Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe in which a user can easily insert his / her foot and walk easily.

[0002]

2. Description of the Related Art Generally, for shoes, such as athletic shoes, in which the ease of walking after inserting a foot, that is, the holdability of the foot is taken into consideration, a wearing mouth or the like for inserting a user's foot is required. It tends to be formed relatively small. That is, when the shoes are made relatively small, the shoes are hard to come off, and it is easy for the shoes to hold their feet. On the other hand, in shoes that allow other people to wear shoes, such as shoes for infants, unlike the above-mentioned sports shoes, it is easier for other people to wear due to the holding property after inserting the foot, so the mouthpiece etc. are compared. Tend to be formed large. In this case, the user can easily insert his / her foot, but unlike the athletic shoes, since the foot does not hold well, the foot is not sufficiently fixed in the shoe and the shoe is hard to walk.

[0003]

However, in recent years, there has been a strong demand for shoes which, unlike conventional ones, have good holding properties, are easy to walk on, and have large openings and the like for easy insertion of feet. But,
As described above, pursuing the holdability makes the shoe difficult to wear, and pursuing the ease of inserting the foot with a large opening, the holdability is poor and the shoe becomes difficult to walk.
Further, if both the high holdability and the size of the mouth, etc. are required, the shoe becomes halfway, which makes it difficult to walk and difficult to insert a foot, which is a further problem.

In view of the above points, it is an object of the present invention to provide a shoe which is easy to put on and easy to put on, and which is capable of fixing the inserted foot sufficiently. And

[0005]

According to the first aspect of the present invention, there is provided a wear opening for inserting a user's foot, and a part of the wear opening is cut away to provide a toe side direction. An upper main body portion including a foot insertion opening formed toward the front, a tongue-shaped contact portion arranged corresponding to the formation of the foot insertion opening, and the foot insertion opening portion. A fixing belt portion for holding the opening state in an arbitrary state, and at least one end portion of the fixing belt portion is detachably attached to the upper body portion, and a position adjustable engaging means is inserted. A sole for arranging the sole side of the user's foot, a sole on the sole formed on the sole to hold the heel of the inserted foot, and an upper formed on the upper body. The rigidity of the body side heel part and at least the upper body side heel part And a counter portion arranged to wear the shoe, wherein both end portions of the fixing belt portion are arranged close to an outer edge portion of the counter portion and both ends of the fixing belt portion. When a virtual line connecting the substantially central portions of the respective parts in the width direction is extended as it is, this virtual line is formed in the rear end region of the shoe by the heel portion on the upper body side and the heel portion on the sole side. The fixing belt portion is provided so as to reach the boundary portion or the vicinity thereof, and further, the fixing belt portion can be arranged at a foot height point on the instep of the user or in the vicinity thereof. Is achieved by a shoe characterized by:

According to the structure of claim 1, when the virtual line connecting the substantially central portions in the width direction of both ends of the fixing belt portion is extended as it is, the virtual line is the rearmost end region of the shoe. The fixing belt portion is provided so as to reach the boundary portion formed by the heel portion on the upper body side and the heel portion on the shoe sole side or in the vicinity thereof. Therefore, the fixing belt portion acts to fix the user's foot in the direction of the heel of the shoe. Therefore, as compared with the case where the user's foot is fixed in the shoe sole direction like a conventional shoe, the holding property is significantly improved, the foot moves in the shoe, and it is difficult to walk, It can prevent the movement of the foot and the influence on the shape of the foot.

Further, according to the present invention, at least the heel portion on the upper body side is provided with a counter portion arranged to increase its rigidity. Therefore, by arranging the counter part, the rigidity of the heel part of the upper body side of the shoe is enhanced, and the counter part is used for the heel part of the shoe formed by the heel part of the upper body side and the heel part of the shoe sole side. The heel of the person's foot can be easily held accurately. That is, when the fixing belt portion acts to fix the user's foot in the heel portion direction of the shoe as described above, the heel of the user's foot is moved through the counter portion having the increased rigidity. Since the heel of the foot is pressed against the heel of the shoe and the heel of the foot is more firmly fixed to the heel of the shoe, the holding property is significantly improved.

According to the present invention, both end portions of the fixing belt portion are arranged close to the outer edge portion of the counter portion. Therefore, since the counter portion and the both end portions are not directly fixed and can be deformed according to the deformation of the foot of the user when walking, the user can easily deform the foot when walking. The shoes are easy to walk. As a result, the user's foot is firmly fixed in the shoe, and since it is easy to bend as necessary, the shoe is easy to walk.

