Compression socks

[Swissroll12]

Hi , I’m going on a long haul flight from the Uk to Brazil I’m in my 50’s so recommended compression socks , can anyone recommend a good brand please and which 15-20 mmHg or 20-30 .
My ankles are prone to swelling

I have some from ‘Not your Grandmas’ they are really nice and not the type that are impossible to put on and off.

I just get ones from Amazon. Choose foot size and they’ve worked. Get up and walk about in the plane if you can.
