Long plane flights are the kiss of death for older people who get swollen ankles. No matter how you fly (though I am not very familiar with Business travel) you cannot be walking around the plane enough to prevent swollen ankles and possibly blood clots and thrombophlebitis. I like that they are sensible and a little sassy, too. I have one set of others that are as good. The only problem is that I am short and the tops of the socks come up a little high and folding them down seems to irritate my below knee area. I expect it would not be a problem for taller people. Great product cannot fly without them.
