I love walking barefoot. Unfortunately, I broke my foot snowboarding a few years ago, tearing some ligaments that hold my arch up. It's supposedly fixed, but it hurts if I walk without my orthotics too much. I still walk barefoot as much as possible though.

Also kind of tough in the winter in MN. Your feet tend to freeze to pavement below 0 F, so you always wear boots outside in the winter. You have to re-toughen your feet every spring.
