Description

Shoe body with asymmetric upper

The invention is a shoe body, in particular a shoe body that conforms to the foot biomechanics and has an asymmetric upper.

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.

Figure 1A is a schematic view of the normal angle between the leg and the foot; Figure 1B is a schematic diagram of the foot valgus; the 1C is a schematic view of the foot varus; the second figure is a conventional shoe The top view of the body; and Fig. 3 is a schematic view of the condition of the foot in the conventional shoe body for the valgus of the foot or the inversion of the sole of the foot.

As shown in FIG. 1A, which is a schematic view of the normal angle between the leg portion 101 and the foot portion 102, however, one may have a situation in which the foot 102 is everted or inverted due to a natural malformation as in FIG. 1B or FIG. 1C. . However, there are also bad postures for a long time. May cause the foot 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 back of the foot has a certain curvature, when the foot 102 is touched by the muscles of the foot 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, and then The heel and the forefoot are compensated, causing the foot 102 to be inverted or everted. Therefore, when the wearer walks or stands, it is easy to walk inside the character or the outer character, and cause the imbalance of the skeletal muscle system of the whole body.

For example, when the wearer wears shoes that are symmetrical to each other inside and outside the upper 201, since the horizontal upper 201 does not conform to the curvature of the instep, the foot will naturally be on the heel side A and the forefoot side B. The shoe body 200 collides and produces 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). It is assumed 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, the forefoot is assumed. The horizontal movement 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 present invention is a shoe body having an asymmetrical upper, which has an outer edge portion which is inclined from the inner side to the outer side and the heel end direction in the upper design such that when the foot back contacts the outer end portion of the outer edge portion of the upper Naturally, the outer end is used as a fulcrum of leverage and leverages to cause the foot to compensate for movement in the counterclockwise direction and naturally maintain the ankle joint in a neutral position, thereby solving the problem of valgus or inversion of the foot.

The invention provides a shoe body having an asymmetric upper, comprising: a shoe body having a tip end and a heel end, and an opening between the tip end of the foot and the heel end for opening a foot a portion extending into the shoe body; and an upper portion on the upper surface of the shoe body and adjacent to the opening portion, the upper having an outer edge portion inclined with respect to a longitudinal axis and a lateral axis, and an outer edge portion of the outer edge portion The portion is closer to the heel end than the inner end of the outer edge portion, wherein the longitudinal axis is defined as an imaginary line extending longitudinally from the tip of the foot toward the heel end and passing through the inner end of the outer edge portion, the transverse axis being defined as perpendicular to The longitudinal axis passes through an imaginary line of the inner end of the outer edge portion.

The invention further provides a shoe body having an asymmetric upper, comprising: a shoe body having a foot tip and a heel end, and having an opening between the tip end of the foot and the heel end for one foot The opening protrudes into the shoe body, and the shoe body has a shoelace; and an upper is located on the upper surface of the shoe body and adjacent to the opening, the upper includes an inner eyelet and an outer eyelet, and the inner shoe The eye piece and the outer eye piece respectively have a plurality of eyelets for the shoelace to pass through, wherein the first eyelet on the inner eyelet piece near the tip of the foot is defined as an inner eyelet, and the outer eyelet piece is first near the tip of the foot The eyelets are defined as an outer eyelet and the outer eyelet is closer to the heel end than the medial eyelet.

[First Embodiment]

As shown in FIGS. 4 to 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 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 which is inclined from the inner side toward the outer side and the heel end 13. If defined on the upper 20, including the longitudinal axis 30 and the transverse direction To the coordinate axis of the axis 40, the end of the outer edge portion 21 near the inner side of the foot is defined as the inner end portion 211, and the end portion of the outer edge portion 21 near the outer side of the foot is defined as the outer end portion 212, the longitudinal axis 30 The definition is that the self-contained tip 12 extends longitudinally toward the heel end 13 and passes through the imaginary line of the inboard end 211, which is defined as an imaginary line perpendicular to the longitudinal axis 30 and through the inboard end 211.

The outer edge portion 21 of the upper 20 is inclined with respect to the longitudinal axis 30 and the lateral 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, and the angle θ is preferably between 20 degrees and 30 degrees. 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 θ will be more Large, 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 shoelaces. 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 convex outer edge portion The inner and outer side ends of the upper 20 may also have arcuate recesses, 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 recess.

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 the point closest to the tip end 12 of the outer edge portion 21. The outer end portion 212 is a point at which the foot back contacts the outer edge portion 21 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.

The ankle joint can be maintained 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. 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 also It does not turn outwards, but it can improve the problem of inversion or eversion of the heel joints and soles.

[Second embodiment]

As shown in FIG. 7, the embodiment is a shoe body having an asymmetric upper, comprising: 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 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 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 first insole on the medial eyelet 22 adjacent the tip 12 of the foot is defined as an inner eyelet 221, and the first insole on the lateral eyelet 23 adjacent the tip 12 of the foot is defined as an outer eyelet 231, and The outer eyelet 231 is closer to the heel end 13 than the inner eyelet 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 connection between the inner eyelet 221 and the outer eyelet 231 overlaps, and the connection between the inner eyelet 221 and the outer eyelet 231 can be made by the asymmetric design between the inner eyelet 221 and the outer eyelet 231. An angle θ is formed with the transverse axis 40 to generate a binding force applying direction having a special angle.

The angle θ formed between the line connecting the inner eyelet 221 and the outer eyelet 231 and the lateral axis 40 may be between 5 and 50 degrees, and preferably the angle θ is between 20 and 30 degrees. 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 θ It 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 foot of the foot be restricted by the restraining force while walking, and the outer eye 231 as the forefoot and heel lever The lever fulcrum is used, and the forefoot and the heel are slightly counterclockwisely moved by the outer eyelet 231, thereby applying an asymmetrical force on both sides of the corresponding shoe body 10, thereby adjusting the position corresponding to the forefoot. The forces on the medial and lateral sides of the foot and naturally maintain the ankle joint 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, 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 two ends of the fixing strap 24 are respectively connected 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 adjacent 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. That is, the outer end portion 252.

The angle θ between the line between the inner end 251 and the outer end 252 and a 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 to prevent the inversion or eversion of the ankle joint and the sole of the foot. The effect.

More preferably, the aforementioned angle θ can also be between 20 degrees and 30 degrees, and the angle θ will be smaller and possibly smaller when designing the shoe body for a user with a lower arch. Up to 5 degrees, and if 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 the ankle joint and the sole of the foot. Inverted or everted.

According to the description of the foregoing embodiments, it is clearly understood that the angle of inclination through the upper 20 can adjust the contact position of the foot back relative to the upper 20 from the inner side to the outer side of the upper 20, thereby controlling the direction of movement 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 be moved, so the forefoot is also It does not turn outwards, so it can really reduce the phenomenon of 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 has its gain compared to the prior art ergonomically changing design of the sole structure.

The embodiments are described to illustrate the features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the present invention and to implement the present invention without limiting the scope of the present invention. Equivalent modifications or modifications made by the spirit of the disclosure should still be included in the scope of the claims described below.
