Description

[Technical Field]

[0001] To provide footwear that can be easily put on by inserting a foot into the footwear and putting weight on the heel, so that the foot can slide into the footwear without using a shoehorn or hands. [Background technology]

[0002] Conventionally, when putting on footwear, it has been common to open the opening, insert the foot, place a shoe horn in the heel part, and place the heel part of the foot against the shoe horn to put the foot into the footwear. However, such conventional footwear requires the user to keep a shoehorn on hand, and also requires bending over or using one's hands, making it difficult to put on the footwear smoothly. In order to solve this problem, various types of footwear have been developed in recent years that can be put on without using a shoehorn. Conventional footwear that can be put on without using a shoehorn is disclosed, for example, in Patent Document 1 below. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3238534 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional technique disclosed in Patent Document 1 has the advantage that shoes can be easily put on without the need for a separate shoehorn and without damaging the leather part of the shoe. However, the footwear shown in Patent Document 1 has a structure that connects the heel guide portion 400 to the insole 300, which means that the footwear tends to cause a foreign body sensation when and after putting on the footwear, resulting in a poor wearing comfort.

[0005] Therefore, the present invention aims to solve the problems of the above-mentioned conventional technology and to provide footwear that can be easily put on by inserting the foot into the footwear and putting weight on the heel, so that the foot can slide into the footwear without using a shoehorn or hands, and that is comfortable to wear, easy to put on, and has a lightweight counter. [Means for solving the problem]

[0006] In order to achieve the above object, the footwear of the present invention is a footwear having a counter in the heel portion that can assist the foot to slide into the footwear by inserting the foot into the footwear and putting weight on the heel portion of the footwear, the counter being made of a synthetic resin including a polyurethane resin, and having an inclined portion at the rear upper end that is inclined diagonally backward, and a plurality of openings arranged in line symmetry with respect to a vertical line passing through the top of the rear outer surface, and each of the plurality of openings being: Formed by multiple frames The counter has a plurality of through holes that are divided into a plurality of opening areas via a boundary frame, and the thickness of the boundary frame of the opening that is arranged on a vertical line that passes through the top of the rear outer surface of the counter is made thicker than the thickness of the boundary frame of the other openings other than the opening. The shape of the frame is formed by a pair of frames arranged in parallel on the left and right and extending in the vertical direction, and a pair of frames arranged in parallel on the top and bottom and extending in the horizontal direction connecting the pair of frames extending in the vertical direction. By making it roughly H-shaped The center line of the substantially H-shaped boundary frame is close to the inclination angle of the vertical line passing through the top of the rear outer surface of the counter. The boundary frame is provided for the other openings other than the opening. Regarding the above, the configuration is such that none of the frames that form the boundary frame extend in the vertical direction. As a result, the volume of the boundary frame of the opening located on a vertical line passing through the top of the rear outer surface of the counter is made larger than the volume of the boundary frame of the other openings excluding the opening, thereby making the vertical rigidity of the opening located on a vertical line passing through the top of the rear outer surface of the counter higher than the vertical rigidity of the other openings excluding the opening. In addition, the footwear of the present invention is Counter on the outer surface of the heel This is the second characteristic. The footwear of the present invention is 1 In addition to the features of the heel A counter is built into The third characteristic is that 。 [Effects of the Invention]

[0007] According to the footwear described in claim 1, by placing weight on the heel, the load on the heel is distributed among the multiple openings, allowing the counter to sink in as a unit while maintaining a certain strength. This allows the footwear to be easily put on by simply sliding the foot into the footwear via the inclined portion without using a shoehorn or hands. Furthermore, by configuring the multiple openings with multiple through-holes that are divided into multiple opening areas via a boundary frame, the load on the heel can be distributed in stages among an even greater number of locations. This allows the counter to sink in slowly, making the footwear easy to put on. Furthermore, by providing a counter with a plurality of openings, the weight of the counter can be reduced. Furthermore, the strength of the opening located on the vertical line passing through the apex of the rear outer surface, which serves as the starting point for inserting the foot into the footwear and is the area that bears the greatest load when putting on the footwear, can be made stronger than the strength of the other openings. This makes it possible to firmly maintain the weight of the foot placed on the heel when putting on the footwear and reliably prevent the heel from collapsing. This results in a footwear that allows the foot to slide into the footwear more smoothly via the inclined portion.

