My husband and I used these compression socks for long haul flights this year - Brisbane to Athens return, and Brisbane to New York return. We put them on before boarding the plane and taking them off upon landing. My legs usually swell up badly on long flights, but these socks appeared to do the trick. I experienced little to no swelling. I did not feel any discomfort from wearing them and the same for my husband. I only wish they were made just plain black, without the sporty design on them, so they could be worn for dressier occasions when I am on my feet for long periods of time. But they are now part of my travel essentials for any flights.
