4. Take off your shoes whenever you can; don't wear shoes at home (or change to slippers /sandals).

No No No No No. That is the one that kills the coworkers. Once you put on any shoes in which your feet produced odor it is already too late. The chick in my office came to work and took them off immediately and it still got bad. She tried all the normal crap and I am sure she was washing her feet because she was extremely self-conscious about it (she mentioned that her new husband was struggling with it too). Powders, inserts, and a foot baths none of it worked. The spray anti-perspirant was cheap and easy and it was an immediate relief and a total success. I wrote her a check to buy several new pairs of shoes. I wouldn't be this helpful except that foot odor can be as bad a body odor. That shit ruins the entire day of everyone around you. Flatulence goes away but foot odor lingers. I swear I could come in on saturday and still smell it in her office. It was like the seinfeld car thing.
