I wrote a similar post to this some months ago but I extended and updated it for the Living Barefoot site. It's about how my feet have changed over the last two years since I switched from wearing conventional shoes to minimalist shoes.
I think it accurately captures the changes that I've noticed in my own feet. I don't know if others will experience the same kinds of changes but most, I think, will experience some similar changes.

(And the pictures are of my feet. ;) ).
