Obviously, the described embodiments are preferred embodiments of the invention and should not be considered as excluding other embodiments. Based on the embodiment of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

In the claims, the specification and the drawings, unless otherwise expressly limited, the terms "first," "second," or "third," etc. are used for distinguishing between different elements and not for describing a particular sequence.

In the claims, the specification and the drawings, unless otherwise expressly limited, all directional or positional relationships, such as those using the terms "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," "counterclockwise," and the like, are based on the directional or positional relationships illustrated in the drawings and are for the purpose of convenience in describing the invention and simplifying the description, but do not indicate or imply that the device or element so referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore are not to be construed as limiting the scope of the invention.

In the claims, the description and the drawings of the present application, unless otherwise expressly limited, the term "fixedly connected" or "fixedly connected" is used, which is to be understood broadly, that is, any connection mode without displacement relation or relative rotation relation between the two, that is, including non-detachably fixed connection, integrated connection and fixed connection through other devices or elements.

In the claims, the specification and the drawings, the terms "including", "comprising" and variations thereof, if used, are intended to be inclusive and not limiting.

Referring to fig. 1, 2 and 3, the structure of an embodiment of the insole provided by the present invention is shown, wherein the insole is formed by combining a breathable layer 11, a soft material layer 12 and a hard material layer 13 from top to bottom, and the shape of the insole is roughly divided into a front sole portion 21, an arch portion 22 and a rear root portion 23 in a conventional manner.

Specifically, the air-permeable layer 11 is an air-permeable mesh fabric, and is combined to the upper end surface of the soft material layer 12 by thermocompression bonding.

The soft material layer 12 is an ethylene-vinyl acetate copolymer, i.e., an EVA material, which has certain water resistance and corrosion resistance, and has the advantages of good rebound resilience and strong tensile strength, and has good cushioning and buffering properties, so as to provide a comfortable feel to the foot of a user. The EVA material used in this example had a density of 0.11g/cm3 and a resilience of 72%. The density range can be selected from 0.10g/cm3 to 0.12g/cm3, the rebound performance corresponds to the density range, and the selection standard can be determined according to different use scenes, for example, in the use scene needing higher rebound force, namely, higher density can be selected. It should be noted that the soft material layer 12 can also be other materials with better elasticity, such as TPE, TPV, TPU or TPEE, etc., and the selection of the ethylene-vinyl acetate copolymer is only a matter of this embodiment, which does not mean that the soft material layer 12 can only be made of ethylene-vinyl acetate copolymer.

The hard material layer 13 is made of hard nylon, such as nylon 6, nylon 66, nylon 610, etc., and it needs to have certain rigidity and deformation resistance to prevent the hard material layer 13 from deforming when being stressed, and also needs to have certain elasticity to prevent the hard material layer from breaking. The rigid layer 13 may be formed from other rigid plastics, but it should be noted that certain forming properties are required to facilitate the formation of the insole.

The lower end face of the soft material layer 12 is compounded on the upper end face of the hard material layer 13 through hot pressing or other similar processes, so that the final insole can be compounded by the three-layer structure.

Through hard material layer 13, can avoid the shoe-pad to cause aversion or deformation with the inside mutual extrusion of shoes when receiving the yawing force to can prevent that the user from slipping or damaging, soft material layer 12 and ventilative layer 11 can provide comparatively comfortable feel when using this shoe-pad for the user simultaneously.

In addition, the above-mentioned insole is further provided with a supporting side skirt 30 in a shape, the supporting side skirt 30 is formed by extending upward and rearward from the edge of the arch portion 22 of the insole in this embodiment, and further forms a side skirt structure at the other edge of the insole except for the half sole portion 21, and the supporting side skirt 30 preferably has a certain outward-inclined form to fit the shape of the user's sole.

Through this support side skirt 30, when the shoe-pad was placed inside the shoes, support side skirt 30 can laminate each other with the side of the inside of shoes to when the shoe-pad received the lateral application of force, to the inside application of force of shoes, support side skirt 30's setting can improve the lifting surface area of shoe-pad and the inside of shoes, further prevent that the shoe-pad from appearing shifting.

Of course, in other embodiments, the supporting side skirt 30 may be disposed only on two sides of the arch portion 22 of the insole, because the arch portion 22 of the insole is subjected to a larger force when the insole is applied with a lateral force, and the supporting side skirt 30 is disposed at this position to play a better role in preventing the insole from shifting.

Furthermore, the present invention also provides an embodiment of a shoe assembly comprising a shoe and an insole as shown in the above embodiments, wherein the insole can be fitted to the shoe, and the fitting here means that the insole can be placed in the shoe with the inner lining of the shoe and with the shape of the insole fitted.

It should be noted that the utility model provides an insole and shoes subassembly can be applied to professional sport field such as weightlifting shoes especially, through the function that prevents the side direction aversion that the insole provided, can protect the sportsman effectively, avoids the sportsman to lead to the achievement not good or appear the damage because of the insole aversion.

The description of the above specification and examples is intended to illustrate the scope of the invention, but is not intended to limit the scope of the invention. Modifications, equivalents and other improvements which may be made to the embodiments of the invention or to some of the technical features thereof by a person of ordinary skill in the art through logical analysis, reasoning or limited experimentation in light of the above teachings of the invention or the above embodiments are intended to be included within the scope of the invention.
