I do think it's important to wear compression socks/sleeves during a long flight.
Agree. This what compression socks were designed for and makes me wonder why anyone would wear them when running. When heart is pumping during running, there is no risk of blood pooling. In fact, wouldn't compression socks inhibit blood flow to the calves where you would want it?
i think someone got a great return on investment when they paid paula radcliff to wear compression socks and she set the WR run.
