Shoes?

Rating: 5/10 (17 May 2020)

Maybe this is so trivial but wonder in the real situation people were wearing shoes and not think to go barefoot to avoid being heard by the terrorists. There was this scene when the guy ran across the lobby to the elevator and I'm sure one of the gunned man would hear him, he was very close. Well it's a movie based in true events so,were they really wearing shoes or shoes were added for dramatic effect?
