Description

  The present invention relates to a shoe that allows a user to easily insert a foot and walk easily.

For example, in the case of an infant who is still unfamiliar with walking, shoes can be easily attached and detached, and at the same time, it is difficult to walk if the infant's feet cannot be securely held in the shoes. For this reason, a belt structure or the like that is easy to attach and detach and holds the infant's foot securely in the shoe has been proposed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).
JP 2003-339408 A (FIG. 1 etc.) JP 2000-116409 A (FIG. 1 etc.) Japanese Patent Laying-Open No. 2005-118470 (drawings, etc.)

However, infants and the like wearing shoes as shown in Patent Document 1 have relatively thick ankles and it is difficult to fit them on their feet. In fact, they can take off or wear shoes without removing the belt. Often done. In this case, when the shoe belt holds the foot securely, the infant has a problem that it is difficult to put on and take off the shoe.
On the other hand, in order to make it easier for infants to put on and take off their shoes, if the belt is loosened with respect to the foot, the belt will not hold the foot securely, so the infant's foot will move unnecessarily in the shoe and will be difficult to walk This causes a problem that the proper structure for walking cannot be exhibited.
In this way, with conventional shoes, there is no problem when a mother or other caregiver puts it on, but when an infant or the like wears it off, the foot hold is satisfied while satisfying the requirements of ease of putting on and taking off shoes. There is a problem that it is difficult to ensure the sex at the same time.

  Then, it aims at providing the shoes which can ensure the holdability of a foot | seat at the same time satisfy | filling the requirements of the ease of putting on and taking off of shoes.

According to the first aspect of the present invention, there is provided a shoe sole portion for arranging a sole side of a user's foot, and an upper body formed so as to stand up from the shoe sole portion and wrap the user's foot. And a heel part for arranging a heel of a user's foot, wherein the upper main body part has a mouth part for inserting the user's foot, and the foot part. A foot insertion opening formed in a toe side direction by cutting away a part of the tongue, a tongue-like contact portion disposed corresponding to the foot insertion opening, and the tongue-like contact portion And a fixing belt portion disposed with respect to the foot insertion opening, and at least the heel portion is provided with a counter portion for increasing the rigidity thereof, and the fixing belt portion includes the tongue Formed integrally with the abutting portion and protrudes outward from its side edge The fixing belt portion and the corresponding upper main body portion are formed with an engaging portion for fixing the fixing belt portion to the upper main body portion, and the engaging portion is fixed to the fixing main belt portion. The position of the belt part for the upper body part can be changed, and the end part of the fixing belt part is arranged close to the counter part, and the end part of the fixing belt part The fixing belt portion is provided such that an extended portion of an imaginary line passing through a substantially central portion in the width direction reaches the heel portion or the vicinity thereof, and a foot height point on the instep of the user is the imaginary line. The fixing belt portion is arranged so as to be correspondingly positioned, and at least the fixing belt portion expands and contracts along the imaginary line arrangement direction in the fixing belt portion. The elastic part is arranged Are, the tongue-shaped contact portion, said elastic guide portion for telescoping portion is stretchable in the arrangement direction of the virtual line is formed, the tongue abutment, the foot insertion opening side A contact layer disposed on the outer surface and a protective layer disposed on the outside, the stretchable portion is sewn so as to be integrated with the contact layer and the protective layer, and the stretchable guide portion is The shoe is formed by stitching the contact layer and the protective layer .

According to the configuration of the first aspect, the extension portion of the imaginary line passing through the substantially central portion in the width direction of the end portion of the fixing belt portion is fixed to the heel portion or the vicinity thereof and to be disposed at the foot height point. A belt portion is provided.
Therefore, the tongue-like contact portion acts to correctly hold the user's foot toward the heel portion of the shoe via the fixing belt portion. For this reason, as compared with the case where the user's foot is fixed only in the shoe sole direction as in conventional shoes, the foot can be fixed much more reliably, and the holdability is improved. That is, in this invention, since a leg | foot can be fixed toward a heel direction, it becomes the structure which a leg | foot is hard to slip | deviate in shoes and is easy to walk. For this reason, it is possible to prevent adverse effects on foot travel and foot shape.

