Definitions
- the present invention relates to footwear for alleviating pain in foot caused by hallux valgus.
- Hallux valgus refers to the symptom in which the big toe is in the laterally deviated state. That is, the tip of the big toe deflects toward the small toe side, while the root portion of the big toe is bent in a “V”-shape, to project toward the medial side in the foot width direction.
- sharp pain may be caused by the root portion of the big toe being brought into contact with the insole of the shoe. This may hinder walking.

Abstract
A concave portion (31) for reducing the weight load of the wearer acting on the big toe (f1) is formed at a region in an insole (3) of a shoe (1). The region corresponds to a first site ranging from the ball (f1 a) of the big toe (f1) to the tip of the toe. Further, at a region corresponding to a second site adjacent to the heel side of the ball of the big toe (f1 a), a pressing portion (32) is formed for pressing the second site, so that the reaction force occurring by the pressing causes the first site to sink in the concave portion (31).
Description
- The present invention relates to footwear for alleviating pain in foot caused by hallux valgus.
- In recent years, an increasing number of people are suffering from hallux valgus, which is developed by continuous use of shoes not fitting to feet such as high-heeled women's shoes. Hallux valgus refers to the symptom in which the big toe is in the laterally deviated state. That is, the tip of the big toe deflects toward the small toe side, while the root portion of the big toe is bent in a “V”-shape, to project toward the medial side in the foot width direction. As the symptom of the hallux valgus progresses, sharp pain may be caused by the root portion of the big toe being brought into contact with the insole of the shoe. This may hinder walking.
- Conventionally, as footwear for alleviating such pain in the foot caused by hallux valgus, what is known is footwear in which a concave portion is formed at the insole at the position corresponding to the big toe (for example, see Patent Literature 1). The footwear is capable of reducing a weight load of a wearer acting on the big toe by the concave portion. Therefore, it can alleviate the pain in the foot while walking.
- Patent Literature 1: Japanese Examined Patent Publication No. 4-20608
- The conventional footwear can alleviate pain in the foot caused by hallux valgus. However, since the big toe itself is still in the laterally deviated state, the symptom of the hallux valgus itself cannot be improved. Further, since the lateral deviation portion of the big toe is brought into contact with the sidewall portion of the shoe, the pain in the foot cannot be fully alleviated.
- The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide footwear capable of improving the symptom of hallux valgus while fully alleviating the pain in the foot caused by hallux valgus.
- Footwear of the present invention for achieving the object stated above includes: a concave portion formed at an insole at a position corresponding to a first site ranging from a ball of a big toe to a tip of the toe for alleviating a weight load of a wearer acting on the big toe; and a pressing portion formed at the insole at a position corresponding to a second site being adjacent to a heel side of the ball of the big toe for pressing the second site, a reaction force occurring by the pressing causing the first site to sink in the concave portion.
- With the footwear of the present invention, the concave portion formed at the insole at the position corresponding to the first site ranging from the ball of the big toe to the tip of the toe can reduce the weight load of the wearer acting on the big toe. Further, the pressing portion formed at the insole presses the second site being adjacent to the heel side of the ball of the big toe. The reaction force caused by the pressing allows the first site to sink in the concave portion. Accordingly, the big toe naturally enters the medially deviated state, to approximate the original normal state from the laterally deviated state. Thus, the symptom of hallux valgus can be improved. Furthermore, since it becomes possible to suppress the big toe from being brought into contact with the sidewall portion of the shoe, the pain in the foot can be further alleviated.
- Further, it is preferable that the footwear further includes a lifting portion formed at the insole at a position corresponding to four toes except for the big toe, for lifting the four toes.
- In this case, since the four toes except for the big toe are lifted by the lifting portion, the clearance between each adjacent ones of the four toes can be widened. Thus, even in the state where the first site of the big toe sinks in the concave portion as described above, the weight of the wearer can be supported by the four toes in a stable state.
- Still further, it is preferable that the lifting portion is formed to become gradually high from a second toe toward a small toe both included in the four toes, to cause a straight line connecting top ends of the four toes to be substantially horizontal.
- In this case, since the straight line connecting the top ends of the four toes lifted by the lifting portion becomes substantially horizontal, it becomes possible to allow the weight load of the wearer to act on the four toes substantially uniformly. Thus, the weight of the wearer can be supported by the four toes in a further stable state.
- Still further, it is preferable that the lifting portion is provided with a projecting portion at the insole at a position corresponding to a clearance between a third toe and a fourth toe both included in the four toes, for widening the clearance.
