Insole with ventilation arrangement
In one embodiment a shoe insole includes a top ventilation fabric, a bottom ventilation fabric, and a plurality of spaced resilient pillars (e.g., EVA, PU, or PVC) with a channel network formed among the pillars. The invention can effectively remove air and condensation between a wearer's sole and the bottom ventilation fabric to the atmosphere through a plurality of escape paths through the channel network. In another embodiment, a mesh structure is completely filled in the channel network.
1. Field of Invention
The invention relates to insoles for shoes, and more particularly to such an insole having an improved ventilation arrangement.
2. Description of Related Art
Shoe insoles have ventilation arrangement are well known. A conventional insole 1 is shown in
However, the well known insole 1 suffers from a disadvantage. In detail, the bottom of each opening 2 is blocked by the midsole 3. Hence, air is defined to circulate within each opening 2 when a wearer's foot presses on the insole 1. This can hinder ventilation, thereby undesirably causing smell (i.e., not hygienic). Thus, the need for improvement still exists.
SUMMARY OF THE INVENTIONIt is therefore one object of the invention to provide a shoe insole comprising a top ventilation fabric, a bottom ventilation fabric, and a plurality of spaced resilient pillars with a channel network formed among the pillars. By utilizing this, air and condensation between a wearer's sole and the bottom ventilation fabric can be sufficiently and effectively removed to the atmosphere through a plurality of escape paths including the channel network.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
A channel 21 is formed between two adjacent sides of any two adjacent resilient pillars 20. That is, a channel network is formed. The resilient pillars 20 are formed of a plastic material such as EVA, PU, or PVC. Also, the resilient pillars 20 can be divided into a plurality of zones in which the resilient pillars 20 in one zone may have a softness (or stiffness) different from the resilient pillars 20 in another zone so as to be adapted to different areas of the foot sole. This can be achieved by producing the zones with different compositions of plastic.

Claims
1. An insole for shoe comprising:
- a top ventilation fabric;
- a bottom ventilation fabric; and
- a plurality of spaced elastomeric members secured between the top ventilation fabric and the bottom ventilation fabric to form a channel network.
2. The insole of claim 1, wherein each elastomeric member has a cross-section of hexagon.
3. The insole of claim 1, wherein each elastomeric member has a cross-section of L.
4. The insole of claim 1, further comprising a mesh structure filled in the channel network and secured between the top ventilation fabric and the bottom ventilation fabric.
