Hi Medity Health Team, I have just started wearing the socks this weekend and I am super impressed. They have helped the issue of swelling in my knees. I have had both knees replaced but the most recent one continues to swell when I stand for a few hours- for instance doing house chores. They give my knees relief from the swelling. And they feel good on. It feels like waves of electric pulses moving up my legs! In a good way though! Haha! The size chart is exceptional because the pairs I ordered fit well, and are the correct calf size and shin length and are just the right tightness. The directions for putting them on are very helpful and I’ve had no issues. That was brilliant whoever thought of that. Again, super impressed. Thank you, Susan Oconnell
