Where are Obama's shoes?

Referencing a 2007 speech from then-candidate Obama,

If American workers are being denied their right to organize and collectively bargain when I'm in the White House, I will put on a comfortable pair of shoes myself, I will walk on that picket line with you as President of the United States of America. Because workers deserve to know that somebody is standing in their corner.
