Thule! wing bars.
I've had mine for 7 years, really good, never fallen off.
Take them off when you aren't using them though or they will mark the paint and damage the door rubbers. Also if it absolutely tips down, you can get a bit of water ingress.
Don't leave them on the car beyond needing them.
That's not a Thule problem, its just how any bars attach to a gutterless, mounting point free car like a Golf Mk7.
That reminds me, gotta swap the feet over for some Mk8 ones - I think they might be different.
