Description

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

In general, for shoes that take into consideration the ease of walking after inserting a foot, such as athletic shoes, that is, the holdability of the foot, the mouth for inserting the user's foot is formed relatively small. Tend to be tightened with shoelaces or the like. That is, if the shoe mouth or the like is formed to be relatively small, the shoe is difficult to take off and the foot is easily held by the entire shoe.
On the other hand, in the type of shoes that other people put on and take off shoes, such as shoes for infants, etc., unlike the sports shoes, in order to make it easier for others to attach and detach from the holdability after inserting the foot, Wear mouths tend to be formed relatively large. In this case, the user can easily insert the foot, but unlike the athletic shoe, the foot lacks holdability, so the foot is not sufficiently fixed in the shoe, and the shoe is difficult to walk.

However, in recent years, there has been a strong demand for shoes that are different from conventional ones and that have good holdability and are easy to walk, and that have large mouths and the like that allow easy insertion of feet. However, as described above, if the holdability is pursued, it becomes a shoe that is difficult to wear, and if pursuing ease of inserting a foot or the like with a large foot, the holdability is inferior and the shoe becomes difficult to walk.
Further, when both the high holdability and the size of the mouth and the like are obtained, it becomes a halfway shoe, which makes it difficult to walk and difficult to insert a foot, which is more problematic.
Therefore, a shoe having a tongue piece covering a part of the mouth has been proposed. However, if the fixation with the tongue piece is emphasized, the movement of the ankle or the like is obstructed. There was a problem such as moving.

  In view of the above points, the present invention provides a shoe that can be easily inserted and removed by a user and that can sufficiently fix the inserted foot, is easy to put on and take off, and has excellent holdability. With the goal.

According to the first aspect of the present invention, there is provided a shoe sole for arranging a sole side of a user's foot, and an upper body formed so as to stand up from the shoe sole and wrap the user's foot. And a heel portion for placing a heel of a user's foot, wherein the upper main body portion includes a mouth portion for inserting the user's foot, and the foot portion. 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, wherein the heel portion is a shoe sole side heel portion formed on the shoe sole portion and an upper main body formed on the upper main body portion. A side collar, and at least the upper body side collar is provided with a cowl to increase its rigidity. And the fixing belt portion is formed integrally with the tongue-like contact portion and is arranged so as to protrude from both sides thereof, and each end portion of the fixing belt portion. In the upper main body corresponding thereto, the fixing belt portion is detachably attached to the upper main body, and an engaging means for fixing the position in an adjustable state is formed. Each end portion is disposed in the vicinity of the outer edge portion of the counter portion, and an imaginary line connecting the substantially central portions in the width direction of the respective end portions of the fixing belt portion is extended as it is. In this case, the imaginary line reaches the boundary between the upper main body side heel part and the shoe sole side heel part in the heel part or the vicinity thereof, and the end of the fixing belt part is used as the imaginary line. As it is The fixing belt portion is provided so that the extended portion of the end portion is located at a boundary portion between the upper main body side heel portion and the shoe sole side heel portion when the length is long, and the tongue-like shape The fixing belt portions are arranged so that the foot height points on the instep of the user are located in the phantom line regions connecting the fixing belt portions arranged on both sides of the contact portion. , the shoe width direction central region of the tongue abutment is accomplished by the shoe, characterized in that has a structure that has the positioning portion is formed over the ankle side from the toe side of the shoe.

According to the configuration of claim 1, when the imaginary line connecting the substantially central portions in the width direction of the respective end portions of the fixing belt portion is extended as it is, the imaginary line is The fixing belt portion is provided so as to reach a boundary portion between the upper main body side heel portion and the shoe sole side heel portion or the vicinity thereof.
Therefore, through the fixing belt portion, the tongue-like contact portion acts to fix the user's foot around the direction of the heel portion of the shoe. For this reason, as compared to the case where the user's foot is fixed only in the shoe sole direction as in conventional shoes, the holdability is significantly improved, and the foot is fixed around the heel direction so that there is room on the shoe tip side. Therefore, it is possible to prevent the movement of the foot and the influence on the shape of the foot, which are caused by the movement of the foot in the shoe and difficulty in walking.

According to the present invention, at least the upper main body side collar portion is provided with a counter portion arranged to increase its rigidity.
Therefore, by arranging the counter portion, the rigidity of the upper main body side heel portion of the shoe is enhanced, and the heel of the user's foot is easily held accurately on the heel portion of the shoe.
That is, when the fixing belt portion acts to fix the user's foot toward the heel portion of the shoe as described above, the heel of the user's foot is moved through the counter portion having increased rigidity. Since it is pressed against the heel of the shoe and the heel of the foot is more securely fixed to the heel of the shoe, the holdability is significantly improved.
In addition, because the counter part has high rigidity, not only is it easy to move the foot along the counter part, but also the shoe is attached to and detached from the foot, such as preventing the heel part from deforming when wearing shoes. Cheap.

According to the present invention, each end portion of the fixing belt portion is disposed close to the outer edge portion of the counter portion.
Therefore, although the fixing belt portion is fixed near the strong counter portion and is securely held, the space between the counter portion and the fixing belt portion is not directly fixed, and the rigidity therebetween is Since it is not high, it can be slightly deformed according to the deformation of the foot when the user walks. For this reason, it becomes the structure which a user tends to deform | transform a leg | foot in the case of a walk, and it is the shoes which are easy to walk.
As a result, the user's foot is firmly fixed in the shoe, and it is easy to bend as necessary, so that the shoe is easy to walk.

Further, according to the present invention, the foot height point on the instep of the user is located in the region of the phantom line connecting the fixing belt portions arranged on both sides of the tongue-like contact portion. As described above, the fixing belt portion is arranged.

That is, when a region of an imaginary line connecting the fixing belt portion to the toe side of the toe side from the foot height point of the user's instep is arranged, the pressing force of the fixing belt portion is the instep of the foot. It is directed from the side to the sole of the foot, and the foot is pressed only on the sole side to fix the foot. In this case, it is not possible to hold the heel part where the movement of the foot in the shoe is large just by pressing the part of the foot instep, so the foot heel cannot be fixed, the foot is easily displaced and it is difficult to walk.
Moreover, if the area | region of the virtual line which tied the said fixing belt part is arrange | positioned at a user's ankle side, the movement which bends a user's ankle will be prevented.