According to the present invention, at least the collar portion is provided with a counter portion arranged to increase its rigidity, and the fixing belt portion is held in the vicinity of the counter portion.
Therefore, by arranging the counter part, the rigidity of the heel part of the shoe is increased, and the heel of the user's foot is accurately fixed to the heel part of the shoe and is easily held.
That is, when the tongue-shaped contact portion and the fixing belt portion act so as to fix the user's foot toward the heel portion of the shoe as described above, the user's foot is interposed via the counter portion with increased rigidity. Since the heel of the shoe is held in the direction of the heel of the shoe and the belt is fixed in the vicinity of the counter, the foot heel is held with a little play so that it goes more appropriately toward the heel of the shoe. As a result, the holdability is remarkably improved.
Further, since the rigidity of the counter portion is high, it is possible to prevent the heel portion from being deformed when the shoe is worn, so that the shoe can be easily attached and detached.

Further, in the configuration of the present claim, a foot insertion opening formed by cutting away a part of the wearing mouth portion toward the toe side direction, and a tongue disposed corresponding to the foot insertion opening And an abutting portion.
Therefore, if the opening for inserting the foot is widened and the tongue-like contact portion is in the open state, the shoe mouth portion opens sufficiently wide, and the shoe is easy for the user to put in and take off. In addition, the shoe is easy for the user's caregiver to wear and take off.

  In addition, the fixing belt portion is integrally formed so as to protrude to the side edge side of the tongue-like contact portion, and the relative position with respect to the upper main body portion can be adjusted by the engaging portion. Since the relative position between the tongue-shaped contact portion and the upper body portion can be changed by simply attaching and detaching the handle, not only can the opening for foot insertion be easily exposed, but also the contact strength of the tongue-shaped contact portion against the foot Can be easily adjusted.

According to the present invention, the fixing belt portion is provided with an expansion / contraction portion for extending / contracting at least the fixing belt portion in the arrangement direction of the virtual line. For this reason, even if the fixing belt portion is securely holding the user's foot, the user or the user's caregiver extends the stretchable portion in the direction of pulling the tongue-like contact portion with the foot or hand. Thus, the shoes can be easily taken off or taken off.
Conversely, wear user shoes, or even if the user of the intervention aid's causes wearing shoes, without loosening or removing the fixing belt portion from the upper body portion, i.e., the fixing belt foot If the stretchable part is extended so that the tongue-like contact part is lifted upward with a foot or a hand while it is securely fixed and held, shoes can be worn.
And since this expansion-contraction part expands-contracts in the arrangement | positioning direction of a virtual line, ie, a hip part direction, the belt part for fixing | fixed parts can hold | maintain a leg to a hip part direction in use.

In this way, for example, an infant whose ankle is relatively thick and difficult to fit into shoes can put on and take off shoes without removing the fixing belt portion, and such shoes can be attached and detached. However, since the fixing portion belt portion and the tongue-like contact portion always hold the foot in a state where it is easy to walk reliably, that is, in a fitted state, the shoe becomes easy to walk. In addition, it is easy for infants and other parents to easily put their shoes on and remove them.
Further, in the present invention, the tongue-like contact portion is formed with an expansion / contraction guide portion for expanding / contracting the expansion / contraction portion in the arrangement direction of the virtual line. For this reason, even when the expansion / contraction part is extended by the user's operation, it is possible to prevent the fixing belt part from expanding / contracting in a direction different from the direction of the imaginary line.
For this reason, even when an infant or the like detaches shoes violently, the fixing belt portion and the tongue-shaped contact portion are always in contact with the foot by arranging the engaging portion of the fixing belt portion at an appropriate position. It fits properly and is placed in a holding position, so that it is easy for the user to walk.
As described above, according to the present invention, it is possible to provide a shoe that satisfies the requirements of ease of putting on and taking off a shoe and at the same time secures the holdability of the foot.
Moreover, according to the said structure, an expansion-contraction guide part and an expansion-contraction part can be comprised reliably and easily, providing the protective layer protected from the outside and the contact layer which fits a leg | foot.

