Nice try, but you didn't make it with me.

My understanding of what you are trying to say is: You believe that the soles of shoes can be customized like a rubber stamp to leave an imprint on surfaces that we walk upon. Perhaps a colored volatile solution that evaporates totally so that it does not damage any surfaces could keep the "inked surfaces" moist. From a liability standpoint, I don't know if this is a good idea or not. This borders upon graffitti.

Thanks for the interpretation. It's an interesting concept. Perhaps useful in children's shoes for tracking them down by leaving some sort of temporary scent or trace to be followed if they get lost.

I like your idea, from both an entertaining concept and as a new way to express one's views. It seems somewhat like a throw back to pre-historic times as a way to communicate. Perhaps that is what makes it so intriguing. Of course the chemical that you use to illustrate your point of view would have to fade and be environmentally friendy. This would be a lot better than the graffiti that you see in the states today. Good idea.

Adults tend to think in terms of walking on pavement. If you were walking on mud, then the tread pattern would be left naturally. Kids would love this, though their mothers might not like encouraging them to walk in the mud. If they were customizable, you could have you kid's name on them. You could track down your kid really easily over muddy ground!