Further, according to the present invention, the fixing belt portion can be arranged at or near the foot height point of the user's foot. Therefore, it is possible to effectively prevent the fixing belt portion from pressing the upper of the user's foot toward the sole of the shoe and lowering the holdability of the foot in the shoe. That is, when the fixing belt portion is arranged on the instep of the toe side from the foot high point of the user's foot or in the vicinity thereof, the pressing force of this fixing belt portion is from the instep side to the sole side of the foot. It is turned and tries to fix the foot by pushing the foot to the sole side. With this, by simply pressing the instep of the foot, the movement of the foot in the shoe is likely to be large, and the foot is easily displaced,
The heel of the foot cannot be fixed, making it difficult to walk. In this respect, in the configuration of the present invention, since the fixing belt portion is arranged at or near the foot height point of the user's foot, the instep of the foot is not unnecessarily pressed against the sole side of the shoe, The heel of the foot is fixed in the direction of the heel, preventing the foot from moving in the shoe.

Further, in the structure of the present invention, a foot insertion opening formed by cutting out a part of the shoe opening portion toward the toe side direction, and a foot insertion opening corresponding to the foot insertion opening. A tongue-shaped abutment arranged. Therefore, if the foot insertion opening is widened and the tongue-shaped contact portion is opened, the shoe opening of the shoe is opened sufficiently large,
The shoe is easy for the user to put in.

Further, in the structure of the present invention, a fixing belt portion for holding the opening state of the foot inserting opening portion in an arbitrary state, and at least one end portion of the fixing belt portion includes the upper body portion. And an engaging means that can be attached and detached to and whose position is adjustable. Therefore, since the fixing of the foot is done only by attaching and detaching the fixing belt to the upper body, it can be attached and detached much more easily than when fixing it with a string or the like, and the position can be adjusted, so that the size and shape of the foot are different. Corresponding to, can be fixed. As described above, according to the structure of the present claim, the shoe is easy for the user to put in or easy for the helper to wear, and after wearing the shoe, the foot is pressed against the heel of the shoe and fixed. Therefore, the shoes are easy to walk with good hold.

FIG. 7 is a schematic bottom view of the infant shoe 100 of FIG. Figure 1
The infant in the walking period wearing the infant shoes 100 shown in is an infant of, for example, 8 months to 12 months, and the walking mode is to "grab and stand" by grasping on a desk or the like and using the power of the hand. While moving laterally. And, at the time of this "grabbing and standing", there is a feature that the user stands on the tip of the toe or tries to walk with the tip of the toe standing.

By the way, as shown in FIGS. 2 and 7, the infant shoe 100 is a shoe which is an inner surface on which the sole side of the foot of an inserted infant or the like is arranged and a portion which actually contacts the ground or the like. It has a sole 120 that is the bottom. This sole 120
As shown in FIG. 7, the non-slip portion 12 has, for example, a circular shape.
1 is formed in large numbers. By forming a large number of circular anti-slip portions 121 on the surface of the shoe sole 120 in this way,
An infant wearing the infant shoes 100 can walk without slipping. Also, this shoe sole 1
20 is made of a material that is soft enough to follow the movements of the foot of a baby about 8 months old when the walking phase begins, such as polyester, cotton, nylon,
It is made of canvas (canvas), tricot, synthetic rubber, etc.

As shown in FIG. 2 and the like, an upper 110, which is an upper main body, is formed on the upper portion of the shoe sole 120 so as to wrap the foot of an infant or the like. This upper 1
10 is made of a soft material in its entirety so as not to hinder the bending of the ankles, toes, etc., which are carried out during the walking of infants during the walking period, and the surface is made of mesh-processed polyester or the like. By doing so, breathability is particularly ensured. As shown in FIG. 1 and the like, the upper 110 is provided with a shoe opening 111 for inserting a foot of an infant or the like.
Are formed. Then, a part of the shoe opening 111 is cut out to form a foot insertion opening 112 in a substantially U shape toward the toe side direction, and this opening is formed so as to be connected to the opening of the shoe opening 111. .

