[0033] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] like Figures 1 to 6As shown, the utility model discloses an arch support sock, comprising: a sock body 100, on which an elastic connecting belt, a first fixing portion 110 and a second fixing portion 120 are provided. The first fixing portion 110 is provided at a position of the sock body 100 corresponding to the human foot close to the forefoot, and the second fixing portion 120 is provided at a position of the sock body 100 corresponding to the human heel. The elastic connecting belt is provided at the bottom of the sock body 100 and connects the first fixing portion 110 and the second fixing portion 120. The positions of the first fixing portion 110 and the second fixing portion 120 relative to the human foot remain unchanged.

[0036] The sock body 100 is a five-finger sock. The first fixing part 110 includes a finger ring 111 and a connecting part 112. A finger ring 111 is provided on each toe of the sock body 100. The connecting part 112 is connected to the finger ring 111. The connecting part 112 is set at a position of the sock body 100 close to the forefoot and is set around the sock body 100.

[0037] In this embodiment, the first fixing portion 110 is configured in the style of a five-finger sock, so that the first fixing portion 110 is difficult to move relative to the human foot, thereby maintaining the distance between the first fixing portion 110 and the second fixing portion 120 unchanged, allowing the elastic connecting band to perform its function.

[0038] In order to avoid relative displacement between the second fixing part 120 and the human foot, the second fixing part 120 is wrapped around the outside of the human heel, and an ankle fixing strap 150 is provided on the side of the sock body 100 close to the ankle. The ankle fixing strap 150 is provided at a position close to the ankle of the sock body 100 and surrounds the sock body 100, and the end of the ankle fixing strap 150 is connected to the second fixing part 120.

[0039] In this embodiment, the resistance of the second fixing portion 120 wrapping around the human heel alone may not be enough to counteract the tension generated by the elastic connecting band. Therefore, an ankle fixing band 150 is required to assist in securing the second fixing portion 120 and prevent it from moving toward the toes. In the above embodiment, to improve the wearing comfort of the sock body 100, the first fixing portion 110 and the second fixing portion 120 are both integrally provided with the sock body 100. Furthermore, the ankle fixing band 150 is composed of multiple second elastic cords, which are woven together with the sock body 100. The use of fine elastic material in a linear pattern woven together with the fabric of the sock body ensures heat and moisture dissipation from the sock body while enhancing the wrapping force of this portion of the sock body, thus evenly dissipating the tension of the elastic band.

[0040] In this embodiment, the elastic connecting belt imitates the ligaments of the human body, and the function of the elastic connecting belt is the same as that of the plantar ligaments of the human body, which is to support the longitudinal arch of the foot. Figure 6As shown, the triangular structure of the internal and external longitudinal arches of the human foot is mainly composed of the calcaneus, talus, navicular bone, cuboid bone, medial cuneiform bone, first metatarsal bone, fifth metatarsal bone, and ligaments, which are assembled in sequence. The top of the arch structure is the talus and cuboid bone, and the two sides are the calcaneus and the first metatarsal bone and the fifth metatarsal bone. The bottom side is composed of ligaments. One end of the plantar ligament is connected to the side of the calcaneus and the other end is connected to the side of the metatarsal bone. The two ends of the plantar ligament that maintains the stability of the bottom layer of the triangular structure of the longitudinal arch are attached to the heel and the metatarsophalangeal joint and toes respectively. In order to make the function of the elastic connecting band more similar to that of human ligaments, the connecting portion 112 extends to the metatarsophalangeal joint of the foot, so that one end of the elastic connecting band is connected to the connecting portion 112.

[0041] The elastic connecting band can be separate from the sock body 100, fixedly connected, or integrally woven. In this embodiment, the elastic connecting band can be separate from the sock body 100, bonded to the sock body 100, printed onto the sock body 100 using 3D printing technology, or integrally woven with the sock body 100. In this embodiment, the elastic connecting band is separated from the sock body 100, which is more conducive to protecting the transverse arch of the foot.

[0042] The elastic connecting band is detachably connected to the first fixing portion 110 and the second fixing portion 120, and the elastic connecting band is detachable or detachably connected to the sock body 100. In this embodiment, different elastic connecting bands can be used for people with different body shapes or different arch conditions, thereby increasing the product's specificity and improving the support effect for different arches.

[0043] The elastic connecting belt is composed of a plurality of first connecting belts 131 . One end of the first connecting belt 131 is connected to the first fixing portion 110 , and the other end is connected to the second fixing portion 120 .

[0044] In this embodiment, since the sock body 100 is a five-finger sock, five first connecting straps 131 are provided, and each first connecting strap 131 is connected to a finger ring 111. This arrangement can disperse the tension of the elastic connecting strap, making the tension distribution of the elastic connecting strap more reasonable and increasing the comfort when wearing.

[0045] One end of the second connecting belt 132 is connected to the side of the first fixing part 110, and the other end is connected to the second fixing part 120 at the bottom of the sock body 100. The second connecting belt 132 gradually turns from the side of the first fixing part 110 to the bottom of the sock body 100. The second connecting belt 132 is separated from the sock body 100 between the human heel and the metatarsophalangeal joint.

