Description

Insoles and variable-shaped shoes to which they are applied

[0001] The present invention relates to an insole formed to be adjustable in width and a variable shoe to which the insole is applied so that the width can be adjusted according to the user's intention.

[0002] Conventional shoes are standardized and produced based on average foot size. They are uniformly manufactured based on average foot size measured by age and gender.

[0003] Shoes like these fall short in satisfying the diverse needs of consumers. Human feet are not uniformly standardized, and their sizes and shapes vary greatly from person to person. However, ready-made shoes are manufactured based on average foot sizes and shapes. This prevents them from providing a perfect fit for each individual, ultimately failing to provide sufficient satisfaction to the wearer.

[0004] The purpose of the present invention is to provide an insole and a shoe to which the insole is applied, the width of which can be adjusted according to the wearer's intention, thereby increasing the wearer's satisfaction by allowing the wearer to adjust the width to fit his or her foot at the time of need.

[0005] The present invention proposes an insole that is installed and used inside a shoe, including a left insole and a right insole, and is formed so that a portion of the left insole and the right insole overlap each other so that the width can be adjusted by adjusting the degree to which the left insole and the right insole overlap each other, and a variable shoe to which such an insole is applied, thereby achieving the above-mentioned object.

[0006] According to the present invention, a wearer can adjust the width of the shoe to fit the shape of his or her foot, thereby providing a shoe that provides optimal fit and thus increases satisfaction.

[0013] The present invention proposes an insole that is installed and used inside a shoe, including a left insole and a right insole, and is formed so that a portion of the left insole and the right insole overlap each other so that the width can be adjusted by adjusting the degree to which the left insole and the right insole overlap, and a variable shoe to which such an insole is applied.

[0014] Hereinafter, the present invention will be described in detail with reference to the attached drawings, FIGS. 1 to 7.

[0015] Fig. 1 is an exemplary drawing showing an insole according to the present invention, and Fig. 2 is an exemplary drawing showing a state in which the width of the insole according to the present invention is adjusted.

[0016] The insole (300) according to the present invention is formed so as to be able to adjust its width. To this end, the insole (300) is formed to include a left insole (320) and a right insole (340).

[0017] The left insole (320) and the right insole (340) have a structure similar to that of the insole (300) split lengthwise. In this configuration, the left insole (320) and the right insole (340) are formed so that some parts overlap each other. Part of the left insole (320) and the right insole (340) overlap each other at the center of the insole (300).

[0018] Meanwhile, it is preferable that the point where the left insole (320) and the right insole (340) overlap be formed thinner toward the end. Accordingly, even if the left insole (320) and the right insole (340) overlap, there is no significant effect on the overall thickness of the insole (300).

[0019] According to the above, the width of the insole (300) can be adjusted by adjusting the degree to which the left insole (320) and the right insole (340) are overlapped. Consequently, it is possible to implement an insole (300) whose width is adjusted according to the specifications of the shoe.

[0020] In the insole (300) formed as described above, the left insole (320) and the right insole (340) can be formed such that the heel portion is joined to each other. That is, the insole (300) according to the present invention is formed so that the width is adjustable only in the remaining portion except the heel portion. This structure is taken into consideration that, even if the size of a person's foot is the same, the ball size is different, so that shoes are formed or shoelaces are adjusted accordingly. That is, this is a structure adopted to secure structural stability by forming a structure in which the left insole (320) and the right insole (340) are joined to each other while allowing the width of the insole (300) according to the present invention to be adjusted only in the ball portion of the foot.

[0021] Fig. 3 is an exemplary view showing a variable shoe to which an insole according to the present invention is applied, and Fig. 4 is an exemplary cross-sectional view of a variable shoe to which an insole according to the present invention is applied.

[0022] The shoe is formed by connecting the upper (200) to the sole (100), and forming a structure on the upper (200) that can tie shoelaces. At this time, the sole (100) is formed of an elastic material. By mounting the insole (300) according to the present invention described above inside the shoe, a variable shoe whose width can be adjusted is formed. That is, when the width of the insole (300) according to the present invention mounted inside the shoe is adjusted and then the strength for tying the shoelaces is adjusted, the sole (100) contracts to match the width of the insole (300), thereby adjusting the width of the shoe to fit the wearer's foot perfectly.

[0023] Here, a concave groove (120) may be formed on the edge of the sole (100). The groove (120) is formed along the longitudinal direction of the sole (100), and may be formed particularly in the remaining portion excluding the heel portion. The groove (120) serves to allow the edge of the sole (100) to contract due to an external force, and the width of the sole (100) is adjusted by contracting the groove (120) depending on the degree to which the widths of the left insole (320) and the right insole (340) are narrowed. For example, if the width of the sole (100) is adjusted as described above while the width of the insole (300) is adjusted, the width of the shoe is adjusted.

[0024] Figures 5 and 6 are exemplary views showing a state in which the adjusting device is formed as a tightening strap in a variable shoe according to the present invention.

[0025] The width of the insole (300) can be adjusted by an adjustment device. The adjustment device can be formed by an adjustment dial (420) that is mounted so as to be visible on the outside of the upper and an adjustment string (440) that is wrapped around and released from the adjustment dial (420).

[0026] Here, the adjustment dial (420) can be adopted to be formed to be able to tighten the shoelaces, and is mounted so as to be exposed on the outside of the upper of the shoe.

[0027] The adjustment strap (440) is installed so that one end is connected to the adjustment dial (420), passes alternately along the edges of the left insole (320) and the right insole (340), and then the other end is connected again to the adjustment dial (420). A plurality of loops (360) are formed longitudinally on the edges of the left insole (320) and the right insole (340), so that the adjustment strap (440) passes through the loops (360). For example, when the adjustment dial (420) is formed on the heel side of the shoe, an adjustment string (440) connected at one end to the adjustment dial (420) passes through a ring (360) formed at the front of the left insole (320) and reaches a ring (360) formed at the front of the right insole (340), then changes direction and passes through a ring (360) formed at the back of the left insole (320) and then passes through a ring formed at the back of the right insole (340) and is connected at the other end to the adjustment dial (420).

[0028] According to the above, when the adjustment dial (420) is tightened, the adjustment string (440) is wound around the adjustment dial (420) while the adjustment dial (420) is supported on the upper, and accordingly, the left insole (320) and the right insole (340) are pulled in the width direction, and the degree of covering is adjusted, and the width of the insole (300) is adjusted.

[0029] Meanwhile, the adjustment dial (420) may be formed on the side of the shoe, in which case, it is natural that the degree to which the left insole (320) and the right insole (340) are covered should be adjusted by tightening and loosening the adjustment dial (420) by determining the arrangement of the adjustment string (440) according to the position of the adjustment dial (420).

[0030] Fig. 7 is an exemplary diagram showing a structure in which an adjusting device is formed of a bolt and a nut in a variable shoe according to the present invention.

[0031] The adjusting device can be formed by including a nut body (540) and a bolt body (520) that are installed across the sole (100) in the width direction and are fastened to each other.

[0032] The bolt body (520) is formed so that its head is exposed outside the shoe, and the nut body (540) is formed so that it is embedded in the sole, thereby fixing its position. Accordingly, when the bolt body (520) is tightened or loosened, the width of the sole (100) is adjusted, and at the same time, the degree to which the left insole (320) and the right insole (340) are overlapped is adjusted. In particular, when the shoelace is tightened, the upper (200) is pulled, and the width of the sole (100) is fixed in the adjusted position.
