Q: Maybe with special elastic inserts? My present hose are already flat knitted to measure. I’m concerned about the wrinkles [behind knees] when one is not standing. Is there any manufacturer that provides special inserts?
A: You need to get a custom fitted pair of stockings. These will not be small, medium and large. With a proper fitting pair of stockings, this will not occur. Inserts are not needed if the stockings fit correctly.