  In this regard, in the configuration of this claim, the instep of the user is placed in the region of the phantom line connecting the fixing belt portions arranged on both sides of the tongue-like contact portion. Since the foot height point is placed on the foot, the foot heel should be fixed toward the heel of the shoe without unnecessarily pressing the instep against the sole and without disturbing the movement of the ankle. Therefore, it is possible to prevent the feet from moving in the shoes.

Further, in the configuration of the present invention, a foot insertion opening formed by cutting out a part of the wearing mouth portion toward the toe side direction and the foot insertion opening are disposed corresponding to the foot insertion opening. And a tongue-shaped contact portion.
Accordingly, if the opening for inserting the foot is widened and the tongue-like contact portion is opened, the shoe mouth portion opens sufficiently large, and the user or an assistant can easily put in and take off the foot. Become shoes.

  In addition, since the fixed belt portion is integrally formed so as to protrude on both sides of the tongue-shaped contact portion, the tongue-shaped contact portion can be moved only by attaching and detaching the fixing belt portion. It is possible to easily adjust the abutment strength of the tongue-shaped abutment part according to the opening and closing of the contact part and the adjustment of the position by the fixing belt part, and the fixing belt part protrudes on both the left and right sides. In correspondence with the difference in the shape and size of the foot, it can be worn with a balance between the left and right.

In addition, each end portion of the fixing belt portion and the corresponding upper main body portion can be attached to and detached from the upper main body portion so that the fixing belt portion can be fixed in a position-adjustable state. Combined means are formed.
Therefore, fixing and releasing the foot is merely by operating the engaging means between the end portion of the fixing belt portion and the upper main body portion, so that it can be attached and detached much more easily than when fixing with a string or the like. Since the position can be adjusted, it is possible to fix the shoe without distorting it according to the difference in the size or shape of the foot.

Moreover, according to the said structure, the positioning part is formed in the shoe width direction center area | region of the said tongue-like contact part from the toe side of shoes to the ankle side.
For this reason, it is easy for the user or an assistant to arrange the tongue-like contact portion on the left and right sides with this positioning portion, and the shape retaining property is enhanced by the positioning portion. Unnecessary distortion does not occur in the part corresponding to the instep part, and it is possible to prevent the tongue-like contact part from functioning reliably and obstructing the user's walking.
As described above, according to the configuration of the present claim, the user can easily put the foot or the assistant can easily put on the shoe, and after the shoe is worn, the foot is pressed against the heel portion of the shoe and fixed. As a result, the shoes are easy to walk with good holdability.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
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.

(First embodiment)
(Infant shoes for the walking practice period according to the first embodiment of the present invention (hereinafter, referred to as “the infant shoes 100”).
FIG. 1 is a schematic perspective view showing an infant shoe 100 according to a first embodiment of the present invention.
The infant shoe 100 as shown in FIG. 1 is aged, and the infant begins to be able to walk forward alone, while keeping the entire sole of the foot on the ground and balancing with the toes. It is a shoe for infants used after the so-called walking practice period, when walking begins.
Specifically, for example, an infant whose age is about 12 months is an object. The infant of this age becomes the age of the moon that begins to walk with his hands released.
As shown in FIG. 1, a shoe sole 110 for placing a sole of a foot of an infant or the like who is a user, and an upper main body formed so as to stand up from the shoe sole 110 and wrap the foot of an infant or the like. Part 120.

(About the shoe sole 110)
FIG. 2 is a schematic view showing a central longitudinal view of the infant shoe 100 of FIG.
As shown in FIG. 2, the shoe sole portion 110 has a shoe sole body 112 disposed on the front surface side, and an insole 111 is formed inside the shoe sole body 112.

(About the sole body 112)
The shoe sole body 112 is formed of a thermoplastic elastomer, synthetic rubber, natural rubber, or the like, which is an elastic member. Therefore, the shoe sole main body 112 is configured to absorb an impact during walking and to exhibit an anti-slip effect.
FIG. 3 is a schematic bottom view showing the sole body 112 of FIG.
As shown in FIGS. 2 and 3, a plurality of groove portions 112 a are formed on the toe side of the shoe sole body 112, and these groove portions 112 a are formed in the width direction of the shoe sole body 112.
For this reason, the sole body 112 is easily bent in the length direction of the sole body 112 at the position of the sole body 112a.
Further, the shoe sole body 112 is also formed with a plurality of different types of anti-slip portions 112b such as a circle, so that it is easy to walk without slipping.

(Regarding the relationship between the groove 112a and the toe bending line C, etc.)
By the way, when an infant or the like walks or stands on the tip of a toe, the heel is raised and the toes are bent or dorsiflexed well. At this time, the bent portion of the toes is called a toe bending line. Yes. FIG. 4 is a schematic explanatory diagram showing the foot skeleton and the like from above.
As shown in FIG. 4, the toes are arranged from the first toe on the thumb side to the fifth toe on the little finger side, and the area indicated by the arrow C in the figure, which is the middle toe joint of each finger and its periphery. A toe bending line or the like C which is the toe bending line or its vicinity is formed.
Since the torsional movement of the foot bent along the toe bending line C and the like is an important movement during walking and development of the foot, the walking cannot be performed well, and for the infant who has not developed foot development. For shoes, it is an important factor that the shoes are easy to bend along the toe bending line or the like C.

Of the sole body 112 of the infant shoe 100 according to the present embodiment, a portion corresponding to the toe bending line or the like C has a plurality of groove portions 112a, as shown in FIG. Is formed.
Therefore, when an infant or the like walks and bends a toe bending line or the like C, the groove 112a of the sole body 112 is also deformed and bent so as not to prevent the toe from being bent when the infant or the like walks. It has become.
Here, the groove portion 112a is formed so as to be easily bent. However, if the groove portion 112a is similarly easily bent, the sole body 112 is formed of a hard material, and a portion corresponding to the groove portion 112a is formed of a soft material. You may do it.

(Upper main body 120)
As shown in FIG. 1, an upper main body 120 formed so as to stand up from the shoe sole 110 and wrap a foot for an infant is disposed.
The upper main body 120 is formed of an upper main body 121, a wearing mouth portion 122, a foot insertion opening 123, a heel portion 140, and the like.