- In this case, since the projecting portion widens the clearance between the third toe and the fourth toe, the weight load of the wearer can be shared by a pair of two toes, i.e., the second toe and the third toe, and another pair of toes, i.e., the fourth toe and the small toe. Thus, weight of the wearer can be supported in a further stable state.

FIG. 1 is a plan view showing a left-foot insole of footwear according to one embodiment of the present invention.FIG. 2 is a cross sectional view taken along A-A inFIG. 1 . InFIG. 1 , aninsole 3 of ashoe 1 being the footwear according to the present embodiment includes aconcave portion 31 formed at the region corresponding to the big toe f1 of the foot f, apressing portion 32 formed so as to be adjacent to theconcave portion 31, and alifting portion 33 formed at the region corresponding to the four toes f2 to f5 except for the big toe f1. Here, the “insole” refers to the element positioned at the bottom plane inside the footwear, and it includes a shoe insert placed on the bottom plane. - In planar view of
FIG. 1 , theconcave portion 31 is formed at the region corresponding to a first site ranging from the ball f1 a of the big toe f1 to the tip of the toe. As shown inFIG. 2 , the cross-sectional shape of theconcave portion 31 in the foot length direction (in the direction from the tip of toe to the heel) is formed so as to conform to the ventral side shape of the big toe f1. More specifically, in connection with theconcave portion 31, the portion corresponding to the ball f1 a of the big toe f1 is depressed the most deepest, and the portion corresponding to the ventral portion f1 b of the big toe f1 toward the tip of the toe is formed to be gradually shallower accordingly. - In planar view of
FIG. 1 , thepressing portion 32 is formed at the region corresponding to a second site adjacent to the heel side of the ball of the big toe f1 a. Thepressing portion 32 is configured to press the second site, so that the reaction force occurring by the pressing causes the first site to sink in theconcave portion 31. The pressing force to the second site is set to be greater than the force exerted by a level plane naturally pressing the second site when the foot f is placed on the level plane. - Further, such sinking of the first site is realized by using the phenomenon of the first site naturally sinking in response to the pressing, which is performed by the
pressing portion 32, acting on the tendon (abductor hallucis) connecting between the second site and the first site. The length L of thepressing portion 32 in the foot length direction is set to approximately 18 mm, and the length W in the foot width direction is set to approximately 50 mm. As shown inFIG. 2 , the cross-sectional shape of thepressing portion 32 in the foot length direction is formed as an inclined plane becoming gradually higher from theconcave portion 31 toward the heel side. -
FIG. 3 is a cross sectional view taken along B-B inFIG. 1 . As shown inFIG. 3 , thepressing portion 32 is formed to have a cross-sectional shape in the foot width direction in which the portion from the lateral side (the left side inFIG. 3 ) to the center portion is substantially, flat and the end on the medial side (the right side inFIG. 3 ) projects upward. - In planar view of
FIG. 1 , the liftingportion 33 is formed at the region ranging from the tip of each of the second toe f2, the third toe f3, the fourth toe f4 and the small toe f5, through the root portion of the four toes f2 to f5, to the peripheral portion of the root portion of the four toes f2 to f5 on the heel side. -
FIG. 4 is a cross sectional view taken along C-C inFIG. 1 . As shown inFIG. 4 , the liftingportion 33 is formed to have a cross-sectional shape in the foot length direction of an inclined plane, which becomes gradually higher from the heel side (the left side inFIG. 4 ) toward the tip (the right side inFIG. 4 ) of the four toes f2 to f5. Thus, the liftingportion 33 lifts the four toes f2 to f5. The lifting force is set to be greater than the force of a level plane naturally pressing the four toes 12 to f5 when the foot f is placed on the level plane. -
FIG. 5A is a cross sectional view taken along D-D inFIG. 1 ,FIG. 5B is a cross sectional view taken along E-E inFIG. 1 , andFIG. 5C is a cross sectional view taken along F-F inFIG. 1 . InFIGS. 5A to 5C , the cross-sectional shape of the liftingportion 33 in the foot width direction is formed as an inclined plane being continuous from theconcave portion 31, i.e., becoming gradually higher from the second toe f2 toward the small toe f5. As shown inFIG. 5A , the inclination angle of the liftingportion 33 is set such that a straight line X connecting the top ends on the dorsal side of the four toes f2 to f5 becomes substantially horizontal. -
FIG. 6 is a cross sectional view taken along G-G inFIG. 1 . As shown inFIG. 6 , in the liftingportion 33, a projectingportion 33 a is formed at the region corresponding to the clearance between the third toe f3 and the fourth toe f4. The projectingportion 33 a is configured to widen the clearance between the third toe f3 and the fourth toe f4. - With the
