[0002] In order to reduce production costs and improve efficiency, except for some customized handmade shoes, most casual shoes are produced in a standardized manner. The shoes produced by this large-scale processing are generally standard sizes. Compared with the standardization of shoe size, even the two feet of the same person are inconsistent in length, fatness and thinness, and the differences between different people are even greater. Therefore, for most people, there is a certain deviation from the standard size shoes. The Chinese patent with publication number CN219679904U discloses a new type of shoe for anti-wear and anti-heel drop, discloses a heel setting groove, and installs a fixed block in the groove, and installs a relatively soft small pillow on the fixed block. For shoes that cannot be fully adapted, most people will choose a size larger than their own foot shape. This structure is adapted by adding a soft structure between the inner cavity of the shoe and the gap between the foot. The disadvantage is that this structure is of fixed size and cannot be continuously adjusted according to different people. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] Reference Figures 1 to 5 As shown, the utility model is a casual shoe with an inflatable adjustable upper, comprising a sole 1 and an upper 2, wherein the upper 2 comprises an inner lining 3 and an upper airbag 4, wherein the upper airbag 4 is arranged on the inner side of the inner lining 3, wherein the inner side of the inner lining 3 refers to the side of the inner lining 3 facing the surface layer, and at least the matching part of the inner lining 3 and the upper airbag 4 is made of elastic material, and the upper airbag 4 is used to fill gas to expand toward the inner cavity of the shoe and drive the inner lining 3 to converge toward the foot. The above-mentioned sole 1 can be a polyurethane sole, a rubber sole, etc., the upper 2 comprises an inner lining 3 and a surface layer, wherein the surface layer is made of ordinary upper material, and the inner lining 3 or the part close to the airbag is made of a material with a certain elasticity, such as stretch fabric, etc. Figure 3 As shown, the upper airbag 4 adopts a flat structure, such as a sheet or strip structure. Figure 1 As shown, the upper airbag 4 can be arranged on the rear upper 201 and the front upper 204 of the upper surface 2. By inflating the upper airbag 4, the upper airbag 4 expands toward one side of the shoe cavity, fills the local gap between the foot and the shoe lining 3, and improves the fit between the lining 3 and the foot. The upper airbags at the front of the front upper 204 and the rear of the rear upper 201 can adjust the deviation between the foot and the inner cavity of the shoe of the standard size in the length direction by adjusting the degree of expansion. The upper airbags 4 on both sides of the rear upper 201 and the front upper 204 can adjust the gap between the foot and the inner cavity of the standard size shoe in the width direction of the foot. The size of the instep 203 is adjusted by the shoelaces. The shoe cavity is adjusted by the above structure to improve the wrapping of the shoe. The above embodiment is mainly used for casual shoes. Casual shoes are mainly used to provide a comfortable wearing experience, and the requirements for upper shaping are relatively lower than those for business shoes. Figure 2As shown, the adjustment structure composed of the tongue 5 and the shoelaces on the instep 203 is replaced by the upper airbag 4, and the adaptation of the instep 203 to the foot is achieved by inflating the upper airbag 4 and adjusting its expansion degree. The manufacturing method of the upper airbag 4 can refer to the existing technology, such as the TPU upper airbag and its preparation method disclosed in publication number CN117137229A. The upper airbag 4 has sealing properties. The upper airbag 4 is set between the surface layer and the inner lining 3, which will affect the air permeability of the upper 2 to a certain extent. An improved method is to set a Figure 4 , Figure 5 The buffer airbag 6 shown in the figure is provided with a similar reserved hole 7, which passes through the upper airbag 4 and is surrounded by the airbag wall. However, the airbag structure of this method is relatively complex and the cost is relatively high. Another improved method is to refer to Figure 1 and Figure 2 As shown, the upper airbag 4 of the front upper 204 is changed to be arranged on the toe 205 and the upper feet on both sides of the toe 205, and the shoe waist 202 and the front upper 204 reserve a breathable area 10, and the breathable area 10 can be formed of a mesh structure using non-woven materials, which has excellent breathability, thereby reducing the influence of the upper airbag 4 on the breathability. Different upper airbags 4 can be inflated independently with independent inflatable structures, or they can be inflated as a whole. In one embodiment, the upper airbag 4 is connected to the air pipe, and the air pipe is buried on the inner side of the lining, the air pipe is connected to the sole 1, and the air pipe is also connected to the cushioning airbag 6. The cushioning airbag 6 is connected to the air inlet on the side of the sole 1 through the air pipe 11. The gas is filled into the upper airbag 4 and the cushioning airbag 6 through the air inlet using the balloon 8. The air inlet can be set as a whole (referring to inflating the cushioning airbag and the upper airbag in the shoe through the inflation port) for inflation, or multiple air inlets can be set, independently connected to the corresponding upper airbag 4 or cushioning airbag 6 for independent inflation, and a control air valve can be set on the air pipe of the air inlet for exhaust.