(Regarding the upper main body 121, the wearing mouth portion 122, and the foot insertion opening portion 123)
The upper main body 121 is covered with a soft material or the like that is entirely permeable to air, and an upper end portion of the upper main body 121 is provided with a mouth 122 for inserting a foot of an infant or the like as shown in FIG. Yes.
FIG. 5 is a schematic plan view showing a state in which a tongue piece 130 described later of the infant shoe 100 of FIG. 1 is opened to the toe side.
As shown in FIG. 5, a foot insertion opening 123 is formed in a substantially U shape in the toe side direction by cutting out a part of the wearing mouth portion 122.

Since the opening of the wearing mouth portion 122 and the opening of the foot insertion opening portion 123 form a continuous opening, it is possible to form a large opening through which an infant or the like can easily insert a foot.
In the present embodiment, the opening formed by the shoe mouth portion 122 and the foot insertion opening portion 123 formed in the upper main body 121 shown in FIG. 5 and the infant shoe 100 are shown in a plan view (FIG. 5). In this case, the maximum length G of the opening is, for example, about 75 mm to 90 mm, and the total length D of the infant shoe 100 is, for example, about 135 mm to 160 mm.
Therefore, the maximum length G of the opening is a large opening of 45% or more with respect to the total length D of the infant shoe, and it is extremely easy to insert a foot, easy to put on by a guardian, etc. Become.
The ratio of 45% or more may be 100%, but considering the shoe structure, it is preferably 45% to 55%, preferably 55% to 75%.
Further, as shown in FIG. 1, a counter loop 160 is formed in the vicinity of the wearing mouth portion 122 so as to be a clue when an infant or the like wears shoes.

(About the buttocks 140)
As shown in FIG. 1, a heel portion 140 for placing a foot heel of an infant or the like is formed across the upper body 121 and the shoe sole portion 110.
Specifically, the heel portion 140 includes a shoe sole side heel portion 142 formed on a part of the shoe sole portion 110 and an upper main body side heel formed on the upper main body 121 as shown in FIGS. 2 and 6A. It is comprised with the upper side collar part 141 which is a part.
In addition, as shown in FIG. 2, a counter unit 150 is disposed on the upper side collar 141 in order to increase its rigidity.
This is because, as described above, the upper main body 121 is made of a soft material, and thus the rigidity is insufficient to hold a child's bag.

On the other hand, the shoe sole side heel portion 142 is formed of a thermoplastic elastomer, synthetic rubber, natural rubber or the like whose sole body 112 is an elastic member and has sufficient rigidity to hold the heel. Although the portion 150 is not disposed, the counter portion 150 may be disposed on the shoe sole side heel portion 142.
The counter unit 150 is, for example, arranged in an arc shape when viewed from the side as shown by the hatched portion in FIG. 2 or FIG. 6, and is made of rubber or nonwoven fabric having a thickness of about 1.2 mm.
Thus, the rigidity is enhanced by arranging the counter unit 150 on the upper side heel part 141, and when fixed by the fixing belt 133 as will be described later, the foot part 140 of the infant or the like is attached to the heel part 140 of the infant shoe. The scissors are accurately held and easy to attach and detach.

(About tongue piece 130)
By the way, the tongue piece 130 which is a tongue-like contact portion is arranged as shown in FIG. 1 so as to close the substantially U-shaped foot insertion opening 123.
The tongue piece 130 is formed of a material having a certain rigidity such as polyurethane synthetic leather or micro suede, and can be fixed securely, and the inside is made of a material having high flexibility such as polyester or tricot.
In addition, the outer periphery of the tongue piece 130 and the fixing belt 133 may be piped with polyester or the like so as to suppress elongation or the like, and may be configured to improve finger contact when opening.
The tongue piece 130 has a base 131 that is a portion fixed to the upper main body 121. When the tongue piece 130 is disposed with respect to the foot insertion opening 123, It has an upper end portion 132 formed so as to be positioned higher than the upper end, and a fixing belt 133 which is a fixing belt portion for fixing the tongue piece 130 to the upper main body 121.

(About the base 131)
As shown in FIG. 1, the base 131 of the tongue piece 130 is a suture that is a tongue-like attachment region provided on the toe-side end of the substantially U-shaped foot insertion opening 123 or in the vicinity of the upper main body 121. The portion 124 is stitched or the like.
Since the tongue portion 130 is fixed by the stitching portion 124, the upper end 132 side of the tongue piece 130, which is the free end side, can be tilted to the toe side of the infant shoe 100 as shown in FIG. 5 opens the foot insertion opening 123 as shown in FIG. 5, and the tongue piece 130 does not get in the way when the foot is inserted and worn.
Therefore, the infant shoe 100 is easy for an infant or the like to easily put on and put on.
Further, as shown in FIG. 6, the stitching portion 131 is formed above the groove portion 112a shown in FIG. 3, particularly on the toe side.

FIG. 6 is a schematic left side view showing the left side and the counter portion of the infant shoe 100 of FIG.
As described above, the arrangement region of the groove 112a formed in the shoe sole portion 110 is a portion where the toe bending portion C of the foot of an infant or the like shown in FIG. 3 is arranged.
Therefore, the stitching portion 124 is formed above the toe bending line C or the like of the foot of an infant or the like.
By the way, the stitched portion 124 becomes a weaker portion than the other portion of the upper main body 121 by stitching or the like, and is therefore a portion that is easily bent in the direction of rotation around the stitched portion 124.
Accordingly, when an infant or the like bends the toe bending portion C of the foot during walking, the suturing portion 124 of the upper main body 121 thereabove is also bent by the bending operation, and necessary bending of the toe is performed during walking. The shoes are easy to walk without hindering.

In particular, since the groove 112a of the shoe sole body 112 is also bent corresponding to the toe bending line C, the shoe sole portion 110 and the upper body 112 are bent corresponding to the toe bending of an infant or the like. The position of the bend line C is easy to bend, and it becomes an easy-to-walk infant shoe.
FIG. 7 is a schematic explanatory view showing a state where an infant or the like wears the infant shoes 100 and is walking with the toes bent.
As shown in FIG. 7, the groove portion 112a of the shoe sole portion 110 and the stitching portion 124 of the upper main body 112 are bent in response to the bending of the toes.

(About fixed belt 133)
As shown in FIG. 1, fixing belts 133 that are fixing belt portions are formed on both sides of the tongue piece 130. The two fixing belts 133 are integrally formed with the tongue piece 130 and are arranged substantially symmetrically so as to protrude from both sides of the tongue piece 130.
As shown in FIG. 5, belt side fasteners 133a as engaging means are formed on the inner side of the tip, which is the end of the fixed belt 133, respectively.
Further, an upper side fastener 121a is formed corresponding to the belt side fastener 133a as shown in FIG.