[0008] According to the footwear of claim 2, the heel portion By providing a counter on the outer surface of the footwear, there is no foreign body sensation when putting on or after wearing the footwear, and it is comfortable to wear. Can be used as footwear 。

[0009] Also, Excellent design It can be footwear.

[0010] According to the footwear described in claim 3, 1 to In addition to the effects of the described configuration, By incorporating a counter in the heel part, the sponge inside the heel part can be inserted into the opening of the counter, making it difficult for the sponge to slip off. It can be footwear.

[0011] Ma In addition, the footwear can prevent the counter from falling off. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] Footwear according to embodiments of the present invention will be described below with reference to the accompanying drawings to aid in understanding the present invention. However, the following description does not limit the present invention as defined in the claims.

[0014] First, footwear 1 according to a first embodiment of the present invention will be described with reference to FIGS. Referring to FIG. 1( a ), footwear 1 according to a first embodiment of the present invention is a so-called sneaker that includes an upper 10 , a sole 20 , and a counter 30 . Furthermore, since the upper 10 and sole 20 are similar to the upper 10 and sole 20 that make up commonly used footwear, detailed explanations will be omitted below, and only the counter 30, which is an important component of the present invention, will be explained in detail below.

[0015] 1 to 3, footwear 1 according to the first embodiment of the present invention includes a counter 30 on the outer surface of heel portion 11 of upper 10. As shown in FIG. This counter 30 naturally has the role of maintaining the shape of the footwear 1, just like the counters that are provided in commonly used footwear, but in the present invention, it is intended to assist the foot 40 in sliding into the footwear 1 by inserting the foot 40 into the footwear 1 and placing weight on the heel portion 11 of the footwear 1.

[0016] As shown in FIG. 1(b), the counter 30 includes an opening 31, an inclined portion 32, a notched portion 33, and a fixed portion .

[0017] The opening 31 is intended to effectively distribute the load applied to the counter 30 and to make the counter 30 lighter. In this embodiment, as shown in Fig. 2(a), the plurality of openings 31 are arranged symmetrically with respect to a vertical line T passing through the top of the rear outer surface, which is the axis of symmetry. Here, the "top of the rear outer surface" refers to the outermost protruding part of the rear outer surface of the counter 30 when the counter 30, which is formed in a substantially U-shape in a plan view, is attached to the footwear 1. Specifically, the three openings 31 are arranged symmetrically with respect to a vertical line T passing through the top of the rear outer surface as the axis of symmetry. The openings 31 arranged on the vertical line T passing through the top of the rear outer surface are configured so that the vertical line T passes through their center in the left-right direction. In other words, the "plurality of openings" in the "plurality of openings arranged symmetrically with respect to a line" in this invention is a concept that also includes openings arranged on the vertical line T passing through the top of the rear outer surface. 1(b) and 2(a), each of the plurality of openings 31 is configured to have a plurality of through holes that are divided into a plurality of opening regions via a boundary frame F. Specifically, as shown in FIG. 1(b), for example, the opening 31 disposed on the right side of the counter 30 is configured to have three through holes, namely a first through hole K1, a second through hole K2, and a third through hole K3, that are divided into three opening regions consisting of a first opening region R1, a second opening region R2, and a third opening region R3 via the boundary frame F. The shape and number of the openings 31, the shape and number of the boundary frame F, and the shape and number of the opening area (through holes) are not limited to those of this embodiment, and can be changed as appropriate as long as multiple openings are arranged in line symmetry with the vertical line T passing through the top of the rear outer surface as the axis of symmetry. In addition, in this embodiment, a step D is provided around the periphery of the opening 31 so that each opening 31 can be clearly distinguished, but the step D is not necessarily required, and the configuration may also be such that the step D is not provided.

[0018] Furthermore, in this embodiment, the vertical rigidity of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 is made higher than the vertical rigidity of the other openings 31 other than the opening 31. Specifically, as shown in Figure 2(a), the volume of the boundary frame F of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 is made larger than the volume of the boundary frame F of the other openings 31 other than the opening 31, thereby making the vertical rigidity of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 higher than the vertical rigidity of the other openings 31 other than the opening 31. Of course, the configuration for making the vertical rigidity of the openings located on the vertical line T passing through the top of the rear outer surface of the counter 30 higher than the vertical rigidity of the other openings other than the openings is not limited to that of this embodiment, and other configurations may be used, for example, by changing the material.