[0024] In the above embodiment, referring to Figure 4 As shown, the sole 1 is also provided with a groove, in which a cushioning airbag 6 is provided. The cushioning airbag 6 extends from the forefoot part of the sole 1 to the heel part to form a full-palm airbag. The cushioning airbag 6 is connected to the trachea 11, and the trachea 11 is connected to the air inlet provided on the side of the sole 1 for inflating the cushioning airbag 6 and making the cushioning airbag 6 expand toward the shoe cavity. An elastic pad is provided above the cushioning airbag 6. A control valve is provided at the air inlet. The cushioning airbag 6 of this embodiment can adjust the height of the insole or the pad, which not only achieves a good cushioning and shock-absorbing effect, but also improves the wrapping of the sole, the instep and the shoe cavity, and improves comfort. In order to improve the ventilation effect of the sole 1, a reserved hole 7 can be provided on the airbag to cooperate with the exhaust channel provided on the sole 1 for ventilation. When the ventilation structure is not provided on the upper 2 (such as winter warm shoes), a ventilation channel can be established in the full-palm airbag so that the inner cavity of the shoe can be ventilated through the sole 1.

[0025] In the above embodiment, referring to Figure 5 As shown, the cushioning airbag 6 includes a sheet-like forefoot airbag 601, a ring-shaped or U-shaped heel airbag 602 arranged at the heel, and a ball 8 is arranged at a reserved position in the middle of the heel airbag 602. The ball 8 is connected to the cushioning airbag 6 through an air tube 11. The cushioning airbag 6 and the upper airbag 4 are inflated by stepping on the ball with the heel. In this embodiment, when the upper surface of the heel airbag 602 is higher than the ball, the heel airbag 602 supports the pressure applied by the heel, and the heel is no longer inflated when walking or stepping on the heel. Of course, in order to avoid the ball 8 constantly inflating the airbag when walking, so that the airbag cannot be expanded to a predetermined degree, a hard cover can be set at the rear of the heel, and the cover is taken out when inflating. When the airbag is inflated to the expected degree, the cover is used to protect the ball to avoid being stepped on. Figure 5 Another specific embodiment is shown, that is, a one-way control valve 9 is provided on the air pipe of the balloon 8, and the one-way control valve 9 is provided in the side groove of the sole 1. The one-way control valve 9 controls the on-off of the air intake of the cushioning airbag 6 or the upper airbag 4. The height of the heel airbag 602 expansion is greater than the height of the balloon 8. The balloon 8 inflates the cushioning airbag 6 and / or the upper airbag 4 by stepping on the balloon 8 with the heel. The one-way control valve 9 can be a series structure of a one-way valve and a control air valve, with one-way air intake and can control the on-off of the air pipe. In this embodiment, when the inflation reaches the expected degree, the one-way control valve 9 is closed, and the balloon 8 is equivalent to a cushion, and will not continue to inflate the cushioning airbag 6 and the upper airbag 4. The cushioning airbag 6 and the upper airbag 4 can be connected to the air outlet for discharging excess gas.