For this reason, the belt side fastener 133a and the upper side fastener 121a are configured to be engaging means that can be easily detached and adjusted in position when a mother or the like such as an infant operates the infant or the like. .
Therefore, fixing and releasing the foot with respect to the infant shoe 100 only operates the engagement state between the belt side fastener 133a and the upper side fastener 121a at the tip of the fixing belt 133, so that a string or the like can be used as in the prior art. It is possible to attach and detach very easily compared with the case of fixing by the above.
In addition, since the engagement position between the belt side surface fastener 133a and the upper side surface fastener 121a can be adjusted, the belt side surface fastener 133a is fixed at an arbitrary position corresponding to a difference in shape such as the size of the foot of the infant and the thickness of the ankle. be able to. At this time, since the belt side fastener 133a is formed larger than the upper side fastener 121a, the belt side fastener 133a can be adjusted to an appropriate position.
Further, since the fixing belt 133 is formed so as to protrude on both sides of the tongue piece 130, the fastening force can be made uniform, and the upper 120 can be fixed without being distorted.
Here, the hook-and-loop fasteners 133a and 121a are substantially rectangular, but may be extended toward the foot insertion opening 123 so that the bonding strength of the fixing belt 133 can be increased and fixed securely.

(Regarding the relationship between the fixing belt 133 and the collar 140)
As shown in FIG. 6, when an imaginary line H connecting substantially the center portions in the width direction of the respective leading ends of the fixing belt 133 is extended as it is, this imaginary line H is shown in FIG. The fixing belt 133 is disposed so as to reach the boundary portion between the upper side heel portion 141 and the shoe sole side heel portion 142 or the vicinity thereof.
Further, by extending this imaginary line H, an angle θ at a portion intersecting the imaginary line K of the placement surface (floor) shown in FIG. 6A is, for example, 30 degrees to 40 degrees.
Therefore, an infant or the like wears the infant shoes 100 and fastens the fixing belt 133 as shown in FIG. That is, when the belt side fastener 133a at the tip of the fixing belt 133 is engaged with the upper side fastener 121a, the fixing belt 133 acts to fix the foot of an infant or the like in the direction of the heel portion 140 of the infant shoe 100. Will do.

  As a result, the infant shoe 100 of the present embodiment has significantly improved holdability compared to the case where the foot of an infant or the like is fixed to the shoe bottom 110 side in a substantially vertical direction as in the conventional infant shoe, In order to prevent the foot from slipping toward the toe side, the foot can be held on the shoe without hindering toe flexion or dorsiflexion associated with walking of an infant etc. . In addition, since the foot can move in the infant shoes 100 and it is difficult to walk, the effects on the carrying of the foot and the shape of the foot can be prevented in advance. There will be no infant shoes 100.

The fixing direction of the fixing belt 133 is the direction of the collar 140 as described above, and the counter section 150 is disposed on the collar 140 as shown in FIG. The rigidity of the collar 141 is increased.
For this reason, when a foot of an infant or the like is fixed in the direction of the heel portion 140 of the infant shoe 100 by the fixing belt 133, the foot heel of the infant or the like is attached to the infant shoe 100 via the counter portion 150 having increased rigidity. Since it is pressed against the heel part 140 and the heel of the foot is more securely fixed to the heel part 140, the holdability of the foot of an infant or the like to the shoe is significantly improved.
Furthermore, it is easy to move the foot along the counter unit 150, and the upper side heel portion 141 is not deformed particularly when the shoe is worn, so that the shoe can be easily attached and detached.

By the way, as shown in FIG. 6, the two front end portions of the fixed belt 133 are arranged close to the outer edge portion 151 of the counter portion 150.
Therefore, the tip part which is the two ends of the fixed belt 133 is not directly fixed to the counter unit 150.
Therefore, the tip portion and the outer edge portion 151 of the counter portion 150 are not directly fixed, and the space between the tip portion and the soft material of the upper main body 121 is between them, and the rigidity of the separation portion is not high. According to the deformation of the foot accompanying the toe and ankle flexion performed during walking, the separated portion which is the soft material portion is deformed, and the foot is not burdened.
For this reason, the foot of an infant or the like is firmly fixed in the infant shoe 100, and the separated portion, which is a soft material portion, is deformed as described above, so that it is easy for an infant or the like to walk.

(Relationship between tongue piece 130 and foot height, etc.)
FIG. 8 is a schematic explanatory diagram viewed from the side of the human foot skeleton and the like.
As shown in FIG. 8, a person's foot has a portion referred to as a foot height point B at a portion indicated by an arrow B.
FIG. 9 is a schematic plan view showing a plane of the infant shoe 100 of FIG.
As shown in FIGS. 1 and 9, the infant shoe 100 according to the present embodiment is sandwiched between virtual lines on the upper edge side and the lower edge side in the center portion of the tongue piece 130 connecting the two fixing belts 133. The tongue piece 130 is configured so that the foot height point B of FIG. In particular, the foot height point B is preferably located on the lower edge side in the foot height virtual region I.
Therefore, it is effective that the fixing belt 133 presses the instep of an infant or the like perpendicularly to the shoe bottom 110 direction, and the heel is not fixed, and the holdability of the foot in the infant shoe 100 is reduced. Can be prevented.

That is, when the foot height virtual point I of the two fixing belts 133 is arranged on the toe side in FIG. 1 from the foot height B of the instep of an infant or the like, the pressing force of the fixing belt 133 is The foot is directed from the back side of the foot to the back side of the foot in the vertical direction, and the foot is pressed only against the shoe sole 110 side to fix the foot.
In this case, it is not possible to fix the heel with a large movement of the foot in the infant shoes 100 simply by pressing the instep portion, the displacement of the entire foot in the front-rear direction, the displacement of the heel in the up-down direction, etc. Can not be prevented, the foot is easily slipped in the shoes, it becomes difficult to walk.
Further, when the foot height virtual region I connecting the lower edge portions of the two fixing belts 133 is arranged on the ankle side of an infant or the like, the movement of the ankle of the infant or the like to be bent is hindered.

