I've had a hard time finding compression socks that don't completely cut off my circulation, but finally found a pair. I am taking a high blood pressure medicine that causes fluid to build up in my ankles. I flew from Arizona to New Orleans and walked for hours and my feet and ankles didn't swell. The socks were actually comfortable as well. My legs are tree trunks haha So normally compression socks squeeze way too tight. These were comfortable but still did their job. The one tip I would give is if you are going to be doing a lot of walking or exercise in these I would suggest wearing little ankle cotton socks underneath as when my feet started to sweat it wasn't as absorbent and got a little slippery. Overall very happy with the product.