A tongue piece 113, which is a tongue-shaped contact portion, is arranged in the foot insertion opening 112 so as to close the opening, as shown in FIG. The tongue piece 113 is formed of polyester whose surface is meshed, and the inside of the tongue piece 113 is made of a highly flexible material such as polyester. The toe-side end of the tongue piece 113 is a tongue-like contact portion attachment region provided at or near the toe-side end of the foot insertion opening 112 of the upper 110 shown in FIG. It is fixed to the stitched portion 114 by, for example, stitching.

Therefore, the tongue piece 113 is the suture portion 1 of FIG.
14 is curved with a fixed end and the tongue piece 113 is attached to the infant shoe 10
It can be tilted to the toe side of 0, whereby the foot insertion opening 112 can be opened, and the tongue piece 113 may be an obstacle when a user such as an infant inserts a foot. Absent. In FIG. 8, the tongue 113 is opened to the toe side, and
FIG. 3 is a schematic plan view showing a state in which the foot insertion opening 112 is opened.

When the opening formed by the shoe opening 111 and the foot insertion opening 112 is shown in FIG. 8 which is a plan view, L1 in FIG. 8 is formed to be, for example, about 70 mm to 80 mm. This is 55% or more of the total length (L2) since the total length (L2) of FIG. 8 is 120 mm to 140 mm when the infant shoe 100 in FIG. 8 is shown in the plan view of FIG. It is possible to form a large opening of 55% to 75%.

By the way, as shown in FIG. 1, infant shoes 1
The fixing belt portion 130 for maintaining the opening state of the foot insertion opening portion 112 of No. 00 in any state.
It is located in. The fixing belt portion 130 is a tongue piece 1.
Similar to 13, the surface is made of mesh-processed polyester or the like, and the inner side is made of a flexible material such as polyester, so that it is easily deformable. The outer periphery 130a of the fixing belt portion 130 shown in FIG. 1 is piped with cotton or the like to prevent deformation such as extension in the length direction. Also,
The fixing belt portion 130 has a left end portion (inner foot side) 1
31 is fixed to the upper 110 as a fixed end as shown in FIGS. FIG. 9 is a schematic perspective view showing a state in which the fixing belt portion 130 of FIG. 1 is opened. As shown in FIG. 9, the fixing belt portion 130 includes the wearing port 111.
It is formed in an arcuate shape so as to be concave to the side, and as described later, the fixing belt portion 130 is configured to fix the foot height point of the foot of an infant or the like or the vicinity thereof. Therefore, the fixing belt portion 130 is configured so as not to hit the foot of the infant or the like when the infant or the like wears the infant shoe 100 and walks.

At the right end portion (outer foot side) 132 which is the other end portion, a surface fastener 132a which is a detachable engaging means is formed. The corresponding surface fastener 133a is also formed on the surface of the upper 110 corresponding to the surface fastener 132a.

Therefore, by adjusting the engaging position of the surface fastener 132a provided at the right end portion 132 of the fixing belt portion 130 and the surface fastener 133a provided at the upper 110, the foot insertion of the infant shoe 100 is performed. The opening of the use opening 112 can be held in an arbitrary state. In addition, normally, the surface fastener 132a of the right end portion 132 is replaced with the surface fastener 1 of the upper 110.
When attached to 33a, both ends 131 and 132 are arranged at positions symmetrical with respect to the longitudinal direction, which is the longitudinal direction of the shoe. Therefore, it is possible to reduce the distortion of the entire infant shoe 100 caused by a large tightening amount of the fixing belt portion 130, and to apply the fixing belt portion 130 evenly to the left and right. Therefore, the heel portion 11 of the infant shoe 100 is applied with proper force in the heel direction from the high point side of the foot of an infant or the like to be described later.
5 can be securely fixed. Therefore, the shoes are easy for infants to walk or practice walking.

Further, since the fixing of the right end portion 132 of the fixing belt portion 130 is only the attachment / detachment of the surface fasteners 132a and 133a, the attachment / detachment can be performed extremely easily as compared with the case of fixing with a cord or the like. Therefore, after an infant or the like puts his / her foot on the shoe, the foot can be easily and firmly fixed to the shoe, and it is a shoe that is easy for a caregiver such as a mother to wear.

By the way, the infant shoe 100 shown in FIG. 1 is provided with a heel portion 115 in which the heel of the foot of the inserted infant is placed. This heel portion 115 is specifically shown in FIG.
As shown in (a), a shoe sole heel portion 122 which is a shoe sole heel portion formed on the shoe sole 120 and an upper body heel portion 116 which is an upper body side heel portion formed on the upper 110 are provided. Have Since the upper heel part 116 of the heel part 115 is formed as a part of the upper part 110 described above, the heel part 115 has insufficient rigidity,
Unable to hold the heels of the feet of the user, such as the infant, to a suitable degree. Therefore, as shown in FIG. 4A, the counter portion 140 is arranged inside the upper heel portion 116 to increase the rigidity of the upper heel portion 116.

