Description

Shoe body with asymmetric upper

Technical field

The present invention is a shoe body, particularly a shoe body that conforms to the foot biomechanics and has an asymmetrical upper.

Background technique

Shoes are a must-have for everyone to wear when they go out. According to the findings of existing medical research, the structure of the shoe body will affect the posture in which the person stands or walks. The shoe body structure can be roughly divided into a sole and an upper provided on the sole. When the shoemaker manufactures the shoe body, most of them only pay attention to how to improve the softness of the sole to improve the comfort when wearing the shoe. However, it is often overlooked that the design of the upper is also highly relevant to the health of the foot.

1A is a schematic view of a normal angle between a leg and a foot; FIG. 1B is a schematic view of the foot eversion of the foot; FIG. 1C is a schematic view of the inversion of the foot; FIG. 2 is a conventional shoe. Schematic diagram of the body; and FIG. 3 is a schematic view showing a state in which the foot is everted or the inversion of the sole of the foot in the conventional shoe body.

As shown in FIG. 1A, which is a schematic view of a normal angle between the leg 101 and the foot 102, one may have a situation in which the foot 102 is everted or inverted as shown in FIG. 1B or FIG. 1C due to a natural deformity. However, a poor posture for a long time may also cause the paw 102 to be everted or inverted. For example, as shown in FIG. 2, the upper 201 of the existing shoe body 200 is mostly a symmetrical design. When a person wears a shoe having a symmetrical upper 201, due to the softness and sensitivity of the instep muscles, a specific direction of motion is generated depending on the contact position of the upper 201 with the instep.

As shown in FIG. 3, since the instep has a certain curvature, when the foot 102 is touched by the instep muscles and the symmetrical upper 201, the inner side of the heel and the outer side of the forefoot are bound by the shoe body 200, thereby The heel and forefoot produce compensatory effects, causing the foot 102 to be inverted or everted. Therefore, when walking or standing, the wearer is likely to walk inside or outside the character and cause changes in the skeletal muscle system imbalance.

For example, when the wearer wears a shoe that is symmetrical to each other inside and outside of the upper 201, since the horizontal upper 201 does not conform to the curvature of the instep, the foot will naturally be on the inside of the heel A and the outside of the forefoot B and the shoe. The body 200 collides and creates a force that causes the heel to move horizontally inward and the forefoot to move horizontally outward, thereby allowing the foot to form a clockwise direction of motion (as indicated by the arrow in the figure). Assume that the heel moves horizontally inwardly, because it is restrained by the restraint of the shoe body 200 at the heel, and cannot be smoothly deflected inward, and the ankle joint can be compensated for inversion; in contrast, it is assumed that The horizontal movement of the palm to the outside is large, and it is also restrained by the shoe body 200 at the outer side of the forefoot, and the forefoot will be turned outwards to compensate and reduce the pressure on the outside of the forefoot.

Because the instep of the foot, whether it is inversion or eversion, it will have a huge impact on the body. In the long run, it will lead to unhealthy factors such as poor walking posture. Since foot movement occurs in a three-dimensional space, shoemakers need to think about how to design an upper that conforms to foot movement and foot biomechanics, and solve the problem of inversion or eversion of the foot.

The best way to achieve the invention

[First Embodiment]

As shown in FIGS. 4-6, the present embodiment is a shoe body having an asymmetrical upper including: a shoe body 10 and an upper 20.

The shoe body 10, which may be a shoe without a shoelace. The shoe body 10 has a foot tip 12 and a heel end 13 and has an opening 14 between the foot tip 12 and the heel end 13 for providing a foot extending into the shoe body 10 from the opening 14.

The upper 20 is located on the upper surface of the shoe body 10 and adjacent to the opening portion 14. For example, the shoe body 10 includes a sole (not shown) and a shoe side surface 11, the sole is a portion where the foot is stepped on, and the shoe side 11 is a portion covering the side of the foot, wherein the upper 20 is connected to the shoe side 11 And located at the part of the foot corresponding to the foot. After the upper 20 is combined with the sole and the side 11 of the shoe, the shoe body 10 can cover most of the foot, and an opening 14 is left between the side 11 of the shoe and the upper 20 for the foot to extend into the body of the shoe. Within 10.

The upper 20 has an outer edge portion 21 that is inclined from the inner side toward the outer side and the heel end 13. If a coordinate axis including the longitudinal axis 30 and the lateral axis 40 is defined on the upper 20, the end of the outer edge portion 21 near the inner side of the foot is defined as the inner end portion 211, which will be close to the outer edge of the outer edge of the foot. The end of the portion 21 is defined as an outer end portion 212, which is defined as an imaginary line extending longitudinally from the toe end 12 toward the heel end 13 and through the inner end portion 211, the transverse axis 40 being defined perpendicular to the longitudinal axis 30 and passes through the imaginary line of the inner end portion 211.

