Abstract
An insole includes an insole body made of a breathable foam material, a fabric layer unit bonded to the insole body along a stacking axis, and a plurality of air holes. The insole body has a bottom surface, a top surface, and a plurality of air voids spatially interconnected and capable of connecting to the bottom surface and the top surface. The fabric layer unit includes a fabric layer and a waterproof membrane. The waterproof membrane is disposed between the fabric layer and the insole body, and is bonded to the top surface of the insole body. The air holes are connected to the fabric layer and the waterproof membrane. The air holes and the air voids are spatially interconnected. Each of the air holes has a hole width of less than 0.1 mm. The air holes and the air voids together form a plurality of air channels.
Claims5
An insole, comprising:
- an insole body made of a breathable foam material, the insole body having a bottom surface, a top surface that is opposite to the bottom surface, and a plurality of air voids that are spatially interconnected and are capable of connecting to the bottom surface and the top surface;
- a fabric layer unit bonded to the insole body along a stacking axis, the fabric layer unit including a fabric layer and a waterproof membrane that is adhered to a bottom surface of the fabric layer, the waterproof membrane being disposed between the fabric layer and the insole body, and being bonded to the top surface of the insole body;
- and
- a plurality of air holes connected to the fabric layer and the waterproof membrane, the air holes and the air voids being spatially interconnected so as to together form a plurality of air channels, each of the air holes having a hole width in a direction perpendicular to the stacking axis of less than 0.1 mm.