The counter section 140 is specifically
As shown in FIG. 4A, the side surface has a substantially fan shape, and is formed of rubber or the like having a thickness of, for example, about 1.2 mm. By arranging the counter part 140 inside the upper heel part 116, the rigidity of the upper heel part 116 is improved and the rigidity of the entire heel 115 shown in FIG. 4A is improved. Then, the heel of the foot of an infant or the like is accurately held on the heel portion 115 having improved rigidity.

As described above, the counter portion 140 is disposed inside the upper side heel portion 116 of the infant shoe 100. As shown in FIG. 4A, the counter portion 140 is located close to the outer edge portion 141 of the counter portion 140. The left end portion 131 of the fixing belt portion 130 is arranged at. The right end portion 132 has the same structure. In this way, the both end portions 13 of the fixing belt portion 130 are opposed to the counter portion 140 of the infant shoe 100.
1, 132 are not directly fixed. Therefore, deformation such as forward bending of the ankle due to walking is absorbed by deformation of the upper 110 made of a flexible material arranged between the outer edge portion 141 and both end portions 131 and 132 of the fixing belt portion 130. . This makes it possible to absorb the deformation of the infant shoes 100 caused by the deformation of the legs of an infant or the like when walking, and to walk the infant shoes 100 without imposing an unnecessary burden on the infant.
Has become.

That is, on the contrary, when both ends of the fixing belt portion 130 are directly fixed to the counter portion 140, the rigidity of the counter portion 140 is high, so that the infant shoes caused by the deformation of the ankle during walking. The child's shoes cannot absorb the deformation of 100 and hinder the deformation of the ankles, which makes it difficult for an infant to walk.

By the way, FIG. 4 (a) (b) and FIG.
Surface fastener 1 at the right end 131 of the fixing belt portion 130
32a shows the arrangement state of the fixing belt portion 130 when the user walks by engaging the surface fastener 133a of the upper 110. At this time, a virtual line A is a virtual line connecting the substantially central portions of the left end portion 131 of the fixing belt portion 130 shown in FIG. 4A in the width direction. If this virtual line A is extended as it is, this virtual line A will be
The fixing belt portion 130 is arranged so as to reach the boundary portion A ′ between the upper heel portion 116 and the sole heel portion 122 on the right end side of the shoe in FIG. It At this time, the imaginary line A is extended, and the angle θ at a portion intersecting with the imaginary line D of the placement surface (floor) shown in FIG. 4A is, for example, 30 degrees to 40 degrees.

That is, as described above, the fixing belt portion 13 is
When the both end portions 131 and 132 of 0 are arranged, the infant or the like who is the user wears the infant shoe 100, and the fixing belt portion 13
When fixing the foot at 0, the fixing belt portion 130 is
As indicated by the phantom line A in (a), it acts to fix the foot in the shoe toward the heel portion 115 of the shoe. When the foot is fixed toward the heel portion 115 of the shoe in this way, compared to the conventional case where the foot is fixed toward the shoe sole,
The holding property of the foot is remarkably improved. In particular, since the foot is fixed at the heel portion 115 where the position of the foot easily shifts during walking, it is possible to prevent the foot from slipping in the infant shoe 100 due to walking. Further, since the counter portion 140 for increasing the rigidity is arranged on the upper side heel portion 116 of the heel portion 115 of the shoe as described above, the foot is pressed toward the heel portion 115 by the fixing belt portion 130. Then, since the heel of the foot is more firmly fixed to the heel 115 of the shoe due to the existence of the counter portion 140, the holding property of the foot is significantly improved.

At this time, as shown in FIG.
The outer edge portion 141 of the counter portion 140 and the fixing belt portion 1
Since both end portions 131 of 30 are arranged close to each other, the rigidity of the counter portion 140 can be effectively used. That is, when the foot is pressed in the heel direction by the fixing belt part 130, the heel of the foot can be fixed to the heel part 115 of the shoe while making maximum use of the rigidity of the counter part 140.