The outer edge portion 21 of the upper 20 is inclined relative to the longitudinal axis 30 and the transverse axis 40, and the outer end portion 212 of the outer edge portion 21 is closer to the heel end 13 than the inner end portion 211, more particularly , The angle between the line connecting the inner end portion 211 and the outer end portion 212 and the lateral axis 40 is between 5 degrees and 50 degrees, wherein the angle θ is preferably between 20 degrees and 30 degrees, and When the shoe body is made, if it is designed for a user with a lower arch, the angle θ will be smaller and may be as small as 5 degrees, and if it is designed for a user with a higher arch, the angle θ It will be bigger and may be as large as 50 degrees, which will produce better results.

As shown in Figures 4 through 6, the asymmetrical upper 20 can be applied to a variety of shoes without laces. As shown in FIGS. 4 and 5, the outer edge portion 21 of the upper 20 may be a convex outer edge portion. As shown in FIG. 4, the outer end portion 212 and the inner end portion 211 of the outer edge portion 21 are the intersections between the upper 20 and the shoe side 11, respectively, and as shown in FIG. 5, the upper of the convex outer edge portion. The inner and outer side ends of the 20 may also have arcuate depressions, respectively, and the outer end portion 212 and the inner end portion 211 of the outer edge portion 21 may be vertices of the arcuate depression.

As shown in FIG. 6, the outer edge portion 21 of the upper 20 may also be a concave outer edge portion, and the inner end portion 211 of the outer edge portion 21 may be a point closest to the tip end 12 of the outer edge portion 21, and The outer end portion 212 is a point at which the foot back and the outer edge portion 21 correspond to each other when the foot portion is inside the shoe body 10.

As such, when the instep of the foot contacts the inclined upper 20, the instep is blocked by the inclined upper 20 and changes the direction of movement of the foot while walking. Since the instep has a certain curvature of the instep, during the walking, the instep will first contact the outer end portion 212 of the outer edge portion 21, and the outer end portion 212 serves as a leverage lever for the lever, that is, the forefoot and the heel. The lever between the levers. When the back of the foot is stressed, the outer end portion 212 is used as a supporting lever fulcrum, and the direction of movement of the foot is changed to counterclockwise movement, so that the forefoot of the foot moves inward and the heel is outwardly displaced. The inner edge of the forefoot also just touches the inner side 11 of the shoe, thereby maintaining the ankle joint in a neutral position.

By blocking and enclosing the foot of the upper 20 and affecting the forces on the inside and outside of the foot, the ankle joint can be maintained in a neutral position. Further, the inclined upper 20 can adjust the contact position of the instep relative to the upper 20 from the inner side of the upper 20 to the outer side. When people wear shoes, the inner side of the heel is no longer restricted by the inner side 11 of the shoe, and the ankle joint is inverted. The outer side of the forefoot is no longer bound by the lateral side 11 of the shoe and cannot move, so the forefoot is not Will be everted, and can improve the problem of inversion or eversion of the heel joint and the sole of the foot.

[Second embodiment]

As shown in FIG. 7, the present embodiment is a shoe body having an asymmetrical upper including: a shoe body 10 and an upper 20.

The shoe body 10 may be a leather shoe with a shoelace, a sneaker, a casual shoe or a running shoe. The shoe body 10 has a foot tip 12 and a heel end 13 and has an opening 14 between the foot tip 12 and the heel end 13 for providing a foot extending into the shoe body 10 from the opening 14.

The upper 20 is located on the upper surface of the shoe body 10 and adjacent to the opening portion 14. In this embodiment, the upper 20 is defined to include an inner eyelet 22 and an outer eyelet 23, the inner eyelet 22 and the outer eyelet 23 each having a plurality of eyelets for the laces to pass through, wherein the inner side The first eyelet on the eyelet 22 adjacent the toe tip 12 is defined as the medial eyelet 221, and the outer eyelet blade 23 is first adjacent the tip 12 of the foot The eyelets are defined as the outer eyelets 231, and the outer eyelets 231 are closer to the heel end 13 than the medial eyelets 221.

Similarly, to facilitate the description of the asymmetrical configuration between the inner eyelet 22 and the outer eyelet 23, the self-sufficient tip 12 can be longitudinally extended toward the heel end 13 and defined by the imaginary line of the medial eye 221 as the longitudinal axis 30, An imaginary line perpendicular to the longitudinal axis 30 and through the medial eyelet 221 is defined as the transverse axis 40.

After the shoelace is attached to the inner eyelet 22 and the outer eyelet 23, a binding force from the inner side toward the outer side and the heel end 13 can be generated between the inner eye 221 and the outer eye 231, and the binding force is exerted. That is, the line connecting the inner eyelet 221 and the outer eyelet 231 overlaps, and the design between the inner eyelet 221 and the outer eyelet 231 can be made by the asymmetrical design between the inner eyelet 221 and the outer eyelet 231. The line forms an angle θ with the transverse axis 40, which in turn produces a binding force applying direction with a particular angle.

