This exercise will improve the active control of your toes.
Start by trying to lift the big toe off the floor without lifting the other toes. Then try to lift your little toes while keeping your big toe down. Hold the toes up for 5 seconds and switch. If you have difficulty separating the toes, you can assist little toes with your hand while trying to lift the big toe and then the little toes. Complete 10 repetitions of each on both feet.
