1. Literally, to not completely pick up one's feet when walking, so that they drag with each step. Please stop dragging your feet, you're going to wear out the soles of your shoes.
2. To move slowly and reluctantly because one does not want to do something. We can't be late for the dentist, so quit dragging your feet and get in the car!
