, ring finger, and little toe separately, the big toe can be made free, improving adaptability to sports that involve fast foot movement. It is also useful for sports where the ground is uneven, such as table tennis and badminton, mountain climbing, and sports that put pressure on the big toe, such as skiing.

In particular, in sports such as rugby, sprinting, and long jump, where the wearer lunges forward, normal socks cause the little toe to move outward when the wearer kicks the ground. In contrast, in the socks described in [9], when the toe part at the tip of the sock is formed in 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 separately, the little finger is fixed to the ring finger, so that vertical kinetic energy can be efficiently transmitted to the ground. Therefore, in this case, the adaptability to sports such as rugby, sprinting, and long jump, where the wearer lunges forward, can be improved.

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

[10]
The toe part of the sock tip is
The sock is formed in a rounded shape so as to collectively cover the big toe, index finger, middle finger, ring finger, and little finger of the wearer's foot,
The anti-slip portion is
The sock further includes a rounded toe anti-slip portion formed in a single area including all of the areas corresponding to the pads of the big toe, index finger, middle finger, ring finger, and little finger of the wearer on the outer surface and/or inner surface of the sock bottom.
A sock according to any one of [1] to [8].

According to the sock described in [10], the rounded toe anti-slip portion enhances the effect of the above-mentioned rounded toe at the tip of the sock.

[11]
The toe part of the sock tip is
The socks are formed in a tabi shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the wearer's foot separately,
The anti-slip portion is
The sock further includes anti-slip parts for tabi socks formed in two areas, an area corresponding to the pad of the big toe of the sock wearer on the outer surface and/or the inner surface of the sock bottom, and a single area including all of the areas corresponding to the pads of the index finger, the middle finger, the ring finger, and the little finger.
A sock according to any one of [1] to [8].

According to the sock described in [11], the tabi-style anti-slip portion enhances the effect of the toe portion of the sock tip being formed in a tabi style as described above.

[12]
The toe part of the sock tip is
The sock is formed in a four-pronged shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the wearer's foot separately,
The anti-slip portion is
The sock further includes a four-pronged anti-slip portion formed in four areas on the outer and/or inner sides of the sock bottom, the area corresponding to the pad of the big toe of the sock wearer, the area corresponding to the pad of the index finger, the 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 the little finger,
A sock according to any one of [1] to [8].

According to the sock described in [12], the four-pronged anti-slip portion enhances the effect of the toe portion of the sock tip being formed in a four-pronged shape as described above.

[13]
The toe part of the sock tip is
The socks are formed in a five-toe shape that covers the big toe, index finger, middle finger, ring finger, and little finger of the wearer's foot separately,
The anti-slip portion is
The sock further includes anti-slip parts for five fingers formed in five areas on the outer surface and/or inner surface of the sock sole, the areas being the area corresponding to the pad of the big toe of the wearer, the area corresponding to the pad of the index finger, the area corresponding to the pad of the middle finger, the area corresponding to the pad of the ring finger, and the area corresponding to the pad of the little finger.
A sock according to any one of [1] to [8].

According to the sock described in [13], the five-toed anti-slip portion enhances the effect of the toe portion of the sock tip being formed in a five-toed shape as described above.

[Details of the embodiment of the present disclosure]
Next, specific examples of socks according to embodiments 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, in order to simplify the explanation, a sock having all of the above-mentioned configurations will be used as an example, but the above-mentioned configurations can be combined in any combination.

(Embodiment 1)
The sock of the first embodiment will be described with reference to 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 rear of the sock, the width direction of the sock 1 is the width direction of the sock, the instep side of the sock 1 is the upper side of the sock, the sole side of the sock 1 is the lower side of the sock, the arch side of the sock is the inside of the sock, and the side opposite the inside of the sock is the outside of the sock. In the following examples, the sock 1 applied to the right foot of the sock wearer is used as an example for description. The configuration of the sock 1 applied to the left foot of the sock wearer can be achieved by reversing the configuration of the sock 1 for the right foot. In addition, Figs. 1 and 2 are simplified projections of the plantar fascia f1, superficial transverse metatarsal ligament f8, and sesamoid bone f10 of the first toe of the sock wearer onto the sock bottom surface 11 for the purpose of facilitating understanding. In addition, Figs. 1 to 3 are enlarged relative to Figs. 4 to 10. Additionally, Figures 11 to 17 are schematic diagrams showing various ligaments, bones, muscles, etc. in a person's right foot, and these can be referred to as appropriate.

