Thanks for the replies.
That's good to know. That device looks useful, maybe I'll consider it in the future with the stronger compression. So far it's not that problematic to put them on.
I guess you're right, I'll have to see for myself.
To be honest I wanted to start with 30-40 but then thought it might be too much as I never had to wear any compression garments before. I'll wait for my current stockings to wear out before moving a class higher.
