A kind of elastic insole

Abstract

The invention relates to an insole, which provides an elastic insole that improves wearing comfort and has lasting softness, elasticity and air permeability, including an insole body, the insole body is a thermoplastic elastomer, and the insole body corresponds to the sole of the foot. The heel, the arch, the metatarsal and the toe are respectively divided into the heel area, the arch area, the metatarsal area and the toe area. The heel area and the arch area on the lower surface of the insole body are arranged in sequence along the length direction of the insole There is a row of circular protrusions, the row of circular protrusions is composed of a plurality of circular protrusions, a first circulation groove is arranged between adjacent rows of circular protrusions, and a flow groove is arranged in the first circulation groove The first ventilation hole; the metatarsal region and the toe region on the lower surface of the insole body are provided with second circulation grooves intersecting and intersecting; the second circulation grooves are provided with second ventilation holes; the upper surface of the insole body A breathable interlining layer is laid on the surface, and the interlining layer covers the first air hole and the second air hole.

Description

technical field [0001] The invention relates to an insole, in particular to an elastic insole. Background technique [0002] Shoes are one of the indispensable daily necessities in people's daily life. People wear shoes for work, outdoor activities, various sports, etc., and the soles of shoes have different materials in order to adapt to different applications. Different materials have Different physical properties, people buy shoes according to the conditions of use, and the soles cannot be replaced, so a large number of shoes need to be hoarded. Therefore, people often lay insoles in the shoes and use the insoles to improve the comfort, breathability and elasticity of the soles, etc. effect, and the insole is not fixed in the shoe, one insole can be applied to various shoes, can be used repeatedly, and has strong practicability.

Problems solved by technology

[0003] Most of the current insoles are made of cloth. Cloth insoles have poor air permeability and require sewing operations. The production cost is high, and they are light and thin, so they are not comfortable enough. To achieve air permeability, but the aperture is small, the insole is thin, and the air permeability is poor; and the current insole, in order to prevent the wearing discomfort caused by the easy separation of the insole and the sole during walking, the bottom surface of the insole is set as a plane to achieve the insole. The complete fit of the sole makes it difficult for the insole to separate from the surface of the sole. In this case, the small holes on the insole will be blocked. When the foot is stepped on, the small holes are actually closed, and the air permeability is not achieved, and the ventilation effect is poor; now Some insoles are made of elastic material (such as silica gel), and use the elastic deformation force of the elastic material to provide a comfortable wearing surface for the soles of the feet, and set protrusions on the upper surface of the insole, and set air holes on the non-protruding positions of the upper surface of the insole, so that the soles of the feet When stepping on, the air vent openings on the upper surface of the insole are not blocked, but, in order to fit the insole to the sole, the lower surface of the insole is still a flat design, and the air vent openings on the lower surface are still sealed, and the air permeability effect is improved. It is still not good, and the insole of the plane structure is under the action of force, the force point is too concentrated, the force concentration is not scattered, the shock absorption effect is not comprehensive, and the shock absorption effect is poor.