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.

This type of anti-slip part 12 can be formed by applying an anti-slip material made of a known polymer material (rubber, elastomer, resin, etc., more specifically, silicone rubber, silicone elastomer, etc.) used in known socks and gloves to the outer surface 11o and inner surface 11i of the sock bottom surface 11. Here, for example, silicone rubber can be used as the anti-slip material, but there is no particular limitation as long as the anti-slip material can exhibit an anti-slip function. The inner surface 11i of the sock bottom surface 11 is the surface opposite the outer surface 11o of the sock bottom surface 11. In other words, it can be said that the outer surface 11o of the sock bottom surface 11 is the surface opposite the inner surface 11i of the sock bottom surface 11. It can also be said that the inner surface 11i of the sock bottom surface 11 is the surface that comes into contact with the skin of the sole of the sock wearer's foot.

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).

Specifically, the first anti-slip portion 121 can be configured by applying an anti-slip treatment to the outer surface 11o and inner surface 11i of the sock bottom surface 11 along the course of the plantar fascia f1. Note that "along the course of the plantar fascia f1" means that it overlaps with the plantar fascia f1 projected onto the sock bottom surface 11, and does not require that it strictly follows the shape of the plantar fascia f1 projected onto the sock bottom surface 11. The "along the course" in the following description is interpreted in the same way. More specifically, the first anti-slip portion 121 can be configured to include a plurality of square anti-slip portions 121a for the plantar fascia that have a polygonal shape (here, a square shape) and a plurality of round anti-slip portions 121b for the plantar fascia that have a round shape. The square anti-slip portion 121a for the plantar fascia is formed in a square shape, which has the advantage that it is easy to secure an area that overlaps with the plantar fascia f1. In addition, the round anti-slip portion 121b for the plantar fascia is formed in a round shape (dot shape), which has the advantage of making it easier to prevent the sock 1 from shifting out of position when the wearer is exercising.

The first anti-slip portion 121 may include an anti-slip portion that protrudes from the plantar fascia f1, so long as it includes an anti-slip portion that is arranged to overlap the plantar fascia f1. For example, Figs. 1 and 2 show an angular anti-slip portion for plantar fascia 121a that is arranged to overlap the plantar fascia f1 but not to protrude from the plantar fascia f1, and an angular anti-slip portion for plantar fascia 121a that is arranged to overlap the plantar fascia f1 but protrude from the plantar fascia f1, at a position approximately halfway forward in the front-to-rear direction of the sock.

1 and 2 also show an example of a round anti-slip portion for the plantar fascia 121b that overlaps with the plantar fascia f1 and does not protrude from the plantar fascia f1 at the rear side of the sock from about halfway in the front-to-rear direction. In addition to the round anti-slip portion for the plantar fascia 121b, an example is shown in which multiple round anti-slip portions for the plantar fascia 121c that do not overlap with the plantar fascia f1 are arranged around the outer periphery of multiple round anti-slip portions for the plantar fascia 121b in the heel side region of the sock 1 from the viewpoint of enhancing the anti-slip effect. The round anti-slip portion for the plantar fascia 121c can also be arranged outside the sock bottom surface 11, for example, so as to extend upward from the sock behind the heel part of the sock 1.

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).

Specifically, the second anti-slip portion 122 can be formed by applying an anti-slip treatment to the outer surface 11o and the inner surface 11i of the sock bottom surface 11 along the course of the long plantar ligament f2. More specifically, the second anti-slip portion 122 can be formed in a shape similar to the outer shape 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 of a single anti-slip portion.

