Using compression socks for the first time, need tips!

I have a trip coming up with a long flight, a lot of walking, and a really packed schedule. I've always heard that compression socks help with longs flights, so I picked a few pairs from dr woof for me and my partner. They already arrived, feels good and fits us well.

I just have a few questions since I've never used them before:

• Is there an easier way to put them on? I'm having a bit of trouble with that.
• Should I only wear them during the flight and switch back to regular socks after or can I wear them all day while walking? Also, do they help with leg pains from walking a lot?

I'd appreciate any input on this!
