They weren't intended to be worn with slacks.  They started out as
boat shoes because of the non-slip sole.  For some reason, people
thought that they were fashionable.  Crocs should go back and target
the people that use them for their functionality...  Everyone that is
required to wear non-slip soles at work such as waiters, cooks, also
incoming freshman who need something to wear in the showers at the
dorms, and doctors and nurses who are on their feet all day... crocs
don't look bad with scrubs.  I'm sure there is a million other
industries that could use crocs for their functionality.  Also, the
whole medicare thing, if insurance will pay for crocs for diabetic
patients, think about the opportunities there.