12, the long plantar ligament f2 is connected (attached) to the flexor hallucis brevis f3, adductor hallucis (clini) f4, flexor digitorum minimi brevis f5, opponens digiti minimi f6, and peroneus brevis f7, which are strongly involved in the formation and stability of the longitudinal arch 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 enhancing the effect of lifting the arch of the foot by the thickened second anti-slip portion 122 and improving the stability of the longitudinal arch of the foot. However, the thickness of the second anti-slip portion 122 can also be equal to the thickness of the first anti-slip portion 121. In this case, the thickness of the portion of the sock bottom surface 11 on which the second anti-slip portion 122 is formed is preferably formed thicker than the thickness of the surrounding area of the portion of the sock bottom surface 11. According to this configuration, in addition to the thickness provided by the formation of the second anti-slip portion 122, the effect of increasing the thickness of the portion of the sock bottom surface 11 on which the second anti-slip portion 122 is formed can enhance the effect of lifting the arch of the foot and improve the stability of the longitudinal arch of the foot, even if the thickness of the second anti-slip portion 122 is set to be equal to the thickness 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.

When the plantar fascia f1 and the long plantar ligament f2 are projected onto the sock bottom surface 11, they overlap. In the sock 1 of embodiment 1, in the region of the sock bottom surface 11 corresponding to the plantar fascia f1, where the second anti-slip portion 122 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.

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.

Specifically, the third anti-slip portion 123 can be formed by applying an anti-slip treatment to the outer surface 11o and the inner surface 11i of the sock bottom surface 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 muscle (transverse head) f9, which is strongly involved in the formation and stability of the transverse arch of the foot. More specifically, the third anti-slip portion 123 can be formed to include a plurality of round anti-slip portions 123b for the superficial transverse metatarsal ligament, each of which has a round shape. In the third anti-slip portion 123, the round anti-slip portion 123b for the superficial transverse metatarsal ligament has the advantage that it makes it easier to lift the superficial transverse metatarsal ligament f8 by applying a repulsive force and to maintain the transverse arch, even if the direction or angle at which the third anti-slip portion 123 is pressed by the sole of the foot changes.

The round anti-slip portion 123b for the superficial metatarsal ligament can be configured so that the outer diameter gradually or stepwise decreases from the inside of the sock 1 to the outside of the sock 1. This configuration has the advantage of making it easier to follow the course of the superficial metatarsal ligament f8. Specifically, Figs. 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 of the sock 1, with the border being the part of the sock bottom surface 11 that corresponds to the base of the middle toe. In other words, in Figs. 1 and 2, the round anti-slip portion 123b for the superficial metatarsal ligament is configured so that the outer diameter gradually decreases (in one step here) from the inside of the sock 1 to 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 transverse 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.

When the plantar fascia f1 and the superficial metatarsal ligament f8 are projected onto the sock bottom surface 11, they overlap. In the sock 1 of the first embodiment, in the region of the sock bottom surface 11 corresponding to the plantar fascia f1, where the third anti-slip portion 123 should be formed along the course of the superficial metatarsal ligament f8, the first anti-slip portion 121 is not formed, and the third anti-slip portion 123 is formed preferentially.

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 bone position P corresponding to the sesamoid bone f10 (see Figures 14(a) and 15(b)) of the sock wearer's big toe from the front-to-back direction of the sock.

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

When 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 are projected onto the sock bottom surface 11, they overlap. In the sock 1 of embodiment 1, in the region of the sock bottom surface 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 preferentially.

As illustrated in Figures 1 and 2, the sock 1 of embodiment 1 can be configured to have a non-slip area 13 where no anti-slip portion 12 is formed in the area 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 surface 11.

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 cap, or may have a non-slip area 13 in the entire area on the sock bottom surface 11 corresponding to the plantar arch cap.

4 to 10, the sock 1 of embodiment 1 can be configured to have a first taping knit portion 141 formed by taping knitting in an area corresponding to the inferior extensor retinaculum f14 and the inferior peroneal retinaculum f15 of the sock wearer's foot shown in FIG. 17. Formed by taping knitting means that the sock fabric is knitted so that it can exert a taping effect. The same applies below. The first taping knit portion 141 may be formed only on the sock upper part, or may be formed not only on the sock upper part but also so that its end is positioned on the sock bottom surface 11.

