I personally prefer NOT to wear shoes. Even after coming home from a formal event, sometimes when I go back out I'm still wearing a suit and tie, but I slip on my flip flips (aka sandals, aka "thongs", aka slippers), lol.
At all times possible I try NOT to wear shoes unless it's dreadfully cold outside or I'm at a formal setting or work.
At all other times, my feet are o-naturale!!!