On the other hand, if the pressing force of the fixing belt 133 is reduced in consideration of the bending of the foot, the foot is not fixed in the shoe, and the shoe becomes difficult to walk.
In this regard, in the infant shoe 100 of the present embodiment, the foot height virtual region sandwiched between the imaginary lines on the upper edge side and the lower edge side in the central portion of the tongue piece 130 connecting the two fixing belts 133. In particular, the tongue piece 130 and the fixing belt 133 are arranged so that the foot height point B of FIG. The foot is not pushed in the direction substantially perpendicular to the shoe bottom 110 direction, and the foot is held so as not to move in the front-rear direction from the foot height point B, which is clearly higher, toward the heel portion 140 of the infant shoe 100. In addition, since the movement of the heel in the vertical direction is also prevented, the foot can be fixed to the shoe without hindering the toe bending of an infant or the like, and the holdability is improved.
That is, since the virtual region I connecting the fixing belt 133 can be effectively prevented from being placed on the toe side of the toe side from the foot height B, the infant's foot can be more accurately attached to the buttocks of the infant shoe 100. The infant shoe 100 can be held toward the 140 side and the holdability of the foot of an infant or the like is further increased.
Further, since the virtual region I connecting the fixing belt 133 can be prevented from being placed on the ankle side of an infant or the like, the movement of the ankle of the infant or the like is not hindered.

As shown in FIGS. 1 and 9, the fixing belt 133 is formed integrally with the tongue piece 130, and is disposed substantially symmetrically so as to protrude in the left and right directions that are both sides thereof.
Therefore, when the fixing belt 133 is operated to fix the foot of an infant or the like, distortion of the infant shoe 100 due to a bias in the tightening amount of the fixing belt 133 can be reduced. Moreover, since force is equally applied to the two fixing belts 133, force can be correctly applied in the direction of the saddle point from the foot high point side of the instep of FIG. The heel portion 140 of the shoe 100 can be securely held.
That is, since it is fixed by the fixing belt 133 formed so as to protrude on both sides of the tongue piece 130, the foot can be held in the shoe firmly and well balanced by the tongue piece 130 and the fixing belt 133.

(About the upper end 132)
As shown in FIG. 1, when the tongue piece 130 is arranged with respect to the foot insertion opening 123, an upper end portion 132 is formed so as to be positioned higher than the upper end of the wearing mouth portion 122.
The upper end portion 132 prevents the insertion opening 123 from creating a gap in the front direction of the foot when the infant shoe 100 is worn, and the tongue piece 130 wraps the foot of the infant or the like in a wider area. Therefore, the infant shoe 100 has a high holdability with respect to the foot shoes, in particular, an ankle holdability.

By forming the upper end portion 132 on the tongue piece 130 as described above, the holdability of the foot is enhanced, but conversely, the bending of the ankle performed during walking may be hindered by the upper end portion 132 being bitten.
For example, as shown in FIG. 7, when the ankle of an infant or the like is bent toward the toe side, the upper end portion 132 of the tongue piece 130 may come into contact with the ankle of the infant or the like, thereby preventing the ankle from bending.
Therefore, in the infant shoe 100 of the present embodiment, the stitch 132a, which is a bending deformation portion, is formed with a curved line that bulges toward the toe side on a virtual line connecting the upper edge portions of the two fixing belts 133.
The stitch 132a is formed by stitching or the like, and the stitch 132a facilitates deformation of the upper end portion 132 with the base side stitch 132a as a rotation axis.
Then, the deformation of the stitch 132a causes the deformation of the upper end portion 132 as shown in FIG. 7, specifically, bending toward the toe side following the bending of the ankle. An infant shoe 100 that is easy to walk and does not hinder bending is provided.

(About insole 200)
As shown in FIG. 2, an insole 200, which is a removable insole, is provided on the inner bottom 111 of the infant shoe 100 of the present embodiment.
FIG. 10 is a schematic bottom view of the insole 200, and FIG. 10 (b) is a schematic cross-sectional view taken along the line AA ′ of FIG. 10 (a).
As shown in FIG. 10A, the insole 200 is formed in accordance with the shape of the midsole 111 of the infant shoe 100, and is made of a soft material such as foamed EVA resin or foamed polyethylene.
As shown in FIGS. 10A and 10B, for example, six bending grooves 201 are formed on the bottom surface side of the insole 200.

The plurality of bending groove portions 201 are curved in a region similar to the groove portion 112a formed in the shoe sole body 112 in FIG. 3, that is, a curve bulging toward the toe side at a position corresponding to a toe bending line or the like C. Is formed.
Such an insole 200 is disposed in order to improve the fit in the shoe or to adjust the size when the foot of an infant or the like is slightly smaller than the size of the shoe 100 for the infant.
Even when the insole 200 is arranged on the midsole 111 of the infant shoe 100 in this way, in the present embodiment, the insole 200 has the same bending groove 201 as the groove 112a of the shoe sole body 112 in the same shape. It is provided in the position.
Therefore, when the toddler or the like performs toe bending or the like as described above when walking, the insole 200 does not hinder the bending, and the infant shoe 100 is easy to walk.

(About toe upper 125)
FIG. 11 is a schematic cross-sectional view showing a state where the toe upper 125 of the infant shoe 100 of FIG. 1 is cut in the shoe width direction.
The toe upper 125 is covered with a synthetic leather or the like on the soft material of the upper main body 121, for example, or is reinforced like the counter 150, so that the rigidity can be increased more than other parts. It is configured.
Specifically, the synthetic leather or the like of the upper 125 has its outer edge portion 125a shown in FIG. 1 arranged at the position of the stitching portion 124 or on the toe side, so that the toes are bent as shown in FIG. In doing so, the outer edge portion 125a is also stitched without hindering the bending of the stitching portion 124 and the like, so that it functions as a fragile portion and is easily bent using the outer edge portion 125a as a rotation axis.
On the other hand, the toe upper 125 itself, which is the toe part of the infant shoe 100, also needs to be more rigid than the other parts in order to protect the toe part. Rigidity is increased as long as it does not interfere.

Also, as shown in FIG. 11, the height of the infant shoe 100 inside the toe upper 125 is thickest at the portion where the thumb of the infant's foot is disposed, and gradually becomes thinner toward the portion where the little finger is disposed. It is formed as follows.
That is, the gap in the vertical direction between the thumb on the inside of the toe upper 125 is formed to be larger than the gap between the other toes and the inside of the toe.

In this way, the gap is formed between the thumb and the toe portion so that even if the dorsiflexion of the thumb is performed during walking, which is a movement often seen in infants, This is because the toe portion does not hinder.
By doing this dorsiflexion of the thumb, not only the balance of the body at the time of walking is maintained, but also the movement of the muscles of the foot, the flat foot is prevented in advance, and the development of the motor function in walking is promoted.
In this way, in order for the infant to keep a balance when walking, the thumb can be dorsiflexed inside the infant shoe 100, so that the walking practice can be performed smoothly.

