Washable Dress Shoes

I perhaps don't win the award for worlds sweatiest man but I am certainly above average on the Iowa Standard Sweat Index.  It's all good when I'm exercising, I'm dressed for the occasion and my shoes are expected to smell that way.  But my poor dress shoes.  They stink on the inside and they still look like they could last two years on the outside.  A solution would be to create a shoe that looks fantastic on the outside and can be thrown in the wash on a weekly basis.  In fact a shoe that could be washed in a washing machine once a week would take off not just in dress shoes but in everything.