4 to 10, the sock 1 of the first embodiment can further include a second taping knitting portion 142 extending from the first taping knitting portion 141 and formed by taping knitting. Specifically, the second taping knitting portion 142 is formed in an area corresponding to a route from the inferior extensor retinaculum f14 of the sock wearer's foot shown in FIG. 17, passing above the lateral malleolus f16o of the sock wearer's foot, circling the lateral side of the head of the sock wearer's Achilles tendon f17, passing above the medial malleolus f16i of the sock wearer's foot, and returning to the inferior extensor retinaculum f14. Note that the star mark Si in FIG. 7 is a mark indicating a position corresponding to the medial malleolus f16i of the sock wearer's foot, and the star mark So in FIG. 8 is a mark indicating a position corresponding to the lateral malleolus f16o of the sock wearer's foot.

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

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 finger of the sock wearer all at once, as illustrated in FIG. 1 and FIG. 2. Hereinafter, this form is referred to as the round-toe form. The toe portion 15 at the tip of the sock 1 is not limited to the round-toe form, and may be formed to cover the big toe, index finger, middle finger, ring finger, and little finger of the sock wearer separately, as illustrated in FIG. 3(a). Hereinafter, this form is referred to as the tabi form. 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 sock wearer separately, as illustrated in FIG. 3(b). Hereinafter, this form is referred to as the four-pronged form. Alternatively, the toe portion 15 at the tip of the sock 1 may be formed so as 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.

In the case of the rounded toe shape illustrated in Figures 1 and 2, the anti-slip portion 12 may include an anti-slip portion 125 for rounded toe shapes formed in a single area including 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 surface 11o and inner surface 11i of the sock bottom 11, in order to enhance the effect of the rounded toe shape described above.

In addition, in the case of the tabi form illustrated in FIG. 3(a), from the viewpoint of enhancing the effect of the tabi form described above, the anti-slip portion 12 may have an anti-slip portion 125a for tabi form 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.

In addition, in the case of the four-pronged shape illustrated in FIG. 3(b), from the viewpoint of enhancing the effect of the four-pronged shape described above, the anti-slip portion 12 may have four-pronged anti-slip portions 125b formed in four 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, and a single region including all of the regions corresponding to the pads of the ring finger and little finger.

In addition, in the case of the five-finger form illustrated in FIG. 3(c), the anti-slip portion 12 may have anti-slip portions 125c for the five-finger form formed in five areas on the outer surface 11o and inner surface 11i of the sock bottom 11, the areas corresponding to the pad of the big toe of the sock wearer, the pad of the index finger, the pad of the middle finger, the pad of the ring finger, and the pad of the little finger, from the viewpoint of enhancing the effect of the five-finger form described above.

The socks 1 having the above-mentioned design and specifications can be manufactured by appropriately combining known manufacturing methods.

(Embodiment 2)
A sock according to embodiment 2 will now be described. Note that, among the reference characters used in embodiment 2 and subsequent embodiments, the same reference characters as those used in the previous embodiments represent the same components, etc. as those in the previous embodiments, unless otherwise specified.

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 that 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 other configurations are the same as those of embodiment 1.

Although the sock 1 of embodiment 2 has a smaller effect than the sock 1 of embodiment 1, it can efficiently transmit the force of the ligaments involved in the movement of the foot when the sock wearer exercises to the ground. In addition, since the sock 1 of embodiment 2 does not have the anti-slip portion 12 on the inner surface 11i of the sock bottom surface 11, the sock manufacturability is improved compared to the sock 1 of embodiment 1. Therefore, the sock 1 of embodiment 2 can be made to be highly productive and less expensive. In addition, since the sock 1 of embodiment 2 has the anti-slip portion 12 only on the outer surface 11o of the sock bottom surface 11, it has the advantage of having better slip processing properties of the anti-slip portion 12 compared to the sock 1 of embodiment 3 described later. Other effects are the same as those of embodiment 1.

(Embodiment 3)
The sock of the third embodiment will be described.

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 that 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.

Although the sock 1 of embodiment 3 has a smaller effect than the sock 1 of embodiment 1, it can efficiently transmit the force of the ligaments involved in the movement of the foot when the sock wearer exercises to the ground. Also, since the sock 1 of embodiment 3 does not have the anti-slip portion 12 on the outer surface 11o of the sock bottom 11, the appearance of the outer surface 11o of the sock bottom 11 can be made to be the same as that of a normal sock. Other effects are the same as those of embodiment 1.

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.
