Problems solved by technology

[0002] The fat and thin human feet can be divided into type 4, type 3 and a half, type 3, type 2 and a half, and type 2. However, shoes can only be made according to one type of foot shape. Therefore, there are fat shoes with thin feet in wearing, and the empty cavity of the shoes will cause discomfort to the feet, which affects people's health, or fat feet can be worn in thin shoes. , foot compression can also cause discomfort

Embodiment Construction

[0012] A foot type adjusting insole, such as figure 1 As shown, the insole body 1 is included, the insole body 1 is connected with a plantar circumference adjustment device 2 and a tarsal circumference adjustment device 3, and the plantar circumference adjustment device 2 has one on both sides of the insole, and the plantar circumference adjustment device 2 and the tarsal circumference adjustment device The circumference adjustment device 3 is composed of two polyurethane polymer layers 4 and a nickel-titanium alloy material layer 5 filled in the middle of the two layers, which is combined with the insole by gluing or injection.

[0013] The shoe adopts a fat shape during the production process, and the design of the insole sets the space in the shoe cavity to a thin shape, that is, the original size of the circumference is reduced. When the foot enters the shoe cavity, it is compressed by the foot. The circumference of the insole is adjusted. When the circumference of the foo...

Abstract

The invention provides a foot shape adjusting type shoe pad, comprising a shoe pad body, wherein plantar circumference adjusting devices and a tarsal circumference adjusting device are connected onto the shoe pad body; the plantar circumference adjusting devices and the tarsal circumference adjusting device are respectively composed of two layers of polyurethane high-molecular polymers and a nickel titanium alloy material layer filling between the two layers. According to the shoe pad, as the plantar circumference adjusting devices and the tarsal circumference adjusting device are designed for two parts, the shoe pad can adapt to foot shape change when being put on so as to realize adjustment; compared with an existing adjusting type shoe pad, the shoe pad has the advantages of keeping an initial state quite well, not being ineffective due to time and persistently-strengthened pressure, and keeping the space of a shoe cavity quite well.

Description

technical field [0001] The invention relates to the field of insoles, in particular to a foot shape-adjustable insole. Background technique [0002] The fat and thin human feet can be divided into type 4, type 3 and a half, type 3, type 2 and a half, and type 2. However, shoes can only be made according to one type of foot shape. Therefore, there are fat shoes with thin feet in wearing, and the empty cavity of the shoes will cause discomfort to the feet, which affects people's health, or fat feet can be worn in thin shoes. , foot compression can also cause discomfort. Contents of the invention [0003] Purpose of the present invention is exactly to provide a kind of foot shape adjusting type insole in order to solve the deficiencies in the prior art. [0004] The purpose of the present invention is achieved with the following technical solutions: [0005] A foot shape-adjusting insole, comprising an insole body, on which a plantar circumference adjustment device and a t...
