I wear compression socks because my first DVT and the swelling with it damaged the veins so that blood pools, even without any other evidence of the pooling. That's what my hemo thinks caused the second DVT.

My favorite are the Jobst ActiveWear over-the-calf socks https://www.amazon.com/dp/B001O1IQY6

They are thick like sport socks. I also like Jobst for Men dress socks, and a third place choice is the Gold Toe compression socks.