The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

(About the outline of the overall configuration of the infant shoe 100 according to the embodiment of the present invention.)
FIG. 1 is a schematic perspective view showing an infant shoe 100 according to an embodiment of the present invention.
An infant shoe 100 as shown in FIG. 1 is a shoe for an infant of about 1 year 6 months to 2 years 6 months, for example. At this time, infants begin to become better at walking, and not only stop running on their own, but also want to wear their own shoes.

As shown in FIG. 1, the infant shoe 100 has a shoe sole portion 110 for placing a sole of a foot of an infant who is a user, for example. Further, infant shoe 100, to rise from the sole portion 110, and toddler upper body portion 120 which is formed to surround the foot and, with a heel portion 1 30 for placing the infant's foot heel Yes.
Further, the upper main body portion 120 of the infant shoe 100 has a wear mouth portion 140 and a tongue-like contact portion 150 for inserting an infant's foot. The tongue contact portion 150 will be described later.

FIG. 2 is a schematic plan view showing a state where the tongue-like contact portion 150 of FIG. 1 is opened on the toe side of the infant shoe 100.
As shown in FIG. 2, the footwear opening 100 is formed in the infant shoe 100 by cutting away a part of the mouthpiece 140 and forming toward the toe side.
Therefore, as shown in FIG. 2, when the foot insertion opening 160 is widened and the tongue-like contact portion 150 is opened, the wearing mouth portion 140 of the infant shoe 100 opens sufficiently wide, and the infant opens his / her foot. The shoe is easy to put in and take off. In addition, it is easy for children to wear their shoes, and it is easy for them to remove their shoes.

As shown in FIGS. 1 and 2, the tongue-like contact portion 150 corresponds to the foot insertion opening 160 and is disposed so as to cover the foot insertion opening 160. It is fixed to the upper main body 120 on the side.
As shown in FIGS. 1 and 2, the infant shoe 100 includes, for example, a belt portion 170 that is a fixing belt portion disposed with respect to the tongue-like contact portion 150 and the foot insertion opening 160. Yes. The configuration of the belt unit 170 will be described later.
As shown in FIG. 1, the infant shoe 100 is provided with at least a counter portion 131 for increasing its rigidity, as shown in FIG. 1.
Specifically, the hatched portion in FIG. 1 is the counter portion 131 and is formed inside the collar portion 130. The counter unit 131 is made of, for example, rubber or nonwoven fabric having a thickness of about 1.2 mm.

(About belt part 170 etc.)
As shown in FIGS. 1 and 2, the belt portion 170 is formed integrally with the tongue-like contact portion 150. Further, the belt portion 170 is disposed so as to protrude from both sides of the tongue-like contact portion 150.
Specifically, an inner foot side belt portion 171 that is the inner foot side of the infant shoe 100 and an outer foot side belt portion 172 that is the outer foot side are arranged.
As shown in FIG. 2, for example, female side fasteners 173 and 173, which are engaging portions, are provided on the inner surface side (the side in contact with the upper main body portion 120) of the inner foot side belt portion 171 and the outer foot side belt portion 172. Each of them is formed (a portion indicated by hatching in FIG. 2), and the foot insertion opening 160 can be exposed largely.
In addition, the upper main body 120 corresponding to the inner foot side belt portion 171 and the outer foot side belt portion 172 includes, for example, two male side fasteners 121 that are engaging portions on the upper main body portion side, for example. (The portion indicated by diagonal lines in FIG. 2).
The belt 170 is fixed to the upper main body 120 by the female side fastener 173 and the male side fastener 121 on the upper main body 120 side engaging each other on the belt 170 side.

