From the pictures I saw that they can be worn over the knee, or folded down.
They looked so promising! And they were such a good deal at $69. Other websites are selling them for like $149. But when I received them I was rather disappointed. The material is very thin and flimsy. They don't really have shape and won't stay up well on their own, except the foot area. I wish the shaft had more of a structure to them! So sadly, these are not going to work for me and I have shipped them back.
Oh well, money saved! I can continue my New Years Resolution of not spending as much money lol.
