I was diagnosed with venous insufficiency about a year ago. I had purchased, prior to copper flux knee highs , some five different brands, including from the doctors office; all were beneficial. When I saw the add for copper flux, the price was too reasonable to not try; im glad I tried. The copper flux were superior in these ways: 1 best therapeutic results based on visual observation of swelling at the end of a full on my feet day and physical touch of ankles and calves reduced edema/pooling of venous fluid/less swelling; 2 easiest to put on and take off ; and 3 best feel when wearing feels really supportive, while not feeling constraining. So, Im really happy I tried the product and grateful for pulse for allowing for the pricing for someone on a fixed income/tight budget.