Since the female side fastener 173 on the belt portion 170 side is arranged in a wide range in the extending direction of the belt portion 170 as shown by the hatched portion in FIG. 2, the male side fastener 121 of the upper main body portion 120 and by adjusting the engagement position, and has a modifiable configuration the position of the belt unit 170 with respect to the upper body section 1 2 0.
Specifically, the engagement position between the female side fastener 173 of the inner foot side belt portion 171 and the male side fastener 121 of the upper main body portion 120 is deepened or shallowed, The relative position with respect to the upper main body 120 is changed.
Similarly, the outer foot side belt portion 172 can also make the engagement position between the upper main body portion 120 and the male side surface fastener 121 deeper or shallower. These inner foot side belt portion 171 and the outer foot side belt portion 172 can be made shallower. The portion 172 is configured to be able to independently and independently change the position of the upper main body 120 according to the difference in the shape of the foot.

In this way, the relative position between the tongue-like contact portion 150 and the upper main body portion 120 can be adjusted only by attaching and detaching the belt portion 170, so that the contact strength of the tongue-like contact portion 150 with the infant's foot is increased. Can be easily adjusted.
Further, by adjusting the inner foot side belt portion 171 and the outer foot side belt portion 172 of the infant shoe 100 separately and independently, it is always possible to adjust to the foot regardless of the shape of the foot or the size of the foot. On the other hand, the inner foot side belt portion 171 and the like can be arranged at an appropriate position and can be held by the tongue-like contact portion 150.

As described above, in the present embodiment, the belt portion 170 and the upper main body portion 120 are engaged with the hook-and-loop fasteners 173 and 121 so that the position of the belt portion 170 with respect to the upper main body portion 120 can be changed.
Therefore, the foot can be fixed and released only by attaching and detaching the hook-and-loop fasteners 173 and 121, and can be operated very easily as compared with the case where the foot is fixed by a string or the like.
In addition, as an engaging part, you may employ | adopt not only a hook-and-loop fastener but other engaging means, such as a hook.
As described above, since the position of the belt part 170 with respect to the upper main body part 120 can be easily adjusted, the infant's foot can be easily attached without distorting the infant shoe 100 corresponding to the difference in the size or shape of the infant's foot. It can be fixed to the infant shoe 100.

By the way, as shown in FIG. 1, the end portion of the outer leg side belt portion 172 is disposed close to the heel portion 130. That is, it is disposed in the vicinity of the counter unit 131 in the collar unit 130. The same applies to the inner foot side belt portion 171.
That is, the engaging part 121 on the upper body part side is arranged at a position close to the counter part 131.
Therefore, since the outer leg side belt part 172 and the inner leg side belt part 171 hold the tongue-like contact part 150 in a state where the outer leg side belt part 171 is disposed near the counter part 131 of the heel part 130, the belt part 170 and the upper part 120 The infant's foot can be securely fixed and held.
On the other hand, as shown in FIG. 1, since the flange portion 130 and the belt portion 170 are not directly fixed, the rigidity between them is lower than that of the counter portion 131.
By being configured in this manner, the space between the heel portion 130 and the belt portion 170 can be slightly deformed according to the deformation of the foot when the infant walks, and the foot is easily deformed and walks easily when the infant walks. Infant shoes 100 are provided.

