Strassburg sock advice needed

I purchased some strassburg socks in hopes of improving my PF but I'm having issues wearing them at night. I'm short so the socks literally come all the way up to my knees. I have to pull the straps all the way down and even have some velcro sticking up just to pull my toes up.

My problem is that the top elastic of the sock tends to roll down a bit in my sleep and it gets tighter and digs into my skin. It's painful so I end up pulling the socks off halfway through the night but that defeats the purpose.

Does anyone have suggestions on how to help that? I've tried bunching the socks near my lower shins to wear the socks lower on my calves but doing that makes it even harder to get the needed tension from the strap. I appreciate any advice
