Very long (over knee) warm chunky socks that don't fall down?

[QuimReaper]

I want some cosy socks that come at least to over the knee, soft cosy (ideally chunky cable knit) ones, not tight cotton type ones, but which won't end up around my ankles.

Has anyone ever found such a gravity-defying unicorn?

Thanks!

I have a few pairs of these, they are soft, super warm, long (knee length on me and I am 5”9) and don’t fall down.