[0046] In this embodiment, the provision of the second connecting strap 132 further optimizes the tension structure, making the first connecting strap 131 and the second connecting strap 132 more similar to the effect of human ligaments, providing better support for the transverse arch of the foot and better wearing comfort. In the above embodiment, the first connecting strap 131 and the second connecting strap 132 are both elastic straps and are flat, which can reduce the foreign body sensation on the sole of the foot and improve wearing comfort. At the same time, the elastic connecting straps are provided with colors, and the tension of elastic connecting straps of different colors is different. The strength of the elastic straps with different tension levels suitable for people of different weights can be adjusted by changing the width and distinguished by color matching.

[0047] In this embodiment, ligaments are relatively weak compared to bone structures. Excessive pressure during high-intensity exercise or standing can repeatedly stretch the plantar ligaments, causing ligament relaxation and, in turn, arch collapse. The tension generated by the deformation of the first and second connecting straps 131 and 132 helps the plantar ligaments maintain the relative position of the calcaneus and metatarsals, stabilizing the triangular structure and reducing pressure on the plantar ligaments.

[0048] Support for the transverse arch of the foot is achieved by providing an arch reinforcement 140 on the sock body 100 at the arch of the foot. The arch reinforcement 140 is a strap that wraps around the sock body 100. The arch reinforcement 140 is composed of multiple first elastic cords that are woven into one piece with the sock body 100.

[0049] In this embodiment, the transverse arch of the human foot is mainly composed of the forefoot formed by the five metatarsal bones, and the midfoot formed by the medial, middle, and lateral cuneiform bones and the cuboid bone. The apexes of the forefoot and middle transverse arches are the second metatarsal bone and the middle cuneiform bone, respectively. The ligaments that maintain the transverse arch mainly include the dorsal metatarsal ligament, the dorsal tarsometatarsal ligament, and the plantar metatarsal ligament. By adding a first elastic rope to the forefoot (near the toe side) and midfoot area and weaving it together with the sock body 100, stronger support is provided to maintain the structural stability of the transverse arch.

[0050] In this embodiment, the transverse arch reinforcement portion is made of fine elastic material in a linear shape and woven together with the fabric of the sock body, thereby ensuring heat and moisture dissipation of the sock body while enhancing the wrapping force of this part of the sock body.

[0051] The bottom of the sock body 100 is provided with anti-slip bumps.

[0052] In this embodiment, the provision of the anti-slip protrusions can improve the anti-slip performance of the socks.

[0053] In the above-described embodiment, the starting and ending points of the longitudinal arch support elastic band are located at the heel and at the metatarsophalangeal joint and toes, identical to the plantar ligaments that maintain stability at the bottom layer of the longitudinal arch's triangular structure. The plantar ligament's starting and ending points are attached to the bones of the triangular structure, effectively maintaining arch stability in conjunction with the foot muscles. When muscles fatigue or ligament laxity occurs, the bottom edge passively stretches beyond a certain limit, causing the triangular structure to lose stability and lead to arch collapse. At this point, the elastic band on the sole of the foot generates tension through deformation, securing the bony structures on both sides, alleviating the pressure of stretched plantar ligaments and stabilizing the longitudinal arch triangular structure. Furthermore, the elastic band at the heel distributes the tension through the first fixing portion 110 of the five-finger sock body, ensuring comfort and fixing the direction of the tension, making it difficult to dislocate and maintaining support in the correct direction. The transverse arch support elastic band is reinforced by the annular arch reinforcement portion 140 at the forefoot and midfoot, providing effective protection.

[0054] In summary, the tension created by this specially designed elastic connecting strap can adaptively support the arch of the foot as the intensity of exercise changes, without squeezing the sole of the foot. It also provides no pressure and significantly inhibits arch drop, meeting the public's demand for comfortable and safe arch support.

[0055] Example 2

[0056] The difference between this embodiment and the first embodiment is that the first fixing portion 110 covers the sock body 100 corresponding to the position from the toe to the metatarsophalangeal joint of the human body.

[0057] In this embodiment, the first fixing portion 110 covers the sock body 100 from the toe to the metatarsophalangeal joint. Even if the first fixing portion 110 is pulled by the elastic connecting band, it will not be displaced from the human foot. The sock body 100 can be any type of sock, not limited to five-toed socks.

[0058] Example 3

[0059] This embodiment differs from the first embodiment in that the first elastic cord is flat and fixedly connected to the inside or outside of the sock body 100, or is integrally provided with the sock body 100. The second elastic cord is flat and fixedly connected to the inside or outside of the sock body 100, or is integrally provided with the sock body 100. The drawstring is flat and provided on the inside or outside of the sock body 100, or is integrally provided with the sock body 100.

[0060] In this embodiment, the first elastic cord, the second elastic cord and the drawstring can be arranged on the inner side or the outer side of the sock body 100 or integrated with the sock body 100 to achieve their corresponding functions.

[0061] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