The angle θ formed between the line between the inner eye 221 and the outer eye 231 and the lateral axis 40 may be between 5 and 50 degrees, wherein the angle θ is between 20 and 30 degrees. good. In the case of a shoe body, if it is designed for a user with a lower arch, the angle θ will be smaller and may be as small as 5 degrees, and if it is designed for a user with a higher arch, the angle is θ will be larger and may be as large as 50 degrees, which will produce better results and naturally maintain the ankle joint in a neutral position.

Thereby, the user can make the back of the foot be restricted by the restraining force while walking, and the outer eye 231 acts as a lever fulcrum for the lever between the forefoot and the heel, and the forefoot and the heel The outer eyelet 231 is slightly counterclockwise moved, and then exerts an asymmetrical force on both sides of the corresponding shoe body 10, thereby adjusting the force on the inner side and the outer side of the foot corresponding to the forefoot position, and naturally making The ankle joint is maintained in a neutral position to improve the problem of inversion or eversion of the ankle joint and the sole of the foot.

[Third embodiment]

As shown in FIG. 8, the present embodiment is a shoe body having an asymmetrical upper including: a shoe body 10 and an upper 20.

The shoe body 10, which may be a slipper or a sandal, and has a foot tip 12 and a heel end 13, the foot tip 12 being the front end of the shoe body 10 and the heel end 13 being the rear end of the shoe body 10.

The upper 20 is located on the upper surface of the shoe body 10 and includes at least one fixing strap 24, and both ends of the fixing strap 24 are respectively coupled to the shoe body 10, and are located at positions corresponding to the front end of the sole of the foot, and more importantly, the fixing bundle The belt 24 is inclined from the inner side of the shoe body 10 toward the outer side of the shoe body 10 and toward the heel end 13.

The fixed strap 24 has an upper edge and a lower edge 25, the edge near the heel end 13 is the lower edge 25, and the lower edge 25 has an inner end 251 and an outer end 252. The inner end portion 251 and the outer end portion 252 are defined in accordance with the position to be connected to the shoe body 10, and the position to be connected to the inner shoe body 10 is the inner end portion 251, and the position to the outer shoe body 10 is connected. Outer end 252.

The angle θ between the line between the inner end 251 and the outer end 252 and the transverse axis 40 may be between 5 and 50 degrees such that the fixed band 24 is designed relative to the transverse axis 40 and the longitudinal axis. 30 sloping structure, the aforementioned longitudinal axis 30 can be defined as an imaginary line extending longitudinally from the toe end 12 toward the heel end 13 and through the inboard end 251, while the transverse axis 40 can be defined as perpendicular to the longitudinal axis 30 and through An imaginary line of the inner end portion 251.

By having the outer end 252 of the securing strap 24 closer to the heel end 13 than the inboard end 251, such that the lower edge 25 of the securing strap 24 and the transverse axis 40 can be sandwiched between 5 degrees The angle θ between 50 degrees, and the asymmetrical fixed strap 24 can be used to adjust the inner and outer forces of the foot. When the user walks, the curvature of the back of the foot causes the back of the foot to first contact the outer end 252 of the lower edge 25 of the fixed strap 24, and the outer end 252 acts as a lever fulcrum for the lever between the forefoot and the heel. In this way, the movement direction of the foot can be changed to the counterclockwise movement, so that the forefoot of the foot is moved inward, and the forefoot can be prevented from compensating, so as to prevent the inversion of the ankle joint and the sole of the foot or the outside. Turn the effect.

More preferably, the aforementioned angle θ can also be between 20 degrees and 30 degrees, and the angle θ will be smaller when the shoe body is made for a user with a lower arch. It may be as small as 5 degrees, and if it is designed for users with higher arches, the angle θ will be larger and may be as large as 50 degrees, which will produce better results and prevent ankle joints. Inverted or everted with the sole of the foot.

According to the description of the foregoing embodiments, it can be clearly understood that the contact angle of the instep relative to the upper 20 can be adjusted from the inner side to the outer side of the upper 20 by the inclination angle of the upper 20, thereby controlling the moving direction of the foot. When the shoes are worn, the inner side of the heel is no longer restricted by the inner sole 10, and the ankle joint is inverted. The outer side of the forefoot is no longer bound by the outer shoe body 10 and cannot move, so the forefoot is not It will be everted, so it can really reduce the inversion or eversion of the ankle when the user walks. In addition, the design of the asymmetrical upper 20 can achieve very significant results by a simple implementation, and there is indeed a gain compared to the prior art ergonomically changing design of the sole structure.