Next, the lower edge portion 134 side of the fixing belt portion 130 in FIGS. 4 (a) and 5 is arranged at or near the high point of the instep of the infant or the like. . The foot high point of this foot or its vicinity is specifically shown in FIG.
Is a point indicated by an arrow B. FIG. 10 is a schematic explanatory diagram of the skeleton of the foot of a person. In this way, the fixing belt portion 13
When the lower edge portion 134 side of 0 is arranged at the foot high point B portion of the instep of the infant, the fixing belt portion 130 fixes from the foot high point B toward the heel point. . For this reason, the fixing belt portion 130 attaches the instep of the infant to the sole 120.
By pressing in the direction, it is possible to effectively prevent the holding property of the foot in the infant shoe 100 from being deteriorated.

That is, when the fixing belt portion 130 is arranged on the instep of the toe side from the foot high point B of the infant's foot or in the vicinity thereof, the pressing force of the fixing belt portion 130 is the foot. It is directed from the instep side to the sole side of the foot and presses the foot against the sole 120 side to fix the foot. With this, the baby shoes 100
The movement of the foot in the inside tends to be large, the foot is easily displaced, the heel of the foot cannot be fixed, and it becomes difficult to walk.
That is, even when the foot is sufficiently fixed, the foot is unlikely to bend and the foot shoe 100 is likely to be displaced in the shoe. Also, when the fixing belt portion 130 is arranged on the ankle side, the position of the foot in the shoe may be displaced, or the fixing belt portion 130 may hit the ankle during walking and hinder the movement. In this respect, according to the infant shoe 100 of the present embodiment,
Since the lower edge portion 134 side of the fixing belt portion 130 is arranged at the foot height point B of the infant's foot, the instep of the foot is not unnecessarily pressed against the sole side. In particular, the fixing belt portion 130
However, since it can be effectively prevented from being arranged on the instep of the toe side from the foot height point B, the foot of the infant can be more accurately positioned.
Infant shoes 10 that can be pressed against the heel portion 115 of 00 to further improve the holdability of the infant's foot and not hinder walking.
It becomes 0.

By the way, FIG. 11 is a schematic perspective view showing a state in which an infant is wearing the infant shoe 100 according to the present embodiment, and the heel of the foot is lifted for walking or standing on the toes, which is often seen at this time. FIG. 12 is a schematic sectional view of the infant shoe 100 of FIG. 11. FIG. 13 is a schematic explanatory view showing a toe flexion line of a person's foot. As shown in FIG. 12, when an infant wears the infant shoes 100 and moves the heel of the foot to float, the portion of the toe called the toe bending line is bent. Specifically, as shown in FIG. 13, the toes from the thumb side to the little finger are called first to fifth toes, respectively. Then, each first to fifth toe is provided with a middle toe joint as shown in FIG. What is used for bending the foot is a toe bending line C shown by an arrow C in FIG. 13, and this toe bending line C is arranged substantially at or near the metatarsal joint.

Further, since the bending motion of the foot which bends along the toe bending line C is an important motion during walking, the toe bending line C is particularly important in shoes for infants who cannot walk well. It is important that the shoe is flexible along the. In the present embodiment, the suture portion 114 shown in FIG. 1 is formed at a position corresponding to or above the toe bending line C of the infant who is the user or the vicinity thereof. As described above, the suture portion 114 is provided on the toe-side end of the foot insertion opening 112 or on the upper 110 near the end. Then, in the sewn portion 114, the toe end of the tongue piece 130 of FIG. 1 is attached to the upper 110 by stitching or the like to form the above-mentioned fixed end.

Since the stitched portion 114 as described above is sewn or the like, it becomes a weaker portion than the surrounding upper 110. At the same time, the fragile portion is located above the toe bending line C of the infant's foot. Therefore, since the sutured portion 114 of FIG. 1 corresponds to above the toe bending line C of the foot of an infant or the like, when the infant bends the foot along the toe bending line C, the sutured portion 114 will Bend along the finger bend line C. An insole 400 is arranged inside the shoe sole 120 as shown in FIG. This insole 4
A flexion groove 401 serving as a fragile portion is formed at a position on the shoe sole side corresponding to the toe flexion line C of 00 or the vicinity thereof. FIG. 14A is a schematic bottom view of the insole 400, and FIG. 14B is a schematic sectional view taken along the line EE ′ of FIG. As shown in FIG. 14 (a), the bending groove 401 has a curved shape that bulges toward the toe side, and the bending groove 401 in FIG. 14 (b) also bends the foot of the infant along the toe bending line C. In this case, as in the case of the suture portion 114, the bending is performed along the toe bending line C. For this reason, the shoe is easy to walk, and can easily follow the bending of the foot.

