[0004] To achieve the above-mentioned purpose, the utility model provides a palm-type insole, comprising an insole fabric layer and a palm layer, wherein the palm layer is pressed and formed by palm fibers, and the palm layer has an elastic loose porous structure. The palm layer is located at the bottom of the insole fabric layer, and the insole fabric layer and the palm layer are fixed together by hot pressing.

[0005] Preferably, the insole material layer is configured as cloth.

[0006] Preferably, the rear end edge of the palm layer is provided with a U-shaped protrusion structure located at the periphery of the rear heel, and the edge of the middle waist portion of the palm layer is provided with an arch support protrusion structure corresponding to the position of the arch of the foot.

[0007] Preferably, an anti-mildew and anti-bacterial layer is provided at the bottom of the palm layer, and a PU foam layer is provided at the bottom of the anti-mildew and anti-bacterial layer.

[0008] Preferably, the anti-mildew and antibacterial layer is configured as a silver ion coating layer.

[0009] Preferably, the top and bottom of the PU foam layer are penetrated by a plurality of air holes.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model has a simple structure and reasonable design. It is provided with an insole fabric layer and a palm layer. The palm layer is configured to be a loose porous structure formed by pressing palm fibers and having elasticity. It has good air permeability, good water and sweat absorption effect, moderate hardness and can improve the comfort of the insole.

[0012] 2. The insole fabric layer of the utility model can be directly fixed together with the palm layer by hot pressing, without the need for glue, without odor, safe and environmentally friendly.

[0013] 3. The palm layer of the present invention is thicker and can be used as the midsole of a shoe sole, so that the shoe sole matched with the palm layer does not need to be provided with a midsole. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] Example 1

[0020] Please refer to Figure 1 and Figure 2 Embodiment 1 of the present invention provides a palm-type insole, comprising an insole fabric layer 1 and a palm layer 2, wherein the palm layer 2 is located at the bottom of the insole fabric layer 1. The various components of this embodiment are described in detail below with reference to the accompanying drawings.

[0021] The insole material layer 1 can preferably be configured as cloth, which is convenient for hot-melt connection with the palm layer 2 .

[0022] The palm layer 2 can be formed by pressing palm fibers, and the palm layer 2 is a loose porous structure with elasticity. The thickness of the palm layer 2 can be preferably set to 0.3 cm to 1 cm.