[0019] In this embodiment, the following two configurations are provided to make the volume of the boundary frame F of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 larger than the volume of the boundary frame F of the other openings 31 other than the opening 31. First, the thickness of the boundary frame F of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 is made thicker than the thickness of the boundary frame F of the other openings 31 other than the opening 31. Second, the shape of the boundary frame F of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 is made approximately H-shaped, thereby making the angle of the boundary frame F closer to the vertical line T passing through the top of the rear outer surface of the counter 30, and the boundary frames F of the other openings 31 other than the opening 31 are arranged at an angle. Of course, the configuration for making the volume of the boundary frame F of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 larger than the volume of the boundary frame F of the other openings 31 other than the opening 31 is not limited to this configuration, and other configurations may also be used.

[0020] The inclined portion 32 serves as a starting point for assisting the foot 40 to slide into the footwear 1 by placing weight on the heel portion 11 of the footwear 1. In this embodiment, when the counter 30 is fixed to the upper 10, the fixing portion 34 shown by hatching in Figure 1(b) is inserted into the fabric that forms the upper 10 and becomes invisible, and the inclined portion 32 is formed by tilting the rear upper end portion of the upper fixing portion 34 diagonally backward. 1(b), in this embodiment, the shape of the counter 30 located directly below the inclined portion 32 is made to be a substantially V-shape by combining with the shape of the inclined portion 32. In other words, at the lower end position of the inclined portion 32, the counter 30 is made to be a shape that is recessed inward in a substantially U-shape. The length of the inclined portion 32 overlapping with the vertical line T shown in FIG. 2(a) is not limited to that of this embodiment and can be changed as appropriate, but is preferably about 1 cm to 2 cm.

[0021] The cutout portion 33 is intended to form a space for receiving the moving portion when the rear side of the counter 30 is pushed down and moved downward when the footwear 1 is put on. The shape and size of the notch 33 are not limited to those in this embodiment, but can be changed as appropriate.

[0022] The fixing portion 34 forms a so-called glue margin for fixing the counter 30 to the upper 10 and the sole 20 . In this embodiment, as partially shown in FIG. 1(b), fixing portions 34 are provided on all outer edges except for the notched portions 33. Although not shown, in the portion fixed to the upper 10, the fixing portion 34 is inserted into the fabric forming the upper 10, and the fixing portion 34 and the fabric forming the upper 10 are bonded together with an adhesive. In addition, in the portion fixed to the sole 20, the fixing portion 34 is inserted inside the sole 20, and the fixing portion 34 and the sole 20 are bonded together with an adhesive. The counter 30 according to this embodiment is made of a synthetic resin containing polyurethane resin. Of course, the material for forming the counter 30 is not limited to this configuration, but considering durability, flexibility, elasticity, etc., it is desirable to use a synthetic resin containing polyurethane resin. The opening 31, the inclined portion 32, the notched portion 33, and the fixed portion 34 can be formed by integrally molding the counter 30 using a mold, for example.

[0023] Next, with reference to Figs. 2(b) to 3(b), the actions taken when putting on footwear 1 according to the first embodiment of the present invention will be described. First, referring to FIG. 2(b), the foot is inserted into the footwear 1 and the weight is placed on the heel portion 11 of the footwear 1. As a result, as shown by the black arrows in Figure 3(a), the counter 30 is pushed downward and contracts by a certain amount. At this time, the applied load is dispersed and transmitted to each opening area (each through hole) forming each opening 31 via the boundary frame F of each opening 31, causing each opening area (each through hole) forming each opening 31 to contract by a certain amount. At the same time, the fixing portion 34 bonded to the sole 20 causes the entire counter 30 to sink by a certain amount in the direction of the notch 33 while maintaining its strength. Then, the foot 40 slides into the footwear 1 via the inclined portion 32 along with the weight of the person wearing the footwear 1 . Thereafter, when the foot 40 is completely inserted into the footwear 1, a restoring force indicated by the black arrows in Figure 3(b) acts on each opening area (each through hole) forming each contracted opening 31 and on the entire counter 30, causing the counter 30 to return to its original state. This completes the action of putting on footwear 1.

[0024] The footwear 1 according to the first embodiment of the present invention having such a configuration provides the following effects.