By the way, the fixing belt portion 13 shown in FIG.
The width of the portion arranged on the tongue piece 113 of 0 is formed to be about 20 mm to 25 mm. That is, when the width of this portion is more than 25 mm, the width is too wide to accommodate the difference in size and shape of the infant's foot, and the positional deviation of the fixing belt portion 130 is likely to occur. The fixing belt portion 130 cannot follow the unevenness,
As a result, the fixing of the foot by the fixing belt portion 130 becomes insufficient, and the foot easily shifts in the infant shoe 100.

On the other hand, when the width of the above portion is less than 20 mm, not only is it easy to bite into the foot, but also the bending movement of the foot of the infant causes the fixing belt portion 130 to be twisted and fixed to the infant's foot. This is because the relative position of the fixing belt portion 130 changes and it becomes difficult to firmly fix the foot with the fixing belt portion 130. Therefore,
If the width of the portion of the fixing belt portion 130 arranged on the tongue 113 is formed to be about 20 mm to 25 mm, the fixing belt portion 13 can be fixed without slipping the foot in the shoe.
Excellent fixing belt part 1 that can firmly fix your feet at 0
It will be 30.

By the way, FIG. 15 is a schematic sectional view showing the shape of the toe portion of the upper 110 of the infant shoe 100 of the present embodiment. As shown in FIG. 15, the inside of the toe part of the upper 110 of the infant shoe 100 is formed such that the portion where the big toe of the infant is placed is thickest and the portion where the little finger is placed is gradually thinned. ing. That is, the vertical gap between the inside of the toe of the upper 110 and the thumb is formed to be larger than the gap between the other toes and the inside of the toe.

As described above, the most gap between the thumb and the toe portion is formed. The toe portion inhibits the dorsiflexion of the thumb even when the infant bends the thumb while walking. This is because it does not. For this reason, since the infant can keep his balance when walking, his / her thumb can be dorsiflexed inside the infant shoe 100, so that the child can smoothly practice walking. In addition, a gap portion is formed on the outside of the little finger inside the toe portion of the upper 110 so as not to prevent the finger from being opened, and it is particularly easy to open the little finger in order for the infant to maintain balance when walking. In addition to the above-described configuration, as shown in FIG.
A counter loop 142 is formed in the vicinity of.

The infant shoe 100 according to the present embodiment is constructed as described above, and its usage and the like will be described below. Here, an example will be described in which a mother, who is a caregiver, causes an infant, who is a child, to wear the infant shoes 100.

The engagement of the surface fasteners 132a and 133a is released.
Then, grasp the upper end of the tongue piece 113 of FIG.
The other end, which is a free end, is opened to the toe side of the shoe with the fixed end on the side of the suture portion 114 of 3 as the center. This state is shown in FIG.
Is. As shown in FIG. 8, the length (L1) of the opening formed by the shoe opening 111 and the foot insertion opening 112 is 1
As compared with the total length (L2) of 00, it reaches about 60%, so that a large opening can be formed.

Further, since such a large opening is formed, the infant shoe 100 in which the mother can easily insert the infant's foot, that is, the infant's shoe 100 can be easily worn. Next, contrary to the above, the mother returns the tongue piece 113 to the state shown in FIG. 9, and from there, the surface fastener 132a of the right end portion 132 of the fixing belt portion 130.
Is engaged with the surface fastener 133a of the upper 110,
Fix it. Therefore, unlike the case where the mother or the like is fixed with a string or the like, the mother or the like can easily let the infant wear the infant shoes 100. At this time, both end portions 1 of the fixing belt portion 130
As described above, the reference numerals 31 and 132 are arranged in symmetrical positions. Therefore, the fixing belt portion 1
By tightening 30 too much, the foot 100 can be securely fixed to the shoe without the infant shoe 100 being distorted. Further, since the fixing belt portion 130 does not press the instep of the infant's instep toward the sole of the shoe but fixes it by pushing toward the heel, the foot is fixed inside the shoe without disturbing walking. Therefore, the infant shoe 100 is easy to walk and has high holdability. Even when the mother or the like takes off the infant shoe 100,
Similarly, since the opening can be enlarged, the shoe can be easily removed.
