I would recommend TXG socks
“I have an elevated risk of DVT due to my birth control. My travel doctor recommended that I get travel socks, but having bought cheap ones from a department store before, I wanted something that would give me confidence while travelling. I’ve also got some pretty chunky calves so I wanted to make sure I got a good fit. The benefits I found from wearing my TXG socks was no swelling of my feet, no soreness at all and no DVT. I would recommend TXG socks, the buying process was easy and I was confident I was buying the right size. The socks arrived quickly and fit like a very tight glove. Price -wise, it wasn’t much more than the other socks I’ve seen in stores but the extra touches were nice. “
