Technical Field
[0001] The utility model relates to the field of shoes, in particular to a shoe structure capable of adjusting a midfoot activity space, and a shoe comprising the shoe structure capable of adjusting a midfoot activity space. Background Art
[0002] Basketball is a comprehensive sport, mainly divided into running, jumping, and a lot of sudden stops and vertical movements, so athletes have more stringent requirements for the functionality of basketball shoes. The wrapping and support of the middle arch of the foot has always been one of the important indicators to measure the functionality of basketball shoes. It is also an important structure to reduce sports injuries and improve sports performance.
[0003] The arch of the foot, also known as the plantar fascia, is a ligament in the human body that connects the heel bone to the base of the toes. The design of the arch of basketball shoes has the following important significance for basketball:
[0004] 1. Support and stability: The arch of the foot is one of the most important supporting structures of the foot. In basketball games, athletes need to frequently change direction, turn, jump and other movements. The stability of the arch of the foot directly affects the athlete's stability and the accuracy of the movement.
[0005] 2. Comfort and adaptability: The space design of the arch area affects the comfort and wearing experience of basketball shoes. Appropriate space design can effectively reduce the pressure and friction of the arch area, reduce foot fatigue and discomfort, and improve the wearing experience of athletes. Preventing sports injuries: The space design of the arch area is also closely related to preventing sports injuries. Appropriate space design can reduce sprains, wear and friction of the foot, and reduce the risk of athletes getting injured during competitions.
[0006] At present, there are not many sports shoes designed for midfoot protection by domestic and foreign sports brands. Most of them are midfoot restraints achieved by the convexity of the midsole and the coordinated pulling of the upper. Although this structure is convenient to use, it cannot accurately give pressure to the arch of the midfoot when pulling, and it only provides more support to the inner side of the midfoot. Utility Model Content

[0028] In order to better understand the purpose, structure and function of the present invention, the shoe structure with adjustable midfoot activity space of the present invention is described in detail below with reference to the accompanying drawings.
[0029] like Figure 1As shown, the shoe structure with adjustable midfoot activity space includes a first adjustment unit 100 and a second adjustment unit 200 that are connected in sequence, and the side of the sole body close to the inner side of the human foot is defined as the inner side of the sole body, and the side of the sole body close to the outer side of the human foot is defined as the outer side of the sole body. The first adjustment unit 100 corresponds to the position of the arch of the human midfoot, and the second adjustment unit 200 corresponds to the inner side, the instep, and the outer side of the midfoot of the human midfoot, that is, it is arranged in the form of partitions surrounding the human midfoot from the arch position to the outer side of the midfoot. By adjusting the tightness of the structure, the second adjustment unit 200 and the first adjustment unit 100 apply pressure to the midfoot arch position from the upper side and the lower side respectively, thereby tightening the arch, increasing the height of the activity space between the arch and the sole, and achieving the effect of expanding the activity space of the midfoot.
[0030] The human arch of the foot is a convex upward arch structure composed of the tarsal bones, metatarsal bones, joints, ligaments and tendons of the foot. It can be divided into the medial longitudinal arch and lateral longitudinal arch pointing from the toe to the heel, and the transverse arch pointing from the inside to the outside. Among them, the medial longitudinal arch has greater elasticity and plays a role in buffering shocks, so it is also called the elastic arch of the foot. When the human body is walking, running and jumping, the elasticity of the arch of the foot can properly withstand the force of standing, walking and jumping, and effectively reduce the impact of the ground on the body, protecting the internal organs, especially the brain from shocks.
[0031] Based on the above-mentioned structure and elastic characteristics of the human arch, the first adjustment unit 100 of the shoe structure with adjustable midfoot activity space is elastically deformable to provide uniform wrapping pressure to the midfoot arch when tightened, thereby ensuring that pressure is applied to the arch while maintaining the elasticity of the arch itself. When the wearer applies downward pressure to the midfoot area, based on the elasticity of the arch itself and the elastic deformation of the first adjustment unit 100, the midfoot arch is forced to move toward the sole, thereby reducing the midfoot activity space. After absorbing the pressure, the arch returns to its original shape to release energy, causing the arch to move away from the sole again, and then the midfoot activity space is increased again, and so on and so forth, so that the wrapping pressure of the midfoot can be freely adjusted in the shoe cavity, thereby achieving the effect of adjustable midfoot activity space.
[0032] Preferably, the first adjustment unit 100 is a special multi-directional stretch fabric material to evenly apply pressure on the special-shaped plane formed by the medial longitudinal arch, the lateral longitudinal arch, and the transverse arch, so that the first adjustment unit 100 can fully fit the human arch in three dimensions and adapt to the arches of different foot shapes.
[0033] In order to better understand the purpose, structure and function of the present invention, the shoe structure and shoe with adjustable midfoot activity space of the present invention are further described in detail below with reference to the accompanying drawings, taking the specific structure of the shoe structure with adjustable midfoot activity space as an example.
[0034] Embodiment 1, as Figure 1 As shown, the shoe structure with adjustable midfoot activity space includes a first adjustment unit 100 and a second adjustment unit 200 which are connected in sequence. The first adjustment unit 100 corresponds to the position of the arch of the midfoot of a human body, and includes a first end 101 and a second end 102, and a first connecting section 103 between the first end 101 and the second end 102. The first end 101 is connected to the outer side of the midfoot of the shoe, specifically the connection between the upper and the sole, so that the first adjustment unit 100 is arranged in the shoe cavity, which better fits the shape of the arch when tightened, and has a better effect of wrapping the arch.
