Punch Odour Destroyer Insoles

I was looking for a good insoles the other day and finally grabbed this one

The main reason was this one has added charcoal and it really does smell like carbon. I don't mind that because they are going to sit in my shoes all the time. It claims that it has antibacterial agent to combat those bacteria that cause odour. The spec
   1. It has dashed lines according to sizes so that it is easy to cut the insoles into appropriate/chosen sizes.(You can see I was half way cutting them, the right side still needs to be cut)

   2. It is about 4mm thick. It feels like soft rubber foam. So the carbon must have been embedded or blended into it.
   3. It has perforations for foot to breathe
   4. White fabric layer. This will face up so that it will be in contact with your sock instead of the grey carbon layer.

Verdict:
     For about US$4, I am satisfied with the insoles. It refreshes the feel of my boots. It is thick enough to support my weight
