I shower every day but only because society says I should (plus I work in a hot sweaty kitchen). However, I believe soap is the reason you develop smells in the first place. Why? Well, I never, ever wash my feet with soap, only water, and because of that, I've never had smelly feet, ever. Even my 2 yr old work shoes, worn 5 days a week from 10am till 10pm still smell new. And I'm not even joking.they literally smell new still. I think deodorant makes you smell too. I again use it most days, but I noticed on the days I do use it, my pits begin to smell quicker than on days I don't use it.
