They were to go with common shoes on their feet, and not to take two coats.

And the people from whatever place that does not welcome you or listen to you, when you leave there, shake the dust off from under your shoes as evidence against them." [Note: This was a Jewish custom showing disdain and intended to suggest their unworthiness].
