How do I wear footless tights? Help!? - footless legging tights

I bought a pair of legs Affair Opaque footless stockings. You are with lace and one size fits all ". I'm so confused, you get to the ankle or in the middle of the calf?

I may take half of my knee, calf or hand me a little, but too long and are still falling and I can not pull back all day.

They are so cute! Help? :)