[0025] By providing the counter 30, when weight is placed on the heel 11, the load on the heel 11 is distributed to the multiple openings 31, and the counter 30 can be sunk as a unit while maintaining a certain strength. This makes it possible to make the footwear 1 easy to put on by simply sliding the foot 40 into the footwear 1 via the inclined portion 32 without using hands. Furthermore, by configuring the plurality of openings 31 with a plurality of through holes that are divided into a plurality of opening regions via the boundary frame F, the load on the heel part 11 can be dispersed in stages to an even greater number of locations. This allows the counter 30 to sink slowly while maintaining a certain degree of strength, making the footwear 1 easy to put on. What is important here is that the counter 30 is configured to maintain a certain degree of strength while gently sinking downward by a certain amount when the foot 40 is slid into the footwear 1 with weight placed on the heel 11. This is because if the entire counter 30 were to collapse and contract when the foot 40 is slid into the footwear 1 with weight placed on the heel 11, the foot 40 would not be able to slide into the footwear 1 together with the weight of the person wearing the footwear 1. Furthermore, by providing the counter 30 with a plurality of openings 31, the weight of the counter 30 can be reduced, resulting in footwear 1 that does not tire the wearer when walking.

[0026] Furthermore, by making the vertical rigidity of the opening 31 located on the vertical line T passing through the apex of the rear outer surface of the counter 30 higher than the vertical rigidity of the other openings 31, the opening 31, which serves as the starting point for inserting the foot 40 into the footwear 1 and on which the greatest load is applied when putting on the footwear 1, can be made stronger than the other openings 31. This makes it possible to firmly maintain the weight on the heel portion 11 when putting on the footwear 1 and reliably prevent the heel portion 11 from collapsing. This makes it possible to provide footwear 1 that allows the foot 40 to slide even more smoothly into the footwear 1 via the inclined portion 32.

[0027] In addition, by making the volume of the boundary frame F of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 larger than the volume of the boundary frame F of the other openings 31 other than the opening 31, the vertical rigidity of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter is made higher than the vertical rigidity of the other openings 31 other than the opening 31, thereby making it possible to partially change the rigidity of the counter 30 without partially changing the material of the counter 30. Furthermore, the volume of the boundary frame F of the opening 31 arranged on the vertical line T passing through the top of the rear outer surface of the counter 30 is configured to be larger than the volume of the boundary frame F of the other openings 31 other than the opening 31, by first making the thickness of the boundary frame F of the opening 31 arranged on the vertical line T passing through the top of the rear outer surface of the counter 30 thicker than the thickness of the boundary frame F of the other openings 31 other than the opening 31, and secondly making the thickness of the boundary frame F of the opening 31 arranged on the vertical line T passing through the top of the rear outer surface of the counter 30 thicker than the thickness of the boundary frame F of the other openings 31 other than the opening 31. By making the shape of the frame F approximately H-shaped, the arrangement angle of the boundary frame F is configured to be close to the vertical line T passing through the top of the rear outer surface of the counter 30, and by configuring the boundary frames F provided for the openings 31 other than the opening 31 to be arranged at an angle, it is possible, despite the simple configuration, to effectively make the volume of the boundary frame F provided for the openings 31 arranged on the vertical line T passing through the top of the rear outer surface of the counter 30 larger than the volume of the boundary frame F provided for the openings 31 other than the opening 31. Therefore, it is possible to obtain footwear 1 that can reduce costs.

[0028] Furthermore, by forming the counter from a synthetic resin containing polyurethane resin, it is possible to provide a counter 30 that can gradually sink when weight is placed on the heel portion 11, and can gradually return to its original shape after the foot 40 is placed inside the footwear 1. This allows the counter 30 to have flexibility and elasticity, making the footwear 1 easier to put on and providing durability.

[0029] Furthermore, by making the shape of the counter 30 located directly below the inclined portion 32 match the shape of the inclined portion 32 to form an approximately L-shape (the counter 30 is recessed inward in an approximately U-shape at the lower end of the inclined portion 32), footwear 1 can be easily put on using the inclined portion 32, and after putting on footwear 1, the heel is firmly fixed inside footwear 1 in the recessed portion, maintaining stability, making footwear 1 easy to walk in and difficult to slip off.

