Description

Technical Field

[0001] The utility model belongs to the technical field of insoles, and in particular relates to an insole adaptable to the arch of the foot. Background Art

[0002] The primary function of the human arch is to distribute gravity from the ankle joint through the talus forward to the metatarsal heads and backward to the calcaneus, ensuring stable support for the foot when standing upright. The elasticity of the arch muscles plays a crucial role in cushioning shock when jumping or falling from a height. During walking, especially long distances, the elasticity of the arch muscles buffers the rhythm between the downward force of gravity and the rebound force of the ground, while also protecting the blood vessels and nerves in the sole of the foot from compression.

[0003] The height and shape of the arch of the foot vary from person to person due to factors such as genetics, height, foot muscles, lifestyle, and environment. Existing shoes are manufactured using fixed molds and standardized production methods. These standardized shoes cannot adapt to different people's needs. This is because everyone's arch is different, and wearing shoes that don't adapt to the arch can cause varying degrees of pain or fatigue. Therefore, there is a need for an insole that can adapt to the arch of the foot. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide an insole that adapts to the arch of the foot, aiming to solve the problem that existing shoes do not adapt to the arch of the foot.

[0005] The embodiment of the present invention is implemented as follows: an insole that adapts to the arch of the foot, the insole that adapts to the arch of the foot comprises a main body layer and a support layer, and the support layer is arranged at the arch of the foot of the main body layer.

[0006] Preferably, a support sheet is provided between the main body layer and the support layer, and the support sheet is provided on both inner and outer sides of the arch of the main body layer.

[0007] Preferably, a support sheet is provided between the main body layer and the support layer, and the support sheet is provided on the inner side of the arch of the main body layer.

[0008] Preferably, a support sheet is provided between the main body layer and the support layer, and the support sheet is provided on the outer side of the arch of the main body layer.

[0009] Preferably, a plurality of openings are provided on both the inner and outer sides of the support layer.

[0010] Preferably, the shape of the opening is rectangular or triangular.

[0011] Preferably, a plurality of pressure protrusions are provided on the support layer.

[0012] Preferably, the insole adaptable to the arch of the foot further comprises a fabric layer, and the fabric layer is arranged above the main body layer.

[0013] An embodiment of the present invention provides an arch-adaptive insole, in which a support layer is provided at the arch of the foot on a main body layer. The function of the support layer is to provide support for the arch of the foot to adapt to various conditions and relieve fatigue or pain caused by unsuitable shoes.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] As shown in Figures 1-4, in one embodiment, an insole that adapts to the arch of the foot is provided. The insole that adapts to the arch of the foot includes a main body layer 1 and a support layer 2. The support layer 2 is arranged at the arch of the main body layer 1.

[0022] In this embodiment, the main body layer 1 forms the main body of the insole, while the support layer 2 is only provided at the arch of the foot, not at the toe or heel. The support layer 2 provides support for the arch of the foot, thereby relieving fatigue or pain caused by an unsuitable shoe and making exercise more convenient.

[0023] Preferably, a support sheet 3 is provided between the main body layer 1 and the support layer 2, and the support sheet 3 can be provided in three ways: first, the support sheet 3 is provided on the inner and outer sides of the arch of the main body layer 1; second, the support sheet 3 is provided on the inner side of the arch of the main body layer 1; third, the support sheet 3 is provided on the outer side of the arch of the main body layer 1.

[0024] In this preferred embodiment, three insole settings are provided, which are respectively suitable for people with low arches, people with high arches and people with normal arches. The first type is for people with normal arches, the support sheet 3 can be set on both the inside and outside, or the support sheet 3 can be not set, such as Figure 1 The second type, in which the support sheet 3 is arranged on the inner side of the arch, is suitable for people with low arches, because the inner side of the foot needs support, such as Figure 2 The third type, the support sheet 3 is arranged on the outside of the arch, which is suitable for people with high arches, because the outside of the arch needs support, such as Figure 3 This preferred solution adapts to different arches of the foot according to the different arrangement positions of the support sheet 3, meeting the needs of various different groups of people.

[0025] Preferably, a plurality of openings 4 are provided on both the inner and outer sides of the support layer 2. The shape of the openings 4 is rectangular or triangular.

[0026] In this preferred embodiment, a plurality of openings 4 are provided on the inner and outer sides of the support layer 2 near the heel, which serve to reduce the wrapping strength of the mid-hindfoot while providing space for retreat to better adapt to the shape of the foot.

[0027] Preferably, a plurality of pressing protrusions 5 are provided on the support layer 2 .

[0028] In this preferred solution, the pressure protrusions 5 are provided at the weak position of the edge of the support layer 2 , and their shapes can be circular rings or parallel lines, and their function is to increase the thickness of the support layer 2 and improve the strength of the support layer 2 .

[0029] Preferably, the insole adaptable to the arch of the foot further includes a fabric layer, and the fabric layer is arranged above the main body layer 1.

[0030] In this preferred embodiment, the fabric layer is breathable, providing a sweat-resistant and breathable surface, preventing sweat from accumulating on the foot. The fabric layer is positioned above the main body layer, directly contacting the foot. Several anti-slip bumps are positioned near the heel of the fabric layer to increase friction and prevent slipping during exercise.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
