Problems solved by technology

[0008] The technical problem to be solved by the present invention is: the midsole of the existing high-heeled shoes adopts the technical problems of steel bar structure complicated preparation process, poor comfort, etc.
Now we provide a steel strip-free midsole, which divides the midsole structure into a front midsole and a rear midsole. The materials of the front midsole and the rear midsole are different. In the case of achieving the same hardness, no steel strip structure is used to solve the problem. Technical problems such as poor wearing comfort of the midsole of existing high-heeled shoes are solved

Embodiment 1

[0032] Such as Figure 1-Figure 3 As shown, a high-heeled midsole free of steel bars includes a front midsole 1 and a rear midsole 2, both of which are arc-shaped planes; the arc-shaped plane of the rear midsole 2 gradually extends upwards , the extended part is the middle part and the heel of the rear midsole 2.

[0033] In this embodiment, the entire midsole structure is divided into a front midsole 1 and a rear midsole 2. It is mainly considered that the midsole structure of high-heeled shoes in the prior art is an integrated structure, and the materials used are the same. During walking, the forefoot is close to the steel bar structure, and the comfort is poor.

Embodiment 2

[0035] On the basis of Example 1, this embodiment defines that the front midsole 1 is made of EVA material,

[0036] The front midsole 1 made of EVA material in this embodiment has good flexibility and strong shock absorption performance, and is quite comfortable when women wear it. Especially in the process of walking, the forefoot is firmly attached to the area where the front midsole 1 is located, and because the thickness of the front sole of the shoe itself is relatively low, the front midsole 1 made of EVA material is easy to use.

Embodiment 3

[0038] In this embodiment, on the basis of the foregoing embodiments, the rear midsole 2 is further limited to be made of PU material. The PU material is a known material, and the rear midsole 2 made by it has a certain hardness and is not easy to be corroded or damaged by other materials. External force and other damage, has a strong mechanical properties.

[0039] Therefore adopt rear midsole 2 that PU material is made, and it is positioned at the middle part or heel of footwear, can carry body weight.

Abstract

The invention discloses a steel-bar-free high-heeled shoe insole. The steel-bar-free high-heeled shoe insole comprises a front insole body and a rear insole body. The front insole body and the rear insole body are arc-shaped planes. The arc-shaped plane of the rear insole body gradually extends upwards, and the extending part is the middle portion of and the heel part the rear insole body. According to the steel-bar-free high-heeled shoe insole, the front insole body and the rear insole body are of an integral structure at the high temperature, the front insole body is made of a flexible EVA material with high vibration reducing performance, and the rear insole body is made of a PU material with a certain thickness and hardness. The comfort of the half sole area of a high-heeled shoe is guaranteed, and it is also guaranteed that an insole structure of the high-heeled shoe has a certain hardness and high bearing force.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to a steel bar-free high-heeled shoe midsole and a manufacturing method thereof. Background technique [0002] The sole of fashion women's shoes is composed of three parts: the outsole or the outsole that is in direct contact with the ground, the midsole located in the middle of the bottom of the shoe, and the insole that is in direct contact with the foot of the walker. [0003] Fashion women's shoes require the midsole to have a certain hardness, which can play a good role in supporting the soles of the feet. At the same time, it also requires the midsole to have high folding resistance, wear resistance, and is not easy to be broken. [0004] In the fashion women's shoes industry, the midsoles of women's shoes are usually made of high-density cardboard. This kind of cardboard is characterized by low hardness, poor support, and is not resistant to folding. There is a break in t...