Further, the belt portion 170 is arranged so that an extended portion of the imaginary line V passing through the substantially central portion in the width direction of the belt portion 170 reaches the flange portion 130 or the vicinity thereof.
Specifically, as shown in FIG. 1, the extended portion of the imaginary line V at the end portion of the outer foot side belt portion 172 reaches the heel portion 130, and in the present embodiment, near the boundary with the shoe sole portion 110. positioned.
With this configuration, the tongue-like contact portion 150 acts to fix the infant's foot toward the heel portion 130 via the belt portion 170. For this reason, as compared with the case where the foot of the infant is fixed only in the shoe sole direction as in the case of conventional infant shoes, the foot is fixed much more reliably, and the holdability is improved.
That is, in the present embodiment, since the infant's foot can be fixed toward the heel part 130, the infant's foot 100 has a structure in which the foot is difficult to move and is easy to walk. The infant shoe 100 can prevent the adverse effect on the shape.

Further, as described above, the collar portion 130 is provided with the counter portion 131 in order to increase its rigidity (see FIG. 1). Therefore, by arranging the counter part 131, the rigidity of the heel part 130 of the infant shoe 100 is increased, and the heel part of the infant's foot is accurately fixed to the heel part 130 and is easily held.
That is, when the tongue-like contact portion 160 and the belt portion 170 act so as to fix the infant's foot in the direction of the heel portion 130 of the infant shoe 100, the infant's foot is supported via the counter portion 131 having increased rigidity. Since the heel is held toward the heel portion 130 of the infant shoe 100 and the foot heel is more securely fixed to the heel portion 130 of the infant shoe 100, the holdability is remarkably improved.
In addition, since the rigidity of the counter portion 131 is high, it is possible to prevent the heel portion 130 from being deformed when the infant shoe 100 is worn, so that the child can easily attach and detach the shoe.
As described above, the infant shoe 100 of the present embodiment is a shoe that is easy to walk because the infant's foot is firmly fixed in the infant shoe 100 and is also easily bent when necessary.

FIG. 3 is a schematic explanatory view of a human foot skeleton and the like viewed from the side. As shown in FIG. 3, a person's foot has a portion called a foot height point B at a portion indicated by an arrow B.
And in the infant shoes 100 of the present embodiment, the belt portion 170 is arranged so that the foot height point B of the instep of the infant is located corresponding to the virtual line V in FIG. ing.
Therefore, the belt part 170 presses the back of the infant's foot toward the shoe bottom part 110, and the infant's heel is not fixed, the foot in the infant shoe 100 is not fixed, and the holdability is lowered. Can be effectively prevented.

That is, when the imaginary line V of the belt portion 170 is arranged on the instep side of the toe side from the foot height point B of the instep of the infant, the pressing force of the belt portion 170 is applied from the instep side to the back side of the foot. It tries to fix the foot by pressing the foot only on the sole side.
In this case, just by pressing the part of the instep, the heel of the foot moves in the infant shoe 100 and it becomes difficult to walk.
On the contrary, if the above-mentioned virtual line V is arranged from the foot height point B toward the infant's ankle, the movement of bending the infant's ankle is prevented this time.

  In this regard, in the present embodiment, the belt portion 170 is arranged so that the foot height point B on the instep of the infant is positioned corresponding to the virtual line V. For this reason, the belt portion 170 does not unnecessarily press the instep of the foot against the sole side, and the movement of the ankle is not hindered. In addition, since the heel of the foot is fixed toward the heel portion 130 of the infant shoe 100, it is possible to prevent the foot from moving in the infant shoe 100.

Incidentally, as shown in FIG. 2, the belt portion 170 is provided with an expansion / contraction portion 174 for expanding and contracting the inner foot side belt portion 171 and the outer foot side belt portion 172 along the arrangement direction of the virtual line V in FIG. 1. Has been. The stretchable part 174 is made of, for example, rubber.
Specifically, as shown in FIG. 2, in the present embodiment, the stretchable portion 174 is also a connecting portion that connects the inner foot side belt portion 171 and the outer foot side belt portion 172.
However, it is not necessary for all of the connecting portions to be the stretchable portions 174 as described above, and a part of the connecting portions may be the stretchable portions.

