However, while certain specific embodiments are specifically illustrated herein, these embodiments are merely exemplary and are not to be considered in all respects as limiting or exhaustive. Thus, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and principles of the invention.

Therefore, according to an embodiment of the present invention, the foaming base material 200 'includes a plurality of semi-foaming particles 205' that can be directly heated to foam upon being microwaved or that can be foamed by a temperature increase caused by other adjacently disposed materials being heated. For example, the semi-foamed particles 205 'in the foamed base material 200' may be a high loss material that can be foamed by microwave heating. Alternatively, in the case where the semi-foamed particles 205 ' are materials that are difficult to heat by microwaves, an additive that easily absorbs microwaves (e.g., Al2O 3-SiC) may be further added to the foaming base material 200 ', so that the semi-foamed particles 205 ' can be foamed by the temperature increase caused by heating due to the absorption of microwaves by the surrounding additive.
According to some embodiments of the present invention, the semi-foamed particles 205' may be made of Polyurethane (PU), Thermoplastic Polyurethane (TPU), or thermoplastic elastomer (TPE), and may be particles having a certain size formed after being foamed to a certain extent and having foaming ability. Specifically, the semi-foamed particles 205' can be made of Polyurethane (PU), Thermoplastic Polyurethane (TPU) or thermoplastic elastomer (TPE) material by molding, adding a foaming agent, mixing, and foaming incompletely, and still have foaming ability. For example, the semi-foamed particles 205' may be formed by semi-foaming a foamed thermoplastic polyurethane (i.e., a foamed Thermoplastic Polyurethane (TPU)). However, the present invention is not limited thereto, and the semi-expanded particles 205' may be particles prepared by any means that are expanded to some extent to have a particle shape and still maintain the ability to be expanded.

As described above, since the method of manufacturing a shoe body structure and the manufactured shoe body structure according to the present invention are related to manufacturing a shoe, according to other embodiments of the present invention, other portions of the shoe body structure may be further manufactured while completing a foamed molded body (e.g., a foamed molded body as an insole). Therefore, the process can be further simplified and the preparation time or cost can be reduced.
For example, before the foaming step S200, besides the interlayer of the upper 900 or between the

As described above, as shown in fig. 8A and 8B, before the foaming step S200, a
According to some embodiments of the present invention, in order to form the foam molding body manufactured according to various embodiments of the present invention and to smoothly adhere to the upper 900, the upper 900 may include PU, TPU, or TPE, which may not foam or have negligible foaming capacity. For example, upper 900 may be woven from yarns of PU, TPU, or TPE. However, the present invention is not limited thereto, as long as it can be bonded to the foamed molded articles of the respective examples.
In addition, although not shown in the drawings, according to another embodiment of the present invention, an outsole material or an outsole may be laid on the
According to some embodiments of the present invention, in order to allow the shoe body part (e.g., the foamed molded body 400) to be formed while being more smoothly adhered to the outsole or outsole material, the outsole or outsole material may include PU, TPU, or TPE, which does not foam or has negligible foaming ability. However, the present invention is not limited thereto, as long as it can be bonded to a shoe body part (e.g., the foamed molded body 400).
Next, another embodiment in which the foaming base material 200' is provided and foamed in a microwave manner according to the present invention will be described below with reference to fig. 10A and 10B.
In detail, referring to fig. 10A, according to an embodiment of the present invention, the difference from the embodiment shown in fig. 2A to 3 is that a plurality of first granules 210 'having a first particle size range and a plurality of second granules 220' having a second particle size range may be respectively placed in different blocks r1, r2 and r3 in the setting step S100. That is, the semi-foamed particles 205 'of the foamed base material 200' may comprise: a plurality of first particles 210 'having a first particle size range and a plurality of second particles 220' having a second particle size range, and the first particles 210 'and the second particles 220' may be separately disposed in different blocks.
In view of the foregoing, according to some embodiments, the median value of the first particle size range is substantially greater than the median value of the second particle size range. That is, the first particles 210 'are substantially larger than the second particles 220'. In a preferred embodiment, the middle of the first particle size range is substantially equal to the average particle size of the first particles 210 ', and the middle of the second particle size range is substantially equal to the average particle size of the second particles 220'. However, due to process tolerances and the like, there may be a difference in particle size between the plurality of first particles 210 'or between the plurality of second particles 220', and the average particle size thereof is not necessarily equal to the intermediate value.
As described above, the first particles 210 'and the second particles 220' having different sizes may be respectively disposed in different regions. For example, three blocks r1, r2, and r3 may be disposed between upper 900 and last 800 in a section B-B ' taken along shoe length direction SL along

In summary, according to some embodiments of the present invention, the inlay element 600' may comprise a chip, a metal sheet, or any object made of a material that is not polar and can not be heated by microwave or other materials that can not be affected by microwave, and can be used as an ornament or a functional component in the shoe body structure 6000. For example, according to some embodiments of the present invention, inlay element 600' may be a GPS track wafer. Thus, the real-time tracking of the athletic contestant or the disabled person wearing the shoe body structure can be tracked. Alternatively, the inlay element 600' may be a chip for measuring blood pressure, body fat or for recording steps, and may be used to detect the health state or exercise state of the wearer. However, the above is merely an example, and the present invention is not limited thereto.

In summary, according to an embodiment of the present invention, the waterproof moisture-permeable film may include or may be made of a material that can be heated by microwave, and may include a material having properties similar to those of the semi-foamed particles 205', for example. For example, the waterproof moisture-permeable film may comprise Polyurethane (PU), Thermoplastic Polyurethane (TPU), or thermoplastic elastomer (TPE), which are not foamed or have negligible foaming ability. As described above, before the foaming step S200, at least a portion of the foaming base material 200 '(e.g., at least a portion of the semi-foamed particles 205') may be further coated with a waterproof moisture-permeable film. Therefore, since the material of the semi-foamed particles 205' has commonality, the waterproof moisture-permeable film can be welded or coated and fixed to at least a part of the surface of the formed foamed molded body after the foaming step S200. That is, at least a portion of the foamed molded body can be insulated or covered by the waterproof moisture-permeable film that substantially maintains the original properties or the original structure and is welded to each other, thereby improving the waterproof moisture-permeable ability of the formed foamed molded body and at least a portion of the shoe body structure including the foamed molded body welded to the upper 900.

In summary, according to the embodiments of the present invention, the foamed molded body welded to the upper and the shoe body structure including the foamed molded body can be completed by the microwave heating process with relatively cheap and simple installation conditions in an integrated process. In detail, compared to the conventional injection molding process, the microwave heating process performed according to the embodiments of the present invention can shorten the process time and save energy because it is not necessary to melt the base material at a high temperature, thereby greatly reducing the production cost. Furthermore, microwave heating enables the heating object to generate heat from the inside to the whole body in a short time, compared with the known mode of heating from the outside to the inside, the heating is faster and uniform, so that the homogeneity of the finally produced product can be improved, and the microstructure is not easy to damage and can be kept with the optimized microstructure and the corresponding functional properties. Therefore, the performance and yield of the manufactured product can be improved, and the prepared foam forming body and the shoe body structure can have the required poly-meaning structure, shape or property. Therefore, the applicability and applicability of the foam molded body and the shoe body structure can be improved or improved.
