Hi,

I'm very convinced by the idea to go barefoot or with minimalist shoes.
Accordingly I recently purchased both Fiverfingers and Evo shoes.
I was quite surprised to see that these shoes- which I thought were marketed more to back to nature people- are treated in a way to prevent bad smell. The technology is called Agion and is based on silver.
Now on their website http://www.agion-tech.com/ they write that it is all natural and safe.
Still I'm not so sure if I read something like this: "Fighting microbes in three ways
Silver ions attack multiple targets in the microbe to prevent it from growing to a destructive population. This tri-modal action fights cell growth in three ways:

1. Prevents respiration by inhibiting transport functions in the cell wall
2. Inhibits cell division (reproduction)
3. Disrupts cell metabolism"

This is of course aimed at the microbes. But how do I know that this stuff won't mess with my cells?

I'm quite disappointed to find that the marketers have added high tech stuff to something that is supposed to be back to nature.
But I'm absolutely uneducated on this kind of bio-chemical stuff. So it would be great to hear if someone is knowledgeable about it. Other people must have wondered about this too. It actually reminds me of Teflon coating in frying pans.
