Abstract

The invention discloses an insole capable of holding thermal insulation materials in an interlayer. The insole comprises an insole body, a cavity is arranged in the insole body, an opening is reserved on the side face of the insole body and communicated with the cavity, a thermal insulation layer is arranged inside the cavity and enters the cavity via the opening, the transverse section of the opening is rectangular, and the cubiform cavity is disposed in the inner middle of the insole body. The insole is simple in structure and convenient to use and has a thermal insulation function.

Description

technical field [0001] The invention relates to an insole, in particular to an insole in which thermal insulation materials can be placed in the interlayer. Background technique [0002] In the prior art, such as patent ZL88104047.9 discloses an insole with upper and lower layers; the upper and lower layers of the insole are connected together along the perimeter to form an airtight or non-airtight central cavity; Many pillars between the upper and lower layers elastically support the upper layer of the insole; these pillars form a whole with the upper and lower layers of the insole, and the material of the insole is a synthetic resin that is easily deformed; these pillars form a hollow cylinder that can be elastically deformed, The shock absorption and ventilation of the insole are increased to the maximum, while the thickness of the insole is reduced to the minimum. Another example is patent ZL201010500013.7 which discloses an insole. A front bottom is arranged on the for...