(About side leather part 126)
As shown in FIG. A side leather portion 126 is formed on the side surface of the shoe along the shoe bottom portion 110 in the upper main body portion 120 of the infant shoe 100.
The side leather portion 126 is provided with synthetic leather or the like in the same manner as the toe upper 125.
Further, in FIG. 1 of the side leather portion 126, a notch 126a is formed in the vicinity of the toe upper 125, and the side leather portion 126 is partially thinned.
Even if the little finger shown in FIG. 11 is widened outward, the notch 126a contacts the soft material portion of the upper main body 121 and does not contact the side leather portion 126. At this time, since the upper main body 121 is soft, the movement of the little finger is not hindered and the little finger is easily spread.
Further, with respect to the toe upper 125, as shown in FIG. 11, a gap is formed outside the portion where the little finger is disposed, and the width becomes the width of the shoe sole portion 110. The movement of opening the finger together with the notch 126a It is configured not to disturb.

That is, toddlers or the like try to maintain balance by spreading their toes when walking, when they are staggered.
In particular, it is known that the balance is maintained by widening the little finger outward.
Therefore, the infant shoe 100 according to the present embodiment is a shoe in which an infant or the like easily balances when walking, so that the thumb is easily bent and the little finger is easily spread.
Further, the notch 126a is formed in the vicinity of the toe bending line C shown in FIG. 4 as in the case of the groove 112a in the sole body 112 and the stitched portion 124 in the upper 120.

For this reason, as shown in FIG. 7, when a toe is bent by walking or the like, it is easily bent because the rigidity is weakened by being cut out.
Further, the side of the thumb shown in FIG. 6 is also curved so as to dent the side leather portion 126, so that although there is no notch, the rigidity is similarly reduced due to the bending, and it is easily bent.
Further, as shown in FIG. 6, the toe portion is formed with a toe spring 129 that warps toward the tip, so that it is difficult for an infant who tends to walk as if dragging his / her foot to trip. Yes.

(About usage of infant shoes 100)
The infant shoe 100 according to the present embodiment is configured as described above, and the following usage method and the like will be described.
Here, an example in which a mother or the like who is a caregiver causes an infant that is a child to wear the infant shoes 100 will be described as an example.

First, the mother grasps the two fixing belts 133 of the infant shoe 100 shown in FIG. 1 and releases the engagement of the hook-and-loop fasteners 133a and 121a.
Thereafter, the upper end portion 132 of the tongue piece 130 shown in FIG. 5 is gripped, and the other portion, which is a free end, is tilted toward the toe side of the shoe with the fixed end on the suture portion 124 side of the tongue piece 130 as the center. FIG. 5 shows this state.

As shown in FIG. 5, the maximum length G of the opening formed by the mouth opening 122 and the foot insertion opening 123 reaches, for example, about 60% compared to the total length D of the infant shoe 100, and thus is significantly larger. An opening can be formed.
Therefore, the counter unit 150 may be rigid, and the infant shoe 100 is easy for the mother to easily insert and put on the infant's foot.

Next, contrary to the above, the mother returns the tongue piece 130 to the state shown in FIG. 1, engages the hook-and-loop fasteners 133 a of the two fixing belts 133 arranged on both sides with the hook-and-loop fastener 121 a of the upper main body 121, and moves the position. Fix while adjusting.
Therefore, unlike fixing with a string or the like, the mother or the like can easily put the infant shoes 100 on the infant. Further, since the position of the fixing belt 133 can be adjusted, the fixing belt 133 can be disposed at an appropriate position, so that the infant's shoes 100 can be put on the infant in an optimum state.
At this time, as shown in FIG. 9, the fixed belt 133 is disposed at a substantially symmetrical position. For this reason, the infant shoe 100 is not distorted due to excessive tightening of the fixing belt 133.

Further, the fixing belt 133 does not press the instep of the infant in the shoe sole direction but fixes it in the heel direction, so that the foot is fixed inside the shoe without interfering with walking.
Therefore, the infant shoe 100 of the present embodiment is a shoe that a mother or the like can easily put on an infant or the like, and after the shoe is worn, the foot is fixed toward the buttocks 140 of the infant shoe 100. Therefore, the infant shoe 100 is easy to walk with high holdability and does not hinder growth and development.
In particular, infants in the early stages of walking have not developed walking ability, and if their feet are misaligned in the shoes for infants, they cannot change their feet, which may affect the way they fall or how they move. There were many problems such as coming out. In the infant shoe 100 according to the present embodiment, since the foot heel of an infant or the like is firmly held by the heel portion 140 of the infant shoe 100, the position of the foot is difficult to shift in the shoe.
In addition, in the case of infant shoes with a margin (gap) on the toe side of the shoe so as not to hinder the movement of the toes of infants, etc., the position of the foot in the shoes is shifted in the front-rear direction. The possibility that it will end up increases.

  In the infant shoe 100 according to the present embodiment, even if the infant shoe is arranged with a gap on the toe side, the foot heel of the infant or the like is firmly held by the heel portion 140 of the infant shoe 100. Therefore, it is the infant shoes 100 in which the position of the foot is difficult to shift in the shoes.

(Second Embodiment)
Of the configuration of the infant shoes (hereinafter referred to as “infant shoes”) 300 in the walking practice period according to the second embodiment, the portions that overlap the configuration of the infant shoes 100 of the first embodiment described above are as follows. The description will be omitted with the same reference numerals and the like, and the following description will focus on the differences.
FIG. 12 is a schematic perspective view showing an infant shoe 300 according to the present embodiment.
The infant shoe 300 includes a shoe sole portion 310 and an upper main body portion 320 as in FIG.

(About shoe sole 310)
FIG. 13 is a schematic view showing a central longitudinal view of the infant shoe 300 of FIG.
As shown in FIG. 13, the shoe sole portion 310 has a shoe sole main body 312 disposed on the surface thereof, and an insole 311 is formed inside the shoe sole main body 312.