[0030] Furthermore, by providing the counter 30 on the outer surface of the heel portion 11, the footwear 1 does not feel foreign when or after wearing the footwear 1, making it possible to provide a comfortable fit. Additionally, the footwear 1 can be made to have a high level of design.

[0031] Next, a modified example of the counter 30 according to the first embodiment of the present invention will be described with reference to FIG. This modified example differs from the counter 30 attached to footwear 1 according to the first embodiment of the present invention described above in that the volume of the boundary frame F provided in the opening 31 arranged on the vertical line T passing through the top of the rear outer surface of the counter 30 is made larger than the volume of the boundary frame F provided in the other openings 31 other than the opening 31. Therefore, the same components and parts that perform the same functions as those in the counter 30 attached to footwear 1 according to the first embodiment of the present invention described above are given the same numbers and symbols, and detailed explanations thereof will be omitted below.

[0032] Referring to Figure 3(c), in this modified example, the boundary frame F provided for the opening 31 arranged on the vertical line T passing through the top of the rear outer surface of the counter 30 is a circular boundary frame F in the center that is thicker than the boundary frames F provided for the other openings 31, and a pair of L-shaped and inverted L-shaped boundary frames F that are thicker than the boundary frames F provided for the other openings 31 are connected to both the left and right sides of the circular boundary frame F in an axis of symmetry with the vertical line T passing through the top of the rear outer surface of the counter 30 as the axis of symmetry. By using this configuration, the volume of the boundary frame F of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 can be made larger than the volume of the boundary frame F of the other openings 31 other than the opening 31, thereby making the vertical rigidity of the opening 31 located on the vertical line T passing through the top of the rear outer surface of the counter 30 higher than the vertical rigidity of the other openings 31 other than the opening 31. Such a configuration is also within the scope of the present invention.

[0033] Next, footwear 2 according to a second embodiment of the present invention will be described with reference to FIGS. Footwear 2 according to the second embodiment of the present invention differs from footwear 1 according to the first embodiment of the present invention described above only in the structure and positioning of the counter. Therefore, the same components and parts that perform the same functions as those in footwear 1 according to the first embodiment of the present invention are given the same numbers and symbols, and detailed descriptions thereof will be omitted below. Furthermore, since the basic functions of counter 300 are the same as those of counter 30 in footwear 1 according to the first embodiment of the present invention described above, the following description will focus on the differences from counter 30 in footwear 1 according to the first embodiment of the present invention described above.

[0034] Referring to FIG. 4(a), footwear 2 according to the second embodiment of the present invention has a counter 300 built into heel portion 11. Specifically, as shown in Figure 5(b), a counter 300 is arranged between the inner fabric P of the upper 10 and the sponge S1 arranged on the outer side thereof, and the outer fabric Q and the sponge S2 arranged on the inner side thereof. As shown in FIG. 4(b), this counter 300 is made up of an opening 310, an inclined portion 320, a notched portion 330, and a fixed portion 340. The cutout portion 330 differs only in shape and size from the cutout portion 33 of the counter 30 of the footwear 1 according to the first embodiment of the present invention described above, but has the same function, so detailed explanation will be omitted below.

[0035] As shown in Figures 4(b) and 5(a), the openings 310 are arranged in line symmetry with respect to the vertical line T passing through the top of the rear outer surface, similar to the counter 30 of the footwear 1 according to the first embodiment. Specifically, nine openings 310 are arranged in line symmetry with respect to the vertical line T passing through the top of the rear outer surface. Note that the openings 310 arranged on the vertical line T passing through the top of the rear outer surface are configured so that the vertical line T passes through their center in the left-right direction.

[0036] 4(b) and 5(a), each of the multiple openings 310 is configured to have multiple through holes that are divided into multiple opening regions via a boundary frame F. Specifically, as shown in FIG. 4(b), for example, one of the openings 310 located on the right side of the counter 300 is configured to have four through holes, namely a fourth through hole K4, a fifth through hole K5, a sixth through hole K6, and a seventh through hole K7, that are divided into four opening regions consisting of a fourth opening region R4, a fifth opening region R5, a sixth opening region R6, and a seventh opening region R7 via the boundary frame F.