In the present embodiment, since the expansion / contraction part 174 is disposed, even when the belt part 170 securely holds the infant's foot (for example, the state of FIG. 1), the infant takes off himself / herself. By applying a force to pull out the foot from the mouth portion 140, the stretchable portion 174 slightly extends, the tongue-like contact portion 150 moves obliquely upward, and the mouth portion 140 slightly expands, so that the infant shoes 100 can be easily expanded. Can be taken off.
Conversely, even when the infant wears the infant shoes 100 by himself / herself, the expansion / contraction part can be applied by applying a force to insert the foot into the mouth part 140 without loosing or removing the belt part 170 from the upper body part 120. 174 extends slightly and the tongue-like contact portion 150 moves obliquely upward, and the mouthpiece portion 140 slightly expands, so that the infant shoe 100 can be easily put on.

In addition, the extension / contraction part 174 extends and contracts in the direction of the virtual line V, that is, in the direction of the buttock 130 as shown in FIG. It can be fixed in the 130 direction.
In this way, the infant can put on and take off the infant shoes 100 without removing the belt part 170, and even if such an infant shoe 100 is attached or detached, the belt part 170 and the tongue-shaped contact can be removed. Since the contact part 150 always fixes and holds the infant's foot in a state where it is easy to walk reliably, the contact part 150 becomes a shoe that is easy to walk. Further, it is easy for children such as infants and the like who operate and remove the belt portion 170 to easily put on and remove shoes.

Further, in the present embodiment, the stretchable part 174 is fixed to the tongue-like contact part 150. Specifically, as shown in FIG. 2, the center of the stretchable portion 174 is stitched so across the width direction of the stretchable portion 174 in FIG, stretchable portion sewn portion 17 5 is formed.
Thus, by sewing at the center of the expansion / contraction part 174, an infant or the like can expand and contract the outer foot side belt part 172 and the inner foot side belt part 171 while maintaining balance. For this reason, the foot in the shoe can also be fixed and held in a balanced manner by the belt portion 170 and the tongue-like contact portion 150.

4 is a schematic cross-sectional view taken along line AA ′ of FIG. That is, it is a schematic view showing a stitched state between the tongue-like contact portion 150 and the belt portion 170.
As shown in FIG. 4, the tongue-like abutment portion 150 is a contact layer which is placed on the foot insertion opening 160 side of FIG. 2, for example, a backing 151 made of a relatively flexible material Yes.
Further, as shown in FIG. 4, a cushion 177 is disposed between the lining 151 and the stretchable portion 174 of the belt portion 170.
For this reason, even if the foot in the shoe is pressed by the expansion / contraction part 174, it is configured to fit the back of the foot and abut the foot without feeling uncomfortable.
Moreover, the tongue-like abutment portion 150 has its front side, i.e., for example, a protective layer from the outside to be placed on the outside, has a outer material 153 made of a material having a relatively rigid.
As shown in FIG. 4, the stretchable portion 174 is sewn so that the outer material 153, the lining 151, and the cushion 177 are integrated, and the tongue-like contact portion 150 fits the foot while protecting the foot. It is configured to

Further, the tongue-shaped contact portion 150 is formed with an expansion / contraction guide portion 154 for expanding / contracting the expansion / contraction portion 174 in the arrangement direction of the virtual line V of FIG. 1 as shown in FIG. 2 and FIG.
That is, the tongue-shaped contact portion 150 is formed by stitching the expansion / contraction guide portions 154 at two locations, upper and lower, so as to restrict the direction and area in which the belt portion 170 moves.
Specifically, it is formed by stitching the outer material 153 and the lining 151 of FIG. 4 into a bag shape.
That is, the elastic guide portion 154 is formed by sewing the belt portion arrangement region of the tongue-like contact portion 150 corresponding to the elastic guide portion 154 into a bag shape so that the space between the outer material 153 and the lining 151 is hollow. Yes. Further, the belt portion 170 having the expansion / contraction portion 174 disposed in the middle is inserted into the expansion / contraction guide portion 154, and is integrally stitched by the expansion / contraction portion stitching portion 175, whereby the belt portion 170 and the tongue-like contact portion 150 are connected. It is united.