shoe 1 according to the present embodiment structured as described above, theinsole 3 is provided with theconcave portion 31 at the portion corresponding to the first site ranging from the ball f1 a of the big toe f1 to the tip of the toe. Therefore, the weight load of the wearer acting on the big toe f1 can be reduced, and the pain in the foot f can be alleviated. Further, thepressing portion 32 formed at theinsole 3 presses the second site adjacent to the heel side of the ball of big toe f1 a. The reaction force caused by the pressing allows the first site to sink in theconcave portion 31. Accordingly, the big toe f1 naturally enters the medially deviated state, to approximate the original normal state from the laterally deviated state. Thus, the symptom of hallux valgus can be improved. Furthermore, since it becomes possible to suppress the big toe f1 from being brought into contact with the sidewall portion of theshoe 1, the pain in the foot f can be further alleviated. - Further, since the four toes f2 to f5 except for the big toe f1 are lifted by the lifting
portion 33, the clearance between each adjacent ones of the four toes f2 to f5 can be widened. Thus, even in the state where the first site of the big toe f1 sinks in theconcave portion 31, the weight of the wearer can be supported by the four toes f2 to f5 in a stable state. - Still further, since the straight line X connecting the top ends on the dorsal side of the four toes f2 to f5 lifted by the lifting
portion 33 becomes substantially horizontal, it becomes possible to allow the weight load of the wearer to act on the four toes f2 to f5 substantially uniformly. Thus, the weight of the wearer can be supported by the four toes f2 to f5 in a further stable state. - Still further, since the projecting
portion 33 a formed at the liftingportion 33 makes it possible to widen the clearance between the third toe f3 and the fourth toe f4, the weight load of the wearer can be shared by a pair of two toes, i.e., the second toe f2 and the third toe f3, and another pair of two toes, i.e., the fourth toe f4 and the small toe f5. Thus, the weight of the wearer can be supported in a further stable state. - Note that the present invention is not limited to the embodiment described above. For example, though a shoe has been exemplarily shown as the footwear in the embodiment described above, the present invention is applicable also to footwear such as sandals, straw sandals, split-toed socks, wooden clogs or slippers.

FIGS. 7 and 8 show the result of comparison verification as to the change in hallux valgus of a foot between before and after wearing the shoe according to the embodiment described above.FIG. 7 is a drawing-substituting photograph showing the state of a foot before wearing the shoe, andFIG. 8 is a drawing-substituting photograph showing the state of the foot wearing the shoe. The shoe in the photograph is shown only by the insole, so that the foot can be easily observed. - With the foot shown in
FIG. 7 , it can be seen that the big toe is in the laterally deviated state, that is, the tip of the big toe is deflected toward the small toe, and the root portion of the big toe is bent in a “V”-shape, to project toward the medial side in the foot width direction (the left side inFIG. 7 ). - On the other hand, as compared to
FIG. 7 , the root portion of the big toe shown inFIG. 8 is suppressed from being projecting toward the medial side in the foot width direction, and it can be seen that the symptom of hallux valgus is improved. Further, it can be seen that, in connection with the four toes except for the big toe shown inFIG. 8 , the clearance between each adjacent ones of the toes is widened, as compared toFIG. 7 . In particular, it can be seen that the widened clearance between the third toe and the fourth toe is considerably wider than the clearance shown inFIG. 7 . - 1: SHOE (FOOTWEAR)

Claims (4)
1. Footwear comprising:
a concave portion formed at an insole at a position corresponding to a first site ranging from a ball of a big toe to a tip of the toe for alleviating a weight load of a wearer acting on the big toe; and
a pressing portion formed at the insole at a position corresponding to a second site being adjacent to a heel side of the ball of the big toe for pressing the second site, a reaction force occurring by the pressing causing the first site to sink in the concave portion.
2. The footwear according to claim 1 , further comprising
a lifting portion formed at the insole at a position corresponding to four toes except for the big toe, for lifting the four toes.
3. The footwear according to claim 2 , wherein
the lifting portion is formed to become gradually high from a second toe toward a small toe both included in the four toes, to cause a straight line connecting top ends of the four toes to be substantially horizontal.
4. The footwear according to claim 3 , wherein
the lifting portion is provided with a projecting portion at the insole at a position corresponding to a clearance between a third toe and a fourth toe both included in the four toes, for widening the clearance.