[0037] In addition, by making the volume of the boundary frame F of the opening 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 larger than the volume of the boundary frame F of the other openings 310 other than the opening 310, the vertical rigidity of the opening 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 is made higher than the vertical rigidity of the other openings 310 other than the opening 310. In this embodiment, the following two configurations are provided to make the volume of the boundary frame F of the opening 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 larger than the volume of the boundary frame F of the other openings 310 other than the opening 310. First, the boundary frame F of the opening 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 is composed of two frames intersecting in an X shape, and the boundary frame F of the other openings 310 other than the opening 310 is composed of a single frame. Second, the vertical spacing of the multiple openings 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 is wider than the vertical spacing of the multiple openings 310 other than the opening 310. Of course, the configuration for making the volume of the boundary frame F of the opening 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 larger than the volume of the boundary frame F of the other openings 310 other than the opening 310 is not limited to this configuration, and other configurations may also be used.

[0038] As shown in Figures 4(b) and 5(a), similar to the counter 30 of the footwear 1 according to the first embodiment, the counter 300 has an inclined portion 320 at the upper rear end thereof that is inclined diagonally rearward. In this embodiment, the rear upper end portion of the counter 300 is inclined obliquely rearward to form the inclined portion 320 . 4(b), in this embodiment, like the counter 30 of the footwear 1 according to the first embodiment, the shape of the counter 300 located directly below the inclined portion 320 is shaped to form a substantially V-shape by combining with the shape of the inclined portion 320. In other words, at the lower end position of the inclined portion 320, the counter 300 is shaped to be recessed inward in a substantially U-shape.

[0039] The fixing portion 340 forms a so-called glue margin for fixing the counter 300 to the sole 20 . In this embodiment, as shown in FIG. 5(a), a fixing portion 340 is provided on the outer edge on the lower side excluding the notched portion 330. Although not shown, the fixing part 340 is inserted inside the sole 20, and the fixing part 340 and the sole 20 are bonded together with an adhesive. The counter 300 according to this embodiment is made of a synthetic resin containing polyurethane resin. Of course, the material for the counter 300 is not limited to that of this embodiment, but considering durability, flexibility, elasticity, etc., it is desirable to use a synthetic resin containing polyurethane resin. Furthermore, the opening 310, the inclined portion 320, the notched portion 330, and the fixed portion 340 can be formed by integrally molding the counter 300 using a mold, for example.

[0040] The actions involved in putting on footwear 2 according to the second embodiment of the present invention are the same as those involved in putting on footwear 1 according to the first embodiment of the present invention described above, except that counter 300 is built into heel portion 11, and therefore detailed explanations will be omitted below.

[0041] The footwear 2 according to the second embodiment of the present invention configured as described above provides the following effects. In the following, we will omit descriptions of effects similar to those achieved by the footwear 1 according to the first embodiment of the present invention described above, and will only describe effects that are different from those achieved by the footwear 1 according to the first embodiment of the present invention described above.

[0042] As a configuration for making the volume of the boundary frame F of an opening 310 located on a vertical line T passing through the top of the rear outer surface of the counter 300 larger than the volume of the boundary frame F of the other openings 310 other than the opening 310, first, the boundary frame F of an opening 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 is composed of two frames intersecting in an X shape, and the boundary frame F of the other openings 310 other than the opening 310 is composed of a single frame, and second, the vertical spacing of the multiple openings 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 is made wider than the vertical spacing of the multiple openings 310 other than the opening 31, thereby making it possible to effectively make the volume of the boundary frame F of an opening 310 located on the vertical line T passing through the top of the rear outer surface of the counter 300 larger than the volume of the boundary frame F of the other openings 310 other than the opening 310. Therefore, the footwear 2 can be made cost-saving.

[0043] Furthermore, by incorporating the counter 300 in the heel portion 11, the sponges S1 and S2 contained in the heel portion 11 can be inserted into the opening 310 of the counter 300, making it possible to provide footwear 2 in which the sponges S1 and S2 are less likely to slip off. Also, it is possible to provide footwear 2 in which the counter 300 can be prevented from falling off.

[0044] Although the footwear 1 and footwear 2 according to the above-described embodiments are configured as sneakers, the footwear according to the present invention is not limited to sneakers and may be configured as other footwear. [Industrial Applicability]

[0045] According to the present invention, it is possible to easily put on footwear by inserting the foot into the footwear and placing weight on the heel, allowing the foot to slide into the footwear without using hands or a shoehorn.In addition, it is possible to provide footwear that is easy to put on and allows the counter to be made lighter, so it is useful in industrial fields related to footwear and has great industrial applicability.
