The Specificity of Removing Shoes from the Feet

בכור שור – 3:5 “של נעליך מעל רגליך” – Moshe is told to, “Take off his shoes from his feet.” Why does Moshe need to be told to take off his shoes from his “feet”? Where else would he take it off from? What people cover their hands with (gloves) are also called, “נעל ”, and thus it needed to be specific that he takes off his נעל from his feet, and not that he needed to take off his נעל from his hands.