[0035] The second adjustment unit 200 includes a first connection part 210 and a second connection part 220. The first connection part 210 is detachably connected to the outer side of the midfoot upper. The second connection part 220 corresponds to the inner side and the instep of the midfoot of the human body. The first connection part 210 is connected to the second end 102 of the first adjustment unit 100 through the second connection part 220. As a preferred embodiment, the first adjustment unit 100 adopts an elastic band. Of course, it can also be other elastic structures, that is, as long as it can achieve elastic binding pressure on the midfoot arch, thereby forming an overall structure of the shoe structure that can adjust the midfoot activity space. By wrapping the midfoot arch in a zoned manner, the first adjustment unit 100 applies pressure to the arch without losing the original elasticity of the arch body, so that the wrapping pressure of the midfoot can be freely adjusted in the shoe cavity, thereby achieving the effect of adjustable midfoot activity space. In addition, the elastic band increases the pressure on the bottom of the arch without squeezing the foot, which also improves the comfort of the sole.
[0036] Specifically, the first end 101 of the first adjustment unit 100 is fixedly arranged at the junction of the surface and bottom of the outer side of the midfoot of the shoe. The connection method can be stitching, gluing or hot melting. This position is used as the anchor point of the shoe structure with adjustable midfoot activity space. The first adjustment unit 100 is extended to the inner side of the midfoot, and then connected to the second connection part 220 so that it extends upward along the inner lining of the inner side of the shoe upper. Preferably, the second connection part 220 adopts a non-elastic fabric strap, which is connected to the first adjustment unit 100 to jointly wrap the sole of the foot, and limit the deformation of the inner side of the midfoot and the instep, so as to provide stable support for this area.
[0037] The first connecting portion 210 can be detachably connected to the outer side upper of the midfoot by Velcro, buttons, perforated laces or knob lace systems, etc. Preferably, a BOA knob buckle can be used to provide a stronger fixing tension and increase convenience.
[0038] like Figure 2As shown, the first connection part 210 includes a fifth end 211 and a sixth end 212, and a third connection section between the fifth end 211 and the sixth end 212; the second connection part 220 includes a third end 221 and a fourth end 222, and a second connection section between the third end 221 and the fourth end 222. The third end 221 of the second connection part 220 is connected to the second end 102 of the first adjustment unit 100, and the fifth end 211 of the first connection part 210 is connected to the fourth end 222 of the second connection part 220 through a movable connection assembly 230, and the movable connection assembly 230 can provide dynamic tension between the first connection part 210 and the second connection part 220 to fit different instep heights and angles.
[0039] Preferably, the movable connection component 230 is a movable rope, one end of which is connected to the fourth end 222 of the second connection part 220, and the other end is inserted from the inside of the outer upper and out of the outside of the outer upper, and is fixed to the outer upper through the fifth end 211 of the first connection part 210. Of course, the movable connection component 230 can also adopt other movable band structures, that is, as long as it can achieve the effect of dynamically tightening the first connection part 210 and the second connection part 220 to fit different insteps.
[0040] Furthermore, the device also includes an adjustment component 240, which protrudes outward from the inner shoe upper and is connected to the second connection part 220. By moving the adjustment component 240 up and down, the second connection part 220 is moved up and down along the inner side of the midfoot, thereby changing the length of the first adjustment unit 100, thereby adjusting the tightness of the first adjustment unit 100, so as to efficiently control the first adjustment unit 100 to provide suitable pressure, suitable wrapping and arch pressure to the wearer's midfoot, wherein high-pressure wrapping can improve the explosive power, running speed and dynamic stability of the lower limbs in the front and back directions, medium-pressure wrapping can improve muscle coordination ability, and low-pressure wrapping can improve knee joint stability and single-foot standing balance ability during the emergency stop and take-off buffering stage.
[0041] Preferably, the adjustment component 240 adopts a buckle, which includes two connecting ends and a lifting portion bent between the two connecting ends. The two connecting ends are connected to the outer surface of the second connecting section in sequence along the direction from the toe to the heel, so that the lifting portion protrudes from the inner upper, forming an annular structure on the outer surface of the second connecting section. When the foot enters the shoe cavity, the wearer can insert only one finger into the buckle to adjust it up and down according to personal preferences and needs, thereby quickly adjusting the position of the second connecting part 220, and then adjusting the tightness of the first adjustment unit 100, thereby improving the utilization efficiency of the shoe structure with adjustable midfoot activity space.
[0042] Of course, the adjustment component 240 may also be in the form of a rod, a plate, a rope, or the like, as long as it can achieve the effect of quickly adjusting the position of the second connection portion 220 .
[0043] When in use, first loosen or separate the connection between the first connecting part 210 and the upper, and the specific operation varies depending on the fixing method adopted. Then put the foot into the shoe cavity, and then pull the buckle by hand to adjust the wrapping pressure of the structure on the midfoot. After adjusting to the appropriate pressure, fix the first connecting part 210 to the upper.
[0044] The partitioned wraparound structure of the shoe structure with adjustable midfoot activity space is to wrap the midfoot, and there is no restriction on the connection of the structure. Therefore, other embodiments different from the first embodiment are proposed for the technical feature of the connection of the structure, which are as follows:
[0045] In the second embodiment, the first end 101 of the first adjustment unit 100 is connected to the outer side of the middle section of the insole to achieve the effect of wrapping the midfoot.
[0046] In the third embodiment, an extension structure is provided at the middle part of the tongue, and the first adjustment unit 100 and the second adjustment unit 200 are formed by extending the middle part of the tongue.

[0049] In the sixth embodiment, both the first adjusting unit 100 and the second adjusting unit 200 adopt a dynamic rope threading structure.
[0050] In the seventh embodiment, the shoelace structure is extended to the fixing point of the first end 101 of the first adjusting unit 100 to form the first adjusting unit 100 and the second adjusting unit 200 .
