Help needed to buy flight socks.

[ilovemykindle]

I'm going on a plane and have been advised to wear flight socks to stop my ankles swelling.
This is the only time they swell. I know to drink water and move about. Gp told me just to go to the chemist and buy some.
Do I wear/buy my shoe size 4. Are bamboo socks best. Open toe or full sock.
Thanks

I wear these very attractive Scholl flight socks! I tend to put them on at the gate when boarding is just starting. I've only worn them during long-haul flights. They are just about OK to wear. I wear the size that fits ladies shoe size 3-6 but you may need to measure your calf size too.
