I don't really need therapeutic socks and consider my 5'6, 130 pound frame to be about average, but all the socks at the stores squeeze the circulation out of my calves.  These socks stay up well, keep my feet warm, but not sweaty, and have the added benefit of being aloe-infused.  I expect them to last a very long time.  Since it has been such an ordeal to find good quality socks, I plan to hand wash these and may even buy another pair.
