1. A shoe is mounted on a shoe comprising a shoe body that accommodates a user's foot, a shoe sole disposed on the inner bottom surface of the shoe body and in contact with the user's foot, and a heel disposed on the rear of the shoe body that contacts the ground and supports the user's load. The above shoe sole includes an upper fabric formed in the shape of a user's foot and a lower fabric positioned below the fabric, and An airbag interposed between the upper fabric and the lower fabric, having a shape in which the thickness continuously decreases as it moves from the user's heel toward the toes; An air inlet connected to the airbag and configured to allow air to flow in; and Height-adjustable shoes including a check valve that prevents the air from leaking out of the airbag.
2. In paragraph 1, The above airbag comprises an upper plate, a lower plate facing the upper plate, and a side plate connecting the upper plate and the lower plate, and the side plate has a plurality of creases formed therein to change the height, making it a height-adjustable shoe.
3. In paragraph 2, A height-adjustable shoe in which the upper plate of the airbag is attached to the upper fabric and the lower plate is attached to the lower fabric.
4. In paragraph 1, The above airbag is a height-adjustable shoe formed from a stretchable synthetic resin material.

Description

height-adjustable shoes The present invention relates to a height-adjustable shoe. Generally, shoes such as sneakers and dress shoes are worn by users to protect their feet when going out, and recently, shoes with various added functions are being released. Recently, technology to adjust the height of shoes has been developed. In Public Utility Model 20-2016-0003086, a height-adjustable member that allows for easy height adjustment of the front and rear parts of a shoe and the shoe thereof (Date of publication: September 13, 2016), a technology has been disclosed in which a height-adjustable member that allows for easy height adjustment is installed on the front and rear parts of a shoe so that the wearer's foot can be level when walking on a path formed by an uphill or downhill slope of a certain angle. However, the aforementioned published utility model 20-2016-0003086 discloses a technology for adjusting the height of a shoe so that the wearer's foot can be level on an inclined road, but it does not include a technology for adjusting the height of the shoe on a road with little incline or on flat ground. FIG. 1 is a cross-sectional view of a height-adjustable shoe according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the shoe sole and height adjustment unit of FIG. 1. Figure 3 is a perspective view of the height adjustment unit of Figure 1. Figure 4 is a cross-sectional view illustrating the height of the height-adjustable shoe of Figure 1 increased. The present invention described below is capable of various modifications and may have various embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. In describing the invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions may obscure the essence of the invention. The terms used in this patent are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this patent, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Additionally, terms such as "first," "second," etc., may be used to distinguish and describe various components, but said components shall not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. In addition, if at least two different embodiments are described in this patent, each embodiment may use all or part of its components in combination and mixed with one another without further description, as long as it does not deviate from the technical concept of the present invention. FIG. 1 is a cross-sectional view of a height-adjustable shoe according to an embodiment of the present invention. FIG. 2 is an exploded perspective view showing the shoe sole and height adjustment unit of FIG. 1. FIG. 3 is a perspective view showing the height adjustment unit of FIG. 1. FIG. 4 is a cross-sectional view showing the height of the height-adjustable shoe of FIG. 1 increased. Referring to FIGS. 1 to 4, the height-adjustable shoe (100) includes a shoe body (110), a shoe sole (120), a height adjustment unit (130), a gas inlet (140), and a plug (150). The shoe body (110) includes a sole (112), a shoe cover (114), and a heel (116). The sole (112) is formed in a shape similar to the user's foot shape, can be formed in a thick plate shape, and can be made of synthetic resin material. The shoe cover (114) covers the sole (112) and is formed in a shape that covers the top of the user's foot, and the shoe cover (114) can be made of various materials such as leather, fabric, and synthetic resin. The heel (116) is positioned at the rear of the sole (112) in contact with the ground, and the heel (116) serves to support and distribute the user's load. The shoe sole (120) is positioned inside the shoe body (110) and on the upper surface of the sole (112). The shoe sole (120) comes into contact with the user's foot, allowing the user to feel a cushioning sensation. Referring to FIG. 2, the shoe sole (120) includes an upper fabric (122) formed in a shape similar to the user's foot shape and a lower fabric (124) positioned below the upper fabric (122) and having a shape similar to the user's foot shape.