As shown in FIG. 2, by forming the expansion / contraction guide portions 154 and 154, the belt portion 170 can expand and contract in a direction different from the direction of the imaginary line V even when the expansion and contraction portion 174 is extended by an infant's operation. Can be prevented.
For this reason, even when an infant or the like violently attaches or detaches the infant shoe 100, the belt part 170 and the tongue-like contact part 150 are always positioned to securely hold and hold the foot, so that the infant can easily walk. Shoes 100.
As described above, according to the present embodiment, it is possible to provide a shoe that satisfies the requirements of ease of wearing and taking off of the infant shoe 100 and at the same time secures the foot holdability.

FIG. 5 is a schematic cross-sectional view in the region of the heel portion 130 of the shoe sole portion 110 of FIG. As shown in FIG. 5, the shoe sole portion 110 has a shoe sole layer 110a made of a sheet-like rubber material, EVA, or the like, and an outer cushion portion 110b and an inner cushion portion 110c are formed on the shoe sole layer 110a. Yes.
The inner cushion portion 110c corresponds to the inner foot side of the infant shoe 100, and is made of EVA, ethylene vinyl acetate copolymer, etc., and has a relatively hard material having a Shore A hardness of 45 degrees or more and less than 70 degrees. It is made up of.

It is made of a relatively soft material with a range of less than.
At this time, the inner cushion part 110c is configured to be harder than the outer cushion part 110b.

By the way, when the infant's age is from about 22 months to about 34 months, the infant can run and walk fast, and can move by jumping, rotating, walking on the crotch. However, although rolling of the soles begins to be observed, walking by the rolling of the soles is not yet completed, for example, the pressure when the heel touches the ground and the pressure when the thumb is separated is small.
Therefore, the infant at this stage cannot perform a rolling exercise well when walking, and has a tendency to fall inward where the foot falls inward.
In this regard, in the infant shoe 100 of the present embodiment, the inner cushion portion 110c is hard and the outer cushion portion 110b is softly formed in the heel portion 130. It is configured to encourage the foot pressure to move to the outer foot side of the foot when touched. Further, the cushion portions 110 are configured so as to become thinner sequentially from the heel portion 130 toward the arch portion of the foot, and only the shoe sole layer 110a is configured at the toe portion. Therefore, the infant shoe 100 is a shoe that prompts the infant to perform an appropriate rolling operation.

Further, as shown in FIG. 1, a belt holding portion 176 is formed on the distal end side of the outer foot side belt portion 172 of the belt portion 170 so as to protrude from the outer foot side belt portion 172.
For this reason, when the infant or the guardian of the infant operates the outer foot side belt portion 172, the belt holding portion 176 is held so as to be operated easily.
The belt holding portion 176 may be provided on both the inner foot belt portion 171 side, or may be provided only on the inner foot belt portion 171.

Further, as shown in FIG. 1, the upper part of the heel portion 130 of the footwear-out mouth 140 of the infant shoe 100, while being stretched so as to protrude from the Shaft portion 140, folded back temporary fixable heel A protruding piece 132 is formed.
That is, engagement means such as a hook-and-loop fastener (not shown) are formed on the heel side outer surfaces of the heel side protrusion 132 and the upper main body 120, respectively.
As shown in FIG. 1, the heel-side projecting piece 132 is folded back and can be fixed by changing (adjusting) its position on the outer surface of the upper main body 120, and its tip is located outside the upper main body 120. Once deep temporarily fixed to the footwear-out position spaced apart from the mouth portion 140 (heel side), the opening of the Shaft portion 140 is in a state of spread to deform outwardly.
For this reason, when the infant wears or removes the infant shoes 100 by himself / herself, the structure is easy to put on and take off.
Further, the tip of the heel protrusion 132 is temporarily fixed at a position not to deform the footwear-out mouth 140, when a state in which the upper body portion 120 rises, footwear-out mouth 140 to an upper high position of the heel of the foot The heel side comes into contact, and higher holdability can be exhibited. In addition, it is configured so that the infant's guardian can easily put the infant on and take off shoes by releasing the temporary fixing of the heel-side protruding piece 132 and holding the tip.

