"Zieh deine Schuhe aus!"
Übersetzung:Take off your shoes!
Sometime the German preposition "aus" can be translated "out" but other times it should be "off". We don't use the preposition "out" like that. If your shoes were in a box, you could take them out. But we put clothing "on" and "off" our bodies. The only time you would take something out of your body would be if it were IN your body. Someone might say that they took their earrings out, but even here it would be just as acceptable to "take them off". But you definitely don't want shoes "in" your body, so you should never have to take them "out". I hope that helps.