(About the wear mouth 322 etc.)
The upper main body 321 is covered with a soft material or the like having a high air permeability as in the case of the upper main body 112 in FIG. 1, and a foot of an infant or the like is inserted into the upper end portion of the upper main body 321 as shown in FIG. A mouth 322 is formed for this purpose.
FIG. 14 is a schematic plan view of the mouth 322 in FIG. 12 in an open state.
Further, as shown in FIG. 14, a foot insertion opening 323 is formed so as to be connected to the wearing mouth 322.
As described above, since the wear mouth 322 and the foot insertion opening 323 are formed to be connected to each other, like the infant shoe 100, it is possible to form a large opening where an infant or the like can easily attach and detach the foot. It has become.

As shown in FIGS. 12 and 13, for example, a sponge 322 b serving as a buffer means is disposed inside the opening end 322 a of the wearing mouth 322.
The sponge 322b is made of a material such as polyurethane or EVA, for example.
By arranging the sponge 322b at the opening end 322a of the mouth portion 322 as described above, the mouth portion 322 is softly abutted on the user's ankle, so that the comfort is improved and the ankle can be prevented from bending. No.
FIG. 15 is a schematic view showing an arrangement state of the counter unit 150 and the like.

(About the tongue 330 etc.)
By the way, as shown in FIG. 15, a tongue piece 330 which is a tongue-like contact portion is arranged corresponding to the foot insertion opening 323.
The tongue piece 330 corresponds to the foot insertion opening 323 of the upper main body 320 and closes the mouth piece, that is, as shown in FIG. The upper end portion 331 (see FIG. 15) is positioned so as to protrude upward from the wearing mouth portion 322.
For this reason, when the user wears the infant shoes 300, the tongue piece 330, particularly the tongue piece upper end portion 331, is arranged along the ankle without being separated from the user's ankle.
That is, it is possible to prevent a gap between the user's ankle and the tongue piece 330 from occurring, and to prevent unnecessary movement of the foot in the infant shoe 300, so that the user can easily walk. 300.
In addition, the fit when the user wears the infant shoes 300 is improved, and the bent portion of the user's ankle is appropriately fixed by the tongue piece 330.

Meanwhile, for example, a buffer portion 333 that is a buffer layer is disposed on the inside of the tongue piece 330 on the side of the mouth portion 322 (inner side of the shoe) as shown in FIG.
The buffer portion 333 is formed by, for example, a sponge such as styrene butadiene rubber (SBR) or polyurethane (please give an example) covered with a lining.
In addition, a rigid portion 332 that is a rigid layer is disposed outside the buffer portion 333 in FIG.
The rigid portion 332 is formed of, for example, an interlining 332b such as canvas or tricot (TC) and an outer surface 332a made of synthetic leather or natural leather such as microsuede or polyurethane, and has a strength that is relatively difficult to deform. have.

By removing the rigid portion 332 on the side of the mouth portion 322 in FIG. 13 of the tongue piece 330 formed in two layers in this way, for example, a cushion portion 331a which is a buffer means having stretchability is formed.
In addition, from the boundary line of this rigid part 332 and the cushion part 331a to the cushion part 331a corresponds to the bending deformation part in a present Example.
That is, as shown in FIGS. 14 and 15, the cushion portion 331 a is formed in a substantially semicircular shape, for example, at a part of the tongue piece upper end portion 331 of the tongue piece 330.

FIG. 16 is a schematic explanatory diagram illustrating a user's walking state and the like.
As shown in FIG. 16, when the user stands on the toe or walks, the cushion portion 331a expands and contracts following or flexing the ankle, so that the tongue piece 330 inhibits the movement of the user's ankle. Accordingly, the user can move the ankle more naturally, and the infant shoe 300 is easy to walk.
That is, unlike the conventional shoes, when the user walks, the upper end portion of the tongue piece does not bite into the bent portion of the ankle.
In addition, when the infant shoe 300 is worn, the tongue piece upper end 331 does not bite into the ankle, so that the tongue piece 330 can be firmly attached.

  Further, since the cushion portion 331a can be formed by removing a part of the rigid portion 332 from the tongue piece 330, the cushion portion 331a can be easily provided as compared with the case where another cushion portion is further provided, and the cost can be reduced. it can.

17 is a schematic sectional view taken along line YY ′ of FIG.
FIG. 17 is a schematic enlarged view of a portion indicated by an arrow Z in FIG.
As shown in FIG. 17, the rigid portion 332 has a surface material 332a and an interlining 332b. Since the outer material 332a and the interlining 332b have strength, the structure is strong and hardly deformed easily.
On the other hand, as shown in FIG. 17, the buffer portion 333 is configured such that the sponge 333a is sandwiched between the linings 333b. As described above, since the sponge 333a is formed of styrene butadiene rubber (SBR), polyurethane, or the like, the sponge 333a is configured to have elasticity and elasticity.
In addition, as shown in FIG. 17, the cushion portion 333 is folded back and the end portion is located below the rigid portion 132, and the cushion portion 333 is substantially double in the cushion portion 331a. Therefore, the elasticity and the like are further improved.

FIG. 18 is a schematic plan view of FIG.
As described above, since the cushion portion 331a is configured, when the tongue piece 330 is disposed so as to close the foot insertion opening 323 of FIG. 14, as shown in FIG. The shoe mouth of the shoe 300 is surrounded by an opening end 322a having a sponge 322b and a cushion 331a.
For this reason, as shown in FIG. 16, the user's ankle abuts against the opening end 322a and the cushion portion 331a over the entire circumference, so that the opening end 322a and the cushion portion 331a softly abut on the ankle and fit to the ankle. It will be.
In addition, since the opening end 322a and the cushion portion 331a abut against the user's ankle, even if the tongue piece 330 is firmly pressed against the ankle side, the sponge 322b and the cushion portion 331a of the opening end 322a are firmly fixed. The sponge 333a is deformed.
For this reason, even if the tongue piece 330 abuts securely, the user's ankle bend as shown in FIG. 16 is held without hindering, and the holdability of the infant shoe 300 with respect to the ankle is improved.
In particular, a user who has not yet developed bones and muscles such as an infant can practice safely without hindering growth.