FIG. 6 is a schematic perspective view of the infant shoe 200 according to the second embodiment of the present invention in a state in which the tongue contact portion 250 is opened.
Since many configurations of the baby shoes according to the present embodiment are the same as those of the first embodiment, the same parts are denoted by the same reference numerals and the description thereof is omitted, and the differences will be mainly described below.
Infant shoe 200 along the outer leg side of the foot insertion opening 260 extending continuously connected from footwear-out mouth 2 4 0 has tongues abutting portion 250 is formed integrally with the upper body portion 220 The belt portion 270 extends so as to protrude from the side edge of the tongue-shaped contact portion 250 toward the inner foot side that is a free end.
That is, the tongue-like contact portion 250 is configured to open from the inner foot side toward the outer foot side.
Further, as indicated by a dotted line, an elastic part 274 is formed on the base side of the belt part 270 in the tongue-like contact part 250 and is fixed to the tongue-like contact part 250 by an elastic part stitching part 275.
A female side fastener 273 on the inner foot side is provided on the inner surface of the belt portion 270 and is configured to be engaged with a male side fastener 221 provided on the outer surface of the upper main body 220 while adjusting the position.

When the infant operates the belt portion 270 himself / herself, it is difficult to operate and adjust the belt portions 170 on the inner foot side and the outer foot side, so in the first embodiment, the helper such as a mother takes off. Although each belt portion 170 is operated when putting on, in the present embodiment, the belt portion 270 is formed only in one place, and is formed only on the inner foot side. ing.
By the way, when the inventor observed a state in which the belt portion was operated when wearing a pair of infant shoes with belts arranged on both sides for a plurality of infants, there were many infants who operated only the inner belt portion. It was. This is because infants often operate in the sitting position when the belt is operated, and since the hip joint is naturally open, it is easy to recognize the belt on the inner foot side and the inner side of the knee. This is because when the hand is extended from the outside, the distance is short compared to the outside of the knee, and the operation can be performed while visually recognizing.
Therefore, in the present embodiment, the belt portion 270 is disposed only on the inner foot side, and the engagement position on the outer foot side is not shifted by adopting a single-open structure that cannot be adjusted on the outer foot side, and The baby shoes 200 are easy for infants to operate on their own.

In addition, since the belt holding portion 276 is formed so as to protrude below the belt portion 270, it can be operated with the entire palm, not the fingertips, and is easy to remove for an infant.
Further, in this embodiment, although the heel protrusion 232 is formed, instead of the temporarily fixed, in a fixed state so as to spread to a position along the heel of the footwear-out mouth 240 outward, the upper It is fixed to the outer surface of the heel side of the main body 220 and only has a configuration that an infant can easily wear off.
Many of the other infant shoes 200 of the present embodiment have the same configuration as that of the first embodiment. Therefore, the ease of putting on and taking off and the holdability are substantially the same as those of the first embodiment. It is considered equivalent.
Instead of integrally formed tongue-like abutment portions 2 5 0 and the upper body portion 220 along the outer leg side of the foot insertion opening 2 60, similarly tongues those in the first embodiment forming a contact portion 2 5 0, may be formed by sewing the tongue abutment 2 5 0 etc. outer leg side of the foot insertion opening 2 60.
Further, as shown in FIG. 6, the sole layer 210 a of the shoe sole is formed so as to stand on the thumb side of the toe spring of the toe of the infant shoe 200.