(About fixed belt 135)
As shown in FIG. 12, fixing belts 335 and 335 that are fixing belt portions are formed on both sides of the tongue piece 330. The two fixing belts 135 and 135 are formed integrally with the tongue piece 330, and are disposed on both the inner and outer legs of the upper body 321 from both sides of the tongue piece 330, respectively.
As shown in FIG. 14, the fixing belt 335 is formed such that the inner foot side length (L1) is shorter than the outer foot side length (L2) by, for example, about 5 mm from the center line in the width direction of the tongue piece 330. . At this time, the length (L1) on the inner foot side is set to 85% to 95%, preferably 90% to 95%, with respect to the length (L2) on the outer foot side.
This is due to the following reason. FIG. 19 is a schematic skeleton diagram seen from the front of a person's foot. As shown in FIG. 19, the highest part of the instep is called the foot height point B. As shown in FIG. 19, the length (L1) on the inner foot side from the foot height point B and the foot side on the outer foot side. The length (L2) is not the same, and the inner foot side is shorter.
Corresponding to the difference on the skeleton, the length (L1) on the inner foot side in FIG. 14 is formed short.
For this reason, the fixing belt on the inner foot side is too longer than the length (L1) of the skeleton of the foot as in the prior art, and play occurs, and the fixing belts on the inner foot side of the left and right infant shoes 300 contact each other. It can prevent obstructing walking.

Further, by forming the inner foot side fixing belt 335 shorter than the outer foot side fixing belt 335 in this way, when the tongue piece 330 is arranged as shown in FIG. The center stitch portion 334 (see FIG. 12) disposed at the substantially central portion of the foot is easily mounted so as to be disposed at the above-described foot height point B.
Thereby, since the tongue piece 330 can be arrange | positioned in a right position along the frame | skeleton of a person's leg, the holding | maintenance by the tongue piece 330 will be performed with a sufficient precision.

(About center stitch part 334 etc.)
By the way, as shown in FIG. 12, for example, a center stitch portion 334 which is a positioning portion from the toe side toward the ankle side is formed in the center region in the width direction of the tongue piece 330.
FIG. 20 is a schematic partial cross-sectional view taken along the line XX ′ of FIG. As shown in FIG. 14, the center stitch portion 334 is formed by folding the outer surface 332a of the rigid portion 332 on the interlining 332b and stitching it in a double state.
That is, the stitching of the outer material 332a further increases the rigidity and the shape retention.
The center stitch portion 334 has a reverse warp shape as shown in FIG. 12, and is formed on the instep of FIG. 8 along the shape.
Therefore, since the tongue piece 330 of FIG. 12 is arranged and held along the shape of the instep, unnecessary distortion does not occur in the portion corresponding to the instep portion of the tongue piece 330, and Since it touches the back of the foot evenly on the left and right, it is possible to prevent obstructing the user's walking.

Moreover, the center stitch part 334 is arrange | positioned on the foot height point B of FIG. 19, when the tongue piece 330 is arrange | positioned like FIG. When the two fixing belts 335 and 335 are fixed to the upper body 321 with the belt side fastener 135a or the like, a force acts from the center stitch portion 334 toward the belt side fastener 135a or the like as indicated by an arrow in FIG.
However, since the center stitch part 334 has high rigidity and shape retention, it is difficult to deform. For this reason, since force acts equally on both sides toward the left and right belt side fasteners 135a and the like with reference to a substantially central portion in the width direction of the foot, the tongue piece 330 can be attached to the upper body 321 with high accuracy.

Furthermore, since the fixing belt 335 can be fixed while visually recognizing the center stitch portion 334, the center stitch portion 334 also functions as a positioning portion for reliably positioning the foot on the foot height point B.
That is, the fixing belt 335 can make the tightening force equal to the left and right, and can be fixed without distorting the upper 320.

(Regarding the relationship between the fixing belt 335 and the collar 140)
As shown in FIG. 15, when the virtual line H connecting the substantially central portions in the width direction of the respective distal end portions of the two fixing belts 335 and 335 is extended as it is, like the above-described infant shoe 100, The fixing belt 335 is arranged so that the imaginary line H reaches the boundary portion between the upper side heel portion 141 and the shoe sole side heel portion 142 shown in FIG.

Further, the stitching line 334a by stitching the center stitch portion 334 in FIG. 12 is configured such that the stitching line 334a intersects the virtual line H substantially perpendicularly as shown in FIG.
For this reason, the force is easily applied to the fixing belts 335 and 335 on both sides with reference to the suture line 334a as shown by the arrows in FIG. 15, so that the tongue piece 330 can be attached to the upper body 321 with high accuracy. .
As a result, the infant shoe 300 of the present embodiment ensures that the tongue piece 330 is fixed at an appropriate position in a state along the instep of the infant shoe 100 of the first embodiment. Can do.
In addition, the foot can be held on the shoe without hindering the bending or dorsiflexion of the toes and ankles associated with walking of an infant or the like. Furthermore, since the foot moves in the infant shoes 300 and the influence on the movement of the foot and the shape of the foot due to difficulty in walking can be prevented in advance, it is easy to walk and hinders growth and development. It becomes the infant's shoes 300 which are not.

(Third embodiment)
FIG. 21 is a schematic perspective view showing an infant shoe 400 (hereinafter, referred to as “infant shoe 400”) in the transmission period according to the third embodiment of the present invention.
An infant in the walking stage who wears the infant shoes 400 shown in FIG. 21 is, for example, an infant of 8 to 12 months of age, and the walking form is grasped on a desk or the like and the power of the hand is used. It is a state which moves sideways while doing. And, in this “holding standing”, there is a characteristic of trying to walk while standing on the toes or standing on the toes or standing on the toes.

Unlike the infant shoes 100 and 300 of the other embodiments, the infant shoe 400 of the present embodiment is used for the walking period, and thus has a slightly different configuration. It is the same as that of the infant shoes 100 and 300 of the form.
For this reason, configurations that are substantially the same as those of the other embodiments are omitted as the same reference numerals and the like, and hereinafter, differences will be mainly described.
In the present embodiment, the shoe sole 410 is thinner than the shoe sole 310 of the infant shoe 100 and is formed to be easily bent.
In addition, the foot of the infant at this time may be swelled, and unlike the tongue piece 330 of the infant shoe 300, the center stitch portion 334 is not formed on the tongue piece 430.
This reduces the rigidity of the infant shoes 400 as a whole and forms a relatively soft whole so that the toe standing etc. is performed in the case of a “holding standing” performed by an infant who is inferior in walking function and is walking. It is also to make it easier.
In addition, the cushion portion 431a has a substantially crescent shape substantially the same width as the upper end portion 431 of the tongue piece, and is configured to reliably surround the ankle together with the open end portion 422a. In addition, the lower edge portion of the belt portion 435 For example, the side is curved so as to be slightly depressed upward, so that the softly swollen foot during the walking period is not compressed.
